Sharpest Knife Competition at IWA 2019

This year at IWA, Tactical Reviews is throwing down the gauntlet and asking the knife trade “How sharp can you go?”. OK, it’s actually a lot less formal than that, a ‘just for fun’ competition to see who can create the finest edge on a knife blade, by any means they choose.

Entry is free and open to all exhibitors and visitors to IWA 2019 (see rules below). There is no prize beyond the warm feeling the winner will have, knowing they had the ‘Sharpest Knife at IWA’.

Come and find me with the awesome people at Chris Reeve Knives in hall 5, stand 5-135, on Sunday 10th March between 16:00 and 17:00. Get in early or you might miss out.

How is the sharpness measured? Using a PT50A BESS Certified sharpness tester:

The BESS ‘C’ scale of sharpness, developed by Mike Brubacher (Brubacher Edge Sharpness Scale) will be used to determine how sharp each knife edge is. The ‘Edge on Up’ PT50A tester uses a certified test media fibre and records the force required to cut it. The lower the score the better. As an example, a typical Morakniv factory edge scores around 250. See this guide:


Every knife tested will be given an official sharpness score and certificate. A measurement will be taken initially in the centre of the blade, then the heel, then the tip, and an average value taken. This will test the sharpness over the entire blade, not just the easiest part to sharpen.

‘The Sharpest Knife’ Competition – IWA 2019

Rules:

  1. Open to all knives, custom-made or production. – No Razors allowed.
  2. Kitchen knives, though allowed, are NOT eligible to be overall winner; they have been found to have too much of an advantage, so may be entered for an honourable mention only.
  3. Any knife deemed not to be in the spirit of the ‘sharpest knife’ contest will be disallowed (surgical/laboratory etc.).
  4. Open to anyone – Professional / Maker / Amateur / User.
  5. Knives must be submitted either folded or sheathed, with the cutting edge covered.
  6. Each knife will initially have a single measurement taken. If the result is within 50 BESS of the leading entry, further measurements may be taken (at the discretion of the tester).
  7. Subject to the previous rule, each qualifying knife will then have a set of three measurements taken along the blade (centre, heel and tip) with the average BESS score counting as the result.
  8. In the case of a draw, the lowest individual score will be used for secondary ranking. If there is still a draw, the first one tested will win.
  9. The tester’s results are final – No knife may be entered twice.

The winner will be announced at close of the competition.

Knife Review: Chris Reeve Knives Nyala (Insingo blade)

Chris Reeve Knives’ Nyala fixed blade knife (first released in 2010) is a classic skinner / utility knife. Available in a drop-point, or, as featured here, the Insingo style blade (a modified Wharncliffe), and coming in a traditional leather pouch-sheath. Despite being a modern contemporary design, it achieves a timeless feel and benefits from the best manufacturing and materials you could ask for.

A few more details:

Starting with the sheath:

A good sheath is as important as the knife it carries, and CRK have gone to leatherwork specialists Gfeller for the Nyala’s pouch sheath.


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

Simple, elegant and purposeful, the Nyala in detail. Look for the attention to detail in the design and refinement of every part of the knife.


The Blade and Handle – Detailed Measurements:

Now even more detailed!

Taking things far beyond most knife specifications, in this section I will be carrying out a detailed examination of geometry, balance, edge bevels, factory sharpness and structural edge testing using the industry leading measuring tools.

These measuring tools include a Vernier protractor, callipers, fixed radius gauges, the unique Arc Master adjustable radius gauge, Edge On Up’s BESS Certified PT50A and SET tester along with CATRA’s Hobbigoni LASER Edge Protractor.
The BESS ‘C’ scale of sharpness (Brubacher Edge Sharpness Scale) will be used to verify the sharpness of the factory edge and allow the knife to be brought to a minimum standard sharpness before testing a blade’s cutting performance.


The measurements have been tabulated and are presented along with a few reference blades. The ‘Balance relative to the front of the handle’ tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The ‘Balance relative to the centre of the handle’ indicates how close to a ‘neutral balance’ the knife has in the hand.


The blade is made from CPM S35VN steel.

What it is like to use?

