Knife Review: Morakniv Kansbol with Multi-Mount

Released along with Morakniv’s Garberg and Eldris models, this knife is actually an update of their classic and very popular ‘2000’ Hunting knife. Headlined as Morakniv’s “Primary All Round Knife” – meet Kansbol.

The Blade and Handle Geometry:

Most knife specifications have a basic description of the blade geometry, but in this section I will be taking a more detailed look at geometry and balance.
 photo 16 Kansbol grind P1250033.jpg

Using a set of gauges and precision measuring equipment including a Vernier protractor, callipers, fixed radius gauges and the unique Arc Master adjustable radius gauge (the one that looks like a crossbow).
 photo Knife measuring P1180483.jpg

These measurements have been tabulated and are presented along with a few reference blades (8″ Chef’s Knife, 5.5″ Santoku and the popular Fällkniven F1).

Key aspects such as the primary bevel angle, grind type, blade depth, blade thickness, length, weight are detailed, along with balance information.
 photo 17 Kansbol angle P1250040.jpg

The ‘Balance relative to the front of the handle’ tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The ‘Balance relative to the centre of the handle’ indicates how close to a ‘neutral balance’ the knife has in the hand.
 photo 15 Kansbol balance P1250032.jpg

In the case of full convex grinds the approximate centre of the grind is used for the primary bevel angle estimate.

The blade is made from 2.5mm Swedish stainless steel 12C27.

Explained by the Maker:

The reasons for certain design choices may not be clear when simply looking at an object, so this section is intended to give an insight into the thinking behind a design by speaking to the designer themselves.

Unfortunately I can’t always get time with the designer so will use this section to include relevant information about the knife and its designer.

This is an interview by Tactical Reviews with ‘Head of Production’ at Morakniv, Thomas Eriksson, from IWA 2017.
The discussion includes how the factory edge is created, maintained and also includes micro-bevels and zero-grinds. It is 16 minutes long, so you might want to come back to this after reading the rest of the review.

A few more details:

As with the recently reviewed Garberg the Kansbol has a standard , and Multi-Mount version. As before, the standard version shows the knife on the front of the box, and the Mulit-Mount version, the knife in its sheath and mount.
 photo 01 Kansbol boxed P1240609.jpg

Starting with the standard version, out of the box, the belt loop is not locked into place.
 photo 02 Kansbol unboxed P1240612.jpg

You can see the proudly displayed ‘1891’ (the date when it all started for Morakniv).
 photo 03 Kansbol 1891 P1240613.jpg

The belt loop can easily be removed if you would like to use the click-lock sheath on its own. (Click-lock is a system where lugs in the sheath click into corresponding depressions in the middle of the handle to securely hold the knife in the sheath, even when worn round the neck.)
 photo 04 Kansbol belt loop P1240617.jpg

For normal belt mounting, just push the belt loop all the way to the top until it clicks into place. Once fitted to your belt, you can pop the sheath out of the belt-loop ring leaving the belt loop on your belt so you can stow the knife elsewhere.
 photo 05 Kansbol belt loop on P1240620.jpg

Immediately distinctive, even within the Morakniv range, the dual-grind all-round blade of the Kansbol.
 photo 06 Kansbol blade P1240637.jpg

The spine has been ground to have sharp corners for striking sparks from ferrocerium rods.
 photo 07 Kansbol blade spine P1240638.jpg

With its Scandi-grind, thanks to the additional profiling that thins the front section of blade, it gives the blade a very different appearance to the standard Scandi-grind blade we are used to.
 photo 08 Kansbol blade P1240641.jpg

Much like the Garberg, the Kansbol has the symmetrical handle that allows for forward or reverse grips, but the Kansbol also has a TPE (a rubbery polymer) coating over the polypropylene handle core.
 photo 09 Kansbol butt P1240642.jpg

Next up is the Multi-Mount version. In the box, all the components are slotted together.
 photo 10 Kansbol MM out of box P1240652.jpg

Included are the plastic holster, a belt loop, a locking strap, three hook and loop straps and the multi-mount itself.
 photo 11 Kansbol MM parts P1240657.jpg

The simplest configuration you can use the Multi-Mount, is to have the bare sheath held in the mount with a hook and loop strap. The click-lock of the sheath keeps the knife in place.
 photo 12 Kansbol MM basic P1240769.jpg

For total security, the locking strap can be added.
 photo 13 Kansbol MM locking P1240775.jpg

Turning the Multi-Mount over, you can see how the locking strap is fed through the mount and will keep everything in place even if the hook and loop strap failed.
 photo 14 Kansbol MM locking under P1240778.jpg

What it is like to use?

Morakniv are extremely good at making comfortable knives, and though the Kansbol’s handle is not shaped in the way the Companion and Bushcraft models are, you can work with it for hours on end. The handle is a size that will work well for almost anyone (I take XL size gloves), and in line with many of the other Morakniv knives, the blade length is easy to wield for all those every day tasks.
 photo 10 Kansbol in hand P1240645.jpg

As you would expect, the Scandi-grind of the Kansbol takes all things wood related in its stride. What is not shown here is the fact that the additional profiling of the forward section of the blade makes it well suited to many tasks a standard Scandi-grind blade is not. This includes food preparation, and game preparation where the slimmer blade cuts deeply much more easily.
 photo 18 Kansbol whittle P1250215.jpg

Before jumping to the Multi-Mount, something to mention about the belt loop, is that thanks to its click-fit to the sheath, you can easily remove the sheath from the loop, and stow the knife in you pack, leaving just the loop on your belt.
In the Garberg review, I showed the Multi-Mount fitted to the back of the rear seats of my car. As the Multi-Mount is so versatile and opens up so many options, there are far too many to show, but to illustrate just one, in this case I’ve used the hook and loop straps to fit it to a walking stick.
 photo 19 Kansbol MM stick P1260339.jpg

I’ve been appreciating how useful it is to have the knife to hand like this, but in the UK this is really only suitable in more rural areas where the sight of a working tool does not cause distress to anyone.
 photo 20 Kansbol MM stick P1260344.jpg

Although the Kansbol will work hard, I’d not choose to be batoning with it too much. Given its proper place as a general purpose knife, it does this job fantastically well. Hopefully by re-launching this knife blade (from the ‘2000’ model), Morakniv will bring the benefits of the profiled blade more into the limelight.

Knife Review: Morakniv Garberg with Leather Sheath and Multi-Mount

Morakniv have released their first (long awaited) full tang knife, the Garberg. Dedicated Morakniv users have been asking for a full tang knife, as they want a hard-use version of the much loved Companion.

The Blade and Handle Geometry:

Most knife specifications have a basic description of the blade geometry, but in this section I will be taking a more detailed look at geometry and balance.

A few more details:

Morakniv did not stop at just making the Garberg full-tang. There are two versions of the Garberg available; one with a full flap leather sheath, and the other with Morakniv’s Mulit-Mount sheath system. The first to arrive at Tactical Reviews was the leather sheath.
The image on the front of the box for the leather sheath version just shows the knife. The Multi-Mount’s box shows the sheathed knife.
 photo 01 Garberg boxed P1220689.jpg

Straight out of the box the knife is hidden by the premium quality leather flap sheath. It is obvious straight away this is a very good quality sheath.
 photo 02 Garberg unboxed P1220692.jpg

A close-up look at the press stud shows the attention to detail with the Morakniv logo embossed around the edges.
 photo 03 Garberg press-stud P1220695.jpg

The stitching uses a heavy duty 1mm thread, cleanly punched though the 3mm leather and the welt.
 photo 04 Garberg stitching P1220698.jpg

On the back, the belt loop is made of the same thick leather as the rest of the sheath.
 photo 06 Garberg belt loop P1220706.jpg

The top of the belt loop is fixed with two rivets, and the bottom with a single rivet.
 photo 07 Garberg sheath back P1220709.jpg

Lifting the flap shows that the main sheath is a deep/full sheath.
 photo 08 Garberg sheath open P1220711.jpg

At the top of the sheath opening, the stitching is complemented with a rivet to prevent the stitching at the top from being cut and unravelling the sheath.
 photo 09 Garberg sheath open P1220715.jpg

And here we are, the Garberg.
 photo 10 Garberg knife P1220718.jpg

Moving in close to the tip you can see the Scandi-grind and the polished cutting edge’s micro-bevel (see the video with Thomas Eriksson, from IWA 2017).
 photo 11 Garberg tip P1220722.jpg

Unlike most of the Morakniv knives, the Garberg has a ricasso, and a nicely radiused Scandi-plunge-line.
 photo 12 Garberg plunge P1220726.jpg

With the Garberg being intended as a hard-use knife, the handle material is not just any plastic, it is a specially chosen extra-rugged Polyamide.
 photo 13 Garberg handle P1220728.jpg

The full tang is exposed at the butt allowing for maximum strength and hammering without damaging the handle.
 photo 14 Garberg butt P1220733.jpg

To make it ideal for use with ferrocerium rods, the spine has been ground to have sharp corners. The logo is laser engraved onto one of the blade flats.
 photo 15 Garberg spine1 P1220737.jpg

This sharp edged spine extends the entire length to the tip.
 photo 16 Garberg spine2 P1220741.jpg

Not long after, the multi-mount version arrived. Note the picture on the box shows the knife sheathed in the multi-mount instead of the knife on its own.
 photo 20 Garberg multi P1240783.jpg

This time there are many more parts in the box. Included are the plastic holster, a basic belt loop, a locking strap, three hook and loop straps and the multi-mount itself.
 photo 21 Garberg multi contents P1240786.jpg

Taking the most basic components, the knife and plastic sheath.
 photo 23 Garberg multi sheath P1240796.jpg

Your first mounting option is the belt loop. This loop is fixed to a plastic ring that slides up the sheath and clicks into place.
 photo 24 Garberg multi loop P1240799.jpg

Next up is the locking-strap used to ensure the Garberg can’t come out of the sheath whatever angle it is mounted. This strap can be used with the multi-mount for the highest security (but not with the belt loop).
 photo 25 Garberg multi flap P1240802.jpg

The locking strap is made of leather for maximum performance and durability.
 photo 26 Garberg multi flap back P1240805.jpg

The multi-mount has many holes and slots to give you a great many fixing options, from screw holes to MOLLE/PALS.
 photo 22 Garberg multi base P1240791.jpg

A hook and loop strap is used to hold the sheath in the multi-mount. The locking strap also threads through part of the multi-mount so will keep the sheath securely in the multi-mount even if the hook and loop strap fails. You can also use cable ties in place of the hook and loop straps for a more permanent fixing.
 photo 27 Garberg in mount P1240808.jpg

What it is like to use?

