Benchmade BM275 Adamas part 2: Reprofiling – From Puff Daddy to Daddy Cool !

22/08/2022 nemosandman 1 Comment

It’s time to de-shoulder that Benchmade Adamas‘s edge and to convex it a little to my own taste.
My tools are Spyderco Stuff 2 with diamonds, Fallkniven DC4 and leather strop.

First thing I will do is remove the stud which are in the way. I have found/learned that the hard way just by testing the angle, I have scratched them.

Two T6 torxs are necessary. One on each side.

Cerakote protection is found even inside the stub hole. In fact I was really tempted to remove it for good as the Adamas is so easy to open and close just by manipulating the Axis Lock button. But sometimes I need to be able to open it one hand and slowly too…

Next step is to protect each side of the blade, as I don’t want cerakote to be scratched… yet. I use white gaffer for that.

Slowly the edge is convexed and thinned. CPM Cruwear at 64 HRC is hard and diamonds are mandatory. It is a slow process all made by free hand.

Leather stropping is apply next. Again this is made slowly.

Soon this is a razorblade popping hairs just in one caress.

The Soda Bottle Butt Test was not passed in my previous test.
This is the reason I have decided to thin the edge of the Adamas in the first place.
Now it goes steady in like in butter.

The center of the butt is much thicker and harder to pass as the bottom can collapse. This is really my geometry test and many famous knives were not able to pass it.

The Adamas is now much better in terms of pushcutting and its steel (CPM Cruwear) is perfect for a thinner edge.
The stud has been put back and the big folder is ready !
Easy peazy lemon squizzy. It took me 1 hour.

The mighty Benchmade Adamas BM275FE-2 CPM – Cruwear for Flat Earth ? First glance at that Heavy Metal Hardcore Folder.

20/08/2022 nemosandman 1 Comment

Here it is the Benchmade Adamas second generation with its CPM Cruwear heavy duty blade.
It has been almost 20 years since I have reviewed one of Benchmade hardchore (made for the Military) folder. The last one was the AFCK Axis in D2 and I even think it was not upload even if it was my EDC for two years. I loved the AFCKs because, well, Sal Glesser was involved in its design with Chris Caracci and Les de Asis and Bob Terzuola and I simply appreciate Sal Glesser’s way to invent and design “matter separators”.

But here it is “Tabula Rasa” as far as I am concern ! Go figure: no hole in the blade, but holes in the handle, a gifted designer which I’m going to discover named Shane Sibert who has also designed the Bushcrafter for Benchmade… and Clive Owen’s knife in Sin City.
His signature seems to be fuller on his blade.
“I started making knives in 1994 with the idea of creating blade ware that is simple, practical and efficient. I have been a full-time knifemaker since 2004. Keeping with the theme of practicality, I avoid large metal guards, bolsters and heavy pommels to keep the knives balanced and agile in the hand. Materials have been carefully selected to ensure optimal edge retention and low maintenance. Although the knives incorporate slim handle slabs to decrease unwanted bulk and weight, the handles contour the hand for a synergistic fit. I strive to hold myself to high quality and design standards and produce a knife that will invoke pride of ownership and at the same time perform the task that it was designed for with exceptional ease.”
(quoted from Arizona Customs Knives)

You can notice slabs and hole on the handle.
Actually for such a big knife the Adamas is not that big.
The first version was release in 2011 (you can see it here on Arizona Customs Knives) and was made of D2 the new version came ten years later and with its blade upgrade to CPM Cruwear.
This steel is known to be tough ! Less than CPM3V but with a better edge retention. The Cpm Cruwear Shaman was a big hit !
Here Benchmade has heat treated the CPM Cruwear to 63-65 HRC !
This is something I need to test as it is much harder than Spyderco HRC (61-62HRC) on their CPM Cruwear blades. (Sal tested his own blade at 61.1 HRC).

