Showcase: BKS Gembloux 2017 Knife Show

The Belgian Knife Society Show in Gembloux is one of those exceptional events. Taking over the entire Gembloux Town Hall, this annual show attracts hundreds of knife makers from all over the world, and a flock of knife enthusiasts eager to see the amazing work on display (and buy a lot of it).

‘Showcase’ on Tactical Reviews:

The ‘Showcase’ is an opportunity for me to share some photographs, videos and thoughts about interesting or exceptional shows/exhibitions, knives, lights or other gear.

As well as all the exhibitors and demonstrations, the Belgian Knife Society (BKS) arranged for a couple of seminars. Tactical Reviews was there to record these excellent speakers and their words of wisdom.

The following videos are much longer than I would normally publish, but the information in them is very interesting and worth listening to. They are informal, so imagine you are really there in the room.

“The Complex Structure Of Viking Blades”

Owen Bush, (Bladesmith, Swordsmith and artist Blacksmith based in the London/Kent region of England – UK) explains the Viking forging techniques and using modelling clay Owen shows how the intricate pattern welded designs are formed in Damascus blades.

Light Review: Fenix TK25 R&B – LED Swapping Design

Fenix have embraced multi-coloured, multi-functional lights with many models available in their range. Often these will feature additional LEDs shoehorned into the head with the reflector being compromised. The TK25 is the first to feature the ability to swap the primary LEDs, effectively making the TK25 a fusion of two completely different lights. Simply twist the head, and change to a second set of primary LEDs. The model on test is the (non-musical) R&B version with White, Red and Blue LEDs.

Taking a more detailed look:

Recognisably a Fenix box with Orange highlights.

As well as the TK25 there is a holster, instructions and a small bag with O-ring and wrist lanyard.

Due to the size of the head, the TK25 will only fit into the holster head-up.

On the back of the holster is a fixed and Velcro belt loop as well as a D-ring.

The holster is actually a universal holster with an adjustable flap. Here you can see the loop that keeps the flap from tearing away from the Velcro adjustment. The end of the flap passes under this loop and into the holster compartment, where its length is set using the Velcro adjustment.

Looking again from the side, you can see the additional ‘loop’ area on the flap which can set the flap to a much tighter/smaller position.

Incorporating two primary LEDs (at a time) the head of the TK25 is relatively large, and the two reflectors do intersect.

The model is laser engraved onto the side of the head.

And now let’s look at that head and what it does. On the battery tube is a dot to mark which set of LEDs are currently selected.

As you turn the head it lifts up, so it doesn’t hit the LEDs. As you continue to turn, it drops back down unto the next set of LEDs.

With the indicator set to ‘C’ the XP-E2 (red & blue) LEDs are active.

With the indicator set to ‘W’ the XP-G2 S3 (white) LEDs are active.

Looking at a slight angle as we swap LEDs, starting with the white XP-G2 S3.

The reflector has now lifted off the LEDS.

And now dropped back onto the XP-E2 LEDs.

Back to the some of the other details, and the tail-cap threads are bare aluminium.

As with Fenix’s TK32, the TK25 features a battery tube sleeve that provides another connection between the tail-cap and the head (and makes it difficult to try and measure any parasitic drain).

Inside the tail-cap there is the third contact surrounding the central spring that connects to that battery tube sleeve.

On the tail-cap is a set of two switches, the main tactical switch and a smaller click switch for mode changing.

Peering into the battery tube shows the positive contact is a spring and this allows for the use of flat-top cells.

A steel pocket clip is supplied fitted to the TK25.

With the dual-switch tail-cap and a lanyard hole on one side, the TK25 cannot tail-stand.

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!

When running in white output, the TK25 has both LEDs lit. There is a dual compound reflector, so in the outer spill you can see some imperfections in the beam. However the main spill and hot-spot are well formed. With two LEDs running you will notice some double shadow effects such as that shown by the newel post shadow on the stairs.

Now with Red output, only one LED is running and the missing part of the reflector (due to the two reflector cones intersecting) shows as a bulge in the outer spill at around 4 O’clock in this picture.

Switching to Blue and the same bulge in the outer spill is present, this time in the opposite 10 O’clock position.

Moving outdoors (and excuse the murky weather causing the beam to show up more than it would normally) and the small reflectors are showing some limits in the brightness of the spill, but the centre of the beam still has good range.

With only a single LED, the Red beam appears more focused, and the spill is slightly wider.

The Blue output has a similar appearance to the red, but as I’m hand-holding the TK25 here the alignment is not quite the same.

Modes and User Interface:

The TK25 has a dual-switch tail-cap with the main power switch being a momentary tactical switch and the secondary oval click switch is for mode changing.

There are four constant white levels – Turbo, High, Med and Low, plus a Strobe mode. Changing LEDs to the coloured set and there is also a Red High, Red Low, and Blue output.

As a main feature, the TK 25 has the rotating head to change between sets of LEDs, so as a starting point the first thing to do is to rotate the head to the appropriate set of LEDs. This is assumed in the following description of the operation of the TK25.

To access the White constant modes, either half-press, or fully press and click the tactical switch. The TK25 will come ON to the last used constant output level. Press the mode/function switch to cycle through the levels Low, Medium, High, Turbo, Low etc. Release the tactical switch or click again to switch OFF.

For strobe, either, from OFF press (and hold) the mode switch (while doing this you can click on the tactical switch to lock the output on to strobe), or turn the TK25 onto a constant output mode by clicking on the tactical switch, then press and hold the mode switch for 2s. To stop strobe, depending on which method you used, either let go of the mode switch, or press the mode switch to return to constant output.

The coloured outputs operate differently. From OFF, the TK25 will always come onto Red High when pressing and holding the mode switch, or half-pressing or fully clicking the tactical switch. To access the Red Low and Blue modes, the TK25 must be ON (defaulting to Red High), then press the mode switch to cycle through Red Low, Blue, Red High etc. There is no coloured flashing mode.

Rotating the head while the TK25 is ON will swap you between the Last Used White mode, and Red High. Even if you were using the Blue output, swapping to White and back again will revert to the default colour output of Red High.

Batteries and output:

The TK25 runs on one 18650 (recommended) 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.

Medium 113 0

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

It was not possible to measure any parasitic drain due to the contact design.

Typically Fenix lights display fully regulated output, but in this case the Turbo output on the TK25 is sagging over the first hour. This may well be due to running the test with a Fenix 2600mAh cell, and if run with a higher current cell, it might have appeared stronger than this. Once the output has sagged to around 300lm, the TK25 shifts down to the medium output level, continuing on this until it shifts down again and ends the ANSI runtime, however the TK25 was still running on low at this point.

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 TK25 R&B in use

The whole concept of swapping the primary LEDs is one I really like, and Fenix’s take on this makes a lot of sense as it allows for the LEDs to be permanently mounted onto the heat-sink, with the reflector assembly (which has no electrical or thermal connections to worry about) moving. However this does introduce two compromises in the reflectors as firstly each LED’s reflector is relatively small, and secondly the two reflectors intersect and so have a part that is missing. The only way to overcome this would be to make the head even larger than it is, or maybe even removing one reflector and making the TK25 into a four-in-one light with only one (rather than two) active primary LEDs.

