Knife Review: ANV M311 COMPACT

The M311 COMPACT is a scaled down version of the excellent M311 Spelter. The reduction is 13%, bringing the overall length down to 235mm and blade to 110mm, while completely retaining the M311’s distinctive characteristics.

With the M311 Spelter being one of my favourite knives, the announcement of the M311 COMPACT had me sitting on the edge of my seat waiting to get hold of one and try it out.

Join me in this detailed review of the ANV – ACTA NON VERBA Knives M311 COMPACT to see what it is really like.

Before we properly embark upon the full review of the M311 COMPACT, lets see what that 13% scaling down looks like compared directly to the original M311 Spelter.

Including the sheaths initially as this is the package you carry.

Then the knives themselves next to each other. 13% doesn’t sound much, but it makes a big difference. The original M311 Spelter is a substantial knife. With a 13% reduction, the M311 COMPACT becomes much more EDC than expedition.

A few more details:

What’s in the box?:
The ANV packaging has had a slight update where the knife is held in a liner which stretches a clear plastic film over the knife to keep it firmly in place.


A good look round the M311 COMPACT’s Sheath – Things to look out for here are:
With the scaling down, all the parts ANV make are reduced, but the MOLLE straps are not, so become relatively more prominent features. Looking beyond these, we have a Kydex sheath with hollow rivets holding it together. A generous free running drainage hole at the tip of the sheath ensures easy flushing if needed, and the number of hollow rivets and slots give you lots of attachment points.


A good look round the M311 COMPACT – Things to look out for here are:
ANV’s distinctive swedged blade never disappoints on the looks front, giving it immediate appeal. It may be scaled down, but all the proportions and details are still spot on.
3D milled scales, finger guard and first-finger groove, all provide excellent grip, and then there are also three sections of jimping in the full tang. The M311 has a shaped thumb rest on the blade spine to allow for powerful cut control and pressure to be applied directly behind the edge.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.

The blade is made from Elmax steel.


The Factory edge up close:

Followers of Tactical Reviews will know my views on factory edges, but to recap:

Anyone using a knife will need to sharpen it. That first factory edge is just like the first tank of fuel that a new car comes with (or first charge of the battery).
A good factory edge is a ‘nice to have’ but not a ‘make or break’ for a good knife, as you will be putting your own edge onto it soon enough.
The factory edge does however indicate the care a knife maker has put into the final finish.
It is for this reason Tactical Reviews measures factory edge sharpness and specifications, and includes this information in the detailed technical testing.

As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.


What is it like to use?

Local laws may or may not allow a fixed blade to be carried as an EDC. Unfortunately where I live you need ‘good reason’ to carry a fixed blade in a public place, however on private property and when I do have good reason, my preference is for a compact fixed blade. The M311 COMPACT has muscled its way into my top carry spot, the closest a fixed blade can be to being my EDC.

Take a look at it in the hand. (I take XL size gloves.) It is not small, but it is also not a large knife, instead finding a really efficient and effective sizing that gives you great cutting power without great size.
Multiple grip placements allow you to find the one that gives you the best advantage for any task.


Though the M311 COMPACT is a scaled down M311 Spelter, one observation I have is that oddly it feels ‘crisper’ in terms of its handle finish, and this makes it a little more abrasive to hold and use. Excellent grip, but oddly a touch more fatiguing to use purely from the roughness of the handle. This is a ‘feel’ more than anything really tangible, and for the tasks I tend to use it for, not a problem at all.

Wanting to be carried, the M311 COMPACT has made itself a go-to blade, patching up some air conditioning ducting, trimming down a mouth guard, and splitting up pallet wood are only some of the varied jobs it demanded to be used for.

As I mentioned earlier, with the smaller scale M311, the MOLLE straps became larger, and I decided to drop these in favour of (at the moment) a single Ulti-Clip. The bare sheath allows the M311 COMPACT to slip easily into a pocket or bag, and adding an Ulti-Clip for pocket carry then makes it so easy to pick up the knife and re-sheathe over and over.


If you look at the position of the Ulti-Clip, this was settled on after trying several positions. Deeper carry makes the re-sheathing more difficult, with the finger guard often catching on the pocket edge. If the clip is fitted to the other side, the sheath twists away as you re-sheathe it, so this was the position that worked best for me. If you needed more stability, a second Ulti-Clip would lock it in place; this is just a personal preference.

Local law allowing I would carry this knife much more, I do however carry it as much as a possibly can. EDC or backup blade the M311 COMPACT demands to be picked up and used.

Knife Review: Sandrin Knives Torino

A Tungsten Carbide bladed knife! The Torino from Sandrin Knives features a blade made from Polyhedral Tungsten Carbide (PTC), a flexible grade of tungsten carbide that has superb edge retention and measures HRC 71 on the Rockwell scale.
The Torino’s blade also has a unique ‘raw carbide’ finish, giving it its striking appearance. Pivoting on ceramic ball bearings provides a super smooth opening and closing action, with the blade held securely open by a Recoil Lock mechanism.
Join me in this review of the Sandrin knives Torino for a thorough look at the knife.

Review Video

A thorough look at the Sandrin Knives Torino with the Tactical Reviews detailed technical specifications and close up view over the entire knife.


A few more details:

A good look round the Torino – Things to look out for here are:
Using red, high visibility, milled G10 for the handles and a reverse-skeletonised design to reduce weight gives a very distinctive look to the Torino (even before you see the blade).
A black PVD coated pocket clip can be fitted on either side or removed completely.
The Polyhedral Tungsten Carbide blade’s raw TC finish adds further to the distinctiveness of this knife combined with the fact the Torino’s blade is super slim at a maximum of only 1.2mm thick!
Sandrin Knives have used a Recoil Lock for the Torino with a sliding back spacer lock lever on the back of the handle.
PTC, being super-hard at HRC 71, gives the Torino’s blade a very different look on the primary and edge bevel grinds.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.