Cruwear Manix 2 – (63.2 – 63.7) HRC
Cruwear Military – 62.9 HRC
Cruwear Mule (re-release) – (62.1 -62.8) HRC
Cruwear Paramilitary 2 – (62 – 62.8) HRC
Cruwear Para 3 – 61.7 HRC
Cruwear Military – 61.1 HRC

At first touch, the Adamas oozes quality and delicate attention to details. The Olive Drab G10 slabs are wonderfully tappered on both ends and the jimping is done perfectly in my book, not as aggressive as G10 Manix for example. It is palm friendly even when closed. Well done. The holes in the handle help my thumb to index the tool.. There is no hot spots. The handle is totally open and easy to clean and check for debris. It is created as a workhorse which can get dirty but still reliable.
Of course this is an expensive knife with a MRSP at $280.00 but you can see where your money has gone. It is manufactured with love.
The blade is perfectly centered on mine and there is zero blade play in any direction.
I love the Axis Lock concept since its very first Henry&Williams BM710 release.
I have never had any issue with its Omega Spring. It is easy to use with one finger when the SPyderco Cage Ball Bearing needs two finger to work. The Axis Lock makes any knife as fast as automatics. I have never had any play on mine and I have been using them since their very very first release.
I won’t do batonning with the lock engaged like some youtubers seems to do until lock failure. For record, you can do batoning with an opinel…
But engaged lock (any lock) does not like to schoked and a beating can damage an disengaged any lock even a butterfly. Knowing how to use tools in the right situation should be mandatory before doing really stupid things on video and if anyone want to use a folder for batonning some wood (stupid millennial fashion as far as I am concern) just do it with no lock engaged or learn how to bring a better tool…

But once deployed, with just a gentle flick of the wrist — axis lock with heavy blade are just extraordinary easy to deplay— the blade is shown in all its power. I understand why some youtubers would like to shove it in concrete or in bricks…. I’m not certain they will be able to peel an apple in public with it but for that kind of task a Mini Adamas has been released with the same blade thickness…. Oooh well I’m not certain the thick Mini Adamas is made for fruits either. F<or that there is another tool too: the Kapara…
The Adamas offering a 0.14″ | 3.556mm thick blade, it is designed hardcore for hard chores for folders. How will it behave, that will be in our next article but that blade surely offers a lot of lateral strength.
For now it is just a very first glance.
All specs of the Adamas can be found on Benchmade here.
You can also notice on that picture its deep carry clip which can be a nice touch for such a big heavy folder. More on that later.
The action is smooth at the pivot but needs a little breaking at the lock release; nothing some nano oil can not fix.

This is a very beautiful folder which is very well balanced, its sweet point being just under the index finger when hold in hammer grip.
It is alive in my hands.
The axis lock makes it ambidextrous and you can notice on that picture the 3 points for adapting that clip or another three screw clip (not deep carry) if needed on both sides of the handle.

The blade handle ratio is almost to 1 with the Adamas compared to the Military C36 which is known for its long handle.
Of course the Adamas came very sharp out of the box, but not as sharp as I want. The blade is protected with cerakote coating Flat Earth colored which got excellent reputation in terms of tough protecting the CPM Cruwear from rusting. Cruwear can get a patina but it is not easy.
Here Benchmade and Shane Sibert have chosen to propose a stealthy look for the soldiers which need no blade reflection under the sun too.

It is also sold with a very nice sheath offering many carry options for soldiers and hunters alike.
The deep carry clip is perfect in term of retention and ease to retrieve the big and heavy knife.
Oh it is 183 grams (5,45 oz) which is really heavy. The liners are stainless steel not titanium. This is Heavy Metal !

As you can notice the Adamas is much thicker than the C35 Military and much heavier too. Sal Glesser wanted his military to be as light as possible as a soldier got already many heavy things to carry.
Benchmade has taken another direction. The Adamas is beefierand thicker. Actually it can also been more confortable for long usage. We will see…

Another beefy released was the Shaman which almost has the same handle length. The Adamas provides a lot of edge.

Here is my good old AFCK Axis. It was used with a lot of love as you can notice. Zero issue with the lock BTW.

