Knife Review: TRC M-1SL

6 October, 2024

Join me in this detailed review of the stunning new TRC Knives M-1SL; a carefully considered evolution of the TRC Mille Cuori.

Adding to the “M” line from the Lithuanian manufacturer, the M-1SL is designed to meet the needs of a wide range of users involved in various outdoor activities. A sturdy tool that is well suited to bushcraft, camping, hunting and much more. It’s similarity to the Mille Cuori or M-1SLG, is because it is a development of that knife.

The spine has edges sharp enough to strike sparks from a ferro rod, but not sharp enough to cut you. Like all knives in the “M” line, the handle has deep jimping / grooves on the handle for excellent grip and handling. Made from premium BÖHLER M390 MICROCLEAN steel, the blade is highly corrosion resistant and really holds its edge.

(Review Videos now at the end of the review.)

What’s in the box?:
Setting the theme of ‘attention to detail’ from the first moment, TRC start as they mean to go on with the M-1SL’s presentation box. You already know this is going to be good.
As well as the sheathed knife, there is a specification card, metallic sticker and rubber patch.

A good look round the M-1SL’s sheath – Things to look out for here are:
As important as the knife it carries, the sheath manages an understated simplicity, yet is packed with features and functions that allow it to do its job brilliantly.
It is a rare thing to not be able to find an unfinished edge or corner. TRC Knives have delivered this, with every edge, corner, joint, bend, and fixing being smooth and refined. I have not found a single part of the sheath that could benefit from a tweak or shave; TRC have done all of this without missing anything.
If I had to be picky, I feel the drainage hole may not be as free flowing as if it ran downwards instead of sideways. However, where it is positioned is very neat and keeps the lower edge of the sheath streamlined.
The hollow rivets used to hold the two sheath halves together are completely smooth on both sides, so there is no wear to cord threaded through them. It comes with an elastic cord in place that is ideal if you want to secure the end of the sheath to your leg, as the elastic allows you to move freely.
Designed into the sheath is a fully adjustable knife retention, on both sides, not just one. This tension was set just right out of the box, but will wear in over time, and if ever needed, you can tighten it. If you prefer less of a grip on the knife you can also back it off to suit.
To swap to left-handed, you need only remove two bolts and pop the belt loop hanger on the other side of the sheath.

A good look round the M-1SL knife – Things to look out for here are:
Yes you might well recognise that distinctive blade shape from the TRC Mille Cuori, and in the M-1SL it is brought to you in a lighter-weight version. A drop point blade with bevelled swedge, plus thumb rest on the spine just forward of the handle, all combine to give this blade its identity.
Again the attention to detail doesn’t stop, the finishes are crisp without being sharp. The corners of the swedge bevels are just a little sharper than the corners of the thumb rest. Those slightly sharper corners on the swedge will scrape a fire steel very well yet are completely safe for your hands or gloves.
With the edge finishing in a sharpening choil next to the finger guard, not only does this complete the cutting edge, but provides you with the ‘fine work point’ (that I use this end of the cutting edge for).
The very front of the handles are angled to guide the knife into the sheath, this also gives good access to the cutting edge for all types of cutting task.
There is plenty of grip from the G-10 handle scales, that also combines with the jimping at the front and back of the handle to ensure a firm hold on the knife. Flared hollow rivets secure the handle scales and provide lanyard/lashing points.

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 M390 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?
I may have said ‘refined’ and ‘attention to detail’, or words to those effect, a few times in this review; this seems to be a feature TRC Knives are widely recognised for, and is clearly evident in the case of this M-1SL.
This doesn’t happen by accident, and is only as a result of hard work and caring about your products. When meeting Andrius Tricius (founder and head designer at TRC Knives) to talk about the M-1SL, his passion for the design and quality of finish came across immediately. He was listening closely to any and all comments I made about the knife, genuinely interested in understanding how his designs work for all users; clearly someone passionate about making the best possible knives.
Fitting into a general utility knife size category, the M-1SL is a super practical knife that is big enough for most tasks and small and light enough to be easy to carry – a no-brainer when it comes to picking out a daily use fixed blade.

With 4mm blade stock and a full tang the M-1SL is seriously robust so can take on tougher tasks as well. Chopping and batoning are no problem with the blade length just needing good technique and knowing when not to over-reach and risk the blade getting stuck.

For me, one thing I would prefer would be for the sheath to be smaller. With the typical two piece Kydex construction you end up with a slab of sheath which increases the overall carry size. The knife is a great EDC utility size (and super strong), but the bulk of this type of sheath does make me think twice on occasion. Could you still have such a functional sheath with retention tension adjustment and tying points with less bulk?
Perhaps a small detail, but worthy of further mention, the dedicated thumb rest on the spine; this allows you to comfortably put your thumb directly behind the cutting edge and apply maximum cutting force directly towards the cut. The power and control this cutting method provides is important, and though you can do this with all sorts of knives, the M-1SL has the thumb rest designed into the spine of the blade. Having this feature increases comfort and control exactly because there is a specifically shaped section on the spine.
Frequently, when living with a knife, I find something that is a bit ‘off’, a sharp corner, or something I want to tweak; so far with the M-1SL I’ve not found anything I want to tweak – I’d say this speaks volumes.
It also is certainly a difficult knife to put down, being pleasing to hold as well as use.