The blade is made from Polyhedral Tungsten Carbide.


Explained by the Maker:

With the unique material used for this knife blade, I’m including the manufacturer’s own description here for ease of reference.

An advancement in the science of blade materials, Sandrin knives are crafted from our patented Polyhedral Tungsten Carbide (PTC), a flexible grade of tungsten carbide that outperforms steel in edge retention. Measuring HRC 71 on the Rockwell scale of hardness, Torino retains its razor-sharp edge far beyond steel knives. We call this StaySharp Technology™. New for Torino is the blade’s raw carbide finish – its striking appearance is achieved by grinding the PTC with fine diamonds. Unlike steel, the Torino blade is completely rustproof making it suitable for both fresh and saltwater conditions. The blade’s thumb ramp features carefully executed jimping, while the rest of the spine and finger choil is chamfered for comfort.

Torino’s ceramic ball bearing action provides for a smooth opening and closing experience. A robust thumb stud provides for one handed blade deployment. But what really makes the Torino a modern marvel is a completely redesigned mechanism we call the Recoil Lock. This ingenious locking system is a gift to the knife community by knife wunderkind Snecx Tan, who refers to it as his PowerLock. Thank you, Snecx, for this remarkable innovation. The beauty of Tan’s recoil lock is the simple yet efficient design. The ambidextrous action delivers positive force (grip) to secure the blade in its rock-solid open position. Closing the knife is accomplished by sliding the backspacer to the rear, eliminating accidental blade unlock.

High-visibility red G-10 handles provide for quick acquisition in emergency situations. Stylized pockets serve to both reduce weight and add tactile feel for positive grip engagement. A reversible titanium pocket clip enables right- or left-hand carry and features our Fibonacci hole sequence design, a distinctive mathematical trademark of Sandrin Knives.

At only 2.29 ounces, Torino is so lightweight it practically disappears in your pocket. And, with a blade length of 2.95 inches, it’s also legal to carry in most jurisdictions.

The Factory edge up close:

Followers of Tactical Reviews will know my views on factory edges, but to recap:

Anyone using a knife will need to sharpen it. That first factory edge is just like the first tank of fuel that a new car comes with (or first charge of the battery).
A good factory edge is a ‘nice to have’ but not a ‘make or break’ for a good knife, as you will be putting your own edge onto it soon enough.

It is for this reason Tactical Reviews measures factory edge sharpness and specifications, and includes this information in the detailed technical testing.

As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.

The magnified images of the edge show the Torino’s blade’s different look. They also show what appears to be a micro-serration from the grinding process, which aids the cutting ability of this special material.


What is it like to use?
One of the most noticeable features of the Sandrin Knives Torino when you use it is the super-slim, super-slicey blade. The sharpness measurements for the factory edge, are in this case more important than most knives, as I suspect the PTC blade may be difficult to sharpen, and will almost certainly want diamond sharpeners.
Sandrin have supplied the Torino super sharp with the very impressive average BESS measurement of 165. I tend to sharpen a knife to less than 200 BESS, so this is sharper than my normal target sharpness.
Actually with it being so so hard, I’ve not yet worn the edge enough to want to sharpen it, so this aspect of using the PTC blade is to come later.
It certainly is lightweight and easy to carry.
The jimping on the spine of the blade is useful, but with the blade being only 1.2mm thick, I find it quickly becomes uncomfortable to apply a lot of force directly onto the blade spine.
With the forward placed finger groove, choking up on the blade is natural and makes finer work really accurate.
For me, the only aspect that lets the Torino down somewhat is the spring pressure on the recoil lock combined with the finish on the lock lever – together these make unlocking with the pad of your thumb uncomfortable and not entirely reliable. I find I tend to have to curl my finger or thumb over and use my nail to get sufficient purchase to release the lock. If the lock bar protruded a little more and the spring pressure was slightly less, I think this would come together nicely.
However, that said, the recoil lock does allow the Torino to remain slim and gives a reliable lock-up.

Knife Review: Benchmade Bugout 535-3

An even lighter, premium version of the already ultralight Benchmade Bugout, yes, that’s right. Join me in this is detailed review of the Benchmade 535-3, the special super-ultralight Bugout. Now, you say Carbon Fiber, I say Carbon Fibre, but let’s not worry about that (I might use either or both), and this is why the 535-3 is even lighter, as it has Carbon Fibre handles with the minimal steel inserts milled into them. The 535-3 is the Benchmade Bugout – Plus!

Review Videos

Starting with a short format sixty second review:


Onto a full video review covering many more details:


A few more details:

What’s in the box?:
Very well presented in a foam lined box, the Bugout comes in a cloth bag that you can use to help keep the pocket fluff at bay. A clip/handle protector card also gives you information about the Benchmade Axis lock that the Bugout uses.


A good look round the Bugout 535-3 – Things to look out for here are:
The Bugout uses a mini deep-carry steel pocket clip, that is removable and can be fitted on either side. Blue highlights on the spacer/lanyard hole and thumb stud, play beautifully off the black Carbon Fibre adding to the premium feel of this version of the Bugout.
Ultralight construction means there is only the one spacer and otherwise clear space through the handles.
One side of the pivot bolt is capped, and the torx screw head on the other side only. Torx screws are used throughout for the construction.
Looking in closely at the axis lock bar and how it moves as the blade is opened. The Bugout, despite being a lightweight knife, is also known for being tough, and the use of phosphor bronze washers adds to the robust and reliable build.
There is something about this particular blue and how it sings on the ambidextrous thumb studs.
And then we have the Bugout’s slim, flat ground blade. No weak points, and very ‘slicey’ (should be a word if it isn’t) with a very useful shape. The smooth plunge line ensures maximum strength and exposed heel-edge provides easy maintenance and a useful rear-point (there isn’t a sharpening choil, but the end of the edge closest to the handle is unobstructed and easy to sharpen). This detail is something I look for in all knives, but especially an EDC knife.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.