With the moving parts, this is better shown with a short video:

One little annoyance, made very obvious due to the head needing to be rotated, is that the pocket clip keeps slipping round whenever you turn the head. Considering the requirement to turn the head, it would be better if the pocket clip was anchored in place so it could not turn. A minor point perhaps, but I don’t like parts moving that should not be.

The switch design does work nicely thanks to the second mode switch being placed onto a slightly lower angled area. It keeps it clear of the main switch, yet remains easily accessible.

Though the are some milled out areas around the head, these don’t really do much for anti-roll, but the pocket clip does, so it will stay put on gently sloping surfaces once it rolls round to the pocket clip.

With Fenix generally having such good mode sets and interfaces, I was slightly disappointed that the coloured output defaults to Red-High, instead of memorising the last used mode like the white output does. When a light includes a pure Red output this is more often than not used for preserving night vision – in which case it is vital to start on the Red Low output. I’d also like to be able to use the Blue output on momentary when I want to. Perhaps this is a restriction to stop users flashing the blue light (imposed by Law Enforcement Agencies), in which case that is understandable if a little frustrating.

The small reflectors do result in a narrower beam than I’d personally like, but they are the compromise for having two ‘proper’ sets of LEDs available in one light. Though not perfect, the beams of all the LEDs are significantly cleaner than typical multi-colour lights, giving the TK25 a significant advantage over the fixed designs with ‘secondary LEDs’.

Review Summary

Light Review: Nextorch P5x Series with ‘Dual-Light’ LED Swapping Mechanism

Multi-LED lights have always had to compromise the main beam by using multiple smaller reflectors or combined ‘compound’ reflectors, both of which affect the beam considerably and create many beam artifacts. With such powerful LEDs to choose from now, it has become more desirable to make the humble torch/flashlight more versatile by giving it more options. Nextorch have re-thought the concept of multi-LEDs, and designed a ‘Dual-Light’ system that allows the user to actually swap the primary LED that is positioned at the focal point of the reflector, so fully maintaining beam quality. The P5x series of lights (part of the ‘Police’ Series) use a special mechanism that changes the active LED and moves that LED to the centre of the reflector, ensuring the beam quality is uncompromised and giving you two beam options in one light.

Taking a more detailed look:

A few different versions of the P5x were provided, and they had slightly different packaging. The box at the front shows the six variants you can choose from; P5G, P5B, P5R, P5W, P5 UV and P5 IR.

For one of the box styles, this is the inside.

The other box style has a moulded plastic tray insert.

Either way, you get the P5x a Nextorch 18650, a USB charging cable, a lanyard and the instructions.

The LED changing mechanism and built-in USB charging blend into the simple, elegant design.

A flattened section of the grip texture provides a space for the engraving.

If you want to add a lanyard to the P5x, you need to snap on the lanyard ring.

The lanyard ring sits tightly into a groove near the tail-cap.

A sleek tail-cap design hides the USB charging very well.

The power switch protrudes slightly and is easily accessible, however no tail-standing is possible.

If it were not for the small engraving of the USB symbol and an arrow, you might miss the charging function.

Following the arrow, simply pull the tail-cap sleeve up and turn it sideways to lock it open.

A micro-USB socket is used for the charging.

USB charging cable connected.

Opposite the USB socket is a charging indicator light. Red while charging, Green when fully charged.

Taking off the tailcap, the negative contact is a sprung button instead of an exposed spring.

The threads are a standard trapezoidal thread and are bare aluminium.

Peering into the battery tube, the positive terminal is a spring.

Looking closely at the head of the P5x, there is an indicator arrow. Here the White LED is selected.

And now the Green LED is selected.

Our first close-up look at the textured reflector and dual LEDs. The white LED is in the central position.

Now the green LED is centred and active.

With the White LED on.

Then the Green LED on.

White LED centred in the reflector. (Note the yellow phosphor colour.)

Green LED centred in the reflector.

Going in even closer with the XP-L V5 LED in the central position and the green XP-E2 LED to the side.

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!

Each P5 light features a white LED (XP-L V5), so I’m only showing one of these as they all look the same. With this being a dual-LED light, the beam is very clean without the artifacts you might expect from a multi-LED light. The spill is a medium width and the hotspot transitioning smoothly into the even spill.
All of the beamshots shown here have the same exposure for all beam variations.

Now onto the interesting secondary-LED options. The Warm LED is quite warm (XP-E2 Warm), in fact it is reminiscent of a good old incan but without the curly filament artifacts. The camera is set to daylight for all beamshots to show the relative colour shift. As with the white beam, the Warm beam is clean and free of artifacts.

Similarly with the green (XP-E2 Red), a nice clean beam.

Being UV (1000mW UV), this beamshot is not a very good representation as there is no fluorescent material in the beam; it makes it look very dark.

An lastly the Red LED (XP-E2 Red). The spill of this beam is slightly wider than the other colours.

Moving outdoors now. Again all exposures are the same. Starting with white.

Onto Warm White.

Green.

Clearly UV is not ideal for lighting up your garden, but that is not why you use it. You can see that there is a good throw, despite the lack of fluorescent materials.

And lastly Red. In this case it was a different evening and there was a light rain which is why the beam is showing up more strongly.

Modes and User Interface:

All of the P5x models have the same simple set of modes and user interface.

Control is via the forward clicky tail-cap switch, and there are two constant modes, High and Low as well as Strobe and SOS. Of course with the Dual-LED, this is the same for each LED.

To Switch ON to High, from OFF, half-press or fully press the switch. Momentary action is always on High.
To access the Low mode, from ON with the switch clicked fully on, half-press the switch briefly to access Low. Low can only be accessed from High with the switch clicked ON.

To switch OFF, either release the switch, if only half-pressing it, or press it fully to click it off.

For Strobe, rapidly double-tap the switch from OFF. This must be half-presses, and once Strobe is activated, you can fully click the switch to lock it on.

For SOS, first the P5x must be ON with the switch fully clicked. It can be in High or Low. Then half-press the switch for 3s and SOS will start.

LED swapping is via the control ring at the base of the head. Rotate this to select the LED. You can do this at any time, whatever mode is selected.

Batteries and output:

The P5x runs on a single 18650, which it can recharge, or two primary CR123s.

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 of the measured 16400 lx @1m giving a beam range of 256 m.

There is parasitic drain at 11uA (27 years to drain the cells).

In this first runtime graph there is also a trace from the green output of the P5G. Compared to the white output, this is longer and lower so is included here to give an indication of the reduced efficiency of the coloured LED.

In the second graph the green output has been removed to better show the white outputs. Instead look at the White output from the P5UV and the Warm output from the P5W. Again the cool white LED is more efficient and provides a longer runtime. The Warm White keeps up with the Cool white up to about 2 hours, then drops off with the Cool white running for another couple of hours.