Light Review: Nitecore EDC33 and EDC35

28 September, 2024

This is a detailed review of the Nitecore EDC33 and EDC35, two new Tactical EDC torches / flashlights featuring the NiteLab UHi 20 Max LED and UHi 40 MAX LED respectively. Each are powered by a built-in li-ion battery with USB-C charging port under a rotary cover.

The UHi MAX LEDs combine a small but high-intensity main core with 8 auxiliary cores arrayed together into a single LED, offering long-range coverage, extreme brightness and the ability to seamlessly switch between spot and floodlight.

The “Lumin Shield” mode blasts an stunning 4000/5000 lumen maximum output wall of light.

Onto a full video review covering many more details:

What is in the box?:
With the EDC35 also having a belt holster, the unboxing is a bit different as the EDC35 arrives in the holster. The EDC33 doesn’t have a holster and comes in a slide out plastic tray.

A good look round the EDC35 belt holster – Things to look out for here are:
This is a semi-rigid type of holster, so when empty is the same size as when the light is inside it. There is a magnetically secured flip-top opening which hinges towards the belt loop.
A D-loop hanger, fixed belt loop and Velcro closing belt loop provide options for mounting/carry.

A good look round the EDC33 – Things to look out for here are:
The smaller of the two models on test here (based around an 18650), the EDC33 is a straight tube layout with generous size pocket clip. A set of four battery charge level indicator lights sit just beneath the rotating USB-C port cover. The EDC33 has a sliding toggle lockout switch and a two-stage forward-clicky tailcap switch. The EDC33 uses a NiteLab UHi 20 Max LED.

A good look round the EDC35 – Things to look out for here are:
The larger of the two models on test here (based around an 21700), the EDC35 has a head larger than the body to allow for a bigger reflector to accommodate the higher output, and also includes a generous size pocket clip. A set of four battery charge level indicator lights sit just beneath the rotating USB-C port cover. The EDC35 also has a sliding toggle lockout switch and a two-stage forward-clicky tailcap switch. The EDC35 uses a NiteLab UHi 40 Max LED.

The beam

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

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

Exposures are not identical throughout the galleries – images are intended to show the beam shape and impression of what you see, rather than a brightness measurement.

EDC33 Beamshots:
Both for indoor and outdoor, the spot beam is shown first, then the ‘Lumin Shield’ beam.

EDC35 Beamshots:
Both for indoor and outdoor, the spot beam is shown first, then the ‘Lumin Shield’ beam.

EDC33 and EDC35 Beamshots:
This gallery uses all the previous images but groups them into comparative pairings for the EDC33 then EDC35 with each type of beam. As before this is the spot beam shown first followed by the ‘Lumin Shield’ beam for the indoor images and then the outdoor.

Batteries and output:

The EDC33 has a built-in 18650 cell and the EDC35 a built-in 21700 cell. Parasitic drain cannot 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.

This table compares measured and specified outputs for each mode.

Runtime traces for each model on ‘High’.

Also included in the gallery are the charging capacity measurements after recharging from the end of the runtime testing (show in Wh and Ah).

The EDC33 and EDC35 in use

These lights are BRIGHT! The Lumin Shield does exactly what it promises and blasts a wall of light. The power output is made all the more obvious by the heat generated in the head of each light, especially the smaller EDC33 where the head heats up very fast using Lumin Shield. The EDC35 has more mass and the heating is less immediate which does give you more working time with this mode before it becomes uncomfortable in a bare hand.

This leads me to suggest the main choice between the EDC33 and EDC35, with this being how much you want to use the higher or maximum outputs. The EDC35 has more mass to manage the heat produced, and larger battery capacity.

The next gallery shows the size of each in the hand (I take XL size gloves). In terms of weight, the EDC35 is 150% the weight of the EDC33, plus the holster and general bulk. This weight and size penalty gives you a longer runtime and ability to make use of the higher output for longer.

The choice of more comfortable use of maximum output, or ease of carry will then guide you to the right choice for you.

Though the EDC33 heats up fast on Lumin Shield, it does still give you a wall of light in a compact package, so as a backup this is extremely capable.

For my own use, I use lower outputs about 90% of the time, so this leads me to one of my main observations about using the EDC33 and EDC35, and that is it takes al lot of practice to reliably avoid triggering the Lumin Shield when in fact you really wanted the ultra-low output. Linger just a little too long on the tail switch, and instead of 5 lumen you get 4000 or 5000, or while trying to avoid that you fail to turn it on at all.

Clearly, the ‘Lumin Shield’ wall of light is the headline tactical defence function of these lights, and for that they are excellent. This mode is easily activated (almost too easily) and in the half-lockout is the mode still available. Take this as the primary function and you can then consider the lower outputs as a bonus.

To best manage the accidental activation of the Lumin Shield, I make sure to briefly close my eyes when trying to activate the daily modes, especially when I want the ultra low, and if I do accidentally unleash the 5000 lumens I don’t getting the full effect as I will have let go of the switch before I open my eyes.

Likewise for switching off when using lower modes, I don’t touch the tailcap, instead using the lockout switch to turn it off completely safely, as this will definitely not activate any other output mode.