The blade is made from S90V steel.


The Factory edge up close:

Followers of Tactical Reviews will know my views on factory edges, but to recap:

Anyone using a knife will need to sharpen it. That first factory edge is just like the first tank of fuel that a new car comes with (or first charge of the battery).
A good factory edge is a ‘nice to have’ but not a ‘make or break’ for a good knife, as you will be putting your own edge onto it soon enough.
The factory edge does however indicate the care a knife maker has put into the final finish.
It is for this reason Tactical Reviews measures factory edge sharpness and specifications, and includes this information in the detailed technical testing.

As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.

Please be aware that these images were taken with the knife straight out of the box without any stropping and they do have some manufacturing residue visible on the edge.


What is it like to use?

The Bugout is a modern classic and has gained much favour and recognition. This is actually the first Bugout I’ve owned (not the first I’ve handled), so prior to this period of review testing I did not have much experience of using a Bugout. I’ve not been disappointed at all, quite the opposite.
With the 535-3 being the lightest Bugout to date, an already ultralight knife, it sits like a feather in your hand. The Carbon Fibre feels so light, comfortable and warm to the touch, you don’t want to put it down. How can it be so strong and so light?
Benchmade have also got the blade geometry spot on. Using a thinner blade, but not too thin, makes it slice exceptionally well. The exposed heel of the edge (similar to when a sharpening choil is used) makes sharpening of the entire edge easier. I find this secondary ‘point’ a very useful feature for fine work.
Shown here in my XL-glove-size hands, there is enough handle for a firm grip, while the overall knife is compact enough (and very slim) to forget you are even carrying it.


It’s proven its worth with all sorts of random jobs. Here a chandelier replacement candle tube being trimmed to length, and then its been out with me dealing with anything and everything else life has presented.
This edition with the Carbon Fibre handles has been making it so difficult to put down. It want’s you to carry it, it wants you to use it.
I hope this will remain a permanent part of the Benchmade Bugout line-up as it really is superb.

Knife Review: Spyderco Enuff 2

In this Spyderco Enuff 2 review, we will take in all the details of this fixed-blade knife. Enuff 2 is an expansion of the Enuff platform, designed by Spyderco’s Sal Glesser and originally created to emphasize the first few inches of the edge nearest the handle where most of the work is done. However, how much blade is “Enuff”, is a matter of opinion. For users who like the Enuff platform, but wanted just a bit more blade length, there’s the new Enuff 2.

Review Videos

Starting with a short format sixty second review:


Onto a full video review covering many more details:


A few more details:

What’s in the box?:
As you would expect from Spyderco.


A good look round the Enuff 2 sheath- Things to look out for here are:
Formed of two molded plastic sections held together with metal eye rivets, the sheath is very slim. The belt clip makes the whole sheath quite a bit thicker, but can be removed easily if you are packing the knife away.
Out of the box, there is a secondary retention option of a leather strap. With the post that holds the end of the leather strap adding further bulk, this strap and its post are also easily removed if not needed.
The belt loop has a nice one-way system to prevent it accidentally coming off your belt. The sprung loop curls back under to catch onto the bottom of the belt and stop it pulling off.
The molded sheath lips grip the handle firmly making the extra strap redundant unless you want a secondary retention on the knife.


A good look round the Enuff 2 – Things to look out for here are:
Starting this gallery off with the tip protector on the knife; it even has the Spyderco logo on it! (which you will discard, but just saying)
This Enuff 2 has the full Spyderedge serrated edge. Keeping the Enuff 2 slim but with a very secure grip, it has the distinctive Spyderco FRN scales with unique grip pattern.
A generous section of the blade spine has jimping for the thumb to grip.
Flipping the knife over reveals a few differences form one side to the other. The handle screws being one of these, where on the reverse side they are torx screws, compared to the blank heads on the ‘front’. Also clear is the fact the Spyderedge is a chisel grind, so one side of the blade has no edge bevel at all, which is why the Spyderedge is so effective.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.

The blade is made from VG-10 steel.


The Factory edge up close:

As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.

This gallery shows both sides and sizes of serrations with the chisel grind clearly evident.


What is it like to use?

This is the first Enuff knife I’ve used, so I can’t comment on the original Enuff. Even the longer Enuff 2 is still a compact fixed blade. Having such a flexible sheath means you can change things around, add alternative mounts, or strip it down to basics to keep it as slim and light as possible.

For me the full Spyderedge makes this more of a backup knife. Depending on your typical cutting tasks you might want the serrated edge for a lot of fibrous cuts, but for me this is a less common type of cut. Again, in this instance its advantage of being able to go without maintenance for a long time and still cut well is pushing me towards being an excellent backup knife. The plain edge version would be a great daily use tool.

A slight disappointment is the finish around the exposed tang which is not up to normal Spyderco standards. It might be this example, or a characteristic of the line. There is zero impact on performance, just on aesthetics.

Another observation is that the Spyderco Spyderedge on this knife is effectively a right-handed edge (the plain edge version would not have handedness), although everything else about the Enuff 2 is ambidextrous.

It is slim and light, and the Enuff design principles still hold true of the handle. I take XL size gloves, but the Enuff’s handle is still big enough for a firm and stable grip; it is not just the blade that is ‘Enuff’.

Light Review: Fenix E35R and E03R V2.0

Fenix are updating and upgrading two excellent EDC lights. The E03R V2.0 and E35R build on their predecessors and raise them to a higher level. Join me in this review of the Fenix E03R v2.0 and E35R to see how they perform and what improvements have been made.