Troubleshooting

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 P5x series in use

I first saw the Nextorch Dual-Light mechanism at IWA 2016 and immediately loved the idea. I asked them if they could add a third LED – yet to be seen – and the reply was ‘maybe’; we can live in hope.

Having used many multi-LED lights with different colours in them, though useful, the beams of the secondary LEDs were always badly compromised, and even the main beam was compromised. The Dual-Light is a revelation with the main LED effectively being swapped with a twist of the selector ring – you don’t even need to turn it off.

A trio of dual-lights getting ready to go.

We have had a detailed look over the P5x lights already, but to really show the mechanism, this is a short video of the way it works.

Although it has the LED swapping function, Nextorch have made the P5x a simple and functional light without any external frills. The LED control ring has slightly raised grips which provide a degree of anti-roll, at least enough for relatively level surfaces. There may not be a ‘tactical grip ring’ but the slightly wider tail-cap is enough to let your grip the light securely, and the grip pattern works well (it is not knurling, as the pattern is cut, not rolled).

Fitting the lanyard ring also gives a little more grip (plus you can have a lanyard), but in doing so, I managed to scratch the anodising both fitting and removing the ring, so if you are going to use it, fit it once and leave it on.

Of course it is very convenient to have built-in USB charging, especially if you travel with the light. What would have been useful is to have some indication of the state of charge. There is none, so it is difficult to know if you need a charge or not. Unfortunately this leads to regular topping-up rather than a more planned approach to charging.

Though limited to two output levels (and I generally prefer a few more options including ultra-low) those levels are well chosen for most uses. The lower level at around 40lm is great for indoor use and is perfectly comfortable to use at close range, and the 700lm High level is a good powerful output which a single 18650 can power without being over-burdened.

In the case of Nextorch’s Dual-Light P5x models, the ‘secondary’ LED is actually not secondary at all, instead you have two ‘primary’ LEDs both of which have full and uncompromised use of the reflector, making them as good as dedicated lights using the same LEDs. Your only difficult choice now is which combination of LEDs to go for.

Check out the Nextorch P5x lights on the Nextorch Website here.

Light Preview-Review: Jetbeam TH20 Prototype

In this special preview review of Jetbeam’s new TH20 we take a look at a prototype of this super powered single 18650 Tactical Hit Series light. Featuring an extreme output XHP70.2 LED, over 3000lm peak output capability, a new triple-switch tail-cap, a dedicated high current ICR cell, but full compatibility with all standard 18650 cells (flat or button top) as well as CR123 cells, this light has a lot to be interested in.

UPDATE – New Tail-Cap and Reflector Swap – Included at the end of the review.

Taking a more detailed look:

Though it was supplied in a Jetbeam box, as this is a prototype, the TH20 packaging is not finalised, so I’m not showing it here. It may be a single 18650 light, but with such high output ratings, the light is somewhat chunkier than most lights in this class

In this case the TH20 was supplied with an open bottom holster, offering only head-up carry. The holster has a D-loop, and both fixed and Velcro closing belt loops.

The ‘TH’ model prefix comes from being part of the Jetbeam Tactical Hit series of lights.

On this prototype it also has the Niteye branding engraved. I don’t believe this will be included on the final production version.

Apart from the huge output, one of the TH20’s special design features is the triple switch tail-cap. Surrounding the central forward-clicky tactical switch is a rocking paddle-switch which activates when pressed on either side. This gives quick and immediate access to the secondary function whichever way round you are holding the TH20.

Two posts protect the main switch from accidental activation and to a degree protect the paddle-switch; they also hold the pivot pins for the paddle-switch. Note that as this is a prototype you can see the pivot pin protruding slightly which it would not on a production model.

A set of cooling find surround the base of the head where the LED mounting board is located.

Inside the tail-cap shows there are several things going on. The negative contact is a double spring with one sitting within the other. As well as the bare threads that make up a connection, there are a set of contacts around the circuit board. Since this prototype was made, the design has been updated.

Square threads are used which are bare aluminium as they form one of the electrical contacts.

To enable the triple-switch tail-cap design to work, there are extra contacts in the tail-cap, and in turn this needs there to be an additional tube fitted within the body of the TH20 allowing this extra connection to be made from the head to the tail-cap. This design feature is the reason I’ve not been able to measure operating current and parasitic drain for this light.

In this sample, the XHP70.2 LED sits in a textured reflector.

That XHP70.2 LED is a bit of a monster, and is classified by CREE as an ‘Extreme High Power LED’.

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 a large LED, and a relatively small head (being a single 18650 light) with textured reflector, the TH20 could have been all flood, which, though no bad thing, might be a waste of such a powerful output. However, the TH20 is not all flood, instead you have a well balanced beam with smoothly transitioning hotspot and uniform spill of a reasonable width.

Increase the range, and the hotspot blends even more and you have a super area-light with nothing given a chance to hide in the bright beam.

Modes and User Interface:

The Jetbeam TH20 has four fixed output modes (Turbo, High, Middle, Low) as well as Strobe, however, the output level of the Turbo and Strobe modes depends on if the TH20 is set to High-rate or Low-rate mode.

The TH20 has a special triple switch tail-cap with central forward-click button and a pivoting paddle-switch which provides a button either side of the main click-switch.

As the TH20 is able to work properly with either the special high-discharge cell it is supplied with, or any standard 18650 cell (or even 2xCR123), the design incorporates two output levels for Turbo and Strobe (High-rate or Low-rate). This is set after a new cell is inserted into the TH20.

By default, the action of removing and replacing the cell resets the TH20 to Low-rate mode (and Turbo output). To activate High-rate for Turbo and Strobe, switch ON the TH20 by fully clicking the main switch, then rapidly triple-click either side of the paddle-switch. The output will briefly turn off then on again to indicate it has changed to High-rate output. It will do this whatever output level you are currently using, even Low, but you have prepared the TH20 for High-rate output when using Turbo and Strobe.

To turn onto the last-used constant output mode, either half-press (for momentary use) or fully press-and-click the main switch. To cycle through the output levels Turbo -> High -> Medium -> Low -> Turbo etc, briefly press the paddle-switch.

To access Strobe from OFF, press and hold either side of the paddle-switch. If you hold for less than one second the output is momentary, but if you hold the paddle-switch for more than one second the Strobe will stay on. To turn OFF, either tap the paddle-switch again, or turn the main switch on to activate a constant mode.

To access Strobe from ON, press and hold the paddle-switch and after one second Strobe will start, and stay on for as long as you hold the paddle-switch.

Batteries and output:

The TH20 runs on the supplied specialised high current ICR 4.2V 18650 cell, and when using this cell can be set to run in High-rate output mode. Of course if it could only run on this special cell it would make it a bit limited, so Jetbeam have made the TH20 fully functional using any standard 18650 cell or 2x CR123 cells, but on a ‘low-rate’ Turbo/Strobe output.

The TH20 can use button-top or flat-top cells.

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.

It was not possible to measure parasitic drain due to the double wall battery tube design.