Now it is time to give some work to that Adamas designed to “deliver unrivaled performance throughout hard-use applications”. The next step will involve certainly some sharpening and reprofiling…
More to come soon…. But for now on, it is a knife which makes me grin when I open and close it. Kuddos to Benchmade and Shane Sibert for bringing this second gen of the mighty Adamas.

Pleasure of whittling — Which knife ?

07/08/2019 nemosandman 3 Comments

A knife and a piece of wood make my day.
I can sit and enjoy a good blade taking nice wooden chips.
Steel chemistry is important, especially how fine its grain is.
Back in the 90’s I have found how a Benchmade in M2HSS was more enjoyable than the same model in ATS-34.
How is the blade is ground is also very important, scandi makes shallower cuts when hollow grind got deeper in my experience.
But more than this: the general ergonomy of the knife and especially the spine of the blade do make a difference for me.

But let’s have a look at the knives: Ed Schemp’s Tuff and Bowie, Police 4, Yojimbo 2, Sebenza, Spydiechef, PPT, Paramillie, Lil’Native, Wolfspyder, A little TOPS scandi, Mantra2, Millie and Nilakka.

A rounded spine like my Sebenza is great. It’s very thin edge is also a plus but ATS34 is not making the moment enjoyable. Of course it will cut but the pleasure of feeling how the edge is making the chips is not there. Its edge is like a mad cow !! Hard to control.

One of the great surprise in term of pleasure has been that Lil Blue 2 from Raker (Ray Kirk). Made of 52100 ball bearing steel and brought to razor by JD !
The rounded spine of that small fixed blade makes it super enjoyable. The fine grain 52100 makes thin chips but can also be use hard for deeper cuts. That would the kind of knife you can enjoy all an afternoon without thumb soar.

A good old Opinel N°8 is able to cut deep and with power, for sure. Do I enjoy it ? Not really. It does the job but there is no pleasure when the thin spine bites my thumb during push cuts.

A great surprise and even a better surprise that my previous whittling with a Yojimbo 2 in S90V is my Yo2 Jade with a CPM M4 blade.
It is not a knife designed for whittling but it does the job perfectly. Better even is a tougher blade in CPM M4 which is very aggressive. The spine also is thick and my thumb can push with with confort and control. The Yo2 and especially that version is a great wood companion I can use with serenity.

Another knife I highly recommend for going in the woods and whittling with pleasure. And another knife with some martial pedigree has proven to be a great whittler: the PPT.
The S90V thin blade of that edition with a very confortable handle has been eating wood like a chef.

Speaking of chef: lets’ continue with the surprises. One important side of the Spydiechef is how easily it can go out of the kitchen. Sailors and sea kayakists are using it without any risk of failure but within the woods? OK mine has been convexed but this is another great tool to bring with you everywhere. I was able to create beautiful chips and the spince have not bite my thumb. Really a nice experience with this one.

My CPM Cruewear Paramillie has been convexed and its edge was really hungry for wood.
It was in all the bunch the one which went the easiest in the rod of wood. But then the square spire was so sharp and thin: it was not enjoyable. More about it later.

The Lil’ Native with JD sharpening skill is nice and powerful for its size. Really a nice you should not judge by the size. But then again, JD reground it to almost a scandi level. The belly and the thin edge does marvel for whittling. Just a tad longer blade will improved the experience but then you got a Native not a Papoose no more.

Another knife improved by JD sharpening skill is the Mantra 2. I had rounded the spine on this one and it turned to be a very powerful wood cutter. The kind of knife which disappears in your pocket and once deployed is a game changer. The very solid construction and great ergos of that Eric Glesser design is blooming in the woods.

The Police 4, as powerful as its K390 thin convexed blade was a real disappointment. The thin spine is really hurting my thumb when push cutting. The Police is and stays a very urban design. I was not really able to enjoy fine whittling with it. It does the job but the thin spine ruined it for me. This one is much better in cutting cardboards or ropes…

Of course the Nilakka is a five stars experience. nothing new: thick spine, zero ground blade. It is powerful and accurate. Pekka Tuominen knows. Just the thin point could be an issue when digging in the wood to make a hole for example. This is were the Wolfspyder shines: a very solid point !

