Showcase: Spyderco Shaman – The knife that nearly passed me by

While the latest ‘stand-out’ designs compete for our attention, often it is the quiet ones you need to look out for, and for me, this is what the Spyderco Shaman is. I very nearly passed this by while at IWA 2018 as it is a plain looking knife with stonewashed blade and matt handle – nothing exciting. Well thanks to Joyce at Spyderco, I didn’t miss out on this fantastic knife that nearly flew under the radar. This is not just a bigger ‘Native’, it is much more than that.

Gallery:

A quick note before you dive into the gallery; look out for the excellent ergonomics – with the Shaman, Spyderco have rounded all the handle edges of the matt finish G-10 handles, and this makes for a completely different feel for the knife, almost getting on for the feeling of a fixed blade. The compression lock keeps the lock out of the way of the grip nicely, and the finger choil and thumb jimping give a super secure grip. This one just feels right in the hand and pocket.

BESS Certified sharpness testing:

Before we get to the photos, also included in this showcase are the results of the factory edge sharpness testing. These are impressive results; see the gallery for the certificates.

The BESS ‘C’ scale of sharpness, was developed by Mike Brubacher (Brubacher Edge Sharpness Scale).

 
The Shaman’s factory edge has an average BESS ‘C’ sharpness of 211. At this sharpness it easily and cleanly slices 80gsm copier paper, and will shave hair from your arm. Spyderco reliably supply very sharp factory edges, and this, though not the best, is at the sharpness I would aim to re-sharpen a knife to, so more than adequate.

Don’t let the Spyderco Shaman pass you by, it is much more knife than its unassuming looks might indicate.

Performance Review: Emisar D4 – Quad Nichia 219C LED Light

The Emisar D4, made by Hank Wang of Intl-Outdoor, is one of those lights that has created such a stir with its stunning output levels, that if you haven’t come across it yet, you will do. Hank has created a light by which others will be judged and at an amazingly low price. Coming in several flavours of LED, with varying maximum output levels, the light on test here is the Neutral White 90CRI Nichia 219CT LED version. Also included with this review sample is the 18350 tube allowing it to be used with 18350 and 16340 cells.

Taking a more detailed look:

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!
 

 

Modes and User Interface:

From OFF:
1 Click – Turn ON to memorised level.
Press and Hold – Turn ON to minimum and Ramp up.
2 Clicks – Turn ON to Max output.
3 Clicks – Enter Voltage Battery Check (longer flash indicates a 1, short flash indicates a 0. Whole Volts first, then tenths).
From Voltage Battery Check 2 Clicks to enter Temperature Check (longer flash indicates a 1, short flash indicates a 0. Tens of Degrees C first, then Ones)
4 Clicks – Set to use Tactical (Max output) Momentary mode. 4 Clicks to cancel this mode.
6 Clicks – Lockout. 6 Clicks to cancel.
8 Clicks – Beacon Mode
10+ Clicks and hold – Thermal configuration. Hold the button until the D4 is as hot as you want it to get.
When ON press and hold to ramp up or down in output.

Batteries and output:

The Emisar D4 runs on several cell types depending on the battery tube you buy. In this case there is the 18650 tube and the 18350 which also allows a 16340 to be used. Only IMR cells should be used in this high performance light and a 20A output should be considered a minimum.

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.

There is parasitic drain. When using 18650, the drain was 22.6uA (15.65 years to drain the cells). On Lockout, the drain was 25uA (14.15 years to drain the cells).

Below is the combined runtime graph for all the types of test carried out. It includes the D4 being run in its factory thermal configuration (45°C), and then the thermal configuration taken to the max. To set the thermal configuration as high as possible, it was set while wearing kelvar gloves (the bezel reached 80°C when setting this). Tests were carried out with fan cooling.
 

This gallery contains the other versions of the runtime graphs.

Knife Review: Hinderer Knives XM-Slippy

Hinderer Knives’ XM-Slippy was designed to answer the high demand from the European market for a Rick Hinderer knife that could be carried in areas with more restrictive knife carry laws; as its name suggests, it is a slip-joint knife. The knife was debuted at IWA 2017 and is currently entering into its second production run. The XM-Slippy shown in this review is a first run knife and externally there is no visible change when compared to the second run. Designed to be as universally EDC legal as possible, the thumb disc can easily be removed for two-handed opening if required.

New Review Format 2018!

Tactical Reviews is known for very detailed reviews using many high quality images. This has meant quite a lot of scrolling to read most reviews. In the new format, the review contains ‘responsive image galleries’ to better display these images as a slide show with captions.
NOTE: On a PC it is best to use the arrow keys to move through the images. Captions can be hidden by clicking the small ‘x’ in the caption box. To enable them again, close the gallery and reopen it.

A few more details:

What’s in the box?:


A good look round the XM-Slippy – Things to look out for here are:

This example has the VERY orange G10 handles, but the XM-Slippy is also available in much more neutral colours. The stonewashed steel pocket clip is fitted by default in the tip down position and is pretty thick and sturdy (also read ‘stiff’).
One design aspect needs a little more attention; the smoothing/easing of all edges. A very obvious example of this are the edges of the back-spring, and the bevelled edges provide shadow lines along the back of the handle. The fact all edges are eased/rounded gives it a distinct look and feel and a great comfort in the hand and pocket. Some might criticise the fact that the H doesn’t look as tight as they would expect, but this is as it should be; the combination of the easing and the fact there is an internal stop-pin results in this appearance, the blade itself is spot on and perfectly positioned.
Peering into the liners, you can see the very end of the clip screws just coming through the liner, but there is no contact with the blade; it does mean the screws are as stable as they possibly could be as they fill the threaded hole completely.


Rick Hinderer’s Thumb Disc:

The Hinderer adjustable thumb disc uses a small grub screw (0.035″ Allen key) to secure it in place. The Thumb Disc channel is the same on both sides of the CPM20CV blade, forming a T-shaped section that the thumb disc slides onto. The thumb disc can be positioned anywhere along the channel, or removed, allowing the user to find the best location for them.


The XM-Slippy with Thumb Disc removed:

If you need to disable OHO or prefer the look without the thumb disc you have the choice as the thumb disc can be completely removed.
The thumb disc slot also acts like a large nail-nick giving you something to grip to open the blade.

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.

While at IWA 2018 I had the good fortune to be able to talk to Rick Hinderer about this knife.

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 CPM20CV steel.

New for 2018! BESS Certified sharpness testing:

The BESS ‘C’ scale of sharpness, developed by Mike Brubacher (Brubacher Edge Sharpness Scale) will now become part of Tactical Reviews’ knife testing process. Initially this will be used to verify the sharpness of the factory edge and allow the knife to be brought to a minimum standard sharpness before testing a blade’s cutting performance.

The XM-Slippy’s factory edge has an average BESS ‘C’ sharpness of 399. This was a show exhibit knife, so I would not comment on the absolute sharpness after all the handling and trying out it has had. As it was, the edge didn’t appear to have any rolling or damage, and with this edge would slice 80gsm well enough although not the cleanest of cut.
For testing I have taken the edge to a 30 degree inclusive angle and a BESS score of 200, at which point it is shaving arm hair with ease.

What it is like to use?