There are several graphs to look at for the TH20 as it provides us with a lot of interesting information. In this first graph are four main power options and their output profiles. These are the High-Rate 18650 supplied with the TH20, a standard 18650 cell (an AW 3100mAh), a 20A IMR 18650 (Efest) and CR123. The CR123 is clearly a backup option only and struggles on the Turbo output. What is pleasing to see, and makes the TH20 very attractive, is that the 20A IMR is really not far behind the specialist cell Jetbeam provide. This means you can easily feed the TH20 with readily available cells.

Looking in at the first part of the graph you can see more easily how the HR and IMR cells run on the High-rate output, and the 18650 and CR123 run on the low-rate output. The CR123s don’t manage any form of ‘burst’ output for Turbo.

To really see what the TH20 can do, in the next test I pushed it to the max by switching it off and on again to reset the Turbo output every time it ramped down – this was to push it as hard as possible. The test was carried out with a strong cooling fan and during this test the highest recorded temperature anywhere on the TH20 was 47C.

Expanding the first part of the graph where the TH20 is working really hard, shows that with a fully charged cell the TH20 can manage three full output bursts, before the bursts start to reduce. After 8 full bursts, the output then drops to under 2000lm, but is still well over 1500lm.

In this last graph I’ve included a direct competitor for the TH20, the NITECORE TM03. The measurements were taken at the same time in the same conditions using the cells supplied by the manufacturers, so is the closest comparison I can make. It is however not the full story. The TM03 is much more dependant on the specialist cell whereas the TH20 is much more compatible and runs very well on an IMR. Also note that though the TM03’s initial burst is longer, the output drops much more, so the TH20 maintains a brighter running level.

Troubleshooting

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

Being a prototype troubleshooting is not that relevant, however just to mention that the original prototype tail-cap design shown has been changed and improved during this preview testing process.

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 TH20 in use

Extreme output lights have their limitations, and you need to understand these to get the most out of yours. One of those limitations is that you will only get those magical monster output figures from fully charged batteries. Once you get down to 80% cell charge or less and those outputs are drooping severely. So how practical are they?

There are several things about the TH20 that for me make it a great deal more practical than some of the other options. The first of these is its support of various power options, from the high-rate special 18650 cell shipped with it, to the ever reliable CR123 which you can use as a backup. Then, to accommodate this feature, Jetbeam have taken a very clever approach of having the TH20 run in two modes, either high-rate or low-rate, for the Turbo and Strobe outputs. If you know the battery you are using can take it, you can switch to high-rate and get that extreme output, but if not, you can leave it in low-rate and run the TH20 in a more typical (but still bright) single 18650 output.

To make this as simple to live with as possible, the TH20 defaults to the low-rate mode whenever the tail-cap is fully removed (as you do when chancing the cell), so you never need to worry about being in the wrong output mode. Should you want to use high-rate output, then turn it on, triple tap that paddle-switch and off you go. If you switch the TH20 into High-rate with a protected 18650 that cannot deal with the current, you will find a very effective way of testing the protection circuit (it will trip).

In true terms, for LEO and Military ‘tactical’ use, a switch needs to be as simple as is can be. In times of high stress you won’t be thinking about modes, or where your thumb is, or where a switch is; you want to hit a big button and have the light come on. Multi-switch, multi-mode lights will, I think, always be more appropriate for enthusiasts or home/self defence users than the professional, but I’ll let you make you own mind up on that.

Having said that, I do think this is one of the best multi-function tactical tail switches I’ve used. Starting with the relationship between the switch and the raised posts either side of it, there is a good amount of protection from accidental activation, yet still plenty of access to the switch, even if you have to go over the top of those posts to press the switch.

The secondary switches both perform the same function so it doesn’t matter which one you hit. Interestingly your thumb most naturally falls onto the main power switch without hitting these secondary switches and you need to positively move your thumb to press them, which is further helped by their rounded edges. To be clear, this is a good thing, as accidentally blasting yourself with over 3000lm of strobe is NOT a good thing, and changing modes when you didn’t want to is also bad. The combination of easy to reach, whichever way round you hold the TH20, and difficult to press by mistake, makes the TH20’s additional switches on the tail-cap a well implemented feature.

Beware that whenever you change the battery or remove the tail-cap, the TH20 will reset to Turbo output. I’ve found this a little frustrating as I’d definitely prefer to start on Low and work my way up, especially if trying to conserve power. However it could be argued that in a ‘tactical’ situation, that after changing the battery you might want to go straight to maximum output.

Another aspect I was not so keen on was the order of the modes. I prefer to change up through modes, starting low and working up in brightness. The TH20 starts high and works down, so taking the default of a new battery being fitted, you are on Turbo, and then have to go to High, Medium, then Low (and then back to Turbo). Again, as with the previous point, in a ‘tactical’ situation, it is preferable that if the mode switch is accidentally pressed, instead of going from Turbo to Low, you go from Turbo to High, still leaving you with lots of light; so being a ‘Tactical Hit Series’ light the design choice makes sense.

Of course, the TH20 is bigger and heavier than most single 18650 lights, but that is because it houses an extreme output LED and the circuitry needed to drive it, giving you the ability to output bursts of over 3000lm. The TH20 is a heavy-duty single 18650 light that, thanks to that extra mass and solid build, even during the stress test (where the it was run at a constant maximum output by resetting every 60s), did not heat up excessively, nor suffer from thermal output throttling.

By using the easily available 18650 for power but staying away from proprietary cells, Jetbeam have really done us a favour and made the light much more useful, versatile and future-proof.

UPDATE – New Tail-Cap and Reflector Swap:

This update includes a few details not available when the review was originally posted. The tail-cap design has been updated and there are two reflector options. With my preference for (OP) textured reflectors, I’ve swapped the reflector in the newer higher output sample.

Starting with the prototype, the bezel ring is unscrewed and the lens, o-ring and reflector are easily taken out. If you do this make sure you don’t touch the inside of the reflector.

The lens is a good thickness, being nearly 3mm thick.

There is a groove around the reflector for the o-ring to sit in.

Here are the OP and SMO reflectors.

Before putting things back together, a quick look at the brass pill with LED and mounting board.

Although the initial prototype will be shelved, it has the SMO reflector fitted to show both options.

Lastly, we have the updated contacts inside the tail-cap. To save lots of scrolling back up, first here is the prototype tail-cap.

Then we have the updated version.

Knife Review: Spyderco SpydieChef

Sometimes it’s all in a name… and ‘SpydieChef’ immediately lets you know this is a small (folding and EDC-able) Spyderco Chef’s knife. Of course it is a blend of exotic ingredients, made to that special Spyderco recipe, and is capable of so much more than just chopping a few vegetables. The SpydieChef is designed to deal with all-round EDC tasks as well as kitchen duties, is built using ultra-corrosion-resistant materials (it is a member of Spyderco’s Salt Series), and is finished to the high level of quality that we have come to expect in Spyderco products.

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.

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).

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.

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.

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 LC200N steel, a state-of-the-art nitrogen-based alloy, which is extremely corrosion resistant and is actually used by NASA for the ball bearings used in aerospace applications.

A few more details:

Spyderco’s standard sleeve box is used for the SpydieChef.