To start to understand where the Garberg fits in, in terms of how it feels to use, let’s start by looking at in alongside the Companion and Bushcraft Black.
 photo 17 Garberg compared P1220761.jpg

Immediately obvious is the Garberg’s symmetrical handle. This is not an accident, the Garberg’s handle has been specifically designed to allow it to be held in a forward or reverse grip for greater versatility. Overall it is no bigger than the Bushcraft model, but does feel much more solid. The extra weight of the full tang gives the knife a very different feel, even though the blade stock is the same at 3.2mm.
The line of the spine is very similar to the Bushcraft, but the blade of the Garberg has more belly which adds a little more forward weight and reduces the tip angle. We’ll get onto more of it ‘in use’ a little later.
 photo 18 Garberg compared2 P1220765.jpg

Just looking at the two versions of the Garberg, how do you choose between them?
 photo 28 Garberg comparing P1240812.jpg

Clearly the knives are identical, so it all comes down to the way you want to carry it. For belt carry it has to be the leather sheath every time. This is a hard wearing and comfortable sheath and simply won’t let you down. Traditional materials that have proven themselves ideal for the task have been used, and Morakniv have not scrimped on this, using only premium 3mm thick leather.
The multi-mount covers just about any other carry option and even has a belt loop suitable for occasional use.
 photo 29 Garberg comparing P1240816.jpg

Following the huge success of the Companion and other Morakniv knives, the Garberg is an ideal all-round size. A comfortable size and weight which is up to as much work as you would ever really want to put a knife to. Any more blade length starts to bring you into chopping territory and reduced agility for finer tasks, any less and you start to lose wood processing ability.
 photo 19 Garberg in hand P1220770.jpg

Out into its natural habitat.
 photo 33 Garberg outdoor P1250152.jpg

Batoning can be carried out with no concerns at all thanks to the full tang. The sharp edged blade spine gives good grip on the baton, but it does mean the baton gets chewed up faster. The only reason this strike did not go all the way through in one hit, is that I didn’t want to cut into the limb I was resting it on.
 photo 34 Garberg baton P1250202.jpg

You would barely notice that I had been batoning away with this for nearly an hour, apart from a slight smear of sap there is not a mark on it.
 photo 35 Garberg cut P1250211.jpg

Possible mounting locations for the Multi-Mount are so numerous, I’ll just leave you to think of a few yourself, but here is where the Multi-Mount Garberg is currently residing.
In this photo I’ve pushed the rear seats of my car forward slightly to make it easier to photograph. Amongst a few other bits of kit the Multi-Mount is held onto the seat back with the hook part of the large hook and loop straps. Make sure you leave room to lift the knife out of the sheath.
 photo 37 Garberg car P1250356.jpg

In this instance mounting it horizontally resulted in the mount gradually working its way downward due to bumps in the road slowly splitting the hook fastner away from the seat back. Mounted vertically this doesn’t happen. The main downside I see to the Multi-Mount is that it is mainly suited to permanent or semi-permanent mounting and may be slow to move to another location or bag.
 photo 38 Garberg car P1250360.jpg

Throughout the heavy workout I gave the Garberg, there was no evidence of edge chipping or rolling, so it looks like Morakniv have got the hardness and toughness just right. I’m happy to give this a hard time, much more so than the half tang models.

Gear Review: NITECORE SC2 Charger and F1 Charger / Powerbank

With so many chargers to choose from, it can be difficult to pick one, so you may be looking for those models with a little more to offer. NITECORE’s SC2 and F1 chargers both have extra features that make them stand out, so let’s see what they are.

A few more details of the F1:

Starting with the smaller F1. Well ‘smaller’ doesn’t do it justice, this is tiny. I must also point out straight away, that this is not just a charger, but it is a powerbank as well. (NOTE: The F1 is only intended for charging Li-ion cells and needs a Li-ion for use as a USB powerbank.)
 photo 01 F1 boxed P1200108.jpg

Along with the F1, you get two rubber bands which are used to secure an 18650 in the charging slot. This is for when you use the F1 as a powerbank and want the cell to stay in place when you carry it.
 photo 02 F1 box contents P1200126.jpg

At one end of the F1 is a micro-USB socket which is used for the input power to charge the cell fitted into the F1.
 photo 03 F1 input P1200133.jpg

Switching to the other end, the F1 has a full size USB socket which can provide USB power output up to 1000mA.
 photo 04 F1 output P1200135.jpg

The F1 contacts are gold plated.
 photo 05 F1 contacts P1200140.jpg

With a spring loaded sliding contact, the F1 can be used for any of the following Li-ion cells; 26650/18650/17670/18490/17500/17335/16340(RCR123)/14500/10440.
 photo 07 F1 slider P1200150.jpg

Underneath is basic information about the input/output ratings of this charger/powerbank.
 photo 06 F1 underneath P1200144.jpg

A few more details of the SC2:

With the SC2 we have quite a step up in power, and one of the headline specifications is a 3A charge current (if using 3A in one slot the other can only provide 2A), ideal for IMR or high capacity cells. This charger is compatible with a huge list of cells including both Li-ion and Ni-Mh cells.
 photo 01 SC2 boxed P1220057.jpg

With the SC2 you get a suitable mains lead (in this case a UK plug) and the instructions. Don’t throw those instructions away, you will need them.
 photo 02 SC2 box contents P1220065.jpg

Relatively plain looking the SC2 is full of functionality.
 photo 03 SC2 angle top P1220075.jpg

On the top end of the SC2 are the inputs and outputs. The yellow figure-8 socket is for the mains lead. There is also a 12V DC input for use in a car. Above the mains input is a full size USB socket which provides up to 2.1A USB charging output.
 photo 04 SC2 inputs P1220078.jpg

Considering its capabilities, the layout is very simple. There is an indicator panel (lights only, no digits are displayed), two control buttons, and the two slots.
 photo 05 SC2 top P1220083.jpg

On the underneath there are four rubber feet and the list of supported cells.
 photo 06 SC2 underneath P1220084.jpg

It’s a huge list of supported cells; IMR / Li-ion / LiFePO4: 10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340(RCR123), 16650, 17350, 17500,17650, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650
Ni-MH(NiCd): AA, AAA, AAAA, C, D
 photo 07 SC2 compatibility P1220088.jpg

The contacts are the typical chrome plated type.
 photo 08 SC2 contacts P1220095.jpg

A nice detail is that the NITECORE name is stamped into the slider contact.
 photo 09 SC2 slider P1220099.jpg

All the various options are selected using the two buttons. The C and V represent the Current and Voltage settings you can select.
 photo 10 SC2 buttons P1220100.jpg

When first powered on, the SC2 shows a set of lights indicating the default of 2A charging current.
 photo 11 SC2 lights P1220107.jpg

What are they like to use?

The F1 is one of those ‘don’t need to think about it, just buy it’ products for me. Combining the function of a Li-ion charger and powerbank into a tiny, easy to carry, device just makes it a must have EDC device.
When you insert a cell, it also tells you the voltage, so will work as a cell checker as well. If you use li-ions and have a smart phone, you will want one of these.

I’ve given the review sample a really hard time, with the worst conditions being the F1 having a 26650 fitted and used as a powerbank for a set of USB lights that try to draw 3A. Considering this should only output 1A, the actual output current was around 1.5A. Like this it was allowed to run constantly all day for a couple of weeks, swapping the 26650 when required. During this time the F1 did get hot, but expecting this to become a destructive test due to the extended abuse, I was impressed to find the F1 survived this without any issues.

For more details, have a look at the instructions by clicking on this image for the full size version. (Depending on your browser you might need to ‘right-click’ and ‘open in new tab/window’.)

Hidden within the casing are three green indicator lights. These tell you the cell voltage when inserting a cell, the remaining capacity when using as a powerbank, or the charging status when charging a cell.
 photo 08 F1 lights P1200154.jpg

The ideal cell for powerbank use is an 18650, and the supplied rubber bands fit this size cell perfectly. This is how it looks when you have it ready to carry as a powerbank.
It is important to note that there is parasitic drain when in Powerbank configuration which in the sleep/low power mode measures at 390uA. When using a 3100mAh cell it will take 331 days to drain the cell.
According to the YZX Studio Power Monitor, the output of the USB charging port is ‘Android DCP 1.5A’ meaning the D+ and D- lines are shorted.
 photo 09 F1 powerbank P1200158.jpg

Once you are back at home/work, just top up the cell with any USB charging point. Of course another major advantage of the F1 as a powerbank is that you can carry spare cells for it, and swap as needed.
 photo 10 F1 charging P1200169.jpg

Now onto the SC2. This is a very versatile charger, but I have to say it has not been the easiest to work with. Using the defaults is easy. Turn it on, and pop in your cells, the SC2 will charge them quickly, but it is when you want to change modes that it hasn’t been that easy. Because of this I’m not even going to attempt to explain so you definitely will want to refer to these instructions. I did find that some double clicking was required to enter manual mode. This is not mentioned in the instructions, so if it is not responding as you expect, try a double click.
Click on this image for the full size version. (Depending on your browser you might need to ‘right-click’ and ‘open in new tab/window’.)

Here is an IMR cell (from the TM03) charging on defaults. It is now displaying a full charge, as during charging the current lights show the charging current, and the voltage lights are used to display charging status with three LEDs. Once the three LEDs remain on steady, the cell is fully charged.
 photo 12 SC2 lights with cell P1220112.jpg

It is important to note that due to the high charging current, the SC2 will terminate a little early. You don’t quite get a completely full charge. You can always pop the mostly full cell into another charger for that final top-up but you don’t really need to.
This graph has three traces on it and two of them compare the SC2 and D4 chargers (both used to charge the TM03s’s cell).
The SC2’s slightly early termination can be seen with the earlier drop to low mode at around 1h 20m. Considering the vast reduction in charging time, this minor loss in overall output is well worth it.
 photo TM03 runtime.jpg

There is one major design flaw with the SC2 sent to me. The numbers on the display to show current and voltage are only printed on the plastic film on the display. When you unpack the charger you normally expect to remove a protective film from the display. As you do this, you find the numbers come off as well!
I had to put the film back on after finding this which is why there are some bubbles under the film.
My advice is to NOT remove the protective film (unless you have confirmed the number are now printed on the actual display.

As explained in the user manual, Slot 2 and the USB charging output contend with each other. If the cell in Slot 2 is charging the USB output is stopped. So you can charge a cell in Slot 1 and a USB device at the same time, but if using Slot 2, only once the cell is charged does the USB charging work.

Light Review: FOURSEVENS Quark Click QK2A-X (2xAA)

The original Quark models from FOURSEVENS redefined what a light could be, but with redesign forced upon them, FOURSEVENS had to re-imagine the Quark, and the Quark Click was born. This review is of the QK2A-X model (2AA)

 photo 05 Quark Click engraving P1240116.jpg

Taking a more detailed look:

FOURSEVENS packaging presents the Quark Click so you can get an all round view.
 photo 01 Quark Click boxed P1240094.jpg

Supplied with the QK2A-X is a holster, hand-grip, lanyard, spare O-rings and 2x AA Alkaline cells.
 photo 02 Quark Click unboxed P1240099.jpg

If you already know the Quark holsters, this is the same as all the others I have. The front/back are semi rigid with elasticated sides.
 photo 03 Quark Click holstered P1240107.jpg

On the back is a D-loop and fixed webbing loop.
 photo 04 Quark Click holstered P1240110.jpg

The Quark range have removable steel pocket clips.
 photo 06 Quark Click clip P1240122.jpg

As standard, the Quark Click comes with the ‘Tactical’ forward-clicky switch.
 photo 07 Quark Click rear P1240125.jpg

Being a ‘Tactical’ switch the button protrudes for easy access, so no tail-standing for this one.
 photo 08 Quark Click button P1240128.jpg

The FOURSEVENS logo is laser engraved on the head.
 photo 09 Quark Click engraving logo P1240129.jpg

At the base of the compact textured reflector is a XM-L2 LED.
 photo 10 Quark Click reflector P1240138.jpg

Thanks to the design including a location guide surrounding the LED, the LED is very well aligned with the reflector.
 photo 12 Quark Click LED P1240135.jpg

Taking the head off, and you can see the contacts inside it. These include physical reverse polarity protection.
 photo 11 Quark Click contacts P1240141.jpg

The threads are square and bare metal. They arrive well lubricated.
 photo 13 Quark Click threads P1240146.jpg

Inside the tailcap is a strong spring contact for the negative connection. Due to the use of bare metal threads, the Quark Click cannot be locked-out by unscrewing the tail-cap slightly – instead you must unscrew the head of the Quark Click half a turn.
 photo 14 Quark Click tail contacts P1240150.jpg

And here we have one of the Quarks’ historical features, its lego-ability (change the head, or battery tube, or switch). In this case, simply use a 1xAA long battery tube and this Quark can now use 1xAA or 1×14500 as well as the original 2xAA.
 photo 15 Quark Click 1AA P1240154.jpg

So this is the Quark Click QK2A-X next to 2xAA cells for size reference.