Making the minor adjustments to how you operate the EDC33 and EDC35 allows the lower mode use to be smoother and not jar, and you still have the potential defensive wall of light ready to go if needed.

Gear Review: Wiley X Trek Sunglasses

31 August, 2024

The Trek is a model which introduced yet another innovation from Wiley X, the removable side shield. This allows for a flatter and more traditional style of frame without sacrificing the Wiley X feature of meeting EN. 166 & ANSI Z87.1 safety standards.

In this review, the version of the Trek on test also features the Wiley X CAPTIVATE lens which I previously covered as a separate in-depth review – Wiley X Captivate Lenses (Models shown – Contend, Peak and Breach).

As someone who relies daily on the best quality sunglasses, but that also needs EN. 166 & ANSI Z87.1 safety standards, Wiley X has been my go-to brand and has never let me down.

Since first finding Wiley X many years ago, I’ve not looked back when it comes to eye protection, lens quality, fit and style.

Review Videos

Starting with a short format sixty second review:

Onto a full video review covering many more details:

This video also contains useful information on a slight difficulty with the removable side shields and explains how to prevent the issue.

A few more details:

What’s in the box?:
As these Trek glasses have the Captivate lens, they come in the Captivate version of the outer packaging. All the functional parts have been fitted into the case, with just a sticker accompanying the case as you unbox it.
Opening up the zip up case, and inside are the glasses inside a cloth bag, plus a much smaller cloth bag (containing one set of side shields), a neck strap, permanent side shields and some information leaflets.

A good look round the Trek – Things to look out for here are:
With the Trek glasses unpacked, this gallery takes you round views from all sides to show their flatter traditional profile. A closer view of the hinge and fittings for the side shields is included.

The removable Side Shields – Things to look out for here are:
First in this gallery are the two types of side shield with a scale to show their size. On the left is the ‘removable’ type and on the right the ‘permanent’ with separate fixing pin.
Before fitting the removable shield, it is shown next to the arm so you can see how it will fit in. Then the shield clipped into place.
Once the side shield is fitted, when folding the arms, it does interfere with the folding action and also sticks out a little. The knock-on is that it makes getting them into the case more difficult. You need to stretch the zip out to close the case, but you can still fit them in.

What it is like to use?

During testing I immediately found a feature of the side shield fitting that make the ‘removable’ shields, not removable. In fact it would be easier to remove the permanent side shields as there is a fixing pin you can pry out. However, there is a way to prevent this with a minor modification that is best done before you fit them. Wiley X are great at listening to feedback and are making a change to improve this for future versions.

The detailed video at the start of the review also includes information of a work-around you can use to make the removable side shields removable. Using this modification, I have them working as I would have expected, so watch the video to find out how to prevent it becoming an issue for you.

With my specific requirements, as well as the actual physical protection the side shields offer, I also wanted protection from light, so I have customised the side shields I use by blacking them out with spray paint.

Being careful to mask the parts that attach to the arms so the fit would not be affected, I then used a normal metal paint spray (I had a little left over from another job) to give them two coats. Spraying the inner surface resulted in a matt side towards me and the outside looking glossy. Fitting these customised shields to the Trek, and they blended in perfectly while providing the light blocking I need. I would not hesitate to do this again, as it has transformed them for me (unless Wiley X decide to make a black version of the side shield).

This gallery shows the bare Trek, and then similar views with the custom blackened side shields.

Being so used to the wrap around shape for sunglasses, the Trek model gives a really nice alternative styling with a more traditional look. The latest in eyewear technology with classic styling. A great combination.

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.

Gear Review: Halfbreed Blades MFE-01 Rhino Tool

7 July, 2024

This detailed review of the MFE-01 (Rhino Tool) from Halfbreed Blades takes a close look at a tool bursting with design intent. A specialist Method of Entry (MOE) / Breaching tool that was developed for the Special Operations Engineer Regiment (SOER) by Halfbreed Blades’ sister brand Hardcore Hardware Australia, and is a NATO stock numbered tool.

Multi-function design make the MFE-01 ideally suited for prying, digging, chopping, hammering, cutting, smashing rock, defeating locks, smashing windows, breaking and raking windscreens and as a climbing aid. The entire tool is overbuilt for outstanding longevity and is made from 8mm Bohler K110 (D2) tool steel and G10.

The MFE-01 is widely in use globally amongst Military and Law Enforcement groups, and is highly sought after by civilian users thanks to its highly functional design.

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?:
Considering the intent of the MFE-01 tool, and its likely deployment, the presentation box was a surprise, and a substantial one.
The box is shown with a Hardcore Hardware MILF folder and the one with my hand sticking into shot isn’t a mistake, but to give you some scale to appreciate the size of this box.
Opening it up and you have your fill of Halfbreed Blades contents; a rubber patch, catalogue, information sheet, certificate of authenticity and sticker.
Putting these aside we get to the high density foam liner precisely cut out for the sheathed tool. The optional belt loop sits next to the main tool with the extra fixing screw tucked underneath it.