Inside the box the knife comes in a bubble wrap bag along with a product information leaflet.

Let’s just take a moment to appreciate those lines…

Using flat Titanium handles and a Reeve Integral Lock keeps the design streamlined and simple.

The gently curving and elegant design is by the Polish custom knifemaker Marcin Slysz.

Being a Spyderco, we have a Spyderco wire pocket clip. This can be fitted to either side of the knife for a tip-up carry.

The alternate clip position with blanking screw. If you swap the clip side, you need to swap the screws round as they are different lengths. The Lanyard hole is lined to make it easy to fit cord through both sides of the handle.

A 12mm opening hole is comfortable to use for right-handers and has a nice cut-out in the handle to give easy access, but as you can see, the reverse of the hole is partially blocked by the lock bar, so this is not ideal for left-handers.

Details ‘make’ designs, and in this example, the finger guard formed by the handle titanium, and the spine of the blade have been positioned such that they line up when the blade is closed, keeping the outline of the closed knife smooth and tidy.

To make the SpydieChef easy to clean, small spacers have been used to give as much access as possible into the handle.

Here I’m showing two specific details of the lock-bar spring, the first is the thinning of the handle scale to reduce the spring tension, and the second is the stress-reducer hole drilled at the end of the lock-bar slot.

Similarly there is a stress-reducer hole drilled at the corner of the lock-bar cut out in the titanium scale.

Here the blade is in the closed position sitting against the stop pin. There is also a hint of that phosphor-bronze washer.

Lock engagement is excellent, with room to move as the lock wears, but with a positive overlap which won’t slip out under pressure or if knocked.

The open blade sitting onto the stop pin.

Though compact enough to fit into a folding pocket knife the Marcin Slysz blade design is immediately reminiscent of a kitchen knife. Marcin Slysz’s logo is included on this side of the blade.

The other side of the blade has the Spyderco branding as well as the steel specification.

Flowing lines sweep the blade tip nicely into the handles in the folded position.

A closer look at the blade tip. Note that the entire blade spine has had the edges eased so they are very slightly radiused and smooth.

What it is like to use?

We’ve had a good look round this knife, but what really counts is how it is to use and cut with. Take a special purpose knife and make it into a folder and you immediately introduce compromises, so this was always going to be a challenging design to get right. Also considering that the chef’s knife, by the very nature of being taken out of the kitchen and put into your pocket as an EDC blade, will now be used for so much more than just kitchen duties, so some compromises have to be made.

I’ve used other folding kitchen knives, and after considerable use and comparison, I’ve found the only advantage they had over the SpydieChef was a thinner blade. A thinner blade which only gave a slight advantage on a chopping board in a kitchen, and in no other situation when carrying the knife as an EDC blade. The thinner blade always flexed far too much for EDC tasks and become more of a liability than an benefit.

Before we look further at the SpydieChef in use, to give an idea of scale, here it is next to the Fällkniven F1 and a Spyderco UK Pen Knife. It is a very pocketable size knife which is helped by the slim profile, but has enough blade to be useful. Clearly you will struggle to chop large vegetables with this knife, but it is an EDC folder and not a substitute for a full sized Chef’s knife.

Something I do want to mention is that Spyderco definitely get the blade retention detent resistance right. The reason for mentioning this is that I’ve come across certain knives with integral locks where the detent is far too stiff and should you touch the lock bar when trying to open the blade you have had it, the blade is virtually locked in place – not so with the SpydieChef. The blade is perfectly secure in the closed position, so let’s get that clear, but then regardless of how you hold it, fingers on the lock bar or not, the blade opens with a slight resistance that is easily overcome with the 12mm opening hole. I don’t want to be thinking about how I have to hold a folded knife to open it (beyond the basics of which way the blade swings open), so this is a major factor and over stiff detents on integral locks have ruined otherwise good knives. Spyderco have consistently got this right and in this case I nearly forgot to mention it as I hadn’t noticed any issues or hang-ups opening this knife, so it went out of my mind.

Slim, flat slab handles can often become uncomfortable in use quite quickly, but their low profile makes them easy to carry. However, the curving handle of the SpydieChef does a very good job of resting over your fingers and sitting into your hand in a perfectly comfortable way despite its slim flat profile.

The SpydieChef sitting comfortably in my hand (XL glove size) with my forefinger nestled up to the integral finger guard.

Absolutely crucial for a kitchen knife is it ability to be used cutting down onto a chopping board. This requires clearance for the fingers when the edge is in contact with the board. As well as the clearance, it helps cutting control enormously to have a curved edge that allows you to rock the blade for fine chopping or to apply controlled cutting force to harder foods like nuts while keeping the edge in contact with the board. The geometry of the SpydieChef has this absolutely nailed, and I’ve been chopping away without rapping my knuckles and no food pinging off the board.

I mentioned it earlier, compared to an actual kitchen knife, the blade is thicker (an EDC compromise) and this does mean that the knife does not fall through firmer and larger vegetables like a thinner blade does. Instead you can get that slight snapping action at the end of the cut, but the full flat grind does a good job of parting the cut, and these crisp chestnut mushrooms which can be quite fragile and break up with wider blades have stayed in nice slices without cracking or other signs of stress.

It might not really be much of a challenge for a knife, but the combination of a tough skin and the soft flesh means a less than capable knife can make a real mess of an avocado, but not in this case where the only limit was user skill.

Breakfast is served…

In terms of kitchen capabilities, the fact I can pull this from my pocket and work with it happily, and at the same time not worry about any residues making their way into the handle or pivot, makes this a huge winner for those days when food prep is a big priority; holidays, camping, picnics, workplaces and more.

With the ultra-corrosion-resistant nitrogen-based LC200N blade, phosphor bronze washers and titanium handle, the SpydieChef doesn’t mind getting dirty, being exposed to corrosive juices and otherwise being left to marinade with the rest of the cooking. You can even pop it in the dishwasher for cleanup afterwards.

Where the SpydieChef gives you extra, is that it is capable of so much more than the light cutting duties of just food prep. The blade is thick enough for you to really grab a handful of that handle and put it to some hard work on tougher materials (and the LC200N will keep its edge longer than an H1 blade will). Mixing it up between food and non-food use might mean a few washes or wipes in between, but this single knife can do it all.

I’ve always been a fan of the kitchen knife as a general purpose blade and have carried both modified and unmodified chef’s knives into the field, so personally I find the SpydieChef’s style and shape ideal as an EDC blade.

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.

Gear Review: Wicked Edge ‘Field and Sport’ Sharpener

Wicked Edge’s sharpening systems have proven themselves over and over to be the ultimate precision guided knife sharpeners on the market, so much so, many high-end knife makers use them for their knives’ first edge, rather than hand sharpening their blades. Wicked Edge sharpeners are solid, reliable and fast. If you want the most precise and repeatable edge possible, combined with the least blade wear, choosing one of these sharpeners is really the best possible choice you could make.