The same head and switch now on a 1xAA battery tube next to1xAA for size reference.
 photo 17 Quark Click size 1AA P1240162.jpg

Another feature of FOURSEVENS lights is the inclusion of the hand-grip. Not frequently talked about, this is a very useful accessory. Here it is fitted to the QK2A-X.
 photo 18 Quark Click strap P1240168.jpg

Slipping the hand-grip over your fingers positions the Quark like this.
 photo 19 Quark Click strap in hand P1240176.jpg

You position the hand-grip to wherever it is most comfortable for you. This is where I like it, not quite onto my knuckles.
 photo 20 Quark Click strap in hand P1240174.jpg

No need to hold onto the light as the hand-grip does this for you. You hand is free for other tasks (as long as they fit in with keeping the light where you need it).
 photo 21 Quark Click strap in hand P1240171.jpg

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and the wife won’t have one!

I’ve always like the Quark beam profile, and the latest Quark Click doesn’t disappoint. Good wide spill, and a hotspot giving good reach make this a great all rounder. If you study the beam close-up on a white wall, it can seem a bit unrefined, but step back and the beam is well diffused and very nice to use.
 photo 22 Quark Click indoor P1240746.jpg

Outdoors and the ultimate brightness of the Quark starts to show its limitations, but that hotspot does give you a reasonable range and the broad spill gives you a wide field of view, even if not the brightest. This is a 2xAA after all.
 photo 23 Quark Click outdoor P1240699.jpg

Modes and User Interface:

In its default configuration the Quark Click has two output modes Low and Max, but the model on test has been reprogrammed to include Moon, Low, Mid and Max/Burst (this customisation was requested as it is offered by FOURSEVENS as standard customisation).

For the default configuration (according to the manual):
To turn ON, either half-press the switch, or fully press it so it clicks.
To toggle between output modes turn the light ON, OFF, then ON again.
The last used mode is memorised if the Quark remains OFF for at least 5 seconds and is used next time you turn it ON.
To turn OFF, release the switch (if half-pressing it), or press it so it clicks and release.

For the customised Quark Click with Moon, Low, Mid, and Max:
To turn on, either half-press the switch, or fully press it so it clicks.
To toggle between output modes turn the light ON, OFF, then ON again – However, you have to cycle through Max, Low three to four times to access the additional modes, so Max, Low, Max, Low, Max, Low, Max, Moon, Low, Mid, Max, Moon……
Now we have another deviation from the standard interface when it comes to memory.
When using the Quark Click in the Max, Low mode selection (before reaching the additional modes) it does not memorise Low, it always starts on Max.
Only if you have selected a mode from the additional mode selection (Moon, Low, Mid, Max) is it memorised. Also it is only memorised if the Quark has been ON that mode for 5s and remains OFF for at least 5 seconds. Then once memorised, as long as there is not a full ON/OFF/ON cycle within 5s, it will remain on that mode.
If you memorise Max mode, the Quark Click returns to the Low/Max mode, and always gives you Max until you carry out the memorisation steps described above.
To turn OFF, release the switch (if half-pressing it), or press it so it clicks and release.

Batteries and output:

The Quark Click QK2A-X in its default configuration runs on 2x AA (Lithium, Alkaline or NiMh). With the additional 1xAA battery tube it will run on 1xAA (Lithium, Alkaline or NiMh) or 1x 14500.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

___________________________________________ ________________________________ ________________________________
Quark Click QK2A-X using specified cell I.S. measured ANSI output Lumens PWM frequency or Strobe frequency (Hz)
___________________________________________ ________________________________ ________________________________
Max/Burst – 2x AA Eneloop 296 0
Medium – 2x AA Eneloop 26 0
Low – 2x AA Eneloop 3 0
Moon – 2x AA Eneloop Below Threshold 0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 2500 lx @1m giving a beam range of 100 m.

There is no parasitic drain.

In this runtime graph are the output traces from using 2xAA Eneloop, and an AW protected 14500. Running the QK2A-X head on 3V or 4.2V doesn’t increase the maximum output. Both traces show the Burst mode where the first 30s of output are maximum, before dropping to approximately 50% of this. The output is then very well regulated right up to the point the cells become fully depleted.
With the 14500, there is an absolute cut-off when the protection kicks in (it goes OFF), but the 2xAA trace drops sharply, but doesn’t fully cut out.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The Quark Click QK2A-X in use

Anyone following my reviews will know that I consider the 2xAA form-factor one of the best. The QK2A-X has a slim battery tube with slightly larger head and tail-cap. making it very secure in the hand.

Even if you don’t really use pocket clips, it provides a very useful anti-roll function, so I’d rather leave it in place. As pocket clips go, it also has a generous capacity so is easy to use on thicker pocket edges like on some heavy cargo-pants.

With this one being a customised version, I was scratching my head a little when it wouldn’t memorise the low mode, but as explained in the UI section, you need to get to the additional modes before the memory function kicks in. It can seem a little fiddly as to memorise Moon mode you need to turn the Quark Click on and off 5 or 6 times watching the output to catch the Moon mode (miss it and you have to turn it on and off a further 4 times to get back to Moon). It works, but is not the slickest interface.

In most lights, lock-out is provided by undoing the tail-cap half a turn. It is slightly counter intuitive that the Quark uses the head to lock-out the Quark Click, but then again, this also means you can leave the tail-cap clicked on and then use the head to give you a twisty interface. Great for silent use, and twisting the head is very intuitive. Suddenly I’m liking that design feature much more.

With the interface being an ON/OFF/ON to switch modes, you can’t really use the momentary action for signaling. I’ve always preferred the immediacy of the forward-clicky tail-cap switch, so definitely prefer this to a reverse-clicky.

A little comment about the available levels and the Burst mode – Effectively, you have a combined Burst/High output as a single mode. After the initial 30s of Burst, the output drops to a very useful 150lm which is then maintained. Unfortunately it is not possible to directly enter the 150lm mode as it is always proceeded by the 300lm burst mode. When you look at the ANSI output levels this leaves a ‘hole’ in the available output levels as you have 296lm, then down to 26lm, then 3lm then Moon. Really that 150lm level is needed to fill the hole, and it is there, but you have to get through burst mode first.

Having Moon mode memorised, you will notice the FOURSEVENS pre-flash is present for this mode. This is a very quick flash of a level slightly brighter than Moon mode before it settles into the constant output. It has never caused me a problem and is more a characteristic than anything wrong. With the Moon mode being a true Current Controlled output it is far preferable to some PWM control of this level.

PWM – well I might have just mentioned it, but I’m happy to say there is none present in the Quark Click. None of the modes available in this sample exhibited PWM at any frequency.

A classic, game-changing, lego-able design, rebooted with a simple interface and one that can be operated as a clicky or a twisty.

Review Summary

_______________________________________________ _______________________________________________
Things I like What doesn’t work so well for me
_______________________________________________ _______________________________________________
Excellent All-Rounder beam. Mode memorisation a little laborious in this customised Quark.
Current Controlled output (no PWM). Tail-standing not possible with standard tail-cap.
Lego-able design compatible with all previous Quark models. 150lm output only available after 30s by first using the Burst Mode.
Optional AA and CR123 battery tubes.
Spacious/removable pocket clip provides anti-roll.
Wide input voltage range 0.9-4.2v.
Can be used as a Twisty or Clicky.

Light Review: NITECORE TM03 (Tiny Monster)

NITECORE have been expanding the Tiny Monster line and with the TM03 have shrunk the monster performance into a single 18650 size light. Now it is even easier to carry Tiny Monster performance with you in the form of the world’s most powerful 1x 18650 light.

 photo 00 TM03 feature P1210997.jpg

Taking a more detailed look:

Following the other TM series lights, the TM03 comes in a tough cardboard box.
 photo 01 TM03 boxed P1210968.jpg

The light is held in place with a strong closed cell foam.
 photo 02 TM03 box open P1210973.jpg

Along with the TM03, a holster, the instructions and a spare o-ring are provided.
 photo 03 TM03 box contents P1210979.jpg

Before we look at the TM03 in more detail, let’s look at the holster. Here it is with the TM03 inside.
 photo 04 TM03 holstered P1210983.jpg

You have the choice of D-loop, fixed loop, or Velcro loop.
 photo 05 TM03 holster loops P1210986.jpg

There is a blue plastic lens protector on the front when it arrives. You MUST remove this before trying the TM03 at all as it will melt and make a mess of the lens if you don’t.
 photo 06 TM03 protector P1210991.jpg

As with the NITECORE Precise series, the TM03 has a dual switch tail-cap. One is a forward clicky standard switch and the other is a metal paddle MODE switch.
 photo 07 TM03 switches P1220001.jpg

Supplied in the TM03 is a special IMR cell, clearly labelled ‘FOR TM03’. It is normal 18650 size, so this gives you and idea of the overall size of the TM03.
 photo 08 TM03 cell out P1220005.jpg

In the tailcap are the two normal contacts.
 photo 09 TM03 tailcap contacts P1220008.jpg

Mainly for heat-sinking, the TM03 has a heavy duty thick walled battery tube.
 photo 10 TM03 tube wall P1220011.jpg

Standard threads are used for the tail-cap.
 photo 11 TM03 threads P1220012.jpg

Back to the dedicated 18650 IMR cell. Notice the dual contacts at the front.
 photo 12 TM03 cell P1220018.jpg

Taking a closer look at the dual contacts on what would normally be the positive end of the cell.
 photo 13 TM03 positive P1220021.jpg

The negative terminal of the cell is standard.
 photo 14 TM03 negative P1220024.jpg

Peering inside the battery tube you can make out the positive contact as well as the secondary contacts surrounding it.
 photo 15 TM03 head contacts P1220028.jpg

Finish is to a high standard as is the engraving.
 photo 16 TM03 engraving P1220030.jpg

Despite the high output, the cooling fins are shallow.
 photo 17 TM03 fins P1220033.jpg

Here is the heart of this Tiny Monster, its monster XHP70 Quad die LED.
 photo 18 TM03 XHP70 LED close P1220045.jpg

The reflector is textured to give a smoother beam, but the reflector also has two profiles specifically controlling how much spill and hotspot the TM03 has.
 photo 19 TM03 XHP70 LED P1220053.jpg

Putting the TM03 next to a normal 18650 light, it is slightly bigger and heavier in build, but has performance that outshines the standard light by a long way.
 photo 20 TM03 size P1220127.jpg

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and the wife won’t have one!

