Knife Review: MKM Jaques Slipjoint

In this detailed review of the MKM (Maniago Knife Makers) Jaques – a modern slip joint Folding Knife – find out if it could be your ideal EDC companion.

The MKM Jaques is a slip joint folding knife designed by Jesper Voxnaes. The Jaques has a satin finish CPM MagnaCut Wharncliffe blade, and the version in this review features Fat Carbon DARK MATTER BLACK handles.

“The Jaques design is my modern take on the folders I have seen used by European winegrowers in both Italy and France but mixed with details from some of my favourite American slip joint patterns. A nice sized utility folder, in high-end materials, with great feel in hand. A perfect for EDC for urban and outdoor settings.” Jesper

Read on in this MKM Jaques Review for all the details.

What’s in the box?:
For this section there is no box or packaging to include, as this specific knife was a ‘show knife’ at IWA Outdoor Classics 2025 (and possibly other exhibitions). It also means that in the following galleries, any imperfections will be due to the knife being handled by a lot of people during the trade fair.


A good look round the folded MKM Jaques – Things to look out for here are:
With this version, the DARK MATTER BLACK handles compliment the bronze titanium bolsters/liners perfectly. Each and every knife with this handle material is unique, and the handle scales are secured to the combined bolster and liner with three screws. A single position stainless steel wire pocket clip, can be removed if you prefer not to use it. Only one side of the pivot bolt has a torx screw head, with the other being blank. The back-spring spacer is beautifully polished giving the Jaques a very refined look. The pivot specification states ball bearings. No bearings can be seen when looking into the knife, so these covered bearings should be more dust resistant than when you can see the ball bearings themselves.


A good look round the open MKM Jaques – Things to look out for here are:
Snapping the Jaque’s blade initially out to the half-stop position, we get a good view of the wide Wharncliffe blade. With the blade open we can more clearly see the handle shaping with two finger grooves; first finger and third finger. It’s a powerful full-flat grind Wharncliffe blade with elegant swedge sweeping down to the point, which also has an inconspicuously incorporated nail nick. MKM’s logo sits above the engraving of the steel type; Magnacut. Though not strictly a sharpening choil, the heel of the cutting edge does stand proud of the tang, and just forward of the plunge line; this allows the entire cutting edge to be sharpened. On the opposite side of the blade, the designer’s (Jesper Voxnaes) logo is engraved and onto more views of the blade.
Thumb grip jimping has been included across the ‘H’, and you can also see the small clearance step cut around the pivot to ensure the blade rotates without contacting the liner. Looking inside the handle you can see the stop pin for the blade tang to rest on when folded.


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 Magnacut steel.

With the Jaques being a slip-joint folder, the resistance to closing (and related stiffness of opening) is an important factor, so for this I carry out Torque measurements for opening and closing. The detailed video for this knife includes a section explaining this in more detail.

And the torque measurements for the Jaques (for further reference values check the Technical Testing link):


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?

The MKM Jaques immediately strikes you as both traditional and cutting edge design (pun intended), with a fusion of classic lines and styles with the very latest materials in a really easy to carry tool. Remember that ease of carry is what makes a tool the best one you have, as the fact you have it on you means it is the best tool for the job.
However, it is not only easy of carry, but that you choose to carry it, that is the final determining factor for being the best tool. For me, a Wharncliffe blade has always been one of the most practical choices, with the blade tip presented for immediate use, and the straight cutting edge easy to control, plus it is also easy to maintain the straight edge.
I take an XL size glove, and some pocket knives can feel too small in the hand; the Jaques does not. Compact, yes, but a very useful size. With the first and third finger grip grooves, it is very stable in your hand. Bearing in mind this is a slip-joint, so you are not going to be working it very hard, there is plenty of grip and plenty of blade.


I would prefer a slightly deeper carry clip so that only the clip is visible in your pocket and none of the handle, but the clip, as it is, is very neat. That would just be a slight change I would make if I could.

The action is nicely crisp, with a good resistance to closing (as proven by the torque measurements). In a slip-joint, I remain unconvinced about the benefits of using ball bearings; this is a personal view relating to the fact there is significant slip-joint back-spring pressure, and considering that over the full lifetime of the knife solid washers would removing the possibility of dirt/grit affecting ball bearings. However, it is very smooth in action, even with the spring resistance making that action very firm, so whatever my personal preferences may be, the blade action is very slick and pleasing.