Review Videos

For the E03R V2.0 first a short format sixty second review:


The short format sixty second review of the E35R:


Onto a full video review covering many more details of both:


What is in the box?:

A brief look over the contents of the box for each of these lights. Starting with the E03R v2.0 in its plastic clamshell inner. To remove the E03R V2.0 from the package needs the plastic tie that comes fitted through the lanyard hole. Without this you can’t get a grip on it ton pull it out of the very tight fitting packaging. It comes with a USB-C charging cable, small split keyring and instructions.
The E35R slides out of the outer cardboard box in a plastic tray. This comes with the battery already fitted, a USB-C charging cable, wrist strap and spare o-ring, plus the instructions.


A good look round the E03R V2.0 – Things to look out for here are:
Before anything else, here is a side-by-side of the original E03R and the new V2.0. You can immediately see the increase in size that allows for the uprated output and runtime.

At the front is the twin TIR optic for the main white beam (with central optic for the Red beam). On the side is a rubber port cover for the USB-C charging port. The power switch has an outer illuminated ring. The switch’s centre also has an indicator light for the state of charge. Details of the split-ring keyring are shown.


Taking a more detailed look at the E35R:

The side by side comparison to the original E35 is included in the video earlier in the review. Most noticeable is the addition of the USB-C charging port. Visually, apart from that, the E35R is almost identical to the E35.

In case you think it is faulty out of the box, Fenix has included a label to remind you to remove the in-transit insulator which protects the E35R from discharging in storage. For the E35R, it is the head rather than tail that unscrews to access the battery compartment. The contacts in the head include physical reverse polarity protection. In the tail is a single strong coil spring to keep the 21700 5000mAh cell in place. The threads are near-square in profile. There is a bronze detail ring round the TIR optic to match the colour of the power switch. To indicate the battery level the centre of the power switch lights up either solid, or a flashing. A steel pocket clip is included. One other addition in the update is the E35R now having a magnetic tail.


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 my wife won’t have one!

This gallery starts with the E03R V2.0 indoors, white and red beams. The red beam exposure is intentionally longer to show the shape of the beam, not the relative brightness to the white. However, for the outdoor beamshots, the exposure for white and red is similar, and is intended to show the red beam range is, of course, very limited.
Then the last two beamshots are the E35R, showing the very strong performance.


Batteries and output:

The E03R V2.0 has a built in li-po 400mAh cell, and the E35R runs on a removable 21700 5000mAh cell.

These images are the charging traces for the E03R V2.0 and E35R.


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.

When carrying out runtime tests, I always use a cooling fan to at least represent some of the cooling provided by your hands, and also the lower temperatures outside. Not using any cooling would be unrealistic.
In this run of the E35R, there were actually three power cuts that stopped the cooling fan running (the logging was running on battery), and this corresponds with drops in the output due to the thermal regulation ramping down the output.
The E03R V2.0 output is very predictable and stable and needs no further comment.
In the gallery, the second image has the times of the power cuts marked so you can see the corresponding drops in the E35R’s output.
Showing just the start of the output trace, the final image in the gallery shows the thermal regulation controlling the output.


The E03R V2.0 and E35R in use

Since Fenix first previewed the E03R V2.0, the debate has been based largely around if they have made it too big for a key chain light. Ultimately only you can make that decision, but I’ve found it a very good size. Being slightly larger it is more readily to hand (easier to get a grip on), and the added functions raise its usefulness even more.

I particularly like the ‘breathe’ modes of the E03R V2.0. A soft locator light which give a confidence that when in an unfamiliar place you can activate the breathe mode and then always be able to find where the E03R V2.0 is.

For a light that is going to be knocking around, and in and out of pockets, the timing of the power switch activation seems spot on. I’ve not had any accidental activations, and not really bothered with the lockout. It is good to have the option, but so far no warm pockets.

Between these two lights, the interface is effectively the same, so it is very natural to pair them. Of course the E35R is a single white light LED that goes up to an amazing 3000lm output.

At that maximum output the E35R does get hot quickly, and as shown in the runtime graphs, cannot be maintained – but take a moment and look at those graphs again. The E35R, with good cooling, is running at over 1500lm for an hour. This is a solid performance for a EDC pocket light.

I would prefer one lower mode on the E35R, but for most people, the available modes are going to work well.

With the power button being relatively low profile, it can be a bit hit and miss to find, especially with gloves. To get around this, what I do is to line up the pocket clip so it is opposite the power switch. You then use the pocket clip to index your grip and find the power switch without looking.

The original E35 was a good powerful compact light. It was just slightly smaller and a little lighter, and just enough light wrapped around a 21700 cell. Fenix have now managed to also squeeze in the on-board charging and magnetic base which are worthy updates and make the E35R a complete package.

So far, on testing the magnetic base of the E35R, I’ve found issues with slippage if put onto a smooth vertical surface. The magnet holds the light, but the finish on the tail is so smooth, if the surface is also smooth the E35R usually slips and slides down. If the magnet is holding a horizontal surface it is very secure. It is less about the magnet’s strength and more about there being enough grip between the E35R and the surface to not slide downwards.

‘New and improved’ is often a false claim, but for this pair of EDC lights from Fenix, it really is.

Gear Review: EDS II Screwdriver and EDC Wrench from BIGiDESIGN

BIGiDESIGN is producing so many awesome EDC tools, and in this review we are taking a detailed look at the BIGiDESIGN EDS II, the second, updated version of their unique Everyday Screwdriver, along with the BIGiDESIGN EDC Wrench a reimagining of an antique Swedish adjustable wrench.