Another great surprise in term of pleasure has been the Gent knife from Massdrop. I had convexed the edge and its S35VN rounded spined blade is just great. Its natural belly helps a lot in term of push cuts. It is a great folder and 100% shot flipper, easy to keep clean, and look at the shape of that blade: it is stunning and for less than 100 dollars shipping included. It will be reviewed.

Sorry, but the Mora has been the worst. It was not able to bring me nice chips.
I’m certain it would be a great hard used tool in the wood but here for fine gentle whittling: zero pleasure.
The synthetic handle is becoming sticky, the scandi edge is rusting and it was not able to bite in the wood. Cheap fixed blade.

So eventually, using 400 grits sandpaper, I have decided to rounded the spine of my Paramillie 2 and of course it makes a huge difference. Actually I have been really surprise in how deep It was cutting in the wood, kind of remembering its brother in 52100.
Soon I will try AEB-L steel which is considered as a stainless 52100 on a Sprint Run Urban already in transit. So more will come.

In conclusion my more enjoyable whittler is still the Wolfspyder.
The surprise joy came for the Gent, The Yojimbo 2, the Mantra 2 and the Raker.
The Paramillie with a more rounded spine will be certainly part of the club.
The biggest down was the Police 4 and the Mora.

But in term of sitting under the porche and whittling a rod the Ray Mears designed Wolfspyder is winning. It was designed for that task.

Benchmade 200 Puukko – Call me Snake.

21/01/2019 nemosandman 1 Comment

This is the first Benchmade’s review for a long time. Why ? Not because of the quality of Les De Asis company’s products but because I was not really excited by their production in the last decade after a huge love with their AFCK back in 90’s, and also with Nimravus and all those blades in M2HS which is a tungsten high speed steel, the granddaddy of CPM M4.
I still got a AFCK in M2HSS and browsing that blog, you will find it here.

So here we go, two words has caught my attention on that new Benchmade: Puukko and CPM3V.

“CPM 3V is a high toughness, wear-resistant tool steel made by the Crucible Particle Metallurgy process. It is designed to provide maximum resistance to breakage and chipping in a high wear-resistance steel. It offers impact resistance greater than A2, D2, Cru-Wear, or CPM M4, approaching the levels provided by S7 and other shock resistant grades. CPM 3V is intended to be used at 58/60 HRC in applications where chronic breakage and chipping are encountered in other tool steels, but where the wear properties of a high alloy steel are required.” Source Crucible.

COMPOSITION
C Mn Si Cr Mo V
0.80 0.30 1.00 7.50 1.30 2.75

To quote my friend Max Wedge:
“3V loses 1/3 of the toughness going from 58hrc to 60 hrc (still 1/3 above A2 at 60 hrc, and A2 is indestructible… almost). Both 4V and Cruware start to shine around 60-62 Hrc… so, 3V for choppers, 4V or Cruware for slicers, Cruware having best corrosion resistance ( trait appreciated by soldiers & foresters)”

So this tough short blade made of chopper steel is at a very good bargain !! Let see what it is all about.

The leather sheath is beautiful even (if there is a loop in the stitching… I will upgrade it into a kydex for pocket carry.) and cleverly designed as a dangler. You can remove the loop to transform it into a classical sheath.
There is a place for sparkling rod in the Bushcraft fashion. I don’t care about carry a knife of that size attached to my belt. I prefer to have it inside my pocket or my bag.

The blade is an eye candy for some reason it reminds me the small SOG Seal Pup knife with no false edge but that’s me… Is this a Puukko ?

That handle is made in some kinf of thermorun… but it is rubberized Santoprene is a soft, non-hygroscopic elastomer which exhibits excellent surface appearance, a durable soft-touch feel, excellent colorability and excellent “processability”… made by Exxon.