A little more Background:

In the world of knives, Wicked Edge is one of those aspirational products. Almost everyone wants one, but few people feel they can justify paying the relatively high cost of one. Much like any quality ‘professional tool’ that performs to a higher standard, most people simply do not NEED them. Simpler, cheaper options exist, and do a reasonable job.

Perhaps one of the other challenging aspects of making that leap into the realm of the Wicked Edge is that most often we see the famous mirror polished hair splitting Wicked Edge (which I too started this article with), and to achieve this you need the full set of stone grits and strops. But you don’t need to go that far, or spend that much, certainly not straight away.

The Field and Sport is one of those simpler systems on offer which includes four grits, 100, 200, 400 and 600, and is also designed to be portable and easy to set up. In real terms, the 600 grit will give you a better working edge than a finely polished mirror finish anyway.

For this review, Wicked Edge did send a few extras as well to allow me to show the finer finishes, but they are not needed for Wickedly sharp knives.

A few more details:

As the Field and Sport is a portable model, it comes in a carry case. This is useful for storage as well as taking it with you. Also shown here is a box of the optional glass platens for using the diamond polishing films.

Opening up the case everything is nicely laid out in a closed-cell foam liner.

Looking a little closer you can also see that in this case the optional extra fine 800/1000 stones have been included which are not part of the standard Field and Sport kit.

To be clear, this is the full set of part of the 2016 version of the Field and Sport kit. Included are the blade clamp, g-clamp, guide rods, 100/200 and 400/600 stones, Allen keys, blade stop and marker pen.

Adding in the optional 800/1000 stones that also fit into the case makes the kit look like this.

Although not clamped onto a working surface, this is the Wicked Edge fully assembled with the blade clamp, guides and stones ready to work.

With a knife fitted securely into the blade clamp this shows the arrangement of the stones as you work on the knife.

Most guided systems use just that, guides. I make that distinction as less robust guides can be bent and distorted. Not so with Wicked Edge. Take a look here at the guide rod ball-joints which have smooth but play-free movement.

The rods fit through the entire length of the stones providing a stable alignment.

You can go precision crazy with the adjustments on the guide rod mounts. There are two hand-wheels, the lower one does the main angle adjustment.

The upper hand-wheel locks the fine angle adjustment, and once released you can turn the ball joint bolt and move this out by any amount and lock it in place.

That lower hand-wheel locks into a series of precisely positioned angle holes cut into the guide rod arms.

As you can see, the hole’s spacing changes as you get further from the middle to keep the change in angle consistent for each graduation. If this was not done, when you get to wider angles each adjustment would become a smaller and smaller fraction of a degree.

This version is the 2016 version of the blade clamp, but the principles should be similar for the latest version. One part of the clamp is fixed to the base.

To allow you to fit each blade into the clamp in the same position each time (to reduce the amount of metal removed when you re-sharpen it) there is a folding ruler inside the clamp.

The ruler in the extended position.

You might have notice the set of four holes near the top of the blade clamp. These provide two blade heights that are set by a removable dual pin that you rest the spine of the blade on as you tighten the clamp.

Tightening the clamp is a two stage process where initially you tighten the top bolt.

Then move the Allen key down to the lower bolt and tighten this to bring the clamp plate back out to a parallel position (to stop the blade popping out). This is important or you will have blade instability when sharpening.

Once the clamp is properly tightened you need to remove the blade height stop pin.

With the stop pin removed you will have room to work on the blade.

Altogether the Field and Sport has four grits, 100, 200, 400 and 600, and here I also have the 800/1000 stones. The following series of photos is intended to show how those grits compare from most coarse to least.

What it is like to use?

This review has taken a while as even a ‘normal’ reviewer doesn’t sharpen knives at the same rate as a professional knife maker, or knife sharpener. What you will also find is that the Wicked Edge takes time to wear in and actually improves over time. Wicked Edge even recommend you start using it on a few ‘inexpensive knives’ first.

During the coarse of this review testing I’ve used the Wicked Edge on all sorts of blades, and in this next sequence is actually a titanium diving knife. Titanium is notoriously difficult to get a good edge on, but you would never know it, I didn’t do anything different and it was a super slicer at the end of this re-profile.

This blunt tip diving knife has had the left edge re-profiled and the right has not yet been done. We will step though the process…

I’ve taken to putting masking tape onto the blade before fitting to the clamp to ensure there are no marks left. This can lead to some movement depending on how thick and soft the tape is, so be careful with the tape you choose and see if this works for you or not. For some blades I don’t do this.

There are plenty of videos showing the Wicked Edge sharpening action. It is a two handed process where you push the stones away from the edge and away from you stroking the entire edge, first one side, then the other. The speed you work will depend on how practiced you are, and how precisely you want to work (and how much material needs to be removed). I also worked the stones up and down when I had a lot of material to remove.

An interesting point to note is that unlike just about every other sharpening system, due to the ability to immediately alternate sides, when doing this, you won’t raise a wire edge. The only way to do this is to stop the alternating action and just work on one side at a time until you have achieved the burr/wire-edge, then swap to do the same for the other side before getting going with the alternating action and working through the grits.

The 100 grit leaves a very clear scratch pattern, and you can see I’ve worked it up and down here as the scratches are at two angles. This was a reprofile so needed a lot of work.

Starting to work out the 100grit scratches with the 200 grit, but some scratches are pretty deep. This is one of the ‘features’ of the new stones, they can have some hot spots which create deeper scratches. Only when really worn-in are these avoided.

Just keep refining through the grits. The precision of the guide system just makes a beautiful edge appear before your eyes. For this blade I did not want to polish the edge as I wanted some bite and micro-serrations, so stopped here at the 600 grit.

Now changing blades and onto a large CRKT folder which needed a re-profile. Here you can see how I’ve used the marker pen to blacken the original edge so I can see when I’ve completely removed it and achieved the angle I want.

In this case the intention was to get to a polished edge…. just because, OK. So here we have the glass platens onto which you stick the diamond films.

The platens have Fine and Coarse marked on them, but this is for your reference and to tell you which side to fit the different diamond grits, not because like this there is any difference.

The Diamond films are simply peeled off the sheets and stuck onto the platens ready to be used as the final stage. These films cut fast and will get dirty pretty quickly. Kyle of Wicked Edge showed me a nice trick for cleaning these up with a bit of alcohol hand rub on some tissue which brought them back to life and gave them a new lease of life, so don’t give up on them too quickly.
NOTE, unlike the diamond stones which can be used onto or off the edge, you MUST use the diamond films OFF the edge otherwise the edge can bite into the film and ruin it – just like any other strop.

What becomes really obvious at this point are two aspects. The first is that the brand new stones make it much more difficult to properly work through the grits and remove the scratches from the coarser grits, and the second is that this will really show you up if you haven’t worked through the grits well enough!! Lessons get learnt.

Ultimately we get there though, and the Wicked Edge precision mirror edge is mine – ALL MINE!

Light Review: FOURSEVENS Preon P1 Copper Limited Edition

FOURSEVENS’ Preons have been very popular and well regarded AAA powered EDC lights. After their latest reboot (previously reviewed), this is the special edition solid copper version. Grab one while you can here and don’t miss out on the copper goodness.