Colour is a matter of taste, and for me the Orange is perfect. I like to see where I’ve put down important tools, or worst case dropped/lost, but moving beyond the Oranginess…
There is a finesse to the overall finish which starts to sink in the more you use it. The XM-SLippy, has only one sharp edge, exactly where it should be. All the other corners are smoothed so that nothing catches on your hands, gloves or pockets. I cannot stress enough how much this adds to the quality feel as nothing ‘jars’ while you handle or use it. Some knives have an unrelenting crispness to their finish and this can mean that edges are sharp, the corners of liners, blade stop, back-spring etc, all of which can become fatiguing to your hands and pockets – not so with the XM-Slippy.
Many slip-joints use a half-stop position for the blade, and in a two handed opener I don’t object to this, but for a one-handed-opener, I find this a big no-no. The XM-Slippy has no half-stop, so the blade swings out smoothly all the way to snap into the open position without interruption. In my view this is exactly as it should be for a OHO, slip-joint or not. There are some that argue that the half-stop add to the safety in case of accidental closing, so the blade doesn’t close on your fingers. I’d counter that by saying that if your slip-joint is closing on you, you are not using it correctly, and if you have sufficient force to start closing the blade onto your fingers it is quite likely to keep going through a half-stop anyway. Rick has definitely got this right.
A design feature shown in the gallery is the relatively large choil. This is not really a finger choil, though can be used as such carefully, and it is too large for a sharpening choil. Instead its design purpose is so that if the blade is closed onto your fingers, it is the choil that actually hits your finger (see gallery) giving you some protection from injury.
Being based on the XM platform, the look is of course familiar, but it also includes some jimping which might be a little overkill for a slip-joint. The forward thumb grip is useful, but clearly when applying a lot of force with a slip-joint you need to be careful. There is jimping for a reverse grip and I’d say it is wholly unsuitable to use a slip-joint with a reverse grip, so don’t take its presence as a suggestion to use the XM-Slippy like this.
Rick has designed in easy user customisation for the XM-Slippy; starting with the pocket clip, which has two options, tip-up or tip-down. Keeping the refined finish complete, there is a blanking plate to fill in the alternate clip position, and swapping the pocket clip position is nice and easy. Using a standard Phillips screwdriver, simply undo the two screws holding the pocket clip and the two holding the blanking plate. Swap round and replace the screws…but wait, there is the next part. With the pocket clip off the knife, there is only a single screw holding the handle scale on. Take out that last screw and the G10 scale can be lifted off. Its fit is beautifully precise. A nice feature when swapping the handle scales is that with the scale removed, the knife is still fully functional, as the liners are held together with other fixings.
This example is fitted with the Hinderer ‘slicer’ blade which is an excellent general purpose blade shape for an EDC knife.
Is the adjustable thumb disc a gimmick? Maybe, maybe not. Though I can never see the extreme positions you could put the disc being used by anyone, the length of the thumb disc slot looks right for the proportions of the blade. Even small adjustments can make a big difference for your experience of using the knife, so don’t be afraid to move it about and try. I’ve settled on a position that is different to all my other knives with thumb stud /disc. Then of course you can take it off, if you are visiting an area where the law does not permit one-handed-opening. I have found the thumb disc slot does collect a bit of pocket dust, but nothing compared to a pivot or the handles, so not to worry, and anything other than a perfectly plain blade will fail the ‘peanut butter’ test anyway.
The factory/show edge needed attention before I started to really use it, and the CPM20CV proved to be very easy to sharpen and took a razor edge with very little work. My current sharpening method is to use a small belt sander (120 grit with a light touch) with bevel angle guide to reprofile to 15 degrees per side followed by a good stropping with a polishing compound, the edge on this blade simply wanted to be super sharp.

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.

_______________________________________________ _______________________________________________
Things I like What doesn’t work so well for me
_______________________________________________ _______________________________________________
High quality fit and finish. Expensive when compared to most slip-joint knives.
Adjustable / removable thumb disc. Pocket clip a bit tight for my taste.
All edges smoothed making it especially hand and pocket friendly.
CPM20CV steel takes a super sharp edge (with ease – depending on your sharpener).
Pocket clip can be positioned for tip-up or tip-down use.
Simple to replace/change handle scales.

Knife Review: Pohl Force Prepper One (Tactical)

Born from key influences in Dietmar Pohl’s lifelong passion for knives, the Prepper One combines the hollow handle survival knife concept with a traditional style ‘straight’ utility knife. By using modern materials and manufacturing techniques, Dietmar Pohl has avoided all the typical weaknesses of hollow handle knives and produced a super strong design that won’t let you down. This review features the Prepper One Tactical (G10 and wood handle), but the range also includes the Prepper One Survival, and Prepper One Outdoor (plus wood handle options for these).

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.

The Prepper One’s factory edge has an average BESS ‘C’ sharpness of 345. At this sharpness it easily and cleanly slices 80gsm copier paper. It doesn’t quite want to catch a rolled edge of the same paper, but will 50% of the time.

A few more details:

The Prepper One Tactical arrived in a cardboard box.

Inside, the Prepper One was wrapped in paper (so much better than plastic).

In this case the wooden handles have also been included, but these are an optional extra. There was also a Pohl Force Patch and a certificate card.

Whipping off the paper wrap, the Prepper One arrives in its Kydex Sheath.

Let’s start off with a look round the sheath. The belt loop looks like normal nylon webbing, however, the loop is actually very stiff and holds its shape.

The Kydex lips have been shaped and finished well, so unlike many Kydex sheaths there is no additional finishing required to ensure a smooth operation.

That stiff webbing belt loop is not fitted directly to the sheath, but instead to a hanger which is then bolted onto the sheath.

Looking from the side you can see the hanger. This allows the user to adjust or remove the belt loop and use another mount system.

A drainage hole on the back of the sheath just shows the blade tip.

Kydex wraps the first quarter of the handle and keeps the Prepper One securely in place without making it too hard to remove.

Ah, now, here is something we didn’t see earlier. There is a flat ‘key’ fitted to the lanyard

This is going to give us access to the hollow handle.

Before moving on, taking a torch and peering into the sheath we can see why the Prepper One has no hint of sheath rattle, there is a flocked velvet liner which keeps the sheath nice and quiet.

And onto the knife itself…

Pohl Force’s logo is cleanly engraved on the blade and the serial number on the ricasso.

A small sharpening choil sits at the end of the radiused plunge line.

One of the large handle bolts. On this side, there is a large slot.

Pohl Force’s partner in the production of the Prepper One (amongst others) is Lionsteel, well known for their quality of manufacture.

Fitted with the original G10 handle scales, the Prepper One Tactical uses a OD Green colour.

A series of offset longitudinal grooves machined into the surface makes for a very secure grip, even in slippery conditions.

Another look at the grip texturing at the guard.

Both the tang, and handles make up the Prepper One’s guard.

Made possible by the G10 handle material, and the fact both the inner and outer surfaces need to be machined anyway, the lanyard (which passes through the full tang) is directed backwards by a groove cut into the inner surface of each handle slab. This keeps the lanyard completely away from your hand preventing any lanyard hotspots while working with the knife. A small but very useful feature.

On the back of the tang there is one more engraving.

This is a hollow handle knife, but it is also a true full-tang blade as well.

A deep section of jimping gives your thumb a comfortable and secure surface to press onto.

Niolox was chosen for its fine grain structure and super stain-resistant properties.

Taking a close look at the factory edge next to the blade tip.

With such a substantial blade stock (6mm) there is a taper to the front section of the blade to prevent the tip from ending up with a massive edge bevel.

The Key, The Secret:

No, not a nineties hit by the Urban Cookie Collective, but the Prepper One’s key to its concealed hollow handle.

Using the key to unscrew the handle bolts, and lifting off one handle reveals the hidden compartment.

This skeletonised tang, much like many full tang knives have to change the balance, provides part of the hollow compartment. The handles themselves are also milled out to make the space inside the handle larger.

Fully disassembled, we have the two G10 handles, the two parts of both handle bolts, and the full tang knife blade.

Should you wish to, perhaps if the handle scales were lost, you could use the bare knife as it is, or adding a cord wrap.

The handles with a steel ruler to show the size of the hollow compartment.

There is more.

For an even more traditional look, Pohl Force now offer a Santos wood option for the handles.

As removal and fitting of the handle scales is so easy (exactly as this is something you should be doing to access the hollow handle), swapping between the G10 and wood scales is just as easy.

The only slight complication is that the wood is not quite stable enough to use the same lanyard layout as the G10, so the cord needs to be removed and threaded through the more traditional lanyard holes used for the wood scales.

A different grip texture is also used, as the fine pattern milled into the G10 would not work in wood.

It does look good with those wooden handles.

What it is like to use?

I was fortunate enough to have the choice of testing either the Prepper One or Prepper Two. I chose the Prepper One purely for its much more general purpose size, with the Two being a much bigger camp knife. Clearly as the first of the Prepper designs to be released it needed to be versatile and easy to carry (with the added bonus relating to German knife carry law described by Dietmar in the video interview).

However much I was drawn to the Prepper Two, the Prepper One was so ‘just right’ I knew it was the right choice. Even better would be the pair.

My hands take XL Gloves, and though my fingers wrap the grip fully, it still feels a generous size for excellent stability without ending up too big for smaller hands.

You can see here I have the G10 handles fitted. For hard work they are my favourite over the wood grips, however, I love the way the wooden grips look, and really fit that traditional feel of the knife. The G10s will be the workhorse grips for me, but the wooden ones will come out when I want a different feel.

The jimping is perfectly positioned for your thumb when using a sabre grip. With its 6mm blade stock, this thumb position is very comfortable and allows you to exert high pressures without the spine cutting into your thumb.