It is made from underground forgotten dinosaurs and jurassic biomass aka “petroleum” hence the look of scales on it ? Because that handle looks like some sort of snake or cold blood creature. I love it.

Now is this a scandi ground blade ? Nope. There is a secondary bevel. Is the knife sharp ? Yep, very sharp but could be better. Later/soon on that.

It is a hidden tang construction and you can see the steel in the lanyard hole. This knife is solid as CPM3V is really tough !!
Hidden tang are great when you work in cold weather, protecting your hand from a frozen steel.

That blade is short but handy: it asks to be used hard like… Snake Plissken’s hard actually ! Because 3V is magic in toughness ! 😀

Compared to a Mora or the Urban Hunter (from Pekka Tuominen) the Benchmade 200 stands its ground.

Here are two vision of CPM3V industrial use. Ed Schempp Spyderco Tuff is pure business. So that BM200 should be even tougher as a fixed blade.

Teamed with a Manly Wasp, you got a great combo.

But a puukko (in my book) needs a thinner edge and it is time to scratch that blade to de-shoulder all that. Diamonds do scratches but then scratches will be polished later. Thinner convexed edge is destin to go deep and get twisted; this is a tough steel.

Diamonds, ceramic and leather. Who needs more ? CPM 3V is really like chewing gum you need abrasive medium to form that convex edge.

A some compound with the leather stropping is mandatory to erase those scratches

See ? Now it is convexed and will be smooth on whittling wood. No worry for that edge stability again 3V is perfect for that use.

Standing next my Serrata which is my only naturally serrated knife.

So now, I just need some white ceramic to keep it sharp and some stropping. It is ready for testing. The Puukko shape is more for me a “Coutelas de Rahan” shape actually (French people will understand but here is the link: Rahan in Wikipedia.
making this little tough knife very appealing to bring it everywhere.
Everywhere is a good point to start. 😉

About Locks — How to choose ?

18/04/2018 nemosandman 3 Comments

wp-image-1457197829
Nowadays rendering of three iconic 90’s lock: Liner Lock, Back Lock and Integral Lock.

They are plethora of locks since the 90’s when the Tactical Folders trend started.
“Tactical” , a term which has been mainly used in a marketing way, means you can get access to your knife easily — A clip or a well thought pouch — and more important: to be able to open it and close it with one hand.
The blade needs to be locked in open position and also to stay closed while in the pocket.
Let’s have a look on the locks I prefer and use.

Maxamet Para3 Compression Lock.

The Compression Lock.
Described as:
“A lock mechanism that uses a leaf-like spring from a split liner in the handle to wedge laterally between a ramp on the blade tang and the stop pin (or anvil pin).”
What I like about that Spyderco in-house engineered system is how smooth the action is.
Spyderco is now developing and proposing flippers with the CL because the breaking action on the pivot is minimal. On my different CL folders I can open the blade in different ways: using the index, pushing the paddle to unlock the blade…
It’s fun. It depends on a detent ball to keep the blade closed.
It’s a lock easy to clean and check as the handle are all open framed. It also asked for some nested liners which, when they are skeletonized, need more attention for cleaning, especially when you use you knife in the kitchen like I do. I rinse them under hot tap water , wipe the blade and make them dry inside the pocket with body heat.
Also the compression lock can be hurting the palm of your hand when cutting hard matters.

Native 5 Back Lock.

The Back Lock.
Described on the Spyderco” Edge-U-Cation pages as: “A locking system positioned on the back of the handle that uses a rocker arm that pivots in the center. A lug on one end of the arm engages a notch in the blade’s tang to lock the blade open.”