Their original EDS, Everyday Screwdriver, was probably the first BIGiDESIGN product that I saw, and since then I bought their bolt action pen, a design that ingeniously adjusts to take most ballpoint refills on the market. Now I’ve been able to partner up the Bolt Action pen with the EDS II and EDC wrench making for an incredible EDC setup.

Video Overview

In this video we take a good look at a couple of lovely EDC gear designs from BIGiDESIGN. The EDS II, the second, updated version of their unique Everyday Screwdriver, along with the EDC Wrench, a small unique pocket friendly adjustable wrench.


What’s in the box; Part 1 the EDS II?:
For the three BIGiDESIGN products I have, the packaging follows the same layout. A slide out tray which has a compartment at one end that contains spares.


A good look round the EDS II – Things to look out for here are:
Overall layout of the EDS II is of an integral lock folding knife, but with a bit holder instead of a blade. A single thumb stud means this easier for a right-handed user. Explained in more detail in the video, there is a stop pin that both stops the bit holder arm in the right position when open, and also stops the spare bits sliding out of the front of the storage slot. The other end of the spare bit storage slot has a sprung ball to keep the bits in place. The integral lock action is easy to see as the bit holder is unfolded. Several magnets are used for keeping the spare bits in place and the main bit holder folded. In the EDS II an additional spare bit holder has been integrated into the lower section of bit holder arm. A total of four bits can be carried within the EDS II.


What’s in the box; Part 2 the EDC Wrench?:
Again, following the format of the other BIGiDESIGN products I have, the box has a slide out tray which includes a compartment at one end that contains spares.


A good look round the EDC Wrench – Things to look out for here are:
A reimagining of an old Swedish design, there is a sliding adjuster moved by a worm screw. BIGiDESIGN have added both a metric and imperial scale for setting the wrench ready to use. A low profile clip is fitted to the back and the EDC Wrench also includes a Ti bead on the lanyard. You can just see the slider retainer under the clip.


What it is like to use?

BIGiDESIGN have done something really special with the EDS, and now this updated EDS II, and given you not only a new experience of using and carrying a screwdriver, but one that is very practical as well.
It is not the smallest EDC bit holder available, nor does it include a ratchet, but instead it gives you a highly usable screwdriver with integrated bit storage for a total of four bits without needing anything else.
Having a swing-out bit holder extension arm, the EDS unfolds to a very practical conventional structure of handle, shank, and bit, so compared to many other small EDC screwdrivers it gives you a more usable tool.

That genius part of the design is mimicking an integral lock folding knife, having a thumb stud to swing the bit holder arm out of the folded position for one-handed operation. So satisfying to use!

However there is a little observation to note about how easy or difficult it is to open the EDS II. The arm’s retention in the folded position is due to a magnet in the body grabbing the bit that is in the bit holder. As you use the EDS II and swap bits around, you will find that a bigger bit, like the full size flat bit, is held by the magnet more firmly, so firmly it becomes very difficult to open using the thumb stud. Put a smaller bit into the holder and it becomes much easier to open again. So the bit you leave in the main bit holder arm changes the ease of opening the EDS II. I would have preferred that the arm retention was a detent (like a knife would use) or that the thumb stud had a bigger cut-out round it allowing more contact and an easier open.


Onto the partner tool here and the EDC Wrench, an infinitely more pocket friendly design than a standard adjustable wrench, there was one big flip for me, literally, in how I envisaged using it before actually getting my hands on one. That is the fact that with the adjustable slider being very much on one side of the tool, to use it and make contact with the nut, you have to flip it over so the ‘front’ of the tool is away from you (pocket clip towards you). Like this you can’t see the scale, and initially it just felt a bit odd, but is just how it works. Even with larger nuts, all except the very largest, you need to use it this way round.

Being a ring spanner, you do have to be able to pass the ring over the end of the job onto the nut, so can’t be used for certain jobs. If you hit those limits though, it is less likely an EDC type of job, so then you bring out the full size tools. Know the limits of your tools and don’t abuse them and you’ll get along just fine.


Talking of limits, and pushing them, the EDS II and EDC Wrench can nicely partner up for a bit more screw driving torque. There is just enough of the 1/4″ hexagonal bit showing to use the EDC Wrench to grip this and boost the turning force for stubborn screws. Not always possible, but if you have the space, this can save you having to go for bigger tools. In this case the EDC Wrench is used with the slider facing you as it needs to be this way round to grip that small section of the hex bit.

Both of these beautiful EDC tools are made from grade 5 titanium alloy and punch well above their weight, even more so together.

Knife Review: lionSTEEL H1

Join me in this review of the lionSTEEL H1, to take in all the details of this superb EDC fixed blade knife designed by Tommaso Rumici. This specific knife is a display model from IWA 2022 so might show a few imperfections. The H1 has a M390 blade, black G10 handle with grip ring, standard leather sheath plus also shown in this review with the optional Kydex sheath.

Video Overview

This video includes a close look round the H1, and then onto the measurements and specifications.


What’s in the box?:
As well as the standard H1 package, this review shows the optional Kydex sheath which is pictured next to the closed box. As standard, the H1 comes with the leather sheath and a lionSTEEL made keyring torx wrench.


A good look round the standard Leather Sheath – Things to look out for here are:
The H1’s standard leather sheath is packed full of features. Within the curved and flowing shaping of this sheath, it has a retaining strap secured with a press-stud, a ‘standard’ belt loop, along with two special loops that can be rotated and opened out to allow various belt or MOLLE carry configurations.


A good look round the optional Kydex Sheath – Things to look out for here are:
Giving you a more compact carry, the optional Kydex sheath has two special loops, like the leather sheath, that allow for various belt or MOLLE carry configurations, but without the fixed belt loop and retaining strap. The retaining strap is not needed due to the Kydex ‘clip in’ retention, so allowing for a much more streamlined sheath.