A good look round the Rhino Tool’s Sheath – Things to look out for here are:
I’ve said it before and will say it again, the sheath or carrier for a tool is as important as the tool it carries, not least as if it fails, you have no tool at all.
The MFE-01’s sheath has a lot to look at. First in the gallery is a closer view of the belt holder. The Rhino tool is quite a weight to have on your belt, so I’ve not opted to adopt this myself, but it is a strong and serious option if you want to carry it on a belt. Of course you might also have a pack where this it the best way to attach it so it might not be used for a belt anyway. It is a ‘DOTS’ belt holder with belt width setting, lock, release button, and can be mounted horizontally or vertically.
The sheath is Kydex with metal hollow rivets holding the halves together. Once clicked into place the tool stays put, but for maximum security there is a retention strap with a pull-the-dot press stud.
For the MOLLE or belt loop fixings, the nuts are captive in the Kydex, so all the fixing holes are permanently threaded and ready to use.
The rigid DOTS MOLLE mounts are fast and easy to use. The mounting screws for the full MOLLE mount are hidden under the two MOLLE straps, so you need to partially disassemble the mount to access the fixing screws if you want to replace the mount with the belt loop.

A good look round the MFE-01 Rhino Tool – Things to look out for here are:
And here we have the MFE-01 Rhino tool. A slab of 8mm D2 steel with G10 slab handles – so take from that it is flat in overall form. When we get on to the in-use results, this is a factor in performance, but the main reason for the flatness is the requirement of being carried and not catching, digging in or otherwise impeding the user when they are not using it.
The prying end of the tool has a straight wedge with nail puller split. I specify a ‘straight’ wedge to indicate the pry tool does not have a levering bend, but is straight.
Just next to the pry tool is a lashing point through the shaft. The G10 handle slabs start just above this and are screwed onto the shaft. A slightly closer view shows the G10 layers.
As well as the round lashing hole, or lanyard hole, the handle has long slots that both reduce weight and can also have cord wrapped through then.
Moving up to the head, one of the main features is a versatile ratcheting claw; the jimping on the top allows you to work the claw into position step by step, giving a powerful ratcheting action.
Partnering the claw is a compact splitting head. This is not a axe for chopping wood as you might in bushcraft, but a powerful and focused striking point for splitting and smashing. The head is small for maximum striking power and the angles wide for edge stability and endurance.

The Blade and Handle – Detailed Measurements:
This section is from knife testing measurements, and was carried out to give some of the aspects which are also relevant to this tool’s effectiveness and balance. Bear this in mind when looking through the values which are intended to assess knives not tools like this.
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 D2 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.

Like the knife parameter measurements, this was included out of interest for the small factory cutting edge on the splitting head.

What is it like to use?

Let’s not forget, this is a military tool with a NATO Stock number, so when we look at this as a tool in itself, and for general use or prepping, the compromises of certain functions are absolutely intentional within the overall design.
This tool is intended to be carried into conflict, and, critically, to minimise how much it will impede the user’s movement when carrying it. This is a vital factor to keep in mind while assessing the tool in comparison to dedicated, larger and less easy to carry tools.

When considering the uses of a tool like this, it occurs to me that though this is termed a MOE or Method of Entry tool, this is also a Method of Escape/Exit tool. You might want to breach a door to enter or exit.

Basic ergonomics are of an easy to handle mid-weight hand tool. The G10 handle scales bulk up the 8mm steel to make for a comfortable hold. I’m only showing three of many possible grip positions here. In use you will grip the entire head as a handle when prying.
The action of sheathing and unsheathing is of rotating the head out of the sheath with the claw being the pivot point. Re-sheathing starts with hooking the claw into its socket and rotating the head into place.

Starting off this next gallery are a few prying examples. This is actually the first completely straight prying tool I have ever used (of a good size, not counting pocket prybars). All dedicated prying tools have a bend or curve to allow levering and room for the handle to move and the pry head to lift. With a straight pry tool you typically need to use a different technique. Some prying tasks may have plenty of room to move, for example prying a crate open, but others, like lifting nails usually end up with running out of room to lever them out. A simple technique to eliminate this issue is to place a spacer piece under the pry tool and use this to lever over and provide the same lift as a bent pry tool. If you need more lift, add another spacer.
The claw tool has so many potential uses that I haven’t been able to try, from piercing, smashing, lifting, raking. My testing was of controlled lifting and applying force where I could not grip with my hand. Unfortunately the day at the wreckers yard didn’t work out, so I can’t report on vehicle tests.
Remembering the splitting head (not axe head) has a wide geometry for durability, you need to wield it for a smashing/splitting action more than chopping. It made quick work of dry pallet wood, a good indication of providing you with effective destructive power.

Assessing and testing this tool in more of a prepper, survival, and enthusiast’s point of view does slightly conflict with some of the military design requirements. The design, and its capabilities, are all specifically designed to meet a military brief. In this, the design of the MFE-01 meets the requirements, and a compromise in one aspect is due to a more important requirement.

Don’t compare the Rhino tool to a normal crowbar, axe, hammer or any other dedicated tool, instead it is a versatile and tough multi-tool for SHTF scenarios that will let you break things you otherwise couldn’t, while keeping it as easy and safe to carry as possible.

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.

Gear Review: Work Sharp Blade Grinding Attachment

12 April, 2024

What should I be calling this review? It is actually a review of the optional add-on Blade Grinding Attachment for the Work Sharp Ken Onion Edition Sharpener, which is getting to be quite a mouthful! However although the Blade Grinding Attachment is an add-on accessory for the Ken Onion Edition Sharpener and can’t be used without it, I have titled the review as being a review of the “Work Sharp Blade Grinding Attachment” because for me it is what the attachment brings to the table that is the main feature.