The Manly Peak and the Native 5.
This lock has been infamous since the Buck110 and all its copycats. Spyderco has developed mainly mid-locking system which can be unlock without changing your grip lick on a Buck110. It was demonstrated with the first Native how safe it was it unlock their knife and let the choil of the blade get in touch with your finger before to close it.
This is still the way I do it, even on my Delica and Endura which got no proper choil: unlocking the blade by pushing the lock free and let the blade falling half way on your finger. The Back Lock got a spring which is strong enough to avoid a detent ball. Old timers used to pu a match inside their closed Buck110 to pass the stronger spring tension and get it open faster. On Spyderco’s, it’s also easy to avoid any locking noise just by pression the paddle before it get completely opened. Unless the blade is very heavy like on XL Cold Steel Voyager, it’s not a lock for gravity opening. But it’s one of the most solid lock. In fact because of the way it’s engaged, it can be much more solid than all the other locks. Spyderco were testing their strong back found on the Chinooks and Manix with amazing results.

wp-image-1298363584
It’s not the easiest lock to clean as there is no open framed handle. It’s hard to see if debris can be jammed in. Also it’s not the funniest lock to use as the spring tension is felt during all the opening and closing motion. The Spydies with relatively heavy handles can be spyderdropped for quick opening. I do that on my Knifecenter stainless steel spacered Delica for example. It’s also easy on your palm during hard cuts because of their closed handle spine. Some Compression Lock haters are Back Lock lovers because of that confortable handles.
Also I have noticed on many of my Back Locks knives some vertical play when cutting on board which brings us to…

The TriAd Lock
Featured on Cold Steel’s folders it is essentially a Back Lock with a stop pin. There is no more vertical play when cutting. It doesn’t change anything toward the negative force used to close the lock blade.
You can also find inside the Chaparral an hidden stop pin invisible as it’s hidden near the pivot.

The Liner Lock.
“A locking system developed by custom knifemaker Michael Walker that uses a leaf-like spring split from the liner to wedge laterally against a ramped surface on the tang of the blade.”
This lock was the king of Tactical frenzyness back in the 90’s. The Benchmade CQC7 and AFCK promoted them in titanium and Spyderco developped their Military with a stainless steel liner lock. If I remember well Sal Glesser and Les de Asis were together private students of Bob Terzuola which is a master in liner locks making before to start their own production. Depending on a detent ball, the liner lock was bringing that smoothness the Back Lock could not provide but it was not the strongest lock available.

wp-image-1554915927 Ed Schempp Euroedge strong liner lock.

To test it many people tried the infamous and stupid spine whack and many time with shock the liner was unlocked and damaged by that treatment.
It’s a very easy to lock to get open and close fast just be careful to put your finger out of the way when closing.
Titanium liner locks are wearing more than stainless steel liners.
It should not be difficult to clean depending of the handle conception. On that matter the last version of the C36 Military got rid of they spacer and got now a full open handle for easy check.

The RIL
Then Chris Reeve came with his Sebenza and used a lock bar that is integral to one of the handle scales. It was giving you the sentiment, you hand’s grasp was also enhancing the locking mechanism. It’s also a very easy mechanism to clean and check hence the Spydiechef, or the K2 which are easy to use in the kitchen even after being defiled by grease and meat…
RIL of the Advocate and the ZT550.

The PPT is a mix of both RIL and liner designs with the possibility to grasp it and hold it in opening position.

BALL BEARING LOCK
“A patented compressive lock that wedges a ball bearing between a fixed anvil and the blade tang. The mechanism also serves as a detent to hold the blade in the closed position.” I was developed by Eric Glesser for his Dodo and can be found on the Manix 2 folders with a caged ball version. Some people found a lot of similitude with the Axis Lock from Benchmade but here, instead of two omega springs, it is a coil spring pushing a ball bearing made of ceramic of stainless steel. It’s smooth but not as easy to clean as other locks. Actually I prefer it on the Lightweight version of the Manix which is my main travelling knife with its CPM110V blade. It’s engineering makes it one of the strongest as you can not squeeze a ball bearing easily and it is also self adjusting.

The cage ball can be exchange with a custom titanium cage in case of breaking after years of using. It happen to my cousin who has modeled his own resin ball.