With such high output, and indoor shot can easily be overblown, so this is not a representation of how bright the beam is, but the characteristics of the beam. Exposure has been adjusted to show the hotspot, spill, and outer spill. For such a large LED, there is quite a defined hotspot, and the spill is a medium width.
 photo 21 TM03 indoor beam P1230313.jpg

Then we go outdoors, and blast the full 2800lm , and this is the effect you get. The TM03 is bright, and it is very compact. Nice!
 photo 23 TM03 outdoor beam P1240710.jpg

Modes and User Interface:

The TM03 has four constant modes (Turbo, High, Mid and Low) and one flashing (Strobe) mode, controlled by a dual-switch tail-cap.

Basic operation is with the forward-clicky switch; half press for momentary access to the last used constant mode, and fully press and click to turn the TM03 ON to the last used constant mode. (Release or click again to switch off).

When ON, pressing the MODE switch cycles through the output modes – Low, Mid, High, Turbo, Low etc.

The TM03 allows you to set up the direct access operation of the MODE switch in two different modes – Suppressing Light, or STROBE READY.

To swap between these two modes:
Switch the TM03 OFF
Remove and replace the battery.
Within 60s of replacing the battery tighten the tail-cap while pressing and holding the MODE switch.
The TM03 will then flash once to indicate Suppressing Light, and two for STROBE READY.

In Suppressing Light mode:
Direct access to Turbo – in any mode including OFF, press and hold the MODE switch. Release to return to previous output.
Quick access to Strobe – in any mode including OFF, press the MODE switch twice in quick succession. Press again to return to previous output.

In STROBE READY mode:
Direct access to Strobe – in any mode including OFF, press and hold the MODE switch. Release to return to previous output.
Quick access to Turbo – in any mode including OFF, press the MODE switch twice in quick succession. Press again to return to previous output.

When inserting the battery, a red light in the tail-cap flashes to indicate battery power. Three blinks for above 50%, two blinks for below 50% and one blink for less than 10%.

Batteries and output:

The TM03 runs on a supplied proprietary IMR call with dual contacts on one end, but will also run at a severely reduced output on a normal 18650.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

___________________________________________ ________________________________ ________________________________
NITECORE TM03 using specified cell I.S. measured ANSI output Lumens PWM frequency or Strobe frequency (Hz)
___________________________________________ ________________________________ ________________________________
Turbo – TM03 IMR 2804 0
High – TM03 IMR 1501 0
Medium – TM03 IMR 632 0
Low – TM03 IMR 34 0
Max – ‘Normal’ AW IMR 259 0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 21300 lx @1m giving a beam range of 292 m.

There is parasitic drain and due to the dual contact at the head of the light there is drain at the head, and drain at the tailcap. When using the TM03’s IMR cell, the drain was 1.7mA at the head and 15uA at the tailcap. Taking the worst of these as the only significant value, it is the head drain that is relevant as it will take only 76 days to drain the cell.

NOTE: The use of the AW IMR cell for the ‘normal’ 18650 test was to prove that the throttling of output was not due to a bad cell. The TM03 is drastically throttled when not using the supplied cell and this is no reflection on the AW cell.

This graph has three traces on it to show a couple of specific aspects, including comparing a couple of NITECORE chargers, the SC2 and D4 (both used to charge the TM03s’s cell), and also showing the characteristics depending on if you start in Turbo or High.
The SC2 is a rapid charger, well suited to IMR cells. Due to charging at a higher current, it also tends to terminate earlier. This can be seen with the earlier drop to low mode at around 1h 20m. Considering the vast reduction in charging time, this minor loss in overall output is well worth it.
Then look at the overall characteristics when starting on Turbo where after the initial 2800lm burst, the output drops right down to the 630lm Mid level output, and then continues on this until the cell is depleted.
When starting on High, the output remains on High until the cell can no longer maintain the output and starts to drop in stages, gradually reducing at 20m all the way through to 1h from turn on.
Effectively if you want more light for longer, either stay on High, or you’ll have to switch it OFF and ON again to get Turbo (as long as it is not too hot), and expect not to have much runtime.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The TM03 in use

Normally I don’t like to start with a negative, but the TM03 does have one issue, and that is particularly with the Suppression Mode. I have found that when closing the holster flap over the TM03’s tail-cap, it is easy to press (or more dangerously – nearly press) the MODE switch enough to activate direct access Turbo. This means that inside the holster the TM03 bursts into life with all 2800lm. It gets hot VERY fast. Now I also said ‘more dangerously – nearly press’, and the reason it is more dangerous, is that the TM03 is now on a hair trigger needing only a tiny pressure on the holster to bring on the Turbo output. I was putting the TM03 into a drawer and as it nestled against some other items Turbo came on. Luckily I noticed, but I could easily have closed that drawer – for the last time.
So my first comment is that if using the holster you need to undo the tail-cap a half turn (a quarter is not enough) to lock-out the TM03.

Now onto the good stuff. This is a very bright light. Even these days when people are used to high output lights, the TM03 still surprises with its compact size. It is not much bigger than standard 1x 18650 lights, but is a lot more powerful. The heavy build is reassuring and is certainly needed for heat-sinking. I never had the sense the TM03 was getting too hot.

My own views on tactical lighting requirements gathered from various members of the armed services and law enforcement are that Strobe is not the preferred output, but very bright is. The TM03 does VERY bright, very well.

Of course with the fundamental law of portable lighting that you can only have two of the three factors – Bright, Small, Long Runtime, the TM03 looses out in runtime. Mainly this is because if you have the TM03 on you, why would you bother with the Low mode? You will be enjoying all those lumens, using bursts of Turbo, and all too soon it does start to struggle. Not the fault of the TM03, but just a factor to be aware of – this is a Tiny Monster after all.

It was worth the extra effort required to check the parasitic drain at the head, as this explains why after only short periods of storage, the runtime is even more reduced. This level of drain is bad. It is easy to pop a light in a drawer for three months at a time, and in that time the TM03 will be dead. Even if you undo the tail-cap slightly, this doesn’t stop the double pole in the head making contact and draining the cell, you need to remove the cell completely.

With regard to using other 18650 cells, NITECORE have severely hobbled the output on the TM03 when not using its dedicated double pole IMR. The maximum output I managed to get was around 250lm. It does mean that you know you can still have enough light to see by if you carry a normal 18650 as a spare, but once that dedicated IMR is depleted, you need to recharge before you get the TM performance again. At least you know it will work as a backup, and with such extreme performance it is sensible to protect the light and the user from ‘unknown’ cells.

If you want a pocket rocket, the TM03 will not disappoint, and brings custom level performance to a production light.

Review Summary

_______________________________________________ _______________________________________________
Things I like What doesn’t work so well for me
_______________________________________________ _______________________________________________
2800lm on a single 18650!! Direct access via the MODE switch too easily activated by the holster flap.
Solid build. High Parasitic Drain.
Direct access to TURBO. Uses a proprietary cell for full performance.
Sturdy holster provided.
Supplied with cell so you only need a charger.

EDC Gear Review: Nite Ize S-Biner with SlideLock, MicroLock plus GearLine

There are some things that are so useful you can’t really image life without them. Nite Ize’s S-Biners are one of those designs that have simply integrated themselves into so many of my every-day activities I’d be lost without them. For some these will need no introduction, but if you haven’t used them before it is very likely the S-Biner is going to find a way into your selection of gear.

 photo 01 NiteIze S-Biner Group boxed P1210803.jpg

A few more details:

In the introduction image are all the versions of the S-Biner featuring in this review, which include the S-Biner – #10, S-Biner – #8, S-Biner SlideLock, S-Biner MicroLock, S-Biner® MicroLock® – Polycarbonate, KeyRack Locker® – Polycarbonate S-Biner® MicroLocks® and GearLine Organization System 4FT.

Moving forward I’m breaking this down into three groups, the larger S-Biners, micro S-Biners and the Gearline system.

Starting with the BIG S-Biner – #10 and S-Biner – #8, plus the S-Biner SlideLock.
 photo 02 NiteIze S-Biner Group1 P1210807.jpg

Here are the first set of S-Biners
 photo 04 NiteIze S-Biner Group1 unboxed P1210814.jpg

The packs say ‘BIG’, and big they are. These are the two largest S-Biner models. They only come in plastic versions and give you the option of a super-sized clip.
 photo 05 NiteIze S-Biner large in hand P1210818.jpg

Of course the SlideLock S-Biners are much more normal in size for clipping keys and anything else to bags, belts etc.
 photo 06 NiteIze S-Biner small in hand P1210829.jpg

With the SlideLock, you can see the black plastic slider on each gate. Here the top one is locked and the other unlocked.

The instructions for the SlideLock are very clear, but you don’t need these, it is obvious how simply and easily they work.
 photo 03 NiteIze S-Biner lock P1210813.jpg

Looking in closer at the slider, it is shaped so that it won’t easily fall off the gate bar.
 photo 12 NiteIze S-Biner slider P1210858.jpg

In the locked position the gate is positively held closed so the S-Biner won’t get twisted off and become lost.
 photo 13 NiteIze S-Biner slide locked P1210865.jpg

Next up are the real key-ring sized S-Biner models the Micro-versions. In this case these all feature the micro-lock design.
 photo 07 NiteIze S-Biner Group2 P1210830.jpg

We have the standard metal S-Biner MicroLock, then the ultra-light Polycarbonate S-Biner® MicroLock®, and lastly the KeyRack Locker® – Polycarbonate S-Biner® MicroLocks® where the keyrack is metal and the S-Biners are Polycarbonate.
 photo 08 NiteIze S-Biner Group2 unboxed P1210841.jpg

The MicroLock is a stroke of genius. With the smaller clips you are often carrying vital objects like keys. Previously the smallest S-Biners were pretty secure, but with the MicroLock you remove all doubt.
In the middle is a small plastic arm which rotates. When aligned lengthways, the gates are unlocked, but when turned cross-ways and clicked into the locked position, both gates are locked shut. Sitting on these or otherwise giving them a hard time won’t shift those gates – believe me, I’ve given them a run for their money and the lock has not let me down.
 photo 09 NiteIze S-Biner micro close P1210846.jpg

Same hand (I take an XL size glove by-the-way) and these are as small as they can be, but still easy to use.
 photo 10 NiteIze S-Biner Group2 in hand P1210852.jpg

Lastly in this review is a logical extension of the usefulness of the S-Biner, and that is the GearLine. This is the GearLine Organization System 4FT.
 photo 15 NiteIze S-Biner gearline P1210873.jpg

This system contains 5 x #2 and 5 x #4 Plastic S-Biners on a special webbing strap with 2 x 12″ Gear Ties, one on each end.
 photo 16 NiteIze S-Biner gearline unboxed P1210880.jpg

The Gear Tie fresh out of the box.
 photo 17 NiteIze S-Biner gearline end P1210883.jpg

Along the webbing strap are a series of loops formed by the double layer of webbing.
 photo 18 NiteIze S-Biner gearline loop P1210887.jpg

Two sizes of plastic S-Biners are used (#2 and #4).

Quickly comparing the S-Biners in the GearLine system and the three sizes of SlideLock S-Biners.
 photo 20 NiteIze S-Biner gearline comparing P1210894.jpg

Those Gear Ties just untwist and are a stronger version of twisty-ties.
 photo 21 NiteIze S-Biner gearline twist P1210900.jpg

What it is like to use?