The details of the H1:
Starting off with the H1 sheathed in the leather sheath. A curvy knife in a curved and flowing sheath. Demonstrated in the last of the photos of the sheathed knife, if you are using the fixed belt loop, and if you wanted to tie-in the end of the handle tightly so it can’t catch on anything, you can swing the top loop over the end of the grip ring; not something you would do all the time, but an option.
The remaining photos take in details like the engravings, plunge line, jimping, grip ring finish, handle shaping/milling/texture, plus the overall lines of this knife.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.


What is it like to use?
Designed to combine the secure handling of the karambit’s grip ring with a knife blade much better suited to daily EDC tasks, this make the H1 an unusual shape that you might not immediately be drawn to.
Although I started with the two galleries in this section the other way round, I decided to look at the personal carry aspect first. Shown earlier in the review, the H1 can be MOLLE carried, so this is about carry directly on your person using the belt and additional loops on both the leather and Kydex sheathes.
For me the least successful carry is the standard drop belt loop. With the angles set into the sheath, the presentation is very awkward for me, and with the leather wrapping round the handle, re-sheathing the knife tends to result in cutting into the sheath each and every time. It is quick to deploy, but not to re-sheath.
Moving swiftly to horizontal carry and suddenly everything works much better. For the leather sheath you can mount it on your hip facing backwards. The leather sheath doesn’t really work for back carry, due to the retaining strap (this is where the kydex sheath really shines).
(Just to mention these photos are all for right-handed drawing.)
Last up is the kydex sheath on hip and back carry positions. Actually for the back carry I would have set the loops so that one was each side of the trouser belt loop to provide stability for drawing and re-sheathing. The lower profile kydex sheath is excellent, and shines in the back carry position.


So we’ve looked at carry, and now onto handling of the H1. Yes the H1 has a grip ring, but you don’t have to put a finger through it, you can also hold it like a standard grip and use the width of the ring to control the angle the blade presents. Worth remembering and not always putting a finger through the ring.
As you can see, though I take XL size gloves, the H1 is quite a compact knife. With the curve of the blade and the jimping on the spine, the H1 sits so well in the hand making it feel a simple extension of you.
Reverse grips are as natural as forward grip, and the ring is a size and finish that makes it super comfortable however you take hold of it.


I’ve always loved lionSTEEL’s leather sheaths, and the H1’s is a very good sheath. For me though, the optional Kydex sheath takes the H1 into a different league. I would recommend getting it. (If lionSTEEL could offer a sheath choice when buying so you could get the H1 without the leather sheath and just the Kydex one, all the better.) The slim H1 definitely benefits from the much slimmer Kydex sheath. This sheath also allows for ‘in pocket’ carry which the bulkier leather sheath does not.
Handling is where the H1 really excels with the versatile grip ring and curving handle and blade shape that fits into the hand beautifully. Between the H1 and H2 (the H2 which has a drop point blade), the sheep’s foot style blade shape presets the tip of the knife very well for point work, and the curved cutting edge slices easily.

Gear Review: Mjolnir III by Ostap Hel Knives

When it comes to EDC pocket jewellery, nothing beats a hand-made custom piece, and I’ve had my eye on the Mjolnir from Ostap Hel Knives for some time. Yes, Mjolnir is Thor’s hammer, and being capable of a knockout blow is very appropriate association, but of course the shape of Ostap’s Mjolnir is also like the old Norse symbols.
Join me in this review of the Mjolnir III from Ostap Hel Knives, the featured version is in carbon fibre.

Video Overview

This video is a detailed look at the Mjolnir III, and hopefully you can get a good feel for the quality of finish.


What it is like to use?
Without saying exactly how you might use the Mjolnir III (due to some more negative connotations), it is both EDC pocket jewellery and a self-defence aid.

The intended configuration for carrying the Mjolnir III is on its own with a lanyard, added for ease of getting it into your hand when needed. Shown here, it has the matching lanyard from Ostap Hel Knives which has a CF bead on the cord. With the CF version being so light, it has minimal pocket presence so can also feel a little difficult to home in on. So…

…picking up on the fact it has felt a little ‘detached’ from easily finding the CF Mjolnir III in my pocket, I wanted to try something a bit different and out there, and fit it as a lanyard stopper on another EDC item. In this case a slip-joint knife which already had a longish lanyard on it.
In this way, the knife provides the weight for easily finding it, and the Mjolnir III makes a fantastic ‘puller’ for getting the knife to hand, but also for then ease of getting the Mjolnir III into your hand.
Reversing the sense that the Mjolnir III is the lanyard stopper round to the knife being the lanyard stopper, and you can either allow the knife to hang out to the side, or take it into you palm while gripping the Mjolnir III between your fingers.
You can experiment with the lanyard length to see how it might work for you if you try this approach. Here the loose ends of the paracord are not yet woven into the lanyard to more easily allow adjustments before making the final configuration.
It has worked for me, it might work for you; try it before completely dismissing the idea.

Regardless of how you choose to carry it, the Mjolnir III is a pleasure to handle and carry. Despite there being no moving parts, it can be a worry-stone or fidget toy, as well as having an actual serious purpose – definitely worth the investment in a quality piece.


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 that covered in the review.

I’m trying something slightly different and starting with what doesn’t work so well, so I can finish on a more positive note.

Light Review: Nitecore TM20K – 20,000 Lumens!

Nitecore’s Tiny Monsters have always been punchy performers, from the first one I tested, (the TM11) all the way through to another Monster light that is Tiny compared to its output. Join me in this Nitecore TM20K review, 20K being the 20,000 Lumens, yes, 20,000 Lumens output from a palm sized light. As well as a look round the TM20K, this review includes output measurements, runtime graphs, and beamshots to give you the true story of its performance. It really is a Monster!