Being a fan of Chris Reeve Knives’ folding knives, I also ‘needed’ a Pacific fixed blade, but in all honesty had never really hankered after the Nyala. Something I’ll come back to is the handle sizing, which has always appeared a bit on the small side to my eyes and was another reason I had not pursued it. It is also a slightly understated knife design, but that happens to be part of its charm. As you would expect from CRK, there is an elegance and minimalism in the design which keeps things simple and effective, and does so without shouting about it – quiet and efficient.

Given the opportunity to try this knife out, I had the choice of the drop-point, or CRK’s Insingo blade style. The modified Wharncliffe works for me, as I do a lot of point work and like the way the entire edge presents itself forward for the type of cuts I make, so the insingo it was.

Following on from the earlier look at the sheath, I wanted to start this gallery with one of those details that just make all the difference. See how the jimping in the centre of the grip is positioned such that a couple of grooves are visible when sheathed. This gives your first finger a better grip to withdraw the knife from the sheath; a small detail but one that counts.

You can get a good idea of the sizing looking at the Nyala ‘in-hand’, a comfortable general purpose blade with the balance point in your hand. Without thinking, you find your thumb on the jimping provided for it; the width of the spine, and gentle rounding of it, provides a comfortable surface to press on.


So my concern over the size of the grip? Firstly, I’ll say that very much like a kitchen knife, the integral guard formed by the narrowing of the grip next to the blade makes it safe and secure. This narrowed grip also makes the Nyala nimble in the hand and great for fine, controlled, cuts. When assessing a knife handle I tend to think of the heavy cutting and how comfortable it will be when really pressing into the cuts. Actually the Nyala has surprised me, being comfortable enough with high effort cutting, even if not one I’d choose for extended periods of hard work. There is never any lack of grip from the milled micarta handles, the depth of the milled grooves can start to burn a bit after heavy use with bare hands. The balance of quality of grip vs comfort does seem just right for the shape / size of the handle.

The blade stock is a little thicker than I’d really want in this size of knife, but this allows for a comfortable thumb rest directly on the spine, and that extra strength is just lying in wait for a time you might really need it, which is never a bad thing.

Overall I’ve also been appreciating the simplicity and traditional vibes of the Nyala with its leather sheath. Now I’m wondering why I overlooked it for so long. It has been working as a really good all-rounder and has fallen into my regular rotation.

Knife Review: Chris Reeve Knives Large Inkosi

The original Inkosi was launched at Blade Show 2016, and was designed to include improvements to Chris Reeve’s already tried and tested (and industry changing) Sebenza models. Never one to stand still, Chris knew he could improve on his original design with certain key changes to the pivot, bearing, frame and lock. Rather than apply all these changes to the established formula of the Sebenza models, a new line was created to allow these features to be incorporated into the most advanced Chris Reeve folding knife yet. With a trend to smaller more pocketable models, the first Inkosi was created as a compact folding knife, but demand has been strong for a larger version of this knife, and here it is. The Large Inkosi now replaces the Sebenza 25.

The Blade and Handle Geometry:

Most knife specifications have a basic description of the blade geometry, but in this section I will be taking a more detailed look at geometry and balance.
 photo 56 L Inkosi grind measure P1200597.jpg

Using a set of gauges and precision measuring equipment including a Vernier protractor, callipers, fixed radius gauges and the unique Arc Master adjustable radius gauge (the one that looks like a crossbow).
 photo Knife measuring P1180483.jpg

These measurements have been tabulated and are presented along with a few reference blades (8″ Chef’s Knife, 5.5″ Santoku and the popular Fällkniven F1).

Key aspects such as the primary bevel angle, grind type, blade depth, blade thickness, length, weight are detailed, along with balance information.
 photo 58 L Inkosi grind angle P1200604.jpg

The ‘Balance relative to the front of the handle’ tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The ‘Balance relative to the centre of the handle’ indicates how close to a ‘neutral balance’ the knife has in the hand.
 photo 53 L Inkosi balance P1200569.jpg

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

The blade is made from S35VN steel at 59-60RC.

Explained by the Maker:

The reasons for certain design choices may not be clear when simply looking at an object, so this section is intended to give an insight into the thinking behind a design by speaking to the designer themselves.