I’ve had my eye on the Work Sharp Ken Onion edition for a long time. For me it wasn’t quite right (though I still think this is excellent as is) until I tried the optional Blade Grinding attachment.

For my needs it is the Blade Grinding Attachment that transforms the Ken Onion Edition Sharpener into a real workhorse sharpening system.

The Blade Grinding Attachment effectively adds a mini bench belt grinder to the Work Sharp, and this was the clincher for me. I’ve been using a 1″ belt grinder with an angle setting guide I made and added to it myself for 99% of my sharpening. Now, thanks to Work Sharp I’ve got a much more compact and specifically knife edge focused tool.

This fantastic sharpener is now being used to create the Tactical Reviews ‘WORK SHARP Sharp’ standard for all my knife testing.

Join me in this detailed look at the optional add-on Blade Grinding Attachment for the Work Sharp Ken Onion Edition Sharpener.

Before diving in to the image galleries, in effect there are two reviews combined here. The Work Sharp Ken Onion Edition Sharpener, and the separate Blade Grinding Attachment for this sharpener. This combination is also sold as a kit version called the Work Sharp Elite Knife Sharpening Solution.

A few more details:

What’s in the box? – Ken Onion Edition Sharpener:
This is the foundation sharpener, which is complete in itself.

A good look round the Ken Onion Edition Sharpener – Things to look out for here are:
Using an in-line transformer makes for a very tidy setup, and of course it will have the mains plug suitable for your country. Though it looks like a single machine, the sharpener is a motor/control unit, and a belt sharpening head that fits onto the motor assembly (this is important later when it comes to the blade grinding attachment).
The Ken Onion Edition Sharpener head has a pair of angle guides plus an edge guide to support the blade. To control the speed of the belt, the motor unit has a trigger with rotating maximum speed dial. The trigger also has a locking button so you can set it running and not need to hold the trigger switch, leaving you both hands free.
Sharpening angle is set using a dial adjuster with clearly marked angles from 15 to 30 degrees. The last image in the gallery with the spring showing is the belt tensioning roller.

What’s in the box? – Blade Grinding Attachment:
As well as the main sharpener, the Blade Grinding Attachment also has an unsupported, or ‘slack’ belt, so will create a convex edge. In the box are the attachment and a set of belts for it, as these are a different size/length compared to the main sharpener’s belts.

A good look round the Blade Grinding Attachment – Things to look out for here are:
One of the belt rollers is the motor spindle itself, so on its own it might appear that one belt roller is missing (but isn’t). The Blade Grinding Attachment has three rollers; one tensioning roller, and an angle adjustable set of twin rollers that give you the edge angle you want. A shelf at the front of the Blade Grinding Attachment gives you the zeroing position of the blade angle relative to the adjustable angle section of the belt. The set of twin rollers is moved to the desired angle and the locking screw on the back tightened to maintain this setting. There are two positions for one of the twin rollers that allow you to effectively change how ‘slack’ the belt is. The knob on the tensioner provides tracking adjustments for the different belts. There is even a small support shelf at the rear of the Blade Grinding Attachment for using as a mini belt grinder. Fitting to the motor is via a bayonet style of locking ring.

What it is like to use?
In this gallery, the first thing I am doing is taking off and discarding the sharpening head for the Ken Onion Edition Sharpener to leave just the motor assembly (no offense to the Ken Onion Edition). Then on goes the Blade Grinding Attachment. Now you can see how the motor spindle (which has a left-hand screw belt retainer fitted into it) then completes the belt roller path.
The tensioning roller has a finger tab for you to push on and it rotates and locks into a retracted position. Like this the belt pops on and off easily, and with the new belt in place, a quarter turn on the finger tab and the tensioner unlocks and grabs the belt.

Although the Blade Grinding Attachment has clamping points, I’ve been using the sharpener sitting under its own weight, and it hasn’t moved or needed to be secured.

The process of using the angled section of the belt, is to first lay the blade on the reference surface at zero degrees, then move up and to the belt. This sequence is showing the process on one side, then the other, and then going to a finer belt and repeating. The last photos in the gallery has an orange item on the right, which is an LED light used to help show the burr that has been raised on the edge.
In this gallery the two rollers that set the angle for the belt are shown in their widest spacing, however, since these images were taken I have changed to the narrower spacing as I prefer the slightly firmer belt tension this creates between the rollers.

Powered sharpeners give you such a massive time saving over manual sharpeners, but it is also possible to make mistakes faster too.

Here I have take on an edge bevel re-profile from a 70 degree inclusive angle to 35 degrees inclusive. The primary grind angle on this blade is quite wide, so as the edge bevel angle was halved, the edge bevel width has increased significantly. In fact the entire edge bezel does not fit in the magnified view.
This re-profiled edge was done using a very light pressure onto the 120 grit belt, followed by a strop using a metal polishing compound. The result was nicely hair popping.