Of course the flip-side to this is that you can never really forget about that 6mm blade stock, as the Prepper One does feel a relatively heavy knife due to this, despite the hollow handle taking a big chuck out of the weight of the tang.

We must dwell on that 6mm blade stock a little longer. What is the purpose of the Prepper One? Its name ‘Prepper’ pretty much sums it up, a knife to ensure you are prepared for whatever you might have to face. These are the situations where a knife blade might have to be used for much more than simple cutting. Breaching, demolition, splitting and use as a spear are only a few of the many extreme tasks it may be needed for. You might balk at the mention of some of those, and many less substantial knives would just fail leaving you worse off than before, but that slight weight penalty gives you a blade that has a strength that you are not ever likely to exceed – Prepper is the word indeed.

And preparing yourself further, the hollow handle…

As it comes, the key has been put onto the lanyard, which can become a little awkward. I’ve moved this around (check out @TacticalReviews on Instagram for a photo) so the key is attached to the sheath instead, with the lanyard cord on the knife left plain.

When reassembling the handles or swapping to the wooden grips, make sure to line up the flats on the handle bolts with the corresponding shaping in the holes. Failure to do this will result in the bolts sitting too high and possibly damaging the handles.

So what would you put in that hollow handle? For me it is Fire and Fish. Remember that this hollow handle is not water-tight, so whatever you put in there might get wet.

Picking a fire steel instead of matches eliminates the worry of it getting wet, and a multi-part fishing kit is going to get wet anyway.

Without even packing all the available space, I’ve got four different fishing rigs plus the firesteel.

The fishing kits are designed to cover as many options as possible and are crucially pre-tied, including loops to tether the line. Cold, wet tired hands are not the best tiers of fiddly knots. Two of the fours rigs use flies, and two have plain hooks and artificial maggots included in the kit; this way no additional bait is needed. All can be used by hand, or attached to a rudimentary rod. Note as well that each pre-tied barbed hooks has a cork protector – the last thing you need to do is hook yourself.
Braided Dyneema is used in preference to monofilament as it doesn’t take a ‘set’ in the same way, and is very abrasion resistant and strong for its diameter. Some rigs also have mini floats to either keep the line afloat or act as bite indicators.

But I digress…

The Prepper One; in reality the hollow handle is more of a fit and forget feature. The things you put in it are things you want to have and will be glad you do, but really don’t want to need. With the need to disassemble the handle it isn’t a practical every day storage solution, but is an excellent backup option.

As a knife rather than a survival tool, the Prepper One feels well balanced (if slightly heavy) and its full flat grind really helps the slicing ability of the blade, but the 6mm blade stock does make its presence known with deeper cuts in stiff materials. Though I can appreciate the benefits of Scandi-grinds, the choice of a full flat grind really suits the Prepper One, and makes it very easy to work with.

Kydex sheaths are not my favourite, mainly due to what I call ‘sheath-recoil’ where overly stiff Kydex sheaths lead to knives flying out in an uncontrolled way when unsheathing them. Not so with the Prepper One. The sheath retention is spot on, and the knife is both held securely and also perfectly easy to remove without any hint of sheath-recoil.

With its utility blade dimensions, you would not think of the Prepper One as a chopper, especially next to its bigger brother the Prepper Two, however, thanks to the 6mm blade stock it has more weight to it than most other knives this size. So you can employ this for light chopping, or just to get through smaller branches a bit quicker. Not a major feature, but helpful considering this size of knife is easy to carry.

The finger guard is not very pronounced, but it is very effective at stabilising your grip on the knife. Overall the shaping of the handle and guard make it very comfortable to use for extended periods. I have also really appreciated the way the lanyard is pushed backwards in the G10 handles, so however you hold it, you don’t end up pressing onto the lanyard cord (which can make a hotspot). Once I decided to move the hollow handle key off the lanyard (and fitted it to the sheath) the experience of using the knife became a real pleasure, and without having to carry a much bigger ‘survival’ knife, you also know you have a potential beast of a blade should you really need it. It might be named ‘Prepper’, but it is a knife you can use every day.

Light Review: Streamlight Dualie – 3AA Magnet, 2AA ATEX and Laser ATEX

Streamlight’s Dualie range are not the only dual-beam lights available, so might look familiar. The 3AA version is not new, but the 2AA ATEX and 3AA Laser ATEX are both recent additions for Streamlight, adding more options to this Intrinsically Safe range.

Taking a more detailed look at the Dualie 2AA ATEX:

We are starting with a detailed look at the 2AA ATEX version, but before we do, here are all three Dualie lights on test in this review. The 2AA model arrives in a cardboard box like the 3AA Magnet, with the 3AA Laser in a plastic blister pack.

In the 2AA’s box along with the Dualie is a set of alkaline batteries, a wrist lanyard, an Allen key and the instructions.

Immediately striking is the offset head design of the 2AA.

And this is why it is a Dualie. The flood-light LED in the side of the head.

A better look at that unusual offset battery tube. The top of the pocket clip is kept level with the line of the head of the light.

The tail has a lanyard hole, and also a magnet.

A simple, deep, steel pocket clip is fitted to the 2AA.

The main beam’s switch is the largest, and has a checkered grip pattern.

A close look at the 2AA’s main-beam reflector and LED.

The same LED is used for the side mounted flood beam without any reflector. The side beam’s switch is smaller and has no checkering.

Inside the light’s head are two contacts made from coiled wire.

The coil contacts connect to the battery positive terminal and a contact built-in to the front of the battery tube. The other metal part visible here is the locking screw to fix the head in place.

Instead of screw-threads, the 2AA uses a bayonet fixing for the head / battery tube fitting.

The batteries are now fitted into the body.

Now we see why there is an Allen key included. With the head fitted back onto the body, the locking screw can be tightened.

A requirement of certain Intrinsically Safe standards is that the batteries cannot be replaced in the hazardous environment. This is achieved by use of a locking screw to prevent the light being accidentally opened. Instead you need to use a tool to intentionally open the light.

The head is now locked and can’t be taken off without the screw being loosened.

Ready to go.

Taking a more detailed look at the Dualie 3AA Magnet:

In the 3AA Magnet’s box along with the Dualie is a set of alkaline batteries, a wrist lanyard, and the instructions.

The Dualie 3AA Magnet’s name is due to the two powerful magnets that have been added for more hands free options.

Not ATEX rated, but still intrinsically safe.

One of the magnets is in the very end of the tail which is part of the extended clip.

The other magnet is in the side of the clip.

The clip extension also acts as a hook.

The main beam’s switch is the largest of the two, and has a checkered grip pattern.

For the flood beam on the side there is a second slightly smaller switch which also has a checkered grip pattern.

Looking into the main beam’s reflector and its LED.

A full exposed LED with no reflector provides the flood beam.

To access the battery caddy, the bezel unscrews from the front of the head.

This then allows the main assembly / battery caddy to slide out of the body.

It is a self contained unit with reflector, LEDs, switches, and battery holders.

Each cell holder has spring contacts for the negative terminals.

Plus a coiled positive terminal.

Two cells are fitted to one side, and a single cell into the other.

The threads for the bezel ring are moulded plastic.

Off to work we go.

Taking a more detailed look at the Dualie Laser ATEX:

In the 3AA Laser’s packaging, along with the Dualie is a set of alkaline batteries, an Allen key and the instructions.

It the case of the 3AA Laser, the second beam is a red laser. Intended as a safe ‘pointer’ for communicating clearly what is being discussed in industrial environments.

No mistaking what added feature this light has.

Intrinsically safe and ATEX rated. You might spot one of the ATEX requirements.

I was of course referring to the locking screw.

With the locking screw tightened you can see how it engages with the scalloped edge of the bezel ring, making it impossible to unscrew the bezel without intentionally undoing the screw.

What would have been the window for the flood beam on other Dualie models is covered with a laser warning sticker.

As the laser needs to be projected forwards like the main beam, the main beam’s reflector has been modified with a hole for the laser to shine through.

Another view of the hole for the laser.

As the main purpose of the Laser model is to provide a safe pointer, the clip is a shorter version than on the Magnet model.

Just as with the previous 3AA model, there is a self contained assembly that is removed from the body which contains all the workings of the light.

A brass pill contains the laser module.

Threads are moulded into the plastic body for the removable lens bevel.

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 three lights, all with dual functions, there are several beam-shots to look at.

First up are the main beams of each and the 3AA Magnet.

Next is the main beam of the 3AA Laser oddly, though its lumen output is virtually identical it appears brighter despite an identical exposure.