Taking a more detailed look:

Unlike the standard edition Preons, the Copper version does not come in a clear plastic box, instead it comes in a presentation cardboard box.

The contents are nicely laid out.

Included are the Copper Preon P1 (in a protective plastic case), a Duracell AAA cell, and the instructions. That plastic protector is to ensure that the Copper P1 arrives while still a Copper colour. The patina and darkening can then develop over time as you use it.

The Copper Preon is exactly the same in design, dimensions and machining as the standard P1, just made of solid Copper instead of aluminium.

Every part that was aluminium in the standard version is Copper, including the switch button cap.

Taking a closer look at the bare Copper machined surface.

With the small reflector and XP-L LED, the Preon P1 is set for an excellent EDC beam.

The XP-L LED and textured reflector.

With the head removed (for inserting the battery) the contacts can be seen.

The threads are standard and cleanly cut.

Shining another Preon down the battery tube allows us to see the negative spring contact.

FOURSEVEN’s logo is engraved on the switch button cap.

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 with the P1, it has plenty of power for your close range EDC needs, with a nice wide, soft, hotspot and wide spill.

At outdoor ranges the Preon struggles as it is only a single AAA powered light and has a flood orientated beam. These exposures are long to show anything. The P1 doesn’t have much impact.

Modes and User Interface:

Just as with both the standard Preon P1 and P2, the special edition Copper P1 operates in the same way with a forward-clicky switch.
In total, there are 7 output modes which can be used – Low, Medium, High, Strobe, SOS, Beacon (high), Beacon (low).

To fine tune the Preon to your needs, you can set one of 5 possible ‘Configurations’ which have only certain modes available:
Configuration 1: High
Configuration 2: Previous, High, Low
Configuration 3: Previous, High, Strobe
Configuration 4: Previous, Low, Medium, High, Strobe
Configuration 5: Previous, Low, Medium, High, Strobe, SOS, Beacon (high), Beacon (low)

By default, configuration 2 is set. To change configuration, rapidly press the switch 10 times within 2s, holding or clicking the tenth press.
At this point the Preon will flash 1 to 5 times to indicate the selected configuration.
Quickly turn the Preon OFF and ON again to move to the next configuration, and repeat until you have the desired configuration. To memorise the setting, turn the Preon OFF for 5 seconds.

The Preon has a memory of the last mode used. This is relevant only on Configurations 2, 3, 4 and 5.
To change to the next mode in the chosen configuration, turn the Preon OFF and ON again within one second.
As shown in the Configuration list above, when you first turn the Preon ON, you get the ‘previously used’ output mode. When you then change mode, you jump to the start of the set of modes for that Configuration.
For example, if you are set to Configuration 5 and previously used Strobe, when you first turn the Preon ON you get Strobe, and when changing modes the next mode becomes Low, Medium… (In this example you do not go to SOS as the next mode).

Batteries and output:

The Preon P1 runs on AAA Alkaline or NiMh.

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.

___________________________________________ ________________________________ ________________________________
Preon P1 Cu using specified cell I.S. measured ANSI output Lumens PWM frequency or Strobe frequency (Hz)
___________________________________________ ________________________________ ________________________________
High 97 1000
Medium 50 1000
Low 7 1000

* 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 200 lx @1m giving a beam range of 28 m.

There is no parasitic drain.

The Preon P1 Cu exhibits the FOURSEVENS ‘Burst Mode’ behaviour. When on maximum output the first three minutes are at a higher output before dropping to a slightly lower level for the remainder of the 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 FOURSEVENS Preon P1 Copper in use

If you have read my other Preon review, then this will be mostly the same as the light is the FOURSEVENS Preon, just in a lovely raw Copper. I’m including the impressions of the current Preon as they are just as relevant to this special edition as the standard ones.

When compared to the previous generation Preons, these new versions are slightly chunkier, and initially I was not entirely convinced, as the point of an AAA light is to be very small. But then I remembered that as much as I love the older Preons they were always a bit slippery. The smooth body wanting to slide around and not giving much of a grip.

With the new Preons having a grip pattern over the entire length of the light, no longer do you get this slippery feeling. One further observation though, is that these grooves tend to pick up pocket fluff nicely, which does somewhat spoil the look.

Personally I preferred the previous UI where it had no memory, but for some a memory is a requirement as you can pre-select the output you generally use. However, as the memory only affects the mode at switch-on, after which the mode selection goes to the first of the modes in the current Configuration, it only takes one mode change to return to Low.

Unfortunately another aspect has changed in the new version, PWM is rearing its head. The previous Preons had PWM but at 2500Hz and was not noticeable to the naked eye; the new version has PWM at 1000Hz. On High and Medium this has not really been visible, but on Low, I do catch the strobing effect out of the corner of my eye. A minor irritation and not what I would expect of FOURSEVENS. It slightly takes the edge off what could be a great update to this well loved series.

It used to be more common for smaller EDC lights to go with a reverse-clicky switch, but as in earlier versions, the Preon does use a forward-clicky and gives you that immediate response to pressure on the switch.

A great feature that has been added to the Preons is the user-changeable configuration that allows you to limit which output modes can be selected. You don’t get to choose which modes are included in a ‘configuration’ but you can choose one of the five available ‘configurations’ to best suit your needs. This user configuration has great potential and I hope FOURSEVENS expand the number of configurations that can be chosen from.

With the small power source of AAA, the added efficiency of the XP-L (though only around 9%) makes a difference. Thanks to the XP-L having an XM-L2 size die in a smaller package, it is compact enough to be fitted into the Preon’s head and provide a great EDC beam.

The new Preon doesn’t just have a new body design, it has user-configuration and an XP-L LED, and in this special edition version you have a solid Copper body that with age and develop it own unique and attractive patina.

Review Summary

_______________________________________________ _______________________________________________
Things I like What doesn’t work so well for me
_______________________________________________ _______________________________________________
It’s Solid Copper. PWM at 1000Hz giving some strobe effects on low.
XP-L LED in a truly pocket-sized light. Copper marks easily and tarnishes.
User configurable. Copper is heavier.
Great EDC beam.

Knife Review: Morakniv Eldris with Fire Starter

In the third of a series of reviews looking at Morakniv’s latest models, we meet the Eldris, a fixed blade knife that is so easy to carry, Morakniv call it their ‘folding knife’.

 photo 11 Eldris full unsheathed P1240579.jpg

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 23 Eldris grind P1250028.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 22 Eldris bevel P1250024.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 21 Eldris balance P1250021.jpg

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

The blade is made from 12C27 Swedish Steel.

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 with ‘Head of Production’ at Morakniv, Thomas Eriksson, from IWA 2017 by Tactical Reviews.
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 name that tells a story – Eldris…

The traditional summer grazing land (‘fäbodar’) for the village on the opposite bank of the river from the Morakniv factory is named Eldris. During the summer time the people from the village lived on the ‘fäbod’ and used only what nature had to offer.