Both the Work Sharp Ken Onion standard sharpening head and the Blade Grinding Attachment use a ‘unsupported belt’. There is no platen behind the section of belt used for sharpening. This is also termed a ‘slack belt’. A consequence of this is that the edge created by the Work Sharp is convexed. You can vary how much the edge is convexed in a couple of ways. With the Blade Grinding Attachment, the rollers that set the angle of the belt can be positioned closer (less convexed edge) or wider apart (more convexed edge). As the belt is ‘slack’ you can also increase pressure onto the belt, which will deflect it more and produce an edge with more pronounced convexing.
All of this allows you to play around with settings and pressure to find the edge bevel shape you prefer; always slightly convexed, but you can decide how much.

I am now going to back to that point about time saving with a powered sharpener; you will either save a lot of time making a knife very sharp, or ruin it in double quick time. No sharpening system is fool-proof. Sharpening, as a process, relies on removing metal and forming a fine cutting edge. Just like sharpening a pencil, you can over sharpen and use the pencil up much faster than needed. A powered pencil sharpener can eat up the entire pencil in no time.

Sharpening is a skill you need to learn, whatever system you use. Work Sharp, with the Ken Onion Edition, or this extra enhancement of the Blade Grinding Attachment give you an excellent tool, which you will get more and more out of as you learn to work with it.

With a good powered system, and the Work Sharp is excellent, you can concentrate on the skill and control of positioning the blade, without the repeated effort of grinding the metal away yourself. The powered movement of the abrasive allows you to finesse your technique.

Tactical Reviews new standard in sharpness is now ‘WORK SHARP Sharp’ thanks to the Ken Onion Edition Sharpener with Blade Grinding Attachment.

Knife Review: Extrema Ratio FRAME ROCK XXV Anniversarium

31 March, 2024

Extrema Ratio have been celebrating their 25th Anniversary in style with a number of limited runs of new and old models.

In this review we are looking at the XXV Anniversarium Limited Edition of the overbuilt folder, the FRAME ROCK. If you do miss out on the limited edition, most of the content here is perfectly valid for the standard FRAME ROCK, so limited or standard, you can get one of these ROCK solid folders.

This review of the Extrema Ratio FRAME ROCK includes an in depth video with overview and detailed measurements, plus image galleries and more.

Review Videos

Starting with a short format sixty second review:

Onto a full video review covering many more details:

What’s in the box?:
Included with the Anniversarium Limited Edition, is a special numbered presentation case and Anniversarium challenge coin. In this section, instead of unboxing we are looking at that special presentation case.

The Anniversary Coin:
Before we move on, here are both sides of the Anniversarium challenge coin.

A REALLY good look round the FRAME ROCK – Things to look out for here are:
Unprecedented in size, this gallery contains more photos of details than ever before, to take in as much of this special edition as possible.
Folded or not, the FRAME ROCK is unmistakably Extrema Ratio with its grip pattern. The FRAME ROCK has presence even though it is relatively compact. On the plain head of the pivot bolt there is an engraving of the anniversary logo with a further XXV Anniversarium engraving just above this. Immediately you can see the 6mm thick blade stock with heavy jimping. An integral lock, the FRAME ROCK has a steel insert on the end of the lock bar to increase lock life and it can be replaced if needed.
Extrema Ratio folders use a pivot bolt with locking screw that prevents loosening. Unusually, the deep carry clip wraps completely over the end of the handle, fixed onto the opposite side’s handle. As it wraps over it has a slot to allow the glass breaker to protrude through the clip (this can be fitted on the opposite side).
Waisted spacers hold the handles in place, and give the FRAME ROCK its open back layout.
As the glass breaker is fixed in the solid handle (not the lock bar side), to accommodate this, should you swap the clip side, there is an extra slot in the clip.
Looking right into the pivot, what is visible are the ball bearing cups for the pivot bearings that give the blade a smooth action.

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 N690 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?

A compact, heavyweight, overbuilt knife, it almost seems a contradiction, but the compact size actually allows for a relatively light weight for such a robust knife.
Featuring a beautiful spearpoint blade with fuller, using the same blade shape as the Contact and Contact C fixed blade models. The blade shape adds to the unique look the FRAME ROCK brings.
The more you handle it, the more you understand the allure of the unusual robustness for a knife of this size. Typically, overbuilt folders are much larger, but the FRAME ROCK fits within the hand, while having an incredible solidity – hugely satisfying.
Somehow it also belies belief that such a wide spearpoint could fit into the handle, looking all the more impressive as you swing it open.

For larger hands, the compact handle does mean the clip tends to dig in if you are working the FRAME ROCK hard, and in the left hand, the glass breaker can dig into your hand when taking a tight grip. But trade this off against the overbuilt strength you are carrying, a blade that will take on heavy tasks and not break a sweat.

Gear Review: Nitecore EMR05 EMR06

25 March, 2024

This detailed review of the Nitecore EMR05 and EMR06 portable mosquito repellers, includes all aspects of their performance and function.

The EMR05 and EMR06 are two new devices from Nitecore giving you ultra-portable insect repellers with the lowest weight-cost possible.

The EMR06 has a built-in battery, so is self-powered, and the EMR05 is smaller still, as it needs external power from a power bank.

If, like me, you protect everyone else from mosquito bites, by being the one the mosquitoes make a beeline for, then you may be as pleased as I am to find the new Nitecore EMR05 and EMR06 portable insect repeller devices.