Anyone leading an active life and who uses a variety of gear will need and use clips and karabiners of various types. The biggest revelation of the S-Biner design over karabiners is the double-gate. This keeps the item you are carrying secured separately to whatever you are attaching it to. A simple thing, but it means that when you open one gate or the other, you are either releasing the item, or taking the S-Biner off from the attachment point.
With a standard karabiner when you open the gate both the item carried and the fixing point can be released; not always what you want. Intended as true load-bearing devices, the karabiner is usually larger and heavier than you might want. Not only does the S-Biner take a karabiner to a more useful layout, but it is also not as big and heavy, as it is not intended to carry the weight of a person.

When preparing this review I wondered how I would show the extent to which I use these, but while standing there in my photo studio, I just patted myself down and pulled all these out of my pockets/belt. We’ll take these one at a time in a moment, but you see how integrated these are.
 photo 24 NiteIze S-Biner in use P1250369.jpg

So the biggest here is a torch/flashlight pouch which is clipped onto my belt or belt loop, or onto my backpack.
 photo 25 NiteIze S-Biner pouch P1250374.jpg

Mainly a marker, this Glo-Toob is left to flap about (normally on my backpack) so needs the extra security of a locking S-Biner.
 photo 26 NiteIze S-Biner glo-toob P1250377.jpg

A couple of work related items which need to go from one bag to another and the KeyRack holds a SecurID tag and a USB flash drive. There is normally another flash drive on here but it has been lent at this time.
 photo 27 NiteIze S-Biner serureid P1250381.jpg

On this kevlar cord retracting key ring is a MicroLock S-Biner that has been particularly heavily tested. Sat on, caught in doors and accidentally hooked onto this and that, the door entry tag has never come loose.
 photo 28 NiteIze S-Biner door tag P1250386.jpg

Then my keys. Pretty heavily loaded with more non-key items in the wrap, but outside the widgy pry-bar and a TUBE light are held securely with the plastic MicroLocks.
 photo 29 NiteIze S-Biner widgy P1250389.jpg

So that GearLine, where is it? When I go camping I do use this inside the tent, but it also has an every-day use, which for me is in the boot (trunk) of the car. Fixed between two headrest posts, the GearLine gives me lots of fixing points to stop various items moving round. Most often I use this to keep shopping bags from rolling around and emptying themselves, but other things go on and off the S-Biners.
 photo 23 NiteIze S-Biner gearline car P1250346.jpg

The only aspect of the S-Biner that occasionally causes a problem is that there is a groove in each hook where the gate bar sits when it is closed, and when taking the S-Biner out of a tight-fitting loop, sometimes this groove catches and makes it difficult to remove. Other clip designs also have this but the S-Biners somehow seem to catch more than most. I certainly forgive the design this minor flaw as overall the S-Biner makes the karabiner a practical true ever-day carry item and I would not be without them.

The BIG S-Biners also bring this practicality to a much larger scale. I carry the #10 S-Biner as a backpack hook and use it to hang the bag on tree limbs, rails and any other suitable hanging point up to the thickness of your wrist.

You have a choice of size, weights (plastic or metal), materials which are either stronger or anti-scratch as well as two types of lock.

Review Summary

The views expressed in this summary table are from the point of view of the reviewer’s personal use. I am not a member of the armed forces and cannot comment on its use beyond a cutting tool or field/hunting knife.

Something that might be a ‘pro’ for one user can be a ‘con’ for another, so the comments are categorised based on my requirements. You should consider all points and if they could be beneficial to you.

EDC Gear Review: NITECORE Utility and Daily Pouches – NUP10/20 and NDP10/20

NITECORE have gone beyond just portable lighting and have started designing products for EDC and daily carry. We now have the NUP10/20 Utility Pouch and the NPD10/20 Daily Pouch which give you plenty of carry options for all those essential bits of EDC gear.

 photo 00 NC Pouches intro P1230459.jpg

The details:

On test in this review are two of the four versions of these pouches, the NUP20 and NDP10. They arrive (like most bags) in a cellophane over-wrap.
 photo 01 NC Pouches wrapped P1230428.jpg

Starting with the NDP10, firstly let’s just cover the naming convention for these pouches. The NDP part means that this is the NITECORE Daily Pouch, and the NDP is either the 10 or 20 depending on the front panel. If this is 10, it has a ‘Hypalon’ Synthetic Rubber panel, or if 20, it has a ‘Velveteen’ Synthetic fabric front panel.
 photo 03 NC Pouches NPD10 P1230468.jpg

So this NDP10 pouch is the larger ‘Daily Pouch’ and it has the ‘Hypalon’ front panel.
 photo 05 NC Pouches NPD10 zip pulls P1230481.jpg

In keeping with the stealth appearance of the pouches, the rubber NITECORE logo has none of the usual yellow colouring.
 photo 06 NC Pouches NPD10 brand P1230484.jpg

If you haven’t come across Hypalon before, it is a synthetic rubber made of chlorinated and sulphonated polyethylene, noted for its resistance to chemicals, temperature extremes, and ultraviolet light.
 photo 07 NC Pouches NPD10 hypalon P1230487.jpg

A detail of the Hypalon’s surface and cut-outs.
 photo 08 NC Pouches NPD10 hypalon P1230489.jpg

Access to the comparments is via the zip closures, and NITECORE have made these zips very easy, with large zip-pulls having a semi-circular moulded loop.
 photo 09 NC Pouches NPD10 zip pulls P1230492.jpg

On this larger Daily Pouch, there is a small hook and loop patch-panel for personalising your pouch. On the NPD20 you can fix patches to the entire front panel, but the Hypalon prevents this on the NPD10.
 photo 10 NC Pouches NPD10 patch panel P1230495.jpg

There is a padded carry handle on the top of the pouch so it can be held like a small bag.
 photo 11 NC Pouches NPD10 handle P1230502.jpg

It also comes with a shoulder strap.
 photo 12 NC Pouches NPD10 plus strap P1230505.jpg

The shoulder strap clips onto D-rings either side of the handle.
 photo 13 NC Pouches NPD10 strap clip P1230509.jpg

On the back there is a PALS webbing attachment which is compatible with PALS/MOLLE systems.
 photo 04 NC Pouches NPD10 pals P1230471.jpg

Supplied with the NPD10 are two PALS connection strips which have a Velcro closure.
 photo 14 NC Pouches NPD10 PALS P1230514.jpg

Opening the main compartment, there is a pocket fixed to the front with an elastic organiser strip, and the rear of the main compartment has a full hook and loop surface for additional flexibility, plus another elastic organiser strip.
As the zips run all the way from one side to the other and have double zip-pulls, the access to these pouches is ambidextrous.
 photo 15 NC Pouches NPD10 main P1230518.jpg

The hook and loop organiser surface in the main compartment.
 photo 17 NC Pouches NPD10 main inside P1230534.jpg

Inside the front compartment, there is even more organisation for small items. Two elastic strips, a front pocket and a clip/D-ring fixing point for keys etc.
 photo 16 NC Pouches NPD10 front P1230527.jpg

Now we switch to the smaller NUP20. NITECORE Utility Pouch with ‘Velveteen’ Synthetic fabric front panel.
 photo 18 NC Pouches NUP20 P1230540.jpg

Again, in keeping with the stealth appearance of the pouches, the rubber NITECORE logo has none of the usual yellow colouring.
 photo 19 NC Pouches NUP20 logo P1230543.jpg

A closer look at the plush Velveteen Synthetic fabric front panel.
 photo 20 NC Pouches NUP20 patch front P1230547.jpg

As on all of the NITECORE pouches there are large zip-pulls for easy access.
 photo 21 NC Pouches NUP20 zip pulls P1230551.jpg

There is a padded carry handle on the top of the pouch so it can be carried like a small bag.
 photo 22 NC Pouches NUP20 handle P1230556.jpg

The Utility Pouch also has a shoulder strap.
 photo 23 NC Pouches NUP20 strap P1230560.jpg

This too clips onto D-rings each side of the handle.
 photo 24 NC Pouches NUP20 strap clip P1230561.jpg

The strap is a generous size so should accommodate wearing it over even large coats.
 photo 25 NC Pouches NUP20 strap fitted P1230566.jpg

On the back of the NUP20 is the same PALS attachment system as used on the Daily pouches.
 photo 26 NC Pouches NUP20 PALS P1230570.jpg

As before the PALS connection strips have a Velcro closure.
 photo 27 NC Pouches NUP20 PALS P1230574.jpg

In the main compartment, the layout is the same as with the Daily pouch, but the compartment is just smaller.
 photo 28 NC Pouches NUP20 main P1230578.jpg

It too has the hook and loop rear panel inside the main compartment.
 photo 29 NC Pouches NUP20 main detail P1230580.jpg

Using the same configuration as the NDP pouches the NUP 20 has two elastic strips, a front pocket and a clip/D-ring fixing point for keys etc. inside the front compartment.
 photo 30 NC Pouches NUP20 front P1230589.jpg

A closer look at the clip/D-ring.
 photo 31 NC Pouches NUP20 front clip P1230591.jpg

A very brief aside here looking at a couple of other NITECORE pouches/holsters, the NCP30, as one of these will appear in the next section.
 photo 32 NC Pouches NCP30 P1230597.jpg

What are they like to use?

The way you choose to carry your EDC gear is as personal as your choice of the gear itself. What you are doing and where you are going also completely changes the requirements of your carry system, so you will need a few options to suit these differing requirements. For any scenario, no one bag/pouch/system will suit everyone, and the way you fill that carrying system will also be unique. So really the best thing you can have are options, and the NITECORE pouches give you options.

Taking the larger Daily Pouch the NDP10, here I’ve shown one example of a set of gear I’ve been carrying.
 photo 33 NC Pouches NPD10 contents P1230765.jpg

This is a snapshot of a set of gear that changes depending on, well, the day. This is not an over-stuffed pouch as I don’t like ramming things to full capacity as it just makes it more difficult to find things, but the list here includes:

A fire-resistant Buff
Mini screwdriver set
3mm cord hank
Gorilla tape mini roll
Jaffa Gaffa tape mini roll
2mm cord hank
CountyComm Pico Grappling hook
NITECORE F1 charger/powerbank
NITECORE NL188 3100mAh 18650 cell
NITECORE USB cable
NITECORE P20UV
Mini adjustable spanner
Screwpop Magnetic Screwdriver
Chris Reeve Knives Large Inkosi
Fällkniven Flipstone Sharpener
NITECORE NWS20 Titanium Whistle
NITECORE NTP10 Titanium Pen
Sharpie Mini Marker
NITECORE SENS AA
Uncle Bill’s Sliver Gripper Tweezers
Burketek Pocket Wrench II
Gerber Bear Girls compact multi-tool
A ‘peak_wanderer’ Unseen Ring Spinner

Not too shabby, and prepared for the odd eventuality. Remember this was not crammed full, but was accessible.

Like this I was carrying the NDP10 inside a larger bag, using at as an organiser, and also separately with the shoulder strap. I found it a bit dense/heavy for PALS/MOLLE mounting.

As a bit of an aside, to free up a bit of space inside and to make access to the bigger light easier I decided to use the PALS feature on the front to fit the NCP30 pouch onto the NDP10.
 photo 35 NC Pouches NPD10 with pouch P1230791.jpg

From this angle you can see the PALS connection strap woven through the PALS panel.
 photo 36 NC Pouches NPD10 with pouch P1230793.jpg

The NCP30 has an elasticated body that holds onto the light so you don’t need to have a top flap covering it.
 photo 37 NC Pouches NPD10 with pouch open P1230799.jpg

If you are concerned though, you can bring a retaining flap out of the NCP30 to fully secure the light.
 photo 38 NC Pouches NPD10 with pouch closed P1230804.jpg

So, these NITECORE pouches give you options for organisation and carry of those essential EDC bits and pieces. In-bag carry, direct carry, on-bag carry and shoulder-strap carry options for sensible sized pouches that are small enough to be convenient and large enough to be useful.