The 2AA’s main beam has a much wider spill than the 3AA models, but is noticeably dimmer.

Secondary beams:
As it is the simplest to show, first we have the Laser’s pointer. That’s it. Using it with the main beam masks the spot so it is best not to do this.

With the mix of spot and flood beams, the next set of beamshots show the different beams at a distance.

Here the 2AA starts with the main beam.

Then we go to Flood.

And then both flood and spot beams together.

Changing to the 3AA Magnet starting with the main beam.

Then we go to Flood.

And then both flood and spot beams together.

Now moving outdoors:

The 3AA Magnet; its relatively weak spill fades out and the spot is left.

It is the same with the 3AA Laser.

Spot the spot…

Outdoors the 2AA struggles.

Modes and User Interface:

Operating the Dualie lights is as simple as it gets. Each of the two modes available in each light has its own switch. They can be used independently or together.

The main beam switch is a forward-click momentary type switch, and the secondary side beam switch is a reverse-click type.

Batteries and output:

The naming of each Dualie means there are no surprises that the 2AA runs on 2AA cells (alkaline or NiMh) and the 3AA runs on 3AA cells (alkaline or NiMh). The Laser is bases on the 3AA so runs on 3AA cells (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.

___________________________________________ ________________________________ ________________________________
Dualie model and mode. I.S. measured ANSI output Lumens PWM frequency or Strobe frequency (Hz)
___________________________________________ ________________________________ ________________________________
2AA – Main 103 0
2AA – Flood 75 0

3AA – Main 142 0
3AA – Flood 101 0
3AA – Main + Flood 176 0
Laser – Main 147 0
Laser – Main + Laser 146 0

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

There is no parasitic drain.

For the runtime tests, all measurements were taken with both beams on for all models. Putting all three runtime traces on the same graph, and the lower output 2AA model takes the runtime prize, but at a much lower output.

Removing the 2AA’s trace shows the two 3AA versions more clearly, and it is very obvious the Laser module draws much less power than the flood beam, as the runtime for the Laser is much longer.

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 Streamlight Dualies in use

Before looking at any other aspect, it is important to highlight that these Dualie lights are Intrinsically Safe. That really is what it says – Intrinsically Safe devices are specifically designed to limit electrical and thermal energy that might be available for ignition. It means they are effectively incapable of igniting specific explosive atmospheres. This is why generally Intrinsically Safe lights are relatively low powered, use alkaline primary cells, and are made from plastic.

Take the most typical domestic scenario; you get back home at night and smell gas in the house. You need light to find the main gas valve (which is in a cupboard) and to get to windows to air your home. Don’t touch that light switch, so what can you use in confidence? An intrinsically safe light specifically designed to be safe to operate in explosive atmospheres of course. As long as you check the certification matches the possible hazard (for example the 3AA Magnet says it is certified for methane / air mixtures only) before you really need it.

I keep a couple of Intrinsically Safe lights in the hall sideboard so I can get my hands on one straight away. I also keep a suitably rated one in the car and in the garage in case of fuel spillages.

Personally, as I don’t work in explosive atmospheres, I mostly keep Intrinsically Safe lights as standby backup lights rather than everyday use ones, but generally always have one close by. If you need this type of light for work, then you will know the regulations and exactly what your requirements are.

What is not clearly shown in the beamshots, is that there is an uneven corona around the hotspot with visible yellowing, they are definitely not the cleanest of beams. This doesn’t truly impact on their use, as it is only when you are white wall hunting and looking for beam defects that you really notice them. When you are getting on with a job, it doesn’t matter that much, and will be the least of your worries if you actually need their Intrinsically Safe aspect.

The magnets are strong enough in the two models that have tail magnets (the 2AA ATEX and 3AA Magnet), that they are able to hold the light at any angle. Taking the worst case, they will stick to a vertical steel surface and keep the light pointing horizontally. I’ve also found this to be true on steel bars as well, so not limited to flat surfaces. On the 3AA Magnet there is the additional magnet in the clip on the side of the light, providing more mounting angles. I use this side-mounted magnet for storage of the 3AA Magnet light, having it hold itself on the side of a metal cabinet ready for use.

It is important to compare like with like, and these Intrinsically Safe lights do not compete with the current Li-ion powered lights in terms of output and beam quality, but that is not a fair comparison. These are lights designed to be simple and safe to use just about anywhere. Two independent lighting functions operated by two switches, reliable and predictable AA power, light weight, tough and Intrinsically Safe. I’m certainly glad to have a few of these lights around.

Knife Review: Lionsteel T5 MI

Each year at IWA, there are a few blades that stand out and draw you back to them time and again. Lionsteel’s T5 was one of those, and may well have been my most visited blade at IWA 2017. I’ve been fortunate enough to be able to spend a lot more time with it subsequently, as well as being able to discuss its design with Mik Molletta, the man behind this outstanding knife.

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 Niolox steel.

New for 2018! BESS Certified sharpness testing:

The BESS ‘C’ scale of sharpness, developed by Mike Brubacher (Brubacher Edge Sharpness Scale) will now become part of Tactical Reviews’ knife testing process. Initially this will be used to verify the sharpness of the factory edge and allow the knife to be brought to a minimum standard sharpness before testing a blade’s cutting performance.

The Lionsteel T5’s factory edge has an average BESS ‘C’ sharpness of 233. This original edge cleanly slices 80gsm copier paper with an edge cut, but won’t quite push cut it. It slices into the rounded edge of a doubled over sheet of the same 80gsm paper. It also will catch the edge of green Rizla paper and slice halfway through (cross ways), but not all the way.

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.

Mik Molletta, kindly agreed to go through many of the design aspects of the T5 and despite a language barrier, Mik has helped with the questions I put to him. These are the marked up images that allowed us to pick out details to discuss.

The following is derived from the points we covered. Not every label has a comment:

As with many other projects, it was Lionsteel who approached Mik regarding designing a multi-role compact knife. In this case the inspiration was from talking with soldiers who need a compact multi-role knife, and this was what determined the blade length (A), as it is a good length for bushcraft and survival work.
The blade tip (B) is positioned above centre line so that as well as survival duties, it will also be suitable as a hunting knife.
To best fit with the aims of this project and its multi-use capabilities, Mik chose a ‘straight’ knife without any rake (F).
Being a multi-purpose knife, a flat grind has been chosen as this is the best solution for a blade that has to do various jobs. The blade steel, Niolox, was selected for its fine structure, good wear and toughness.
It is specifically balanced (I) for agility ease of handling and control. Texturing on the handle (K) is not merely a remnant of machining the shape of the handle, but was intentionally applied with a CNC template to give this pattern.
The T5 uses a distinctive and unusual one piece handle (L) which increases stability, precision and overall durability. In terms of the handle contours and the amount of palm swell (M), as if often the case, it’s what the designer themself finds comfortable that gets chosen.
Blade thickness (N) at 5mm is intended to still provide excellent strength for the length of blade. The extended swedge (O) reduces the blade section without weakening the tip.

Moving onto the other labelled photo of the sheath:

Though the use of a double row of stitching (P) adds to the size of the sheath, although the welt does protect the stitching from the blade, the double row increases the durability and life of the sheath so is an acceptable trade off for a little increase in size.
It is very unusual to have a MOLLE compatible (R) leather knife sheath and the use of leather was dictated by the absence of noise compared to other options. How you carry your knife is very personal so the MOLLE compatibility was added so it can be attached to a backpack or to a belt.
There is a hole behind the MOLLE strap (S) which doesn’t look right for a drainage hole as it is too high, but this is actually a construction hole simply used during assembly of the sheath.

A few more details:

The T5 arrives in a cardboard box.

Inside, the sheathed T5 is otherwise unwrapped.

Along with the T5 is a small leaflet.

However, the blade is wrapped inside the sheath.

You can see that the plastic wrapping was not terribly successful, as the blade has just sliced through it when it was inserted into the sheath.

A very nice quality leather sheath is used for the T5.

The leather is double stitched for maximum durability and lifespan.

The maker is cleanly embossed into the leather.

Here the information leaflet is slipped into the belt loop to better show its position.

Very unusually, this leather sheath has a MOLLE compatible mount.

The MOLLE strap is very snug in the loops, so not the easiest to weave onto webbing. You won’t want to move this more than necessary.

A great looking knife and sheath. This is why I kept revisiting Lionsteel’s stand at IWA 2017.

The steel specification is engraved into the blade – NIOLOX. An increasingly popular steel.

A close-up of the blade tip.