Looking back at this gallery, I realise that all the jobs I have been using the Jaques for have been those smaller, make a cut – fold and stow, type of jobs and I wasn’t getting a camera out to capture it. Round the garden, at the post office, DIY, at work, all those jobs you use the knife you have on you to do. All done with ease and comfort, while appreciating the fit, finish, action and really effective blade. I’ve only once substituted the Jaques for one job where I preferred to use a disposable utility knife for – no point in knowingly damaging a quality knife for the sake of it.

As I write I also realise the edge has not needed any touch up, even considering this was the original edge that has been to big exhibitions and been used, dropped, handled so many times, yet it is still going strong.

Sadly these days, a knife’s looks are also important for the wrong reasons. What I mean by this is that some knives look ‘dangerous’ (in the words of others), but the Jaques has a gentle, traditional, look and feel which has been well received universally. In fact, it has been often complimented by people that might otherwise be critical of a knife. This allows you to feel more relaxed using the knife when others might see. A rare thing to really be able to enjoy using a knife wherever you are (at least in the UK).

Knife Review: MKM Hero

Join me in this review of the MKM Hero as we take in all the details of this superb new folding knife designed by Tommaso Rumici. Working with MKM (Maniago Knife Makers) Tommaso has focused on usability and versatility in a design that specifically delivers the ambidextrous features a real working knife needs.

Video Overview

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


What’s in the box?:
The Hero arrives in what initially looks like a simple storage pouch, however, on the back are a couple of belt loops, meaning the pouch is actually a horizontal belt pouch as well. Within the pouch is a pocket that has a double-ended T6/T8 torx wrench and leaflet.


A good look round the Hero – Things to look out for here are:
The version of the Hero in this review has the marbled carbon fibre handle. The liners and integrated bolsters are milled from one-piece of titanium with the handle slabs set into them. Cut into the reversible titanium clip is MKM’s distinctive mountainscape logo. The clip is held in place by two torx screws, making it easy to reverse the clip.
Double-sided stepped thumb studs allow ambidextrous blade opening. Choice of the back-lock is another intentional ambidextrous design feature. Jimping for extra thumb grip spans the blade and lock bar.


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.


What is it like to use?
I had the good fortune to be introduced to the Hero by its designer Tommaso Rumici, and get a run down of the features directly from the horse’s mouth. To my amusement, with this demonstration coming near the end of IWA 2022, and hands being well sanitised, and dried to a crisp, I managed to crack my thumb open on the Hero’s thumb stud and bleed all over the blade without actually cutting myself on the edge.
As I have got to know the Hero, there is one aspect I’m not so keen about, and that is that the thumb stud is a little on the pointy side. You do need to be careful to press onto the side of the stud and avoid pushing straight onto it to swing out the blade.
A good back-lock makes for a supremely practical layout in an ambidextrous focused knife. Unlike liner or integral locks, which are handed, the back-lock is predictable, reliable and absolutely identical in operation regardless of the hand holding the knife.
Where a lot of the design intent shows through is in its handling, and we must talk about the Hero’s handle. In terms of width, the Hero is actually pretty slim, so is nicely low profile in a pocket, but the depth and generous swell/hook at the butt of the handle is where the huge flexibility of grip positions and fantastic grip stability comes from.
For really controlled work, you can choke right up on the handle and place a finger on the guard/bolster bringing you to the cutting edge. At the complete opposite extreme grip position, taking a hold when you might want to use a chopping motion, thanks to the grip swell, you can take a secure grip of the very end of the handle with your first two fingers without worry of losing your hold on the Hero even when striking down with it.
Then you can take the middle ground with a standard grip and rest your thumb on the jimping that spans the end of the lock bar and blade for control and cutting force. When using this grip position, you can alter the angle the blade is presented by changing the pressure of your little finger on the butt hook. Doing this makes the knife swivel about your first finger, opening out, or closing in the position of the blade relative to your hand and making the blade extremely agile in use.
Exactly as intended, the Hero is big enough for most EDC tasks, and most general purpose jobs, yet not too big to put you off carrying it.

Knife Review: Heinnie Special Editions – CRKT Pilar, MKM Isonzo and Penfold

In the UK, Heinnie Haynes is an institution and essential in the search for knives as well as outdoor and EDC gear. Having been a specialist in knives for so long, not satisfied with just selling standard production knives, Heinnie Haynes have been commissioning customised and enhanced special editions, many of which are slip-joint conversions of lock knives (to allow UK EDC). In this review we are taking a look at three of these Heinnie special editions – a slip-joint conversion of the CRKT Pilar and MKM Isonzo, plus a the sleek Heinnie designed Penfold.