Light Review: Nitecore’s Explosion Proof EF1

With the EF1, NITECORE have confidently entered the market for hazardous environment equipment, with a light which can be used in the petroleum exploration, petrochemical and chemical industries, as it is rated as a Type II non-mine explosion-proof electrical appliance.

 photo 00 EF1 Feature P1200195.jpg

Taking a more detailed look:

The EF1 arrives in a box like the ones used for the TM series.
 photo 01 EF1 boxed P1200173.jpg

Closed cell foam is used as the liner.
 photo 02 EF1 box open P1200177.jpg

With the EF1 you get a holster, lanyard, spare o-rings and the instructions.
 photo 03 EF1 box contents P1200185.jpg

The EF1 in its holster.
 photo 04 EF1 holster P1200188.jpg

On the back it has a fixed loop, a D-loop and a Velcro closed loop.
 photo 05 EF1 holster loops P1200191.jpg

It is a chunky light, but that is due to its heavy build for the Explosion Proof rating.
 photo 06 EF1 angle P1200197.jpg

The lens is very thick making it look like a dive light.
 photo 07 EF1 lens P1200203.jpg

On the side it proudly states its explosion proof status.
 photo 08 EF1 engraving P1200205.jpg

There are a couple of exposed screws on the head that seem to hold parts of the magnetic switch together.
 photo 09 EF1 screw P1200207.jpg

The switch is a rotating/sliding switch with four positions.
 photo 10 EF1 switch P1200210.jpg

It is difficult to really show how thick this lens is, but it is thick – 10mm thick.
 photo 11 EF1 lens P1200220.jpg

A view from the tail-cap end.
 photo 12 EF1 tail view P1200227.jpg

Inside the tail-cap is a spring and ring terminal.
 photo 13 EF1 tail contacts P1200235.jpg

That is one thick battery tube with a minimum thickness of 3mm.
 photo 14 EF1 battery tube P1200237.jpg

A long section of well lubricated standard threads are used for the tail-cap. They are fully anodised, so you can physically lock out the EF1 by unscrewing the tail-cap slightly.
 photo 15 EF1 battery threads P1200245.jpg

With a battery being inserted you see how thick that battery tube is.
 photo 16 EF1 battery insert P1200248.jpg

Peering deep into the battery tube for a view of the positive contact.
 photo 17 EF1 head contacts P1200256.jpg

The XM-L2 U3 LED sits in a smooth reflector.
 photo 18 EF1 LED P1200261.jpg

It is a relatively deep reflector to focus the beam.
 photo 18 EF1 reflector P1200264.jpg

Next to an 18650 cell you can see the heavy build of this light.
 photo 19 EF1 size P1200286.jpg

Slightly surprisingly, the head does unscrew giving access to the reflector and LED. This may be to provide access to the o-ring to allow it to be inspected.

 photo 21 EF1 head threads P1200291.jpg

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and the wife won’t have one!

Starting off indoors, the EF1’s beam is narrow overall. There is a relatively average sized hotspot, but only a very narrow spill around this. This appears much more suited to inspection duties than general lighting for getting around.
 photo 23 EF1 indoor beam P1230323.jpg

Giving it some more range outdoors and that narrow spill is still an obvious characteristic.
 photo 28 EF1 outdoor beam P1240708.jpg

Modes and User Interface:

Nitecore have kept the interface of the EF1 very simply. There is a four position sliding switch, OFF (0), Low (1), Medium (2) and High (3).

Simply slide the switch to the position you want. There is nothing more to it.

Batteries and output:

The EF1 runs on either 1x 18650 or 2x CR123.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

___________________________________________ ________________________________ ________________________________
EF1 using specified cell I.S. measured ANSI output Lumens PWM frequency or Strobe frequency (Hz)
___________________________________________ ________________________________ ________________________________
High – NL189 729 0
Medium – NL189 341 100
Low – NL189 5 217

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 13900 lx @1m giving a beam range of 236m.

There is parasitic drain which varies between 2.68 and 1.2 mA. When using a 3100mAh 18650 it will take 48-108 days to drain the cell. This is very bad for a standby light.

Initially I was testing the EF1 with an Xtar 3100mAh 18650, but the output figures were not up to specification. Subsequently I re-ran these tests with a Nitecore NL189. With the NL189 the ANSI output was higher, but as you can see the runtime was overall lower. Output is not regulated and drops off during the entire run. In the environments in which you would use this light, you definitely don’t want a sudden drop in output at the wrong time, so this is a better runtime profile to have.
 photo EF1 runtime plus Xtar.jpg

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The EF1 in use

Before we get any further we must clarify what ‘Explosion proof’ actually means. Firstly, it does not mean you can drop a bomb on it! Instead it relates to the world of hazardous environment equipment, for which there are many different and very specific standards for the various classifications of hazard. The safest equipment are ‘Intrinsically Safe’ devices which are intrinsically incapable of igniting hazardous atmospheres even if destroyed, as no component within them can achieve ignition, including the cells. Then there are the ‘Explosion-Proof’ ratings where the device does indeed contain enough energy to ignite explosive gasses, but critically, should the device have been opened in that hazardous atmosphere and contain an explosive mixture which can be ignited, if there is a small explosion within the device, that explosion is completely contained and cannot propagate into the surrounding atmosphere. The ‘Explosion Proof’ rating is protection from internal explosions.

Now we have got that clear, a direct consequence of the explosion proof rating is that the build is very heavy. Putting the EF1 next to a two cell light, the P36 shows how even though it is a single 18650 light, it really has presence. We are looking at one very tough light.
 photo 22 EF1 size p36 P1200296.jpg

With it being a very solid build, and having a sliding switch, actually the EF1 could also be very suited to diving use. While carrying out my Dive Knives 2016 – Mega Test Review I also took the EF1 with me, but wasn’t able to get any in-use shots. It was ceratinly taken to depths greater than the 1.5m specified, but not more than 10m where I was diving.
One thing I did put the EF1 through was the dive knife corrosion testing (details in the Dive Knives 2016 – Mega Test Review) and this is what happened to the EF1.
Taking in the overall view, the most obvious sign is a small white patch on the handle.
 photo 24 EF1 corrosion P1230810.jpg

Going in closer we can see this is a patch of aluminium corrosion from the salt water exposure. There must have been a small flaw in the anodising for this to have happened.
 photo 25 EF1 corrosion P1230823.jpg

Just next to one screw on the head was a rainbow like colouring on the anodising looking like an oil film. It was perfectly dry and free of oil, and this was only visible after the corrosion test.
 photo 26 EF1 corrosion P1230817.jpg

The last visible effect was that the grease around the sliding switch turned a dark brown/black colour, so was not an inert grease.
 photo 27 EF1 corrosion P1230820.jpg

There were no issues with the EF1 following this intensive corrosion test, and it is still functioning perfectly.

Though we tend to prefer smaller and easier to carry lights, there is a certain satisfaction to carrying the tank-like EF1. Its weight is comforting and there is nothing fragile about it. The slider switch is positive and simple to use and needs no explanation. There is a noticeable delay in the switch response, most notable when switching the EF1 on from OFF. It is probably only 0.3s or thereabouts, but you move the switch, then the EF1 turns on after that brief pause. The same when changing levels.

For my own use, the biggest issue is the mode spacing. It has a useful 5lm Low mode, but then jumps to 341lm. It definitely could have done with something around 80lm-100lm mark instead of jumping right up to 340lm. When the 5lm is not enough, that jump can be blinding.

Not working in a hazardous environment myself, I can’t say if the beam profile is a good fit for this type of use. It certainly seems to be an inspection type of beam rather than one for general use and getting about. I found it too narrow for navigating on rough ground as the hotspot was giving peripheral blindness when shining it at the ground. It is fine for longer distances, just not good closer up.

For the domestic user, there is the attraction of the Explosion Proof rating particularly in case of gas leaks. Personally I have several gas-safe lights including intrinsically safe lights. Those intrinsically safe lights however are all AA Alkaline powered, so the EF1 with its Li-ion power means the output is much higher, and I would consider it totally safe to use in a domestic gas leak situation. Some users would argue that any waterproof light will be safe to use, but this is wrong. If you change the battery and the explosive atmosphere gets inside the light, turning it on could create an explosion that would break out of a normal waterproof light. It would have been fine if you hadn’t opened it, but you did. With the EF1 this would not matter, as if this internal explosion did occur, the EF1 can withstand it – I know what I’d rather be holding.

Knife Review: Chris Reeve Knives Large Inkosi

The original Inkosi was launched at Blade Show 2016, and was designed to include improvements to Chris Reeve’s already tried and tested (and industry changing) Sebenza models. Never one to stand still, Chris knew he could improve on his original design with certain key changes to the pivot, bearing, frame and lock. Rather than apply all these changes to the established formula of the Sebenza models, a new line was created to allow these features to be incorporated into the most advanced Chris Reeve folding knife yet. With a trend to smaller more pocketable models, the first Inkosi was created as a compact folding knife, but demand has been strong for a larger version of this knife, and here it is. The Large Inkosi now replaces the Sebenza 25.

The Blade and Handle Geometry:

Most knife specifications have a basic description of the blade geometry, but in this section I will be taking a more detailed look at geometry and balance.
 photo 56 L Inkosi grind measure P1200597.jpg

Using a set of gauges and precision measuring equipment including a Vernier protractor, callipers, fixed radius gauges and the unique Arc Master adjustable radius gauge (the one that looks like a crossbow).
 photo Knife measuring P1180483.jpg

These measurements have been tabulated and are presented along with a few reference blades (8″ Chef’s Knife, 5.5″ Santoku and the popular Fällkniven F1).

Key aspects such as the primary bevel angle, grind type, blade depth, blade thickness, length, weight are detailed, along with balance information.
 photo 58 L Inkosi grind angle P1200604.jpg

The ‘Balance relative to the front of the handle’ tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The ‘Balance relative to the centre of the handle’ indicates how close to a ‘neutral balance’ the knife has in the hand.
 photo 53 L Inkosi balance P1200569.jpg

In the case of full convex grinds the approximate centre of the grind is used for the primary bevel angle estimate.

The blade is made from S35VN steel at 59-60RC.

Explained by the Maker:

The reasons for certain design choices may not be clear when simply looking at an object, so this section is intended to give an insight into the thinking behind a design by speaking to the designer themselves.

Unfortunately I can’t always get time with the designer so will use this section to include relevant information about the knife and its designer.

The history of this review goes back to before the release of the Large Inkosi and to IWA 2016 where I was fortunate to be able to speak to Tim Reeve about the Inkosi. It was during this discussion that Tim told me the Large Inkosi was in development. My own preference is for a larger lock knife, so I couldn’t wait for the Large Inkosi to be released.

Tim talked me through the design improvements introduced with the Inkosi which actually include all the major parts, the pivot, bearing, frame and lock.

There is one feature of the Large Inkosi which is not new, but is worthy of mentioning as it is now a CRK design feature that was introduced in the Sebenza 25, the ‘Large Hollow Grind’. The shape of this grind is itself not new, having been common when you go back to older production methods. Before grinding wheels were mass produced in smaller sizes, blades were ground on much larger wheels than are generally used today. Modern grinders tend to have smaller diameter wheels, so hollow grinds have become deeper and more pronounced. This has given the hollow grind its very sharp thin edge, but a blade which hangs up on the shoulders of the hollow grind when cutting deeply. With the growing popularity of the full flat grind, thanks to its smooth cutting action, the modern hollow grind has been losing traction.