Almost the entire blade length has a swedge to help reduce weight.

The flat grind is very high, but not quite a full flat grind.

Only visible along the back of the handle, there is a full length, full thickness tang.

Sculpted from a single piece of micarta, the handle has a wide and comfortable finger guard. The cutting edge is nicely terminated with a sharpening choil.

Grip texturing is machined into the handle surface.

Two stainless Torx bolts secure the handle to the tang.

Looking through the lanyard hole, you can see the hole doesn’t go through the tang itself.

The tang protrudes from the end of the handle providing a hammering surface.

A minimal amount of jimping is included next to a thumb rest.

With a well rounded plunge line, maximum strength is retained.

Excellent attention to detail in the sheath with a protective cover over the internal part of the rivets. Doing this prevents the handle being scratched by the metal fixings.

The sheath wraps around the base of the handle providing a very secure hold on the knife. Unfortunately this makes the sheath only suitable for right handed users.

An extremely refined package.

This really is something special.

What it is like to use?

I’m going to start with that beautiful and well thought out leather sheath. Fortunately I am right handed, so this presents me with no issues, and I hope Lionsteel will offer a left handed version of the sheath.
It is the first MOLLE compatible production knife leather sheath I’ve come across, and makes an excellent change from the typical MOLLE compatible sheaths. Some MOLLE mounts are more of a struggle to use than others, and this sheath is a bit of a battle to fit. It is definitely worth planning out the position carefully as I did not enjoy fitting or removing it. The webbing on the sheath that fits over the leather MOLLE strap is quite tight, and catches firmly on the edge of the press stud when you try to slide the strap out. Easy enough when the sheath is not mounted, but definitely a struggle when trying to unmount it.
The sheath wraps over the first part of the handle with the retaining strap fitting above the finger guard. This over-wrap serves two purposes, the first is a very secure hold on the knife, and the second is that the over-wrap helps keep the retaining strap out of the way of the blade edge as it is sheathed and unsheathed.

With its 5mm blade stock, the T5 has a bit of weight to it, but that fantastic sculpted handle allows it to sit in your hand so comfortably. For a multi-purpose blade, the extra weight from the thick blade is the small trade off for the gain in strength and robustness you want in a blade that might be used for just about anything.

Handling really is excellent, and there is a thumb rest on the blade spine just in front of the handle where the spine is full width making it comfortable for the thumb to press onto for penetrative cuts, or for fine control when carving. The finger guard in that well sculpted handle is also very comfortable to bear onto for additional control on certain cuts. With the light and decorative grip texturing on the handle, I found this very effective but not aggressive. No hotspots have been apparent during use, and it is comfortable for extended use.

Factory edges are a subject unto themselves, as for some it is the best edge they ever have on that knife, and for others the worst. On the T5, the factory edge was impressive, and definitely usable out of the box. Due to the blade thickness, the edge bevels are quite wide and this will only get more pronounced with further use, but is the norm for blades of this thickness.

Mik Molletta has done Lionsteel proud with this design, and Lionsteel have done Mik Molletta proud with the quality of manufacture of his design, and this knife, that stood out from the crowd at IWA 2017, continues to impress the more I use it. The full package is a pleasure to use, and has put itself firmly into my top 5 favourite fixed blades.

Light Review: Jetbeam E01R and E10R USB Rechargeable EDC lights

Jetbeam are taking the concept of USB rechargeable EDC lights to a new level of convenience with their super compact E01R (AAA) and E10R (AA/14500), by hiding the charging port so well you would never guess they had this feature just by looking at them.

Taking a more detailed look at the E01R:

Before we go into the detail of the E01R, these are the boxes for both the E01R and E10R models.

Included with the E01R is a USB cable, spare O-ring, quality lanyard, and the instructions.

Not to gloss over that lanyard, the cord is a type of piping with a round cross-section.

This has a sliding toggle to allow you to secure it to your wrist.

Fit and finish is excellent all over this light.

The E01R has a two way clip allowing for carry either way up, and also allowing it to be fitted to a baseball cap peak to act as a headlamp.

A lanyard hole is included in the tail-cap and in the pocket clip.

The power switch is a small metal button on the side of the light’s head.

Though not an ultra compact AAA light, the E01R is still nice and small.

Inside the tail-cap is a gold plated spring terminal.

The threads are almost square, and are well lubricated.

And this is the trick up the E01R’s sleeve. Unscrew the head of the light to reveal the micro-USB charging port.

A closer look at the charging port and threads.

With the head removed, you do not see the battery, instead there is a set of contacts for the connection to the head once refitted. Just next to the spring (at about 2 o’clock) is the indicator LED for charging.

Inside the head are the matching set of contacts.

For the E01R, there is a TIR optic with an XP-G2 LED hidden at its centre.

Unlike a lot of TIR optics, you can just about see the LED.

Charging the cell in the E01R is easy, simply plug in the powered USB cable. The E01R is small, as you can see by how large the USB plug looks.

Taking a more detailed look at the E10R:

Changing over to the E10R, and exactly as with the E01R there is a USB cable, spare O-ring, quality lanyard, and the instructions.

Again the fit and finish is excellent, giving the light a refined look.

The E10R is similar in size, relative to the battery, like the E01R is compared to its battery (so not the smallest AA light). Here the E10R is shown next to its two power source options,the NiMh AA (Eneloop), and a 14500 (an AW 14500).

A small metal button is used for the power switch, which is exactly the same size as the one on the E01R.

Both the clip and the tail-cap have lanyard holes in them.

In the case of the E10R, the clip is a standard type. Even without the tail-cap loosened it is free to rotate to any position around the body.

Inside the tail-cap is a gold plated spring terminal.

The threads are almost square, and are well lubricated.

And like the E01R, unscrew the head of the E10R to reveal the micro-USB charging port.

A closer look at the micro-USB charging port and threads.

With the head removed, you do not see the battery, instead there is a set of contacts for the connection to the head once refitted. Just next to the spring (at about 2 o’clock here) is the indicator LED for charging.

Inside the head are the matching set of contacts.

Charging the cell in the E10R is easy, simply plug in the powered USB cable.

For the E10R, there is a smooth reflector with an XP-L HI LED at its centre.

The charging indicator LED is slightly hidden by a foam PCB cover. Here it is lit, showing the E10R is charging.

Indicating a 14500 is now fully charged, the charging light shows blue. (this is red if a NiMh is used)

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!

Although the beginning of the review starts with the E01R, for the beamshots, I’m starting with the E10R’s beam. The combination of the small focused SMO reflector and XP-L HI LED gives a strong hotspot and wide usable spill. A good mixture for a compact EDC light with the output power a 14500 allows.

At exactly the same exposure, the E01R looks a bit weak; this exposure is included to allow a direct comparison.

Adjusting the exposure to show the E01R’s beam more how your eyes would see it, we have a lovely wide smooth beam with a soft and gentle hotspot. A really useful close range beam.

Moving outdoors, and the E10R on 14500 has a reasonable power to give it a bit of range.

The same cannot be said about the E01R as its wide beam runs out of steam very quickly. But don’t forget this is a AAA light.

Modes and User Interface:

Both the E01R and E10R operate in exactly the same way. The only UI difference is the charging indicator.

There are three modes, High, Medium and Low, plus a Strobe mode.

To turn the E01R/E10R ON, briefly press the switch. The last used constant mode is memorised.
To cycle through the modes High, Medium, Low, High, with the E01R/E10R ON, briefly press the switch.
To turn the E01R/E10R OFF, press and hold the switch for 2s.
To access Strobe mode, with the E01R/E10R ON or OFF, rapidly double tap the switch.
To exit Strobe, either briefly press the switch (to change to a constant mode), or press and hold the switch for 2s (to turn OFF).

When charging the E01R, a red light is shown during charging. When fully charged, the red light goes out.
When charging the E10R, using AA the red and green lights come on during charging. When fully charged, the green light goes out.
When charging the E10R, a red light is shown during charging. When fully charged, the blue light is shown.

Both the E01R and E10R have an electronic lockout of the switch. To Lock, from OFF, press and hold the switch for four seconds. The LED will start to blink indicating the Lockout was successful.

To Unlock, press and hold the switch for four seconds, the last use mode will come on.

Batteries and output:

The E01R runs on NiMh AAA (or AAA Alkaline without charging feature).
The E10R runs on NiMh AA (or AA Alkaline without charging feature) or Li-ion 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.