Video Overview

This video is an overview of the TM20K with a first look over the light before we get onto more details and the measurements.


What is in the box?:
This gallery shows the TM20K’s packaging and what is included. The holstered TM20K, a USB-C charging cable, a lanyard, and a thin cord for threading the lanyard.
There is also a look over the belt holster and how the top flap opens.


A good look round the TM20K – Things to look out for here are:
First, do not turn the TM20K straight on out of the box! There is a blue protective plastic film over the lens that will melt and make a mess of the front of the light, so make sure to take this off.
The body of the TM20K is a single piece, and this is not broken by any battery doors, as the TM20K has a built-in battery and is USB-C rechargeable.
The lanyard hole is next to the charging port and mode switch. On the opposite side to the mode switch is the selector toggle switch with lockout setting.
One of the flat sides has a wide steel belt clip. Also shown are the small heat sink fins and grip knurling.
On the tail of the TM20K you find the power button, tactical switches and the charging port.


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 my wife won’t have one!

For the beamshot comparison I used three output modes. The Daily mode ‘Floodlight’ and ‘Spotlight’ special output levels plus the ‘Turbo’ 20,000 Lumen mode.

Indoors are only the ‘Floodlight’ and ‘Spotlight’ modes as Turbo is too bright. Then moving outdoors with the same modes (around the 2,000 Lumen level), and then with the same exposure, the Turbo output. 20,000 lumens really lights things up!!


Batteries and output:

The TM20K runs on a built in battery made of 2 x 21700 4800mAh cells.

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.

19 XP-L2 LEDs to blast out 20,000 lumens.

When working with any lights with an output over 5,000 lumens, I need to make modifications to the integrating sphere. For the TM20K, due to the extreme output and small size, it is limited to short bursts of the 20,000 lumen Turbo output. So the output table is a little different to most of the reviews I carry out.

Half the table is normal, then where it starts to list an ND filter, this is a ‘neutral density’ filter that simply cuts the light reaching the sensor by approximately 90%. Reference readings are taken to ensure the filter factor is correct, and a set of measurements were taken. With the short 8s burst of Turbo, several readings were taken and averaged. All of this is included in the table.

The graphs in this gallery show a few different things. First is a trace of the charging current consumed when charging the TM20K.
Next up is the runtime trace for High output. Due to the Turbo output being a burst mode only, for the full runtime, the graph shows the output for the high output level.
Now we have two copies of the same graph, the first shows all the traces taken to check the behaviour during the ANSI 30 second measurement time.

Shown first is an initial ‘High’ ANSI output trace (Section 1), then the Turbo button held for 30s (Section 2) where the output drops to High after 8s. Section 3 shows what happens when you intentionally use Burst, Burst, Burst until the TM20K won’t output Turbo any more.

As the ANSI output should be measured at 30s, the 8s Turbo output would mean ‘ANSI Turbo’ measurement was 3611 lm, so this means we can’t actually state an ANSI Turbo output and instead I have gone for ‘max at switch on’ for the value of Turbo, and this is what was used in the output table.


The TM20K in use

20,000 lumens in the palm of your hand, here it is:

And as a starting point I have to say the TM20K is scary bright! As well as that it heats up so quickly on Turbo you really know this is pumping out the power.

Being about the size of a 2x 18650 light used to be, the TM20K is noticeably heavier and more dense than this older class of light, a sign it is packed with performance.

The supplied holster is very nicely made and is a rigid style with flip-top lid style opening. When belt mounted you need to pull the holster body away from you to allow the lid to hinge open far enough to get the TM20K out. This might have worked better flipping open away from you. The magnetic closure is a nice touch and allows for silent opening (without the ‘tearing’ sound of Velcro).

One of the most important features for a light like this is the lockout; yes the ‘not outputting any light’ feature. Absolutely critical as the output is so high, if contained it will be dangerous.

Lockout should always be easier to activate than to deactivate, and Nitecore have made it very easy. Slide the toggle switch to the padlock and once it has been there for 2s the TM20K is locked.

While locked, if you slide the toggle to 1 or 2, the power button flashes five times to let you know it is locked. Unlocking requires two switches to be used at the same time. Holding the mode switch down as you slide the toggle switch from lockout to position 1 or 2 with the beam turning on briefly to let you know unlocking was successful.

All of that to talk about the TM20K not outputting anything, well, you will be very happy about this feature.

In terms of handling and the interface, although the TM20K lists ‘tactical’ modes, the layout of buttons and ease of access to them would not be my choice for use in a pressured situation. General use, and even search and rescue use, but not reaction or time critical scenarios where you might miss buttons or press ones you didn’t mean to.

Onto those 20,000 lumens. You get a burst of 8s at this level. If you immediately reactivate Turbo, you can do this two further times (three times before a cooling off period) where the thermal protection prevents the TM20K from going above High mode even using the Turbo button. So from cold, 24 consecutive seconds of 20,000 lumen output. Measured and confirmed as shown in the output table and graphs, all from a palm sized light. This is seriously impressive.

Going to the other extreme, I would have preferred a mode lower than 350lm. This is the ‘ultra-low’ mode on the TM20K. Even if you are breaking out the Tiny Monster, there is still a practical lower level for every day use and 350lm is too high, so this is a light to bring out when you want a lot of light.

Considering the size, that performance on High giving a hour of solid output, 45 minutes of which is over 3000lm, does make this a workhorse, even if you ignore the Turbo output.

Not forgetting my previous comments about the tactical mode, the momentary output in this mode is great for searching especially when other people are around and you don’t want to blind them.