That said, both hollow and flat grinds have their place and individual benefits. When looking to make the folding knife as useful as possible, CRK didn’t just follow the trend of going one way or the other, but instead wanted a blade that blends the best of hollow and flat grinds. Using a much larger wheel to grind the blade results in a ‘Large Hollow Grind’ which is almost flat, but slightly hollowed. This stops the blade hanging like a hollow grind would, and allows for more sharpening cycles before the blade edge starts to thicken up. This image (borrowed from CRK) shows how the ‘Large Hollow Grind’ fits between flat and hollow grinds.

 photo largehollowgrindweb.jpg

Here you can see the slight dip of the grind with a flat edge lying across it.
 photo 54 L Inkosi grind P1200578.jpg

In the previous section ‘The Blade and Handle Geometry:’ you could see the size of the hollow grind being measured with the Arc Master radius gauge. This is a closer look at the measuring arc sitting in the hollow grind with the gauge set at 12″ radius, so a 24″ wheel has been used for this grind.
 photo 57 L Inkosi grind measure close P1200593.jpg

This next image is a big hit of detail as it shows the Large Inkosi almost fully disassembled. For the moment there are two specific details I’d like to focus on and they are the large pivot and shaped phosphor bronze washers.
In earlier designs, the size of the washer on the lock side was limited by the end of the lock bar and if the washer were to have a cut out, it might rotate and then interfere with the lock. In turn, the size of the washer limited the size of the blade pivot, as if the pivot were made larger, the washer would become smaller and provide less support to the blade.
Taking the washer to the maximum size allowed by the handles means it can then be shaped to locate on the blade stop pin and not rotate into the way of the lock bar. It also allows the washers to be the same both sides bringing equal stability to each side of the blade.
Now that the washer has broken free of the earlier limits, it is possible to increase the size of the blade pivot and so increase the strength of this joint.
However, all this extra contact area increases friction with the blade tang, making the knife more difficult to open, so large perforations have been added to the washers to reduce friction without weakening the support of the blade. The perforations also store more lubricant and offer space for small particles of dirt to move away from the contact surfaces of the blade and washer, helping to prevent blade from stiffening up over time.
 photo 14 InkosiWasher Step all parts plus new P1230240.jpg

Only with the knife fully disassembled can you get a really good look at another design feature, the ceramic ball used in the lock.
Other integral locks use either the titanium itself or an insert of hardened steel for the locking surface. Looking to improve on both if these and increase the service life, CRK have employed some of the hardest material available, ceramic.

A one-eighth inch ceramic ball with hardness of 97RC acts as the interface between the lock bar and the blade tang. It also doubles up as the detent ball that holds the blade in the closed position. Due to the detent now becoming the locking surface as well, you get a uniquely smooth feel when opening the Inkosi. For just about every other integral/liner lock, when the blade is nearing fully open, the detent ball clicks as it drops off the locking surface of the blade tang. Only after this pre-lock click does the actual lock click into place. It means you get this double click as the blade is opened into the locked position. With the Inkosi, when you start to use it, you’ll notice the absence of this pre-lock click as it is not what you are used to. You open the blade and the only click is the lock bar falling into place. This is only possible with the dual purpose ceramic ball.
 photo 32 Inkosi details lock ball P1230233.jpg

Unlike a standard lock interface, which uses two flat surfaces, we now have a round ceramic ball which would create a point-contact on the blade tang, so instead of having a flat locking surface on the blade tang, the Inkosi has a rounded groove with the same curvature as the ball.
 photo 23 L Inkosi washer lock groove P1200402.jpg

The ball and groove mate securely and this interface also stabilises the lock bar as it can’t flex away from the handle. (NOTE: since the review sample was provided, CRK have found the ball track groove on the tang to be unnecessary, so it is no longer included on current production Inkosi knives.)
 photo 33 L Inkosi ceramic ball P1200442.jpg

Another innovation in the Inkosi is the slip-through stop-pin in the frame. One end of the stop-pin is secured to one side of the frame with a bolt, but the other end simply fits through a hole in the front of the frame and is not fixed in place.
Of course this only works as well as it does due to the high precision of the fit of the stop-pin on the floating side, and this configuration provides an excellent advantage in the operation of the knife.
Traditionally the stop sleeve, which spaces the frame/handle parts, needed to be very precisely sized to ensure that the fit of the assembled knife was tight, but not too tight. If that stop sleeve is a touch too wide you get blade play.
With the slip-through stop-pin, the advantage is that the front face of the handle can move along it as you set your pivot tension. The Sebenza has a stop sleeve that has to be machined to a width accurate within a few tenths of a thousandth requiring a lot of fitting to ensure the knife operates as it should.
From a manufacturing perspective, this feature removes the need for the fitting of the stop sleeve, however, the main advantage is really for the owner of the knife, as the slip-through stop-pin guarantees that even once the knife wears in, the action can always be set perfectly, with no blade play and perfect washer contact, just by adjusting the pivot; the stop-pin will never need any adjustment because it is self adjusting.

A few more details:

Amazing how this box generates a real sense of anticipation and excitement. (NOTE: CRK have subsequently updated the packaging.)
 photo 01 L Inkosi box P1200318.jpg

Personally, I’m not sure a knife should come with a warning it is sharp, but there it is.

Nestled into a foam liner is the Large Inkosi and some accessories.
 photo 04 L Inkosi box tray P1200331.jpg

Along with the Large Inkosi you get a CRK cleaning cloth, two Allen keys for the pivot and one for the spacer and stop-pin bolts. there is also a tube of grease and thread-lock, giving you a full service kit.
 photo 05 L Inkosi box contents P1200337.jpg

Not to skip over this too soon, please note that these are not unbranded tools, you get WIHA Allen keys.
 photo 02 InkosiWasher tools P1230169.jpg

The grease is a fluorinated grease and thread-lock is Loctite 222.
 photo 06 L Inkosi tubes P1200340.jpg

There is something special about that box-fresh CRK knife.
 photo 07 L Inkosi cloth P1200349 copy.jpg

The Large Inkosi arrives with a knotted cord lanyard already fitted to the knife.
 photo 08 L Inkosi cloth2 P1200353.jpg

As with the Sebenza 25, the Inkosi has finger grooves in the handle.
 photo 09 L Inkosi angle P1200355.jpg

Fit, and finish is flawless, just as you would expect with CRK.
 photo 12 L Inkosi pivot pin stud P1200364.jpg

The understated logo sits next to the large pivot bolt.
 photo 13 L Inkosi pivot logo P1200368.jpg

Switching to the back of the frame and you can see the left-hander’s thumb stud, but there is less space between it and the lock bar than for the right-handed thumb stud.
 photo 14 L Inkosi lock side P1200369.jpg

On the back, the pivot bolt looks identical. You can also see the stop-pin bolt as the stop-pin is only fixed to the back of the frame.
 photo 15 L Inkosi Idaho made P1200373.jpg

Start casting your eyes towards that pocket clip.
 photo 16 L Inkosi full lock side P1200375.jpg

Another part of the CRK folder design that has changed is the movement of the clip so that it sits directly onto the frame instead of onto the lock bar. This ensures no additional pressure on the lack bar which might make opening the knife more difficult.
 photo 17 L Inkosi clip angle P1200376.jpg

Giving excellent grip, there is a section of asymmetrical pattern jimping on the thumb ramp.
 photo 19 L Inkosi jimping P1200384.jpg

A single bolt holds the clip in place and can easily be removed if you prefer not to have a clip.
 photo 20 L Inkosi clip fixing P1200387.jpg

To create the lock bar spring, two large radius scallops are cut out of the bar.
 photo 21 L Inkosi lock spring P1200391.jpg

Providing the spot of colour, the ambidextrous thumb stud is blue PVD finish.
 photo 25 L Inkosi stud spine P1200408.jpg

With the blade partway open, here you can see the ceramic ball is out of the detent hole and sitting on the side of the blade tang. Like this the lock bar now stands slightly proud of the frame.
 photo 26 L Inkosi lock bar out P1200415.jpg

When the lock engages, the lock bar has clearly moved into the frame. Also note here how the washer is actually larger than the blade tang.
 photo 27 L Inkosi lock bar engaged P1200419.jpg

The blade has a beautifully even stonewash finish.
 photo 28 L Inkosi angle open P1200420.jpg

Zooming in to the blade tip.
 photo 29 L Inkosi blade tip P1200422.jpg

With the blade now open, both sides of the finger grooves can be seen. The first finger groove is deeper on the front of the frame giving right-handers easier access to the thumb stud.
 photo 31 L Inkosi finger grooves P1200434.jpg

In the assembled knife you can see how the over-sized washers are fitted to the lock bar cutout in the frame.
 photo 32 L Inkosi washer cut P1200437.jpg

A nicely radiused plunge line takes you from the blade grind to the full thickness of the blade tang.
 photo 39 L Inkosi plunge line P1200467.jpg

Though it looks almost like a flat grind, the large hollow grind is noticeable as the light plays on the blade. (Of course it would help if this image was animated, but it is not.)
 photo 40 L Inkosi large hollow P1200473.jpg

There is a gentle curve to the blade spine which is very comfortable to press on. It does mean you won’t be striking sparks of a ferro-rod with it.
 photo 41 L Inkosi spine P1200476.jpg

A close-up look at the thumb stud.
 photo 44 L Inkosi thumb stud P1200499.jpg

On the first run of Large Inkosi knives the washer perforations were a little too large and could be seen when the blade is closed. Not a functional issue, but a potential point for dirt to collect. This washer design has been updated now.
 photo 45 L Inkosi blade tang P1200504.jpg

CRK have really got it spot on with the pocket clip. I generally don’t like them because they are never quite right, mainly too aggressive. In this case the tension is soft enough to be easy to use, but strong enough to hold. The bead blasted surface finish of the frame and clip give plenty of hold without being too abrasive.
 photo 46 L Inkosi clip P1200516.jpg

What it is like to use?