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

There is parasitic drain in both lights. The drain in the E01R when using NiMh AAA was 41.3uA (2.21 years to drain the cell). The drain in the E10R when using NiMh AA was 69.8uA (3.11 years to drain the cell). The drain in the E01R when using 14500 was 86uA (1.19 years to drain the cell).

Where a light has built in charging, to best show how it really performs, the batteries have been charged using the built-in charger; This will show if cells are undercharged. First, note the totally flat output from the E01R, exhibiting excellent regulation on the output. Though the E10R is using an AA NiMh with 2100mAh (compared to the AAA’s 800mAh), overall the performance of the E10R using AA is much closer to the E01R than you might expect when the E10R has nearly three times the cell capacity. This is either due to the built-in charger not fully charging the cell, or the driver circuit showing some inefficiency when powered by AA. The 14500 is where the E10R comes to life with nearly 500lm output, staying above 300lm for 25 minutes and only stepping down to below 200lm after 30 minutes.

Troubleshooting

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

The first E01R supplied would not charge. This seemed to be due to a connection issue with the micro-USB port. Jetbeam promptly replaced this under warranty and the replacement has functioned perfectly.

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 E01R/E10R in use

Many USB rechargeable EDC lights have built-in batteries. Though very convenient, this means there is no option of replacing the battery with a fresh cell if you need more light than one cell will give you. Both the E01R and E10R run from standard cells, so whether you use the built-in charging, or not, you can still swap out empty cells for fresh as needed. Both will also run on an alkaline cell, so you are covered in all ways.

Unlike those convenient EDC lights with built-in cells, the E01R and E10R give you that extra level of confidence. Crucially of course you get the performance of a ‘proper’ light.

By hiding the USB charging port inside the head, the port is protected by the O-ring seal of the head. A simple design feature which makes the light just as waterproof as any other non-rechargeable light. This has got to be one of the most important aspects of the way Jetbeam have designed the charging of theses lights; in the majority of cases a USB charging port does compromise the waterproofing – not here.

My main criticism of these lights is with the UI. Firstly the button is quite small and sometimes not easy to hit first time. Secondly the fact that you need to press and hold the switch for 2s to turn it off is quite annoying. Personally I’d much rather the output went on and off with a brief press, and the mode change was a 2s press, but unfortunately it is not.

Another minor annoyance, but probably unavoidable, is that the clips press onto the side of the head, meaning they rub against the anodising as you unscrew the head for recharging. I lift the clip slightly before unscrewing the head to avoid wearing the anodising prematurely – many wouldn’t bother.

Finding the switch can prove challenging by feel, so it can be a little frustrating when you miss the button. I have made this a bit more reliable by lining up the clip so it is opposite the button, but the clip is not held tightly and can still rotate, so this method can end up failing. Also, in gloves, you have no hope at all of finding where the button is, so end up working your way round the head until you hit the right spot. The flip side to this is that the lines of these lights are very streamlined and clean looking.

Moving past these niggles, and onto the beams, the E01R has an outstanding EDC beam. Wide, smooth and perfect for short distance and indoor use. It is also surprisingly bright even with only 111lm. The levels are very well chosen, with Medium being the most useful for general purposes. Neither model includes a genuinely low, low, moon mode, but the low level at 2-3lm is probably more useful for those situations where you want a low level but your eyes are not fully dark adapted; even if they are, the 2lm level is not shockingly bright (it is amazing how little light your eyes really need if given the chance).

More and more lights are including USB recharging, simply because it is much more convenient to charge the battery without taking it out, (and you don’t need to buy a dedicated charger). Jetbeam have achieved this with the E01R and E10R without compromising the style, integrity or function of the lights, and in the E10R have a charger that can charge NiMh and Li-ion!

Light Review: Streamlight Vantage 180

Streamlight make some of the most useful articulated-head lights I’ve ever used. Lights like the Knucklehead, and Sidewinder bring an extra level of functionality with their adjustable heads. For this reason I was particularly excited to get my hands on their latest articulated light, Streamlight’s Vantage 180.

Taking a more detailed look:

The Vantage arrives in a cardboard box.

Inside is the Vantage 180, a pair of Streamlight branded CR123s, the helmet mount with Allen key, plus the instructions.

And here we have the, very orange, Vantage 180. On this side it has ‘Streamlight’ written.

On the other side it has ‘Vantage 180’.

Laying the Vantage 180 on its side shows where the switch is positioned. As you would expect, it is on the opposite side to the clip.

And now we get to the reason for the ‘180’ in the name. Here the head has been rotated 90 degrees to the front.

Then from the previous position, the head rotates a full 180 degrees all the way to the back. There are no click stops, instead it is held in place by friction, so the head can be adjusted to any angle between these two extremes.

With the head either fully forward or backwards you can access the built-in turn out gear hook / hanging loop.

While we are looking at attachment options, there is a special helmet mount included with the Vantage 180. It is an anodised aluminium block with a few special features.

There is a deep helmet rim clamp. Using the supplied Allen keys, these two grub screws are backed right out to allow the mount to be placed over the rim of the helmet. This is specifically designed to fit US issue helmets, so might have limited success on other helmet designs around the world.

Then there is the side onto which the Vantage 180 clips. The round section fits against the Vantage 180’s body, and the T-shaped groove will allow the pocket clip to slide through.

Something extra to mention while looking at the full pocket clip, is a feature that is visible bottom left in this photo; where the clip joins the body there is a slot. The pocket clip can be moved from side to side here, rotating the position of the clip around the body slightly and allowing the user to angle the Vantage 180 up to 15 degrees to either side while it is clipped to their gear.

The feature of this clip that relates specifically to the helmet mount are the two notches each side of the clip. These are what the helmet mount latches on to so it doesn’t slide out of the mount,

Starting to slide the Vantage 180 into the mount. From this side you can see the mount’s release lever.

The mount is now locked in place on the clip.

An overall view of the Vantage 180 fitted to the mount.

A brief reminder of the modes, and how to use them, is printed on the body (more on this later) along with the battery orientation.

There is another special feature of the Vantage 180; it has two beams. This is the second beam, and is itself dual-purpose, either as a blue marker light, or a white secondary beam down-light (more on this later).

Here is a little mystery, I’ve not yet uncovered why there is an interference pattern visible (like oil on water) on the lens. It appears to be an additional layer on the lens front, but not one you are meant to remove, as there is no visible edge that would allow you to remove it. This doesn’t seem to affect the output in any way, so this is just an observation and appears to be normal.

A TIR optic is used.

And this means that when viewed from the front, you can’t see the LED.

The tail-cap has a deep grip pattern making it easy to hold onto.

The simplest of contact design is used, with a single coil spring fitted into the plastic tail-cap.

Though moulded plastic, the threads are sharp and well made. The O-ring is a wedge type.

Being a plastic body, the negative contact needs to connect to the head of the light. This is via a ring contact at the end of the battery tube which is soldered to a metal strip that runs through the battery tube.

Looking into the battery tube you can see the positive contact.

With the head adjusted to 90 degrees, the secondary beam provides downward lighting.

That same secondary beam, also changes to a blue marker light.

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!

In this photo, the tail beam has been turned on and (with the head set to the straight position) is a relatively low output blue light.
The main beam is almost entirely hot-spot. The spill is useful, but is quite weak, so this can give a slight tunnel vision effect depending on the environment.

With more range the effect of the weak spill becomes more pronounced, and really the beam becomes just the hotspot.

Modes and User Interface:

The Vantage 180 has two constant output modes for the main beam, High and Low, and two different outputs for the secondary beam, white and blue.

To access High, press the switch once. If you press the switch again within 2s, the Low mode will be selected. Pressing once more within 2s turns the Vantage 180 OFF.

If either High or Low mode is activated, once it has been ON for at least 2s, a single press of the button will turn the Vantage 180 OFF.

The secondary beam is set to be either ON or OFF along with the main beam. The secondary beam cannot be used independently and can only be on if the main beam is on. Its white/blue setting is dictated by the head position.

To set toggle the secondary beam between being ON or OFF, with the Vantage 180 either ON or OFF (it doesn’t matter), press and hold the switch for more than 2s.

With the head set to the straight position, the secondary beam will be blue.

Angling the head towards being a right-angle light, and when the head gets to around 72 degrees, the secondary beam switches from blue to a brighter white.

Batteries and output:

The Vantage 180 runs on 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.