“To name our pocket size knife Eldris after the place and the people who lived there is our way of paying tribute to our roots. Our ancestors and the surroundings of Mora are all parts of who we at Morakniv are today. The Eldris knife – the flexible companion when doing everything from crafting to lighting the evening fire – is our interpretation of the life once lived at the ’fäbod’ of Eldris.”

“The Eldris knife has been in our minds for a long time, the small knife that fits easily in your pocket or hanging around your neck. Most times the modern outdoor life doesn’t need much more than this knife. You could say that this is our interpretation of the folding knives that are very popular today, but Eldris has the advantages of the rigid features of a fixed blade” – Arvid Larsson, Design Engineer.

 photo 18 Eldris fan P1250008.jpg

“The colours of Eldris are inspired by our surrounding region and our history. The black of coal is never far away if you go out in the forests around Mora. Suddenly you’ll happen upon an old charcoal pit or the remains of one. The well-known Dala red (or Falu red) colour gets its pigments from the Falu copper mines. Since as far back as the 1700s, the familiar red-painted houses with white frames have spread across the country and become an international symbol for Sweden and the county of Dalarna.
As well as the Dala red colour, we also have a Dala blue, which can be seen on everything from building details to clothes. It’s even in our regional coat of arms, together with the crossed arrows and the royal crown. The moss green colour is inspired by the nature and unique surroundings of the area around Lake Siljan. Deep in the forests we find the calm and inspiration for this green hue. Finally, we have the golden ocher colour, taken from the Dalarna paintings of the 1600’s, and also the folk costumes that people in Mora have worn since time immemorial.”

 photo 20 Eldris fan P1250014.jpg

A few more details:

The five different colours of the Eldris. The fire-starter optional kit is attached to the bottom of Eldris knife box.
 photo 01 Eldris boxed set P1240528.jpg

For the fire-starter kit version of the Eldris, this is the full set of components. The Eldris knife and sheath, security strap, length of cord and ferrocerium rod with leather tab and cord loop.
 photo 02 Eldris box contents P1240549.jpg

As the bare knife and sheath, the Eldris becomes a pocket knife, small and streamlined and easy to pop in a pocket.
 photo 03 Eldris basic P1240551.jpg

Moulded into the sheath are the Morakniv logo and crossed arrows of the Swedish province Dalarna.
 photo 04 Eldris logo P1240552.jpg

On the back of the sheath are the hollows for the security strap ring to clip into.
 photo 05 Eldris made in P1240556.jpg

The security strap consists of a plastic ring which clicks into place on the sheath with a leather strap that uses a press stud to secure the strap in place.
 photo 06 Eldris lock strap P1240557.jpg

Looking inside the security strap ring, you can se the lugs that click into place in the corresponding hollows on the sheath.
 photo 07 Eldris lock strap inside P1240560.jpg

Adding the security strap adds very little bulk to the Eldris.
 photo 08 Eldris lock strap fitted P1240568.jpg

At the tip of the sheath are two holes which can be used for fitting the neck lanyard and also act as drainage holes.
 photo 09 Eldris sheath holes P1240571.jpg

For use as a pendant knife you can also fit the fire-rod onto the neck cord.
 photo 10 Eldris full sheathed P1240577.jpg

The Eldris is a small knife and being a fixed blade is more reminiscent of a wood carver’s tool.
 photo 13 Eldris in hand P1240589.jpg

However, you can get a strong grip on it thanks to the handle still having enough bulk (unlike most pendant/neck knives).
 photo 14 Eldris in fist P1240594.jpg

Full Scandi-grind blades are often not so good for slicing due to the full blade thickness being maintained for the majority of the blade depth. In the Eldris, similar to Morakniv’s Kansbol, there is additional profiling for the front half of the blade which thins down the blade making it a better slicer. As a super compact all-rounder, it really helps that Morakniv have included this extra profiling.
 photo 16 Eldris blade P1240604.jpg

Also note, the factory edge micro-bevel which is described in the video.
 photo 15 Eldris blade P1240598.jpg

There is no choil or ricasso, with the blade edge going all the way into the handle.
 photo 17 Eldris handle blade P1240605.jpg

What it is like to use?

The principle that Morakniv have aimed for with the Eldris is to bring together the features and advantages of a pocket size knife but with a fixed blade instead of a folding one. A smaller knife is not only easier to carry, but gives you increased control when using it, and is safer to handle than a larger one.

By choosing a fixed blade, the design is more durable and better suited to rough use than a folding knife. Yet when the knife is sheathed, it is still small enough to be easily carried in a pocket.

It is no surprise that the Eldris features a Scandi-grind, and this makes it well suited to working with wood as well as making it easy to keep sharp. Having given the Eldris a good workout, here I’ve given it a quick touch up on a stone and then a strop.

 photo 25 Eldris sharpened.jpg

After the quick maintenance, it was falling through paper.
 photo 26 Eldris sharpness.jpg

In the case of the Eldris Fire Starter Kit, a fire-rod is included. Of course you can provide your own fire-rod and just make use of the ground spine which has sharp corners and is ideal for striking sparks from the ferro-rod. No need to carry a separate striker or (horror) use the edge to strike sparks.

There is one design aspect we must dwell on; the handle. The symmetrical handle makes this an ambidextrous knife as it allows a two-way fit into the sheath. The drop-shaped design is big enough to keep the knife securely in your hand yet allows you to move your hand around on the handle for many different kinds of grip. The outer part of the grip is TPE, a rubbery polymer that provides a secure grip, and the core of the handle is made of much tougher polypropylene. Morakniv are very proud of their heritage and express this in aspects of the design. In this case, the rhombus pattern is a traditional pattern used in Mora and the region of Dalarna, and as well as helping with grip, it also pays a tribute to Morakniv’s region and history.

Having seen very early versions of the Eldris where the click-lock had not been finalised, the final level of sheath retention Morakniv have built into the Eldris is excellent, and is very unlikely to come loose by accident. However, especially for when wearing inverted around your neck, the secondary locking strap absolutely prevents the knife from falling out of the sheath. When carrying in your pocket or a bag, you might not want the secondary lock and the plastic collar can be removed, making the Eldris even more compact.

Knives this compact and light are generally only suited to very light tasks with handles that can’t be used for long before they become fatiguing or painful. The Eldris has a big enough handle that you can get a strong grip, a grip which you can work with for longer periods. Combining this usable handle with a blade length that is sufficient for most typical cutting tasks, and it gives you a really easy to carry fixed-blade pocket knife.

 photo 24 Eldris bark P1250229.jpg

I would not go so far as to call it a folding knife, but it really is a pocket knife – with a fixed blade.

We can love blades of all sizes, and I can’t resist the biggest of blades, but taking into account your actual needs and the ‘cost’ of the weight you have to carry with larger blades, the Eldris makes a huge amount of sense.

Unless you are doing some heavy chopping or batoning, the part of the cutting edge you are likely to use the most, is that part you can apply maximum pressure to – the section of blade closest to the handle. This is exactly what the Eldris has.

Never a fan of the ‘neck knife’ (nor of the term), the Eldris has won me over and become a regular companion, frequently round my neck!

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.

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.

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.