Ok, so this is the Large Inkosi, but how big is ‘Large’? I’ll start with my standard comparison, so here it is next to the Fällkniven F1 and a Spyderco UK Pen Knife.
 photo 52 L Inkosi size P1200557.jpg

Then just for gratuitous CRK viewing, here it is with a Pacific.
 photo 50 L Inkosi with Pacific P1200531.jpg

And in the hand. (I take XL size gloves). So it is not really all that large, it is just the larger size of CRK folder. While we are looking at it in the hand, I’m going to mention those finger grooves. It often seems that the Sebenza 21 vs 25 debate has been very polarising with owners being adamant that the they love or hate the 25’s finger grooves. I was concerned they might be problematic, but for my XL size hands, I can happily say that in all the time I’ve been using this knife I have actually not noticed the finger grooves. Clearly this is a good sign as the knife was secure in my hand but without anything digging in.
 photo 38 L Inkosi in hand P1200460.jpg

Lanyards, hmmm. Not my thing. So this was to come off, but I thought I would just note down how it was tied so I could put it back.
 photo 60 L Inkosi lanyard IMG_20160628_160656.jpg

Loosening the first knot shows it is tied like this.
 photo 61 L Inkosi lanyard IMG_20160628_161111.jpg

And repeated all the way back to the first knot round the frame spacer. And with that removed I started putting the knife to work.
 photo 62 L Inkosi lanyard IMG_20160628_161641.jpg

Although serviceable, I’m afraid the factory edge didn’t have quite enough bite for my liking, so it had a session on the Wicked Edge. Much better!
 photo 67 L Inkosi wicked edge P1250279.jpg

Recycling day was much more interesting now. Here was a large heavy duty box needing to be broken down. Made from ‘BC’-Flute double-wall heavy duty shipping cardboard, this was a bigger job than the average box.
 photo 63 L Inkosi recycling IMG_20170116_183445.jpg

Done. That was easy and enjoyable. Give me another to do.
 photo 64 L Inkosi recycling IMG_20170116_184731.jpg

The last cut through this was crisp as the blade slid through with ease. Feeling just as smooth in the cut as a full flat grind, possibly even smoother as there is less blade to material contact than with a FFG.
 photo 65 L Inkosi recycling cut IMG_20170116_184810.jpg

Outdoors and the Large Inkosi makes quick work of wood carving. Even when applying a good force to the cut, the finger grooves in the handle were not noticeable.
 photo 66 L Inkosi in the woods P1250177.jpg

CRK have taken their already time-tested design and made several improvements to it, improvements you might never actually notice in real world use, unless you push the knife to its absolute limits. I suspect many CRK owners appreciate knowing that the knife is as good as it can be and that if they really did need to push it further than normal, it won’t let them down.

The Large Inkosi is the next generation of a classic folding knife from CRK, and has been designed with such a thorough and thoughtful attention to function and detail that it is more than just a knife; it is a highly desirable object and a pleasure to use.

Review Summary

The views expressed in this summary table are from the point of view of the reviewer’s personal use. I am not a member of the armed forces and cannot comment on its use beyond a cutting tool or field/hunting knife.

Something that might be a ‘pro’ for one user can be a ‘con’ for another, so the comments are categorised based on my requirements. You should consider all points and if they could be beneficial to you.

Light Review: Rofis TR20

Rofis were the first manufacturer I came across which have made a standard tubular light that transforms into a right-angle light. They have applied the same principle to a couple of different models, and in this review we are looking at the TR20, which is an 18650 powered model with built in USB charging, making it an all-in-one lighting solution.

 photo 00 Rofis TR20 feature P1240405.jpg

Taking a more detailed look:

The TR20’s box.
 photo 01 Rofis TR20 box P1240376.jpg

Included in the box is the TR20 (with 3400mAh cell inside), holster, USB cable, wrist lanyard, two o-rings, a spare USB port cover and the instructions.
 photo 02 Rofis TR20 box contents P1240379.jpg

The UBS cable is of a nice quality with metal plugs and a braided cable.
 photo 03 Rofis TR20 USB Cable P1240385.jpg

On the holster there is an apparently overly long patch of Velcro, but we shall see about that later.
 photo 04 Rofis TR20 holster P1240389.jpg

There are three loops on the holster, a D-ring, a fixed belt loop and a loop secured with a press-stud.
 photo 05 Rofis TR20 holster loops P1240393.jpg

And here we have the TR20 in its ‘normal’ tubular configuration.
 photo 06 Rofis TR20 angle P1240396.jpg

Switching round for a different view.
 photo 08 Rofis TR20 rear angle P1240415.jpg

Fitted to the TR20 is a long steel pocket clip.
 photo 09 Rofis TR20 clip P1240418.jpg

The tail-cap has a plain appearance, but the very end looks slightly different.
 photo 10 Rofis TR20 tail P1240421.jpg

The explanation for the way the tail-cap looks is that screwed onto the end is a removable magnet.
 photo 11 Rofis TR20 magnet off P1240425.jpg

Inside the tail-cap there is a gold plated spring contact. Bare threads mean there is no physical lock-out.
 photo 12 Rofis TR20 tail contacts P1240430.jpg

As the TR20 ships with the 18650 inside, it comes with an insulator which you need to remove.
 photo 13 Rofis TR20 insulator P1240434.jpg

Square cut threads are used for the tail-cap.
 photo 14 Rofis TR20 threads P1240437.jpg

It is a Rofis branded cell that is included.
 photo 15 Rofis TR20 cell P1240440.jpg

An unnecessary detail, but a nice touch is that the negative terminal has the Rofis logo etched into it.
 photo 16 Rofis TR20 cell logo P1240442.jpg

The positive terminal is gold plated.
 photo 17 Rofis TR20 cell positive P1240446.jpg

Opposite the control switches is the rubber USB port cover.
 photo 18 Rofis TR20 USB cover P1240449.jpg

Using your nail, you prise the hinged cover out.
 photo 19 Rofis TR20 USB cover open P1240452.jpg

Here the supplied USB cable has been plugged in for charging.
 photo 20 Rofis TR20 USB connect P1240462.jpg

While charging, the red indicator light in the dual switch is on. Once charged this will go green. Also note the dual switch where the front part is the mode change switch and the rear part is the power switch.
 photo 21 Rofis TR20 USB charging P1240458.jpg

The smooth reflector does have a few visible machining marks in it, but these don’t aversely affect the beam.
 photo 22 Rofis TR20 reflector P1240463.jpg

A XP-L Hi V3 LED is used.
 photo 23 Rofis TR20 LED P1240473.jpg

So, the reason for the extended Velcro area on the holster is so that when the TR20 is transformed into a right-angle light the flap folds over further and still fits the TR20 perfectly with the lens sticking out sideways.
 photo 24 Rofis TR20 holster 90 P1240475.jpg

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and the wife won’t have one!

Starting indoors, the TR20 does have a bright hot spot, but the transition to the spill is smooth and the spill is sufficiently bright that the beam does not appear unbalanced.
 photo 25 Rofis TR20 indoor beam P1240743.jpg

Moving outdoors you can see how the spill is nice a bright and gives a good view. Though not a flood beam, the beam has a good useful width.
 photo 26 Rofis TR20 outdoor beam P1240696.jpg

Modes and User Interface:

The TR20 has 6 constant output modes (Turbo, High, Mid, Low, Lower and Ultra-Low) and three flashing modes (Strobe/Beacon/SOS) controlled by a dual button.

From OFF, to switch ON to the last used constant output (not including directly accessed modes), briefly press the Power switch. When ON, press the Mode switch to cycle through Turbo -> Ultra-Low -> Low -> Mid -> High back to Turbo etc. To switch OFF briefly press the Power switch.

From OFF, for direct access to Turbo, press and hold the Power switch for more than 1s.

From OFF, for direct access to Ultra-Low, press and hold the Mode switch for more than 1s.

To access flashing modes, from ON, press and hold the Mode switch for more than 1s. This will activate strobe. Press and hold the Mode switch for more than 1s again to switch to Beacon mode. Press and hold the Mode switch for more than 1s once more to activate SOS.
Once activated, pressing the mode switch briefly returns the TR20 to the previous steady mode, or a brief press of the Power switch will turn the TR20 OFF.

The TR20 is Strobe-Ready and to activate Strobe directly from OFF, double-click the mode switch.

There is a lockout mode included. With the TR20 OFF, press and hold both buttons simultaneously for 3s to enter lockout. When entering Lockout, the TR20’s red indicator light in the dual switch will come on to indicate Lockout has been activated. Like this the buttons will not turn the TR20 on. To exit Lockout press and hold both buttons simultaneously for 3s and the TR20 will turn ON in Low mode.

Lastly when turning the TR20 ON, or changing mode, after 3s the dual power switch will light up to indicate the remaining battery power. This will light green if there is more than 50% battery left, red if there is less than 50% and will flash red if the battery is low.

Batteries and output:

The TR20 runs on a standard 18650 which is supplied.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 15600 lx @1m giving a beam range of 250 m.

There is parasitic drain at 83.8uA. When using a 3400mAh cell it will take 4.63 years to drain the cell.

At switch-on the near 900lm output is short lived and after only around 30s starts to decline to the 750 running output. There are some unexplained dips around the 15 minute mark where the output briefly drops to 560lm but then goes back up to 750lm again. After 20 minutes from switch-on the TR20 no longer maintains regulation and the output starts a steady decline until the end of the ANSI runtime at 2h 15m.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The TR20 in use

Right-angle lights are incredibly useful and bring an added dimension to the function of a light. Personally I find the variety of grip options they bring make them amongst the most comfortable to use, with a natural pointing of the beam as well as allowing various arm and hand positions that still direct the beam forward where you want it. If I had to choose between a straight or right-angle light it would be a right-angle that I would choose, but there is a definitely a place for the straight tube light. Why have to choose one or the other when you can have both?

Having a dual-switch does make the UI very functional, but these types of switches don’t work so well when using gloves as you can’t feel the two parts of the switch. For gloved hands the two switch parts are a bit small so you can miss the part you meant to press. Gloved use may not be the highest priority because this light is not a tactical light, it is a utility light.

Another example of how functional this light is, is the holster that adjusts to the straight or right-angle configurations. But there is more. When in the right-angle configuration, the control buttons now line up with the gap on the side of the holster opposite the lens. In this way you can operate the TR20 when it is still in the holster giving you easy access and hands free use; this is the real benefit.

USB charging and the use of a standard 18650 cell adds convenience and ease of carrying a spare cell. The power indicator which tells you ‘Over 50%’, ‘Under 50%’ and ‘Empty’ is better than nothing, but might tend to lead you to keep topping up once you hit ‘Under 50%’. At least you only need to flip the USB port cover aide and hook it up to your USB charger.

One aspect that very much surprised me, and it is one I’ve heard others have found, is that the rotation of the head to transform to and from the right-angle configuration is very stiff. I’m known for a pretty strong grip and am the person at the archery club who is asked to pull out the arrows others can’t. I say this as I feel that if I find this too stiff, I think there are plenty of people who would struggle with it. Clearly you don’t want the head swing back round to straight, and this certainly won’t, but you do want to be able to transform it easily. Another way to look at it though, is that any concerns that the articulation of the head might introduce a weakness certainly doesn’t seem to be the case.

The instructions say that the last used output mode is memorised, but doesn’t mention that this does not include a mode activated by the direct access option. Only the mode set when the TR20 is on and the mode switch pressed to choose the level is memorised. As I typically use the Ultra-Low level, this is the reason I’ve become aware of this. To be sure you get the lowest level you will need to use the direct access method for Ultra-Low rather than relying on the ‘last used’ mode. This behaviour is good as you end up with direct access to one additional mode; if you have memorised medium, but have used the direct access to get ultra-low, simply switching it off and on again gets you back to medium.

Magnetised lights leave me in two minds; I find them more annoying than useful as they stick to everything I didn’t want them to, the TR20 completely removes this annoyance by making it very easy to remove the magnet, and not only that, but the threaded hole left where the magnet was will fit onto a tripod.

A quick observation about the lockout mode; As the only indication you have entered lockout is a flash of the red indicator in the dual switch, when you are pressing both parts of the dual switch, your fingers mostly hide the red light. It would be easier to see if the main LED was given a brief flash to let you know it was going into lockout.

Pocket clips are normally something I strip off straight away, largely because they are often too stiff and damage the pocket. Rofis have got this clip spot on. It is long and stable, yet the spring force is low enough not to be harsh and damaging. Add to this the right-angle configuration and the pocket clip is much more practical than on many lights.

Overall, the ability to transform the light into two different configurations overrides any minor quibbles with this light and makes it very attractive and very useful.