___________________________________________ ________________________________ ________________________________
Vantage 180 using specified cell I.S. measured ANSI output Lumens PWM frequency or Strobe frequency (Hz)
___________________________________________ ________________________________ ________________________________
High – CR123 269 0
Low – CR123 98 0

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

There is parasitic drain; when using CR123, the drain was 23.2uA (6.88 years to drain the cells). The tail-cap can be unscrewed two full turns to lock-out the power and stop any drain. However this is enough to prevent the seal being effective, so the Vantage 180 would not be water resistant like this.

The runtime graph shows a nicely regulated output giving nearly two hours on High before the output drops to the Low level. Beyond two and a half hours the output then rapidly declines before dropping to a 22 lumen level which runs on for some time. The Vantage 180 doesn’t leave you in the dark and provides plenty of warning for a battery change.

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 Vantage 180 in use

Streamlight always manage to build in a great deal of functionality into lights like this, and the Vantage 180 does not disappoint. To start with, the ability to go from a conventional straight torch/flashlight to a right-angle light, or anywhere in between, is so useful. Even if this is when placing the Vantage 180 on a table or the ground to use as a task light, being able to adjust the head, allows it to work where a fixed head light just wouldn’t be much use.

Add to this the clip (with its own adjustment of 15 degrees each way) and hanging loop, and you have a highly functional work light, that will fit into just about any task you need to do.

Then there is the secondary beam. The blue tail-light is mainly for increasing your visibility to others, and this is mainly aimed at Emergency Response personnel who would wear the Vantage 180 on their helmet. For my own purposes, I can’t really think of a sensible use for this blue marker light.

However, rotate that head to activate the down-light, and the Vantage now has ground lighting along with the main beam if you have this fitted to your clothing (or lighting to let you see what you are writing etc.).

But we are not yet finished as there is that solid helmet mount. So as long as it fits the helmet you are using, or can be made to fit) you have a headlamp as well.

In this case it has been fitted to a basic hard-hat and nicely holds onto the rim.

Not everyone will use every feature of the Vantage 180, but you know that it has all that flexibility built-in which provides you with a lot of options.

Knife Review: Cold Steel Espada XL G-10

Inspired by the classical Navaja knives of Spain, Cold Steel’s Espada series are the result of a design collaboration between custom knife maker Andrew Demko and Cold Steel President Lynn C. Thompson, using modern design and materials to bring extreme performance to a range of huge folding knives. In this review we are looking at the largest of all, the Espada XL in the newest G-10 edition.

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 Carpenter CTS XHP Alloy with DLC Coating.

A few more details:

For such a large knife, the Espada XL G-10 arrives in a relatively compact box.

However, this is because the knife completely fills that box.

In most cases I think it is over the top to put a warning on a knife that is it sharp, but the Espada XL is worthy of extra caution with that huge sweeping belly of the blade eagerly waiting to bite like a ravening dog.

And there we have it, the Espada XL fresh out of the box.

That massive blade has a thin film of oil on it.

It is the oil giving the blade a slightly mottled appearance. As supplied, the clip is fitted for a right-handed person.

The G-10 version is made in Taiwan.

The sweeping clip echoes the lines of the curved handle.

On one side, the pivot bolt is completely plain. You get a hint of the texture on that peeled G-10

Looking in closely at one of the handle bolts the super grippy texture of the peeled G-10 is clear. This surface is created by peeling off one of the layers of G-10 material leaving the pattern of the weave in the surface of the resin. It makes for a super grippy surface.

Blade centring is excellent, especially considering the huge length of this knife.

For the highly stressed areas of the lock and pivot, there are steel liner inserts. At the pivot end these are textured on the edges for grip.

Those steel liners extend beyond the end of the lock bar to spread the forces further into the handle.

An overall view of those steel liners.

Three torx screws hold the clip in place, and the clip fits into a recessed pocket cut into the handle surface.

Ready for left-handed configuration the other side of the handle has the pocket for the clip to fit into. The clip is not moved from one side to the other, only the screws are reused to fit the left-handed pocket clip included in the box.

Getting ready to bite!

Especially considering the length of the blade, the Espada XL’s factory edge is extremely keen. You can see this is a toothy edge, but it has been finished well.

The ‘eager’ edge is topped off with a very acute angled point.

I’m pleased to see a sharpening choil at the base of the plunge line, and that the corners of the plunge line are radiused to reduce stresses.

Complex curves create several grip options along the very long handle.

Of course the Espada XL needs to have a Demko Thumb Plate to make it even more awesome with out-of-pocket-opening.

All the edges of the grip are well rounded so as not to cut into your hand. The first finger grip groove is generously sized with deep finger guard.

Moving to the middle of the handle and a spur provides masses of grip for the front or mid-grip hand positions.

Grip options extend right through to the hooked end of the handle.

On the Espada XL the trailing point blade has a huge elegant sweeping curve to the tip.

What it is like to use?

Cold Steel describe the Espada series as ‘pocket swords’ and with the Espada XL this is an apt description, but I’d like to move away from the connotations that has and onto the enthusiasts point of view.

Honestly I can’t say the Espada XL is a practical tool, but who cares; it is an awesome giant folding knife!

Actually it is very capable as a slasher for jobs where you would use a machete, so if you want a very expensive folding brush clearing tool that will keep you grinning, look no further. If you happen to have large blocks of material that need deep cuts, it also excels at this (like thick foam rubber for cushions), so you can argue a level of practicality, even if a bit of a reach. But practicality is not what this knife is about; it is an enthusiasts knife.

When you are using it, there are many different grip options. Starting with the primary forward grip for working with the blade for cuts requiring the most strength to be applied.

Moving to the mid-grip and with the spur between your middle fingers you have more reach and like this can use the blade to cut precisely or to chop.

Taking up the most extreme hand position on the final hook of the handle and you have very long reach and like this would primarily slash and chop instead of making more controlled cuts.

Let’s jump into a short video with some slow motion opening and cutting.

Video Edited with – Cyberlink Director Suite 5 (PowerDirector 16 and AudioDirector 7)
Camera – Panasonic HC-V770    Microphone – Tonor TN120308BL

This wood chop was not shown in the video, but I wanted to include it to show a cut made into a well seasoned fencing board, that was placed, unsupported, on the ground. The cut was made at a 45 degree angle towards the ground, so the bottom of the board could not move downwards, but nothing held it sideways except the inertia of the board itself. A very deep cut was the result; not all the way through, but impressively deep.

Using the factory edge (with no touch up at all), this lightweight cardboard tube has a very clean-edged slice through it.

The video also showed some size comparisons, but here they are as photos.
In this image we have the Espada XL along with another well known large folder, the Cold Steel Rajah I (the same size as a Rajah II) and a standard size Victorinox pocket knife.

So, the Espada XL is not the largest folding knife I have, the Opinel No. 13 ‘Le Géant’ is, which in terms of pure size does beat the Espada XL, but it is nowhere near as robust.

And just because I wanted to, this is a Master Cutlery First Blood replica, showing what a beast the Espada XL really is.

Along the way with this review, I had reason to open the Espada XL up. This proved to be a very easy job, and allows me to show a few internal details. Once you have the pivot bolt and three handle bolts undone, the handle lifts off easily and initially leaves its steel liner in place. This then lifts off easily too.
With the blade then opened up, you press the lock bar to relieve the pressure on the blade tang and lift the blade off the pivot. The lock bar, once you release the pressure, then lifts off its pivot.
Note that the washers look different here, but that is because each washer is made of two thinner washers, a nylon or teflon (white) washer positioned next to the blade, and a phosphor-bronze washer between the nylon washer and the G-10 handle.

A closer look at the pivot bolt and the nylon washer.

Zooming in on the two-part washer.

Keeping the super strong Tri-Ad lock locked, is a heavy spring, one of the strongest I’ve come across in a back lock.

The Espada XL is a GIANT folding knife, and definitely needs consideration if you want to carry it. You’ll need a deep pocket (like leg pockets on cargo trousers) and the will to have a mostly impractical blade on you. However the genius of the Espada XL’s design is that you CAN carry such a big knife and not be too weighed down by it.

Another point to note is that though the G-10 edition may well be the cheaper version of the Espada XL, actually I’ve found it to be more usable (if not as beautiful). Mainly this is due to the super grippy handle and the fact there is no polished aluminium to get scuffed up through use. According to Cold Steel, the G-10 edition retains 90% of the strength of the original, and it is slightly lighter (50g or 1.8oz). I really must come back to that grippy handle; no matter how sweaty or wet my hands are there is no lack of grip, unlike the polished handle of the original. This is to such a degree I have considered sanding the handles a bit to take off some of the ‘sharpness’ in the surface texture, as it can be pretty abrasive. This is definitely something you might want to do under the clip as you will wear away your pocket very fast if you don’t.