Unfortunately I can’t always get time with the designer so will use this section to include relevant information about the knife and its designer.

The history of this review goes back to before the release of the Large Inkosi and to IWA 2016 where I was fortunate to be able to speak to Tim Reeve about the Inkosi. It was during this discussion that Tim told me the Large Inkosi was in development. My own preference is for a larger lock knife, so I couldn’t wait for the Large Inkosi to be released.

Tim talked me through the design improvements introduced with the Inkosi which actually include all the major parts, the pivot, bearing, frame and lock.

There is one feature of the Large Inkosi which is not new, but is worthy of mentioning as it is now a CRK design feature that was introduced in the Sebenza 25, the ‘Large Hollow Grind’. The shape of this grind is itself not new, having been common when you go back to older production methods. Before grinding wheels were mass produced in smaller sizes, blades were ground on much larger wheels than are generally used today. Modern grinders tend to have smaller diameter wheels, so hollow grinds have become deeper and more pronounced. This has given the hollow grind its very sharp thin edge, but a blade which hangs up on the shoulders of the hollow grind when cutting deeply. With the growing popularity of the full flat grind, thanks to its smooth cutting action, the modern hollow grind has been losing traction.

That said, both hollow and flat grinds have their place and individual benefits. When looking to make the folding knife as useful as possible, CRK didn’t just follow the trend of going one way or the other, but instead wanted a blade that blends the best of hollow and flat grinds. Using a much larger wheel to grind the blade results in a ‘Large Hollow Grind’ which is almost flat, but slightly hollowed. This stops the blade hanging like a hollow grind would, and allows for more sharpening cycles before the blade edge starts to thicken up. This image (borrowed from CRK) shows how the ‘Large Hollow Grind’ fits between flat and hollow grinds.

 photo largehollowgrindweb.jpg

Here you can see the slight dip of the grind with a flat edge lying across it.
 photo 54 L Inkosi grind P1200578.jpg

In the previous section ‘The Blade and Handle Geometry:’ you could see the size of the hollow grind being measured with the Arc Master radius gauge. This is a closer look at the measuring arc sitting in the hollow grind with the gauge set at 12″ radius, so a 24″ wheel has been used for this grind.
 photo 57 L Inkosi grind measure close P1200593.jpg

This next image is a big hit of detail as it shows the Large Inkosi almost fully disassembled. For the moment there are two specific details I’d like to focus on and they are the large pivot and shaped phosphor bronze washers.
In earlier designs, the size of the washer on the lock side was limited by the end of the lock bar and if the washer were to have a cut out, it might rotate and then interfere with the lock. In turn, the size of the washer limited the size of the blade pivot, as if the pivot were made larger, the washer would become smaller and provide less support to the blade.
Taking the washer to the maximum size allowed by the handles means it can then be shaped to locate on the blade stop pin and not rotate into the way of the lock bar. It also allows the washers to be the same both sides bringing equal stability to each side of the blade.
Now that the washer has broken free of the earlier limits, it is possible to increase the size of the blade pivot and so increase the strength of this joint.
However, all this extra contact area increases friction with the blade tang, making the knife more difficult to open, so large perforations have been added to the washers to reduce friction without weakening the support of the blade. The perforations also store more lubricant and offer space for small particles of dirt to move away from the contact surfaces of the blade and washer, helping to prevent blade from stiffening up over time.
 photo 14 InkosiWasher Step all parts plus new P1230240.jpg

Only with the knife fully disassembled can you get a really good look at another design feature, the ceramic ball used in the lock.
Other integral locks use either the titanium itself or an insert of hardened steel for the locking surface. Looking to improve on both if these and increase the service life, CRK have employed some of the hardest material available, ceramic.