My preference is always for removable/replaceable batteries, but the other side to this is the guaranteed performance of the cells chosen by Nitecore to power this Tiny Monster, and the simplification of the design as it doesn’t need a battery door. Being a super high performance light, the cell characteristics are critical, so we can take the built-in cells as a positive point.

20,000 lumens is shocking and astounding from a pocket sized light, well done Nitecore.

Knife Review: Extrema Ratio SATRE – Special Report

The Extrema Ratio Satre is a pocket-sized, light and extremely tough fixed blade knife, designed in collaboration with Daniele Dal Canto, a Master Advanced F.I.S.S.S. instructor. In this special report review of the Extrema Ratio Satre, I am able to carry out a special set of tests to quantify the edge apex stability (resistance to rolling) in a direct comparison of the two steels the Satre is available in, N690 and S600, as I have all three versions of the Satre available to test, the standard Black and Satin (N690) and the S600 version at an super hard 64 HRC. This special report also include two videos, an overview and detailed measurement, plus one showing the steps of the edge stability testing (SET – Structural Edge Testing).

Video Overview

This video is a detailed look at the three SATRE Models, from handling to technical measurements, hopefully something for everyone.


A few more details:

The videos show all three versions, but as the dimensions, shape and function are all identical, the galleries here show the standard Black Satre.

What’s in the box?:

As well as the knife in a bag with desiccant, there is a QC certificate, care instructions and warranty information.


A good look round the Sheath – Things to look out for here are:

The small and neat Kydex sheath arrives with a neck lanyard, nicely laced through the eye rivets that hold the Kydex halves together. These eye rivets allow for other mounts to be fitted such as the ULTICLIP. The sliding adjustment toggle also serves as a safety break-away. There is a drainage hole at the blade tip on one side.


A good look round the Knife – Things to look out for here are:

The Satre knife consists of a single piece of steel with no other material attached to it (ignoring the small cord lanyard). Despite that simple construction, Extrema Ratio have managed to pack it full of character and clearly identify it as one of their designs. The distinctive first finger grip is shaped into the tang along with the small cut out for weight reduction. Plenty of jimping is provided for various grips.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.


Structural Edge Testing:

Added in 2019 are results from the Edge On Up Structural Edge Tester (SET) to measure the resistance of a knife’s edge to rolling.

The key factors for the SET results are:
Series 1 Degradation – how much damage the edge suffers from one edge rolling cycle. The damage is represented by an increase in the BESS ‘C’ score. (Averages also shown for A and B)
Series 2 Degradation – how much damage the edge suffers from one further edge rolling cycle. (Averages also shown for A and B)
Degradation after strop – has the edge been permanently damaged/chipped or can it be recovered with stropping? A negative number means it actually improved from the starting figure, suggesting there may have already been some rolling of the edge before testing. (Averages also shown for A and B)

First a video of the testing process, then the table of results.


The following results do show a clear increased resistance to edge rolling for the S600 steel. In fact after two ‘series’ the edge has rolled only a similar amount to the N690 blades have after one ‘series’. This is a clearly stronger and more stable edge apex.
Often this extra resistance to edge rolling can be coupled with a more brittle edge, yet the S600 recovered better than the N690 after stropping. (If it was brittle the edge can chip when stropping and give a high BESS measurement.)
In this table, are the individual results for all three, plus a combined N690 set of totals at the bottom.
The figures in bold in the first column are averages for the single measurements.


The Factory edge up close – NEW FOR 2022!:

Followers of Tactical Reviews will know my views on factory edges, but to recap:

Anyone using a knife will need to sharpen it. That first factory edge is just like the first tank of fuel that a new car comes with (or first charge of the battery).
A good factory edge is a ‘nice to have’ but not a ‘make or break’ for a good knife, as you will be putting your own edge onto it soon enough.
The factory edge does however indicate the care a knife maker has put into the final finish.
It is for this reason Tactical Reviews measures factory edge sharpness and specifications, and includes this information in the detailed technical testing.

As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.

In these galleries are each of the three versions with a before and after SET testing image. The edge rolling is just visible, but not easy to see.

Black N690


Satin N690


S600


What is it like to use?

It’s just one of those superbly useful knives. An easy size to carry and use, or keep as a backup. The size of the knife is similar to a medium sized folder, but being a fixed blade makes it super tough and a real working blade.
Here I’m showing it in an un-gloved hand (a hand which takes XL size gloves). It is compact, and doesn’t fill my hand, but the finger groove provides a really secure grip with the jimping (especially the thumb jimping) giving confidence.


With it being a compact blade and one without handle scales, the knife is capable of much harder work than you can comfortably manage with the bare blade tang in your hand. This design keeps it very low profile and really does make carrying and storing as a backup so much easier than a knife with wider handle.

Either in the pocket, or hanging around your neck the Satre is slim and unobtrusive. I can make this comment, not just based on one example but on all three – the Kydex action is spot on. The sloped shoulders of the sheath are just right to push on to release the knife, and the blade clicks out without a fight. This action is almost identical across all three and holds the blade securely without struggling to sheath or unsheathe it.

As seen in the SET testing section and video, the S600 steel is noticeably tougher. As with any higher hardness and higher wear resistance steel, you will notice the S600 is much more difficult to sharpen, and will need a suitable sharpener. This always makes for a dilemma for field use for me. As much as I love a longer lasting edge, if I might need to rely on one knife and might need to sharpen it in the field I would want to be able to sharpen it more easily and if required with natural stones rather than specialist sharpening equipment. This is just a consideration, as for many the longevity of the edge it already has may be more important than being able to sharpen in the field.

With a blade this thick (compared to its length) it doesn’t slice as well as a finer pocket knife blade would, but this blade is one you know won’t let you down if you need to work it hard. If you put one aside as an emergency backup blade, you know it is going to serve you well.


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.