Making his second appearance below is “Stoppo”, Tactical Reviews’ “don’t do that” guardian. Mosquitos beware, armed with the EMR units Stoppo says NO!

With the EMR05 and EMR06 bringing you ultra-portable versions of insect repellers, you can see just how much smaller they are compared to the EMR10 and EMR20.

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?:
Both the EMR05 and EMR06 are covered here. Each has a USB-C cable, wrist lanyard, and some repellent mats.

A good look round the EMR05 – Things to look out for here are:
The EMR05 is keeping things to the bare minimum. A power switch with indicator light, the slot for the repellent mat, USB-C port for power and a mounting system. Nitecore’s MOLLE mount system is really neat and effective.

A good look round the EMR06 – Things to look out for here are:
The EMR06 introduces a built-in battery while otherwise similarly keeping things to the bare minimum. A power switch, indicator light, the slot for the repellent mat, USB-C port for charging and a mounting system. Nitecore’s MOLLE mount system is the same here, so you can see the increased size of the EMR06, yet it is still very compact.

Technical Testing:
Both EMR units were setup with a modified repellent mat that held a thermocouple probe under it and positioned over the heating plate. This logged the temperature during the run.

Some notes on the graphs:
The EMR06 was logged first, then the EMR05. About halfway through the EMR06 measurement, my thermocouple data logger started to include a lot of noise from the optical USB PC link. When no logging was taking place the readings were consistent, but as soon as the logging was turned on the readings showed noise. So the second half of the EMR06 trace has noise, but if you ignore the noise on the trace you can see the underlying trend of temperature variation during the run. The behaviour of the EMR06 did change throughout the run.
For the EMR05, the noise is present for the entire run, but you can still clearly see a different temperature control profile to the EMR06.
Remember that the EMR05’s runtime depends on the input power source, so here is just stopped as there was enough run to see its behaviour.

In the second graph the view is zoomed in for the first 30 minutes of the run to show the temperature control profile of each unit better.

Also included in the section are the measurements of the operating current for the EMR05, and the charging current for the EMR06. The EMR05 is shown during the temperature logging measurements while drawing power from a Nitecore power bank, and with the thermocouple in place.

What it is like to use?

Compared to the previously reviewed EMR10 and EMR20, these two units are so small and light, why wouldn’t you carry them? Clipped to your bag, you don’t even notice you are carrying them.

Nitecore make and supply double size repellent mats. This is clearly the easiest way to load up the EMR05 and EMR06. It is possible to use two standard size mats instead giving you more flexibility.

The EMR05 needs a power bank to run from. It is highly likely you would be carrying you power bank of choice anyway, for charging various items, so with the EMR05, you can just run this from any power bank you happen to have, or a plug-in charger if you are in a hotel. I’m carrying the Nitecore SCL10 power bank as it is (amazingly) also a superb video light.

I’ve been using both the EMR05 and EMR06 in a variety of indoor and outdoor locations carried separately or clipped onto a bag.

So how did they do?

Firstly, with me being apparently the finest of dining for mosquitos, if they are determined enough, you will still get bitten; I did. I’ve been bitten when covered in deet, so using repellent mats outdoors might deter some, but is not absolute protection.

It is not at all possible to properly measure the effectiveness of these repellers as the number of bites will also depend on the time, temperature, and hatching of the insects, so this can be impressions only.

Assuming the mats themselves are effective, I have been aware of the aroma coming from the mats. Considering this is outdoors, that is reassuring. Effectiveness is so subject to wind direction and strength, so you might not actually have any cover of the repellent and insects might reach you undeterred.

NOTES on the repellent mats:

There are a few different active ingredients used in repellent mats, and these are also frequently in combination with Piperonyl butoxide. Prallethrin, Transfluthrin and D-Allethrin are the most common with Nitecore’s MRM10 Mosquito Repellent Mats using Prallethrin.

Piperonyl butoxide (PBO) is a man-made pesticide synergist. By itself, PBO is not designed to harm insects. Instead, it works with bug killers to increase their effectiveness. PBO is often combined with natural pyrethrins or man-made pyrethroids. It has been used in pesticide products since the 1950s, when it was first registered in the United States.

A repellent mat needs to be changed when it turns white. You can use Repellent Mats for a shorter period of time than the manufacture specifies and they will still be just as effective. However, if there is going to be several days between usages, you might want to keep the mats in their foil packaging or in a sealed plastic bag between uses.

Just like I wanted with the larger EMR10 and EMR20, the one feature I wish they both had was an auto-off timer. Once you turn on either one of them, they will run until the battery (or power bank) is flat or you turn it off. I found that treating at critical times was more important than all night and I would have preferred to be able to fall sleep with the repeller turning itself off after an hour or two and leaving power to run on another night.

While using the EMR05 and EMR06 I have been bitten. I am convinced I would have been bitten more without them. The most difficult aspect of their use is the protection zone they can provide. If you are walking, then the repellent vapour is trailing after you and not surrounding you. If there is wind, the repellent is blown away. In instances where you are not moving and there is wind, you need to put the device a few meters away from you and up-wind.

Some of the better results are for smaller or enclosed areas. Treating a tent, or a hammock net are idea uses. While on holiday, using it in a hotel or guest room works 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 that covered in the review.