A one-eighth inch ceramic ball with hardness of 97RC acts as the interface between the lock bar and the blade tang. It also doubles up as the detent ball that holds the blade in the closed position. Due to the detent now becoming the locking surface as well, you get a uniquely smooth feel when opening the Inkosi. For just about every other integral/liner lock, when the blade is nearing fully open, the detent ball clicks as it drops off the locking surface of the blade tang. Only after this pre-lock click does the actual lock click into place. It means you get this double click as the blade is opened into the locked position. With the Inkosi, when you start to use it, you’ll notice the absence of this pre-lock click as it is not what you are used to. You open the blade and the only click is the lock bar falling into place. This is only possible with the dual purpose ceramic ball.
 photo 32 Inkosi details lock ball P1230233.jpg

Unlike a standard lock interface, which uses two flat surfaces, we now have a round ceramic ball which would create a point-contact on the blade tang, so instead of having a flat locking surface on the blade tang, the Inkosi has a rounded groove with the same curvature as the ball.
 photo 23 L Inkosi washer lock groove P1200402.jpg

The ball and groove mate securely and this interface also stabilises the lock bar as it can’t flex away from the handle. (NOTE: since the review sample was provided, CRK have found the ball track groove on the tang to be unnecessary, so it is no longer included on current production Inkosi knives.)
 photo 33 L Inkosi ceramic ball P1200442.jpg

Another innovation in the Inkosi is the slip-through stop-pin in the frame. One end of the stop-pin is secured to one side of the frame with a bolt, but the other end simply fits through a hole in the front of the frame and is not fixed in place.
Of course this only works as well as it does due to the high precision of the fit of the stop-pin on the floating side, and this configuration provides an excellent advantage in the operation of the knife.
Traditionally the stop sleeve, which spaces the frame/handle parts, needed to be very precisely sized to ensure that the fit of the assembled knife was tight, but not too tight. If that stop sleeve is a touch too wide you get blade play.
With the slip-through stop-pin, the advantage is that the front face of the handle can move along it as you set your pivot tension. The Sebenza has a stop sleeve that has to be machined to a width accurate within a few tenths of a thousandth requiring a lot of fitting to ensure the knife operates as it should.
From a manufacturing perspective, this feature removes the need for the fitting of the stop sleeve, however, the main advantage is really for the owner of the knife, as the slip-through stop-pin guarantees that even once the knife wears in, the action can always be set perfectly, with no blade play and perfect washer contact, just by adjusting the pivot; the stop-pin will never need any adjustment because it is self adjusting.

A few more details:

Amazing how this box generates a real sense of anticipation and excitement. (NOTE: CRK have subsequently updated the packaging.)
 photo 01 L Inkosi box P1200318.jpg

Personally, I’m not sure a knife should come with a warning it is sharp, but there it is.

Nestled into a foam liner is the Large Inkosi and some accessories.
 photo 04 L Inkosi box tray P1200331.jpg

Along with the Large Inkosi you get a CRK cleaning cloth, two Allen keys for the pivot and one for the spacer and stop-pin bolts. there is also a tube of grease and thread-lock, giving you a full service kit.
 photo 05 L Inkosi box contents P1200337.jpg

Not to skip over this too soon, please note that these are not unbranded tools, you get WIHA Allen keys.
 photo 02 InkosiWasher tools P1230169.jpg

The grease is a fluorinated grease and thread-lock is Loctite 222.
 photo 06 L Inkosi tubes P1200340.jpg

There is something special about that box-fresh CRK knife.
 photo 07 L Inkosi cloth P1200349 copy.jpg

The Large Inkosi arrives with a knotted cord lanyard already fitted to the knife.
 photo 08 L Inkosi cloth2 P1200353.jpg

As with the Sebenza 25, the Inkosi has finger grooves in the handle.
 photo 09 L Inkosi angle P1200355.jpg

Fit, and finish is flawless, just as you would expect with CRK.