The details:

This video has a quick look at the Heinnie Penfold and MKM Isonzo, and then a much more detailed examination of the CRKT Pilar.


A good look round the Heinnie CRKT Pilar – Things to look out for here are:
The exclusive special edition features include the G10 scales and spacer in Heinnie red, plus the conversion to slip-joint using a double spring-and-detent concealed within the handle.


A good look round the Heinnie MKM Isonzo (Cleaver blade)- Things to look out for here are:
Originally using a liner lock, the remains of this lock are clearly visible, but with the addition of a detent on the sprung bar (previously the lock bar). Highlights of Heinnie red let you know this is the special edition.


A good look round the Heinnie Penfold – Things to look out for here are:
Entirely a Heinnie design, the Penfold takes the classic pocket-spring slip-joint knife, and streamlines it with a beautiful simplicity and clean look.


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 Torque measurement:



What is it like to use?

As a little ‘cherry on top’ I’ve added a couple of Heinnie beads onto paracord lanyards.


This led me to make a how-to video for the lanyards I like to tie. See Tutorial Page Here.


Inspired by the rasp-like grip texture of the MKM Isonzo handles (plus noticing other ‘pocket ripping knives’ over the years), a new test was born – the pocket-shredder test. Taking some raw calico and fitting and removing the knife’s pocket clip onto the calico fabric as if it were a pocket edge. This was done only 5 times; here you can see the comparison of how aggressive the pocket clip grip is. The MKM is a shredder!


Heinnie Edition CRKT Pilar – It’s a compact knife, three-finger-grip size, so, frustrating for it to be a lock knife where carry restrictions prevent EDCing a locker. Heinnie Haynes special slip-joint edition makes this a lovely, and EDCable, working knife. It is a slight disappointment that it only has a tip-down pocket clip. I initially thought this might be a deal breaker and this does conflict slightly with the lanyard hole, as to use the pocket clips means stuffing the lanyard into your pocket, opposite to how it should be. However, thanks to its small size and ease of handling it actually hasn’t been a real issue.
The sheepsfoot blade shape is very practical, presenting the tip and edge nicely for draw cuts.
One-handed-opening is easy and the slip-joint detent is firm enough (assuming correct cutting technique). Thanks to the vision of Heinnie Haynes, we have a super usable, easy to carry, and inexpensive EDC pocket knife.

Heinnie Edition MKM Isonzo Cleaver – This knife drew me in as soon as I saw it, Jesper Voxnæs’ distinctive design, which was also originally a liner-lock knife. With Heinnie Haynes stepping in and arranging for a slip-joint conversion to open up this excellent knife’s EDC-ability.
In this version, it has the ‘cleaver’ blade (although effectively this is really a slightly deeper sheepsfoot shape), with the characteristic downward presentation of the tip, making it a very practical cutter.
The peeled G10 scales have a texture that almost reminds me of the rasp side of a box grater (the one you end up skinning your finger joints on). This texture is super grippy, and I feel I could keep hold of this despite oil or anything else slippery on my hands.
For its overall size, the Isonzo is quite wide when folded; wide enough I could not fit it into any of the knife belt pouches I have. The secure grip from the rough handle texture is actually really good, and feels fine for general use, so I definitely want to carry this. Despite being my preferred tip-up clip position, its ferocious grip texture makes the pocket clip something I won’t use, as it will rip pockets to shreds; so, I just popped it into the bottom of whatever pocket or pouch/bag I had.
With a deep full flat grind, the blade had the narrowest primary bevel angle of the three in this review, and proved a great slicer with lots of control.

Heinnie Penfold – Those sleek lines make the Penfold beautiful in its simplicity. This is a knife imbued with elegance and sophistication, and a joy to behold every time you bring it out. When this arrived, I got out an old leather belt pouch I’ve had for probably over 25 years, and it’s been on my belt every day since then (with the Penfold in it of course).
Initially I was a little put off by the thickness of the blade. In terms of visual design, the thick blade looks super, but a thick blade loses out in slicing ability, so I didn’t have high hopes for the usability. Well, I could not have been more wrong; every task I’ve used it for has been completed with ease and not impeded by the blade thickness. There will be some cutting jobs the blade thickness may end up slowing down, but so far this has proven a cracking daily carry!