The Balisong Lock.
This could be the most fun system to use and also the strongest. Easy maintenance, no spring… It’s a very old design. The first trace was found in 1780 in France with a knife called “Le Pied Du Roy” (The King’s Foot) and circa 1800, butterfly knives were uncommon. They were made in Paris and Thier. There is a beautiful collection of the old Butterfly Knives in the Thiers Museum. French Army troops were provided with Butterfly Knives, but after WW2 there is no more trace of Butterflies made by this brand.
(More to come in the re-edition of the Fred Perrin’s balisong review soon.)

Locking a folding blade has been a puzzle for engineers for centuries. The roman folders were not locking and 2000 years ago a folding knife’s handle was considered as an attached sheath which means it was hold like a razor: by the blade.

So how to choose a lock ? Recently I have been surprised on how well the Bulgarian Manly Peak was operating: no vertical or lateral play on its very strong Back Lock. I have been playing with the Sliverax Compression Lock flipping options. My old Sebenza RIL lock is still in great shape and my Ed Schempp Bowie flies in opening position…

Lock is just a matter of taste and use, selling a design just by its lock won’t work. Some designs are made for compression lock like the Sliverax wasp shape flipper design could not go easily with another lock.

But always remember a folder cannot be as strong as a fixed blade. Marketing can be your enemy but the main enemy of locks are shocks because its weakest element will give in, bend or broke. Now when you choose a knife made by reknown makers and manufacturers you can trust their locks but it’s not the case with all the copycats and cheap knives which often got very bad quality elements ready to break or bend at the first use. I’m not saying the best locks are the most expensive but looking for quality in the making should be mandatory in your choice.

From M2HSS to CPM-M4 — Hightech Peasant Knives and why I love them.

29/08/2017 nemosandman 7 Comments

I always wanted a Old Timer feeling on a Nasa tool. Grandpa’s knife update, a workhorse with the latest tech but asking for the same care as the previous 20th century generation used to provide to their pocket knives.

wp-image-1238144903

Back in the 90’s I was running after the Benchmade BM800HS AFCK and Mini AFCK BM812HS. (Yes, Sal Glesser was also involved in its design…) They were modern knives with titanium linerlocks but providing a High Speed Tool Steel a tungsten low chromium allow: M2 Speedstar.

wp-image-1360378706

wp-image-1626599986 The Nimravus in M2, and pictured : the mini Nimravus BM45HS.
It has been used a lot, isn’t it ?
The “M” M2 stands for molybdenum with 5% of it in the alloy and with 0.95% of carbon, 2% vanadium and 6% of Tungsten it should have been named T2.
“M2 is the “standard” and most widely used industrial HSS. It has small and evenly distributed carbides giving high wear resistance, though its decarburization sensitivity is a little bit high. After heat treatment, its hardness is the same as T1, but its bending strength can reach 4700 MPa, and its toughness and thermo-plasticity are higher than T1 by 50%. It is usually used to manufacture a variety of tools, such as drill bits, taps and reamers.”
For more info: https://en.wikipedia.org/wiki/High-speed_steel

wp-image-718990230

wp-image-129881735

Cuts in the wood were very special and left some kind of patina with M2 blades: it’s soft. Could it be the fine grain of the alloy, the tungsten carbids ? You can find set of chisels and woodturning tools in M2, some of high quality made in Sheffield, UK, but their main marketing quotes is that they last 6 times more than carbon steel which means nothing IMHO unless they use very soft low carbon steel for comparaison.
As M2HSS is not used anymore my present favorite knives are often made of CPM M4.

When the AFCK M2HSS was provided, its blade was coated. But where was the fun ? Patina is a much better coating in my book. The idea was to give to a very thin pointy knife more strenght as the current production was using mainly ATS-34. IMHO they had killed two birds with one stone by upgrading the steel to a non-stainless-steel.

wp-image-258869882 Bud Nealy Pesh Kabz or Travel Knife in M2 the coating has been removed and the Mantra 2.