The understated logo sits next to the large pivot bolt.
 photo 13 L Inkosi pivot logo P1200368.jpg

Switching to the back of the frame and you can see the left-hander’s thumb stud, but there is less space between it and the lock bar than for the right-handed thumb stud.
 photo 14 L Inkosi lock side P1200369.jpg

On the back, the pivot bolt looks identical. You can also see the stop-pin bolt as the stop-pin is only fixed to the back of the frame.
 photo 15 L Inkosi Idaho made P1200373.jpg

Start casting your eyes towards that pocket clip.
 photo 16 L Inkosi full lock side P1200375.jpg

Another part of the CRK folder design that has changed is the movement of the clip so that it sits directly onto the frame instead of onto the lock bar. This ensures no additional pressure on the lack bar which might make opening the knife more difficult.
 photo 17 L Inkosi clip angle P1200376.jpg

Giving excellent grip, there is a section of asymmetrical pattern jimping on the thumb ramp.
 photo 19 L Inkosi jimping P1200384.jpg

A single bolt holds the clip in place and can easily be removed if you prefer not to have a clip.
 photo 20 L Inkosi clip fixing P1200387.jpg

To create the lock bar spring, two large radius scallops are cut out of the bar.
 photo 21 L Inkosi lock spring P1200391.jpg

Providing the spot of colour, the ambidextrous thumb stud is blue PVD finish.
 photo 25 L Inkosi stud spine P1200408.jpg

With the blade partway open, here you can see the ceramic ball is out of the detent hole and sitting on the side of the blade tang. Like this the lock bar now stands slightly proud of the frame.
 photo 26 L Inkosi lock bar out P1200415.jpg

When the lock engages, the lock bar has clearly moved into the frame. Also note here how the washer is actually larger than the blade tang.
 photo 27 L Inkosi lock bar engaged P1200419.jpg

The blade has a beautifully even stonewash finish.
 photo 28 L Inkosi angle open P1200420.jpg

Zooming in to the blade tip.
 photo 29 L Inkosi blade tip P1200422.jpg

With the blade now open, both sides of the finger grooves can be seen. The first finger groove is deeper on the front of the frame giving right-handers easier access to the thumb stud.
 photo 31 L Inkosi finger grooves P1200434.jpg

In the assembled knife you can see how the over-sized washers are fitted to the lock bar cutout in the frame.
 photo 32 L Inkosi washer cut P1200437.jpg

A nicely radiused plunge line takes you from the blade grind to the full thickness of the blade tang.
 photo 39 L Inkosi plunge line P1200467.jpg

Though it looks almost like a flat grind, the large hollow grind is noticeable as the light plays on the blade. (Of course it would help if this image was animated, but it is not.)
 photo 40 L Inkosi large hollow P1200473.jpg

There is a gentle curve to the blade spine which is very comfortable to press on. It does mean you won’t be striking sparks of a ferro-rod with it.
 photo 41 L Inkosi spine P1200476.jpg

A close-up look at the thumb stud.
 photo 44 L Inkosi thumb stud P1200499.jpg

On the first run of Large Inkosi knives the washer perforations were a little too large and could be seen when the blade is closed. Not a functional issue, but a potential point for dirt to collect. This washer design has been updated now.
 photo 45 L Inkosi blade tang P1200504.jpg

CRK have really got it spot on with the pocket clip. I generally don’t like them because they are never quite right, mainly too aggressive. In this case the tension is soft enough to be easy to use, but strong enough to hold. The bead blasted surface finish of the frame and clip give plenty of hold without being too abrasive.
 photo 46 L Inkosi clip P1200516.jpg

What it is like to use?

Ok, so this is the Large Inkosi, but how big is ‘Large’? I’ll start with my standard comparison, so here it is next to the Fällkniven F1 and a Spyderco UK Pen Knife.
 photo 52 L Inkosi size P1200557.jpg

Then just for gratuitous CRK viewing, here it is with a Pacific.
 photo 50 L Inkosi with Pacific P1200531.jpg

And in the hand. (I take XL size gloves). So it is not really all that large, it is just the larger size of CRK folder. While we are looking at it in the hand, I’m going to mention those finger grooves. It often seems that the Sebenza 21 vs 25 debate has been very polarising with owners being adamant that the they love or hate the 25’s finger grooves. I was concerned they might be problematic, but for my XL size hands, I can happily say that in all the time I’ve been using this knife I have actually not noticed the finger grooves. Clearly this is a good sign as the knife was secure in my hand but without anything digging in.
 photo 38 L Inkosi in hand P1200460.jpg

Lanyards, hmmm. Not my thing. So this was to come off, but I thought I would just note down how it was tied so I could put it back.
 photo 60 L Inkosi lanyard IMG_20160628_160656.jpg