This knife is just so much KNIFE, you want to find a reason to carry and use it.

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.

This is a really BIG knife! This is a really BIG knife! (It is not a mistake putting this in both columns.)
Super strong Tri-Ad lock. Demko opener ‘eats’ your pocket.
Very grippy handle. Handle can be overly abrasive.
Pocket carry is possible despite the size.
Demko Opener allows rapid blade opening..
Extremely ‘eager’ blade wants to cut everything.
This is a really BIG knife! Enthusiasts will LOVE it.

Light Review: Surefire 2211 Signature Wrist Light

Surefire have expanded the choice in their 2211 Wrist Light range with the addition of the 2211 Signature Wrist Light. This features an integrated watch face (like the Luminox version) which is a special new Surefire branded version.

Taking a more detailed look:

This review sample was a final pre-production example, so had no packaging and has a rubber strap instead of a NATO strap. All other details are the same as a production version.

You might have seen the earlier ‘Luminox’ version of the 2211 Wrist Light, so this large watch may look familiar, but is the new ‘Signature’ model.

At the 3 o’clock position there is an angled, faceted reflector creating Surefire’s “MaxVision Beam”.

And at the 9 o’clock position there is the watch crown and USB charging port.

A bold tactical style watch face is incorporated into the 2211 Signature. Note there is some reflection in the glass of the camera lens so this is not any type of smudging on the watch face.

Being a rechargeable model, the 2211 Signature has a micro-USB B port for maximum compatibility.

For a watch, the body is exceptionally thick, but that is of course because this is a Wrist Light. Remember the strap on the production model is a NATO strap.

The back of the 2211 Signature is a smooth flat plate.

On opposite sides of the 2211 Signature’s body is a rubber covered switch.

A closer look at one of the two switches.

There is a 60-click unidirectional bezel. The watch glass is not specified, so is most likely mineral glass.

On the face there are bold numbers and this is surrounded by clear markings on the dial ring. The hands stand out well with large areas of lume providing the contrast.

An XP-G2 LED sits in the bottom of the angled, faceted reflector of Surefire’s “MaxVision Beam” first seen on the Titan.

Charging is simple, and you just need a Micro-USB charger.

During charging the ‘fuel gauge’ window lights up red. This starts to turn a slightly amber colour and once fully charged it turns green.

The hands have lume on them, but there is no lume on the rest of the watch face.

Strap fitting / changing is easy as the lugs are positioned so that you can release the spring pins using a pusher.

To access the watch, first loosen the two black Allen bolts near the lens of the light.

Then loosen the two Torx grub screws either side of the crown.

You can now lift out the watch.

The recess in the 2211 Signature’s body for the watch to fit in, plus the four fixing points, two bolt holes and two grub screws.

The watch itself is a completely self contained module.

On the back of the case we see the only indication of waterproofing with a 100m water resistant rating (which is not shown on the watch face).

Here you can see one of the four watch back screws. In the centre of the image the slight ding in the plastic case created by the grub screw is visible. The groove in the crown is essential for ease of use, as will be explained in more detail later.

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!

Surefire’s “MaxVision Beam” is a lovely smooth part-focused, part-diffused beam that gives you a soft edged hotspot and reasonably wide spill. Here you can see the tendency of a Wrist Light to catch the user’s knuckles in the outer edge of the spill (on the right hand side). We’ll see what this beam looks like with a sight picture later on.

Modes and User Interface:

In this section I’ll be referring to the operation of the Wrist Light rather than the watch. The watch movement is a Citizen 2115 and operates exactly as you would expect a simple date display movement to work.

There are two electronic switches on the body, positioned on the sides at the 12 and 6 o’clock positions. These control the three constant output levels.

To turn the 2211 Signature onto High – pressing either switch once. To turn OFF press either switch after it has been ON for at least 0.5 seconds.

To turn the 2211 Signature ON to Low – pressing either switch twice within 0.5 seconds. This will turn onto High and then to Low. To turn the light OFF, press either switch again once.

To access Low directly on the 2211 Signature – press and hold both switches simultaneously. This will turn ON to Low. If you continue to hold both switches, the output will cycle through Medium, and then High 0.75 seconds apart. Release both switches when the desired output has been reached. To turn the light OFF, press either switch once.

NOTE: Surefire state “Do not activate, deactivate, or adjust your 2211 Signature while holding a firearm.” – heed this warning.

The 2211 Signature has a ‘Fuel Gauge’ LED to indicate the battery charge status during use and while charging. GREEN means the battery is full (or has reached at least 90% when charging). AMBER indicates the battery is low and the output level should be reduced or the 2211 recharged. RED indicates an empty battery and the 2211 should be recharged immediately.

Batteries and output:

The 2211 Signature runs on a built-in battery. For the watch, the Citizen 2115 movement is powered by a SR626SW / 377 / AG4 button cell which is expected to last 2-3 years.

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.

There will be parasitic drain but it cannot be measured due to the design. Long term testing of the Surefire Sidekick would indicate that this drain will be very low.

This particular 2211 Signature sample both over and under performs. Maximum output is more than the specified 300lm output for the first 30 minutes of use, but runtime is lower than the one hour specified. Between 20 and 27 minutes, the output fluctuates by around 55lm where the battery is starting to struggle to maintain the over 340 lm output. This then settles into a gradually stepping down output through the 30 minute mark, dropping more rapidly and reaching the ANSI cut off at 45 minutes of total 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 2211 Signature in use

Although pictured with the rubber strap provided with this sample, in line with the Surefire final specification, I’ve changed this and used it with a NATO / ZULU strap. I have also tried it with a metal bracelet strap just to see how this worked.

It is a really good call by Surefire to go with the NATO strap for the final version as this means that the failure of a single strap pin will not cause the 2211 to fall off (which is the reason for the NATO strap design itself).

For those not familiar with this type of strap, here you can see how the nylon webbing passes behind both strap pins, so if one breaks, it will still be attached to the strap.

In use, I’ve also found (thanks to trying all strap types) how critical it is to have the most stable fitting on your wrist. You need to fit the strap to be snug, as any looseness results in the beam being less controllable and responsive.

You certainly know when you are wearing the 2211 Signature as it has real presence on the wrist. There is definitely a sleeve incompatibility consideration as the depth of the 2211 Signature means it doesn’t easily fit into most sleeves. Taking off a jacket or shirt is not really an option with the 2211 Signature on your wrist. It is better fitted to the outside of a sleeve or glove cuff, but you’ll need to try out a few things to find what works best for you. The ideal arrangement is summer clothing with no sleeves at all.

So, does it work? Based on the 2211 Signature being fitted securely to your support hand wrist, and being turned on before handling a firearm, without even thinking about it, you come up on aim and there is light on the target. You can see that the right hand edge of the spill is showing knuckle shadow, but there is still plenty of light to work within.

Searching, moving and tracking brings the light with your sight picture, and points as naturally as the sights (as long as it is fitted securely and is not loose on the wrist). But you don’t have access to turning it on or off.

A crucial point to note here is that this system does not work if worn on your primary hand, the one holding the gun. Due to the wrist position being too close to the centre line of the gun, the gun hand blocks half of the beam leaving you with only half the target area lit. In my testing this was more or less a vertical line at the point of impact.

Taking this to the next conclusion, the 2211 Signature is only suitable for right handed people (or at least those who hold their gun in their right hand). It must be worn on the support hand, so for left handed people, this means that with the light pointing forwards the watch face will be upside-down if worn on the right wrist. Left handed people may as well go for the non-watch versions of the 2211 range.

Another point to note with the 2211 Signature is due to the crown being positioned at 9 o’clock, you can’t adjust it while wearing it (unless you are a contortionist). The groove in the crown is essential to allow the, effectively recessed, crown to be pulled out using your finger nails; not the easiest crown to use.

Of course, one major advantage is that you are not going to drop this light, so gives you the benefits of hands-free use. Unlike any other hands-free options (excluding gun lights), the location of the light makes it ideal as it naturally points with the gun and doesn’t shine onto the back of the gun (which would create glare).

Like all tactical equipment, one is none (two is one), so I would not see the 2211 Signature as the only lighting option one would carry, but it does give you a really functional option for those instances where it fits in with your clothing. The major advantage of the 2211 Signature over the plain wrist lights Surefire make is that you won’t need to sacrifice wearing a watch, as the 2211 Signature includes a timepiece.