I was very happy with the Caly 3 in Super Blue Steel (until I lost her) but it was not as good as HS steel. Very angry edge for sure but not lasting like M2 or of course the hyper CPM M4. So for good measure I have invested in a Endura with HAP40: “Spyderco C10WDP Endura 4 Folding Knife 3.8″ HAP40/SUS410 Satin Plain Blade, Mahogany Pakkawood Handles, KnifeCenter Exclusive”. I’m not in business with Howard of the Knifecenter but back in the 90’s I had designed their Logo !
HAP40 is an Hitachi steel which looks a lot like CPM M4 but with added 8% Cobalt and it is technically exactly what a High Tech Peasant Knife should be.
More to come when I will review it next week !

Today is the day the world mourns David Bowie.
It’s the perfect time to talk about another Bowie and another hommage: Ed Schempp’s Folding Bowie.

ED schempp Bowie

I have met again Ed at the Police National shooting range at avenue Fosh, Paris, in November. It was some kind of a mini knife show hosted by Patrick Bonetta, coutelier and keen master in sharpening. Both old friends were showcasing there their last knives, from kitchen to law enforcement duty. (Patrick will be the subject of my next articles BTW, the man desserve an entiere book !!)

Immediately Ed introduced me proudly to his last Spyderco collaboration: his bowie. What a gem !
The knife is simply oozing quality from all its pores: brass guard integrated bolster, carbon fiber handles…. a smoooooth opening. The beautiful symmetry once open and the gentle angle between the blade and the handle are trademarks of Ed’s designs we enjoyed so much on his Tuff and Persian.

This is not the first folding Bowie in the Spyderco catalog. Remember the Slysz Bowie ?
And I’m really a sucker for bowie shape blades. They got belly and they are pointy.
So deciding to put my Nilaka at rest for a while, immediately Ed’s Bowie got a ride in my front pocket.

“It has been made to be worn as a much smaller knife” Ed told me.

And he was right, the wire clip is so well designed that the knife disappears and ride deep in the pocket. It won’t be as quick draw friendly as the C36 Military, for example, but it is so discreet in this days of low profile mania.
Once open, the beautiful blade is impressive. Narrower than his Navaja but elegantly theatrical !
Again this is a Gentleman folder destin to be used served by an ‘almost” full flat ground thin blade.
At 2.5mm thick, far are the days of the 4mm hollowground Starmate (pictured here in the Gayle Bradley review).
I was not impressed by the initial factory sharpening and since I have thinned its edge to more akeen result. It was done patiently as CPMS30V is not the easiest steel to let its molecules go away…

The bottle bottom tests are now passed with flying colors. Even the mineral water bottle, thinner and easier to collapse).
The natural angle found in the Kukris is again a nice plus even with a short knife. Ed is a farmer and he creates and builds tools for his ranch.
The integrated guard was a technical requirement which is cleverly accomplished. My first knife ever was a small bowie and its guard was a PITA. I was 5 year old and I knew this knife was not well designed…
On Ed’s Bowie, the guard is nicely “anchoring” the hand as a thumb rest for example. All is smooth and gentle under your fingers. Even in hammer’s grip the small guard doesn’t come in the way.

Reverse grip either.

So if you want a small folding bowie with a great attention to details, a nice belly, a slick and smooth action, the C190CF can be your choice.
I enjoy the brass bolsters and its soft texture contrasting with the woven carbon fibers. It’s a very sensual tool with the handle resting securely in my palm avoiding any lose of grip.
Back in the 90’s they were some very long conversations on the forums about how reliable the linerlocks were. In this bowie, the handle is very rigid and the lock very well executed in Taichung. The knife has passed my tests including the carpet test which was not easy with the Spyderco Tuff. I absolutely got zero concern about the lock on this one. I got zero play lateral or vertical even with white knuckles. It is stout.
This is another ‘home run’ from Ed and another very clever hommage to a legendary design. Once in the pocket it is very addictive.
Also used in the plates, the knife is elegant and do not raise any eye’s brows even in the restaurant. A great steak knife !