Loosening the first knot shows it is tied like this.
 photo 61 L Inkosi lanyard IMG_20160628_161111.jpg

And repeated all the way back to the first knot round the frame spacer. And with that removed I started putting the knife to work.
 photo 62 L Inkosi lanyard IMG_20160628_161641.jpg

Although serviceable, I’m afraid the factory edge didn’t have quite enough bite for my liking, so it had a session on the Wicked Edge. Much better!
 photo 67 L Inkosi wicked edge P1250279.jpg

Recycling day was much more interesting now. Here was a large heavy duty box needing to be broken down. Made from ‘BC’-Flute double-wall heavy duty shipping cardboard, this was a bigger job than the average box.
 photo 63 L Inkosi recycling IMG_20170116_183445.jpg

Done. That was easy and enjoyable. Give me another to do.
 photo 64 L Inkosi recycling IMG_20170116_184731.jpg

The last cut through this was crisp as the blade slid through with ease. Feeling just as smooth in the cut as a full flat grind, possibly even smoother as there is less blade to material contact than with a FFG.
 photo 65 L Inkosi recycling cut IMG_20170116_184810.jpg

Outdoors and the Large Inkosi makes quick work of wood carving. Even when applying a good force to the cut, the finger grooves in the handle were not noticeable.
 photo 66 L Inkosi in the woods P1250177.jpg

CRK have taken their already time-tested design and made several improvements to it, improvements you might never actually notice in real world use, unless you push the knife to its absolute limits. I suspect many CRK owners appreciate knowing that the knife is as good as it can be and that if they really did need to push it further than normal, it won’t let them down.

The Large Inkosi is the next generation of a classic folding knife from CRK, and has been designed with such a thorough and thoughtful attention to function and detail that it is more than just a knife; it is a highly desirable object and a pleasure to use.

Special Preview: The New Large Inkosi from Chris Reeve Knives

Tactical Reviews is fortunate enough to be able to bring you a quick preview of the new Large Inkosi from Chris Reeve Knives which was launched at BLADE Show 2016. A full review will follow once I’ve been able to test it properly.

 photo 07 L Inkosi cloth P1200349 copy.jpg

The original Inkosi was designed to include improvements to Chris Reeve’s already tried and tested (and industry changing) Sebenza models. Never one to stand still, Chris knew he could improve on his original design with certain key changes to the pivot, bearing, frame and lock. Rather than apply all these changes to the established formula of the Sebenza models, a new line was created to allow these features to be incorporated into the most advanced Chris Reeve folding knife yet. With a trend to smaller more pocketable models, the first Inkosi was created as a compact folding knife, but demand has been strong for a larger version of this knife.

A look over some key design features:

At first the Large Inkosi looks very similar to the Sebenza 25, but we need to look a little closer.
 photo 09 L Inkosi angle P1200355.jpg

Notice that the stop pin as viewed from this side has no bolt head, just a rounded dome. This is actually floating on this side of the fame with a very precise fit to the hole.
 photo 12 L Inkosi pivot pin stud P1200364.jpg

The sharp-eyed will spot the pocket clip sitting differently.
 photo 14 L Inkosi lock side P1200369.jpg

To prevent the pocket clip changing the lock bar tension, it has been angled to sit onto the frame and not push on the lock bar.
 photo 17 L Inkosi clip angle P1200376.jpg

A hint at the extend to which the washer design has been improved with a very large diameter with perforations. The full review will go into this in more detail.
 photo 23 L Inkosi washer lock groove P1200402.jpg

Looking very closely at the lock-bar/blade contact point you can see the ceramic ball sitting into a groove in the blade tang providing positive engagement.

Some first impressions:

This preview is only intended to give a quick first look at this new knife, and though I’ve not been able to put it to any real use yet, the first impressions are strong.

Though the Inkosi is an excellent and easy to carry knife, living in the UK, I can only carry a lock-knife with ‘good reason’ so when I do, I prefer a larger knife. The Large Inkosi is just right.

Attention to detail is evident in every aspect of the knife’s design, and every corner and feature has been given a deliberate finish.