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.

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

Knife Review: ANV M311 COMPACT

17 March, 2024

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.

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?:
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.

Gear Review: Wiley X Ozone

18 February, 2024

The Ozone is a new model which introduces yet another innovation from Wiley X, the Click Air Gasket.

In this review, the version of the Ozone on test also features the Wiley X CAPTIVATE lens which I previously covered as a separate in-depth review – Wiley X Captivate Lenses (Models shown – Contend, Peak and Breach).

As someone who relies daily on the best quality sunglasses, but that also needs EN. 166 & ANSI Z87.1 safety standards, Wiley X has been my go-to brand and has never let me down.

Since first finding Wiley X many years ago, I’ve not looked back when it comes to eye protection, lens quality, fit and style.

Review Videos

Starting with a short format sixty second review:

Onto a full video review covering many more details:

What’s in the box?:
As a model that uses the facial cavity seal (in this case the click air gasket), as well as the normal neck strap, it also includes a headband retaining strap, so the Ozone can be worn just like goggles
There is a zip up storage case, and a dual-purpose cloth bag that can also be used to protect the glasses and as a cleaning cloth.

A good look round the Ozone – Things to look out for here are:
Being absolutely fresh out of the box, here you can see the retail tag with the model details still on the arm. Scrolling through the gallery you are taken round the Ozone to get a feel for the characteristics of this model including details like the hinges and logo on the arms.

Click Air Gasket Details:
Now to focus onto the click air gasket itself; the gallery starts with an overall view of the foam border of the facial cavity seal. Then we move onto a series of photos with the click air ventilation open and closed (including looking from inside). Lastly showing the gasket removed.

Goggle style head strap:
A brief section to look at the goggle style head strap and how this fits to the end of the Ozone’s arms.

The Click Air Gasket removed:
You might not want to use the Ozone with the facial cavity seal all the time. This excellent feature can, in some cases, lead to steaming up of the lenses, even with increased ventilation, so you can just pop the click air gasket out and use the Ozone as the bare frame.
This also gives us an opportunity to look over the gasket separately.

Measuring Light Transmission:
Wiley X are great at providing all the specifications for all their different lens variations. I wanted to just take my own measurement to compare.

Using a lux meter, and taking a control measurement, then a measurement with the lens in place over the light sensor, you can see here that the Blue Mirror Polarised CAPTIVATE lens has a 10.62% transmission (for the frequencies this light source / lux meter respond to).

This lens version is one of the lowest transmissions and perfect for my requirements.

What it is like to use?

Readers who follow me might remember I have a condition making me hyper-sensitivity to light, and that this means I wear sunglasses every day at all times that I am outside during daylight hours (and frequently indoors as well). So when I say I have lived with these sunglasses from Wiley X, I have lived with them and worn them for hours and hours every day for months.

In most cases I prefer polarized lenses for glare reduction and enhancing colour depth and am very familiar already with this CAPTIVATE lens.

If you have not yet tried a Wiley X model with facial cavity seal, I thoroughly recommend you do, they are something quite different, providing you with a close fit and unmatched level of protection and coverage. You really feel protected in the way you would normally need to be using goggles to achieve. They are not a complete seal, so are not appropriate if you need complete protection from dust, but instead give you much better protection from wind and grit than normal sunglasses can provide.

‘Active wear’ is a good term for the models with facial cavity seals, as they often need you to be active and moving for the ventilation to keep the lenses from steaming up, especially if you are hot, or if the air is very cold.

Knowing the reality of near-goggle like eyewear, the Click Air system then improves the situation. With a simple click of the gasket above your nose, you open up an extra vent to allow more air flow and ventilation. Then just as easily, once the extra ventilation is no longer wanted, another click to close off the extra vent.

The position of the Click mechanism means it sits against your face, so it is not possible to operate this while wearing the Ozone and also wearing gloves. If you are wearing gloves, you’ll need to quickly take the Ozone off, to open or close the vent. If you have bare hands, you can carefully squeeze the Click mechanism while wearing the glasses. So depending on what you are doing this may or may not be practical to open/close on the move.

Taking the gasket off completely, initially makes the Ozone feel a whole size larger, and takes a bit of getting used to after feeling the warmth and protective effect of the facial cavity seal. I do go between using the gasket and not depending on the activity, and/or my temperature and the outside temperature. Also, for the thorough cleaning I give them, the gasket always comes off to give full access to the lenses and frame. I also wash the foam seal gently with a gentle ecological washing up liquid to keep this clean.

Until you get used to it, there is another feeling you might get with the facial cavity seal. Due to the seal being in direct contact with your face and round your eyes, it can feel as if the seal itself is pushing the glasses slightly off your face. The head strap provided will completely resolve this and give you a sense of security that nothing is going to shake them loose. Similarly, the standard neck lanyard strap with its sliding toggle can give you a very similar result.

With many different ways to wear the Ozone you, are getting a brilliantly flexible pair of sunglasses that will protect you from much more than sunlight.

Remember Wiley X offer a wide range of sizing options with the specifications clearly shown so you can find the right fit for you – another reason I find Wiley X difficult to beat.

Knife Review: Sandrin Knives Torino

17 February, 2024

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.
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.

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.
