Tuscan Raider #2 – cheese and wine, boar, scorpion and Delica.

For now this post has only been edited on my smartphone. It’s more of a journal kind and some thoughts I wanted to share. It is the occasion also to share some pics of knives being used.

Once arrived in Tuscany one of the first duty of my Delica was to open a wooden crate.

Delica are thin bladed. Snapping the point is very easy.

The trick is not to apply leverage but simply to twist the blade. Even with a thin point you can apply a lot of torque. The crate was open easily.

The good thing with that knife is how well it is accepted by people and sheeples.

Tonight it has been borrowed a lot and ladies used it when a keen edge was requested.

Liver…

Boar and mash potatoes…

So far HAP40 is stainless from being used everyday as silverware. No patina has been spotted. It seems more resistant than CPM M4…

A delicacy from Naples.

Hard crust and soft inside. You need a very thin edge to cut all those blades of pasta’

The dog was playing with a scorpion. Nobody seems to care about it. But it was the chance for a bug picture…

Eventually the dog was alive despite annoying that poor scorpion for a very long time.

The scorpion escaped somewhere. Tuscany country life.

And as I’m writing now in the shade of the evening a mosquitoes has decided to taste my blood. Smallest animal are feeding in the biggest.

Sunday morning we will go hunting.

Tomorrow time to test the Euroedge.

Endura HAP40 blade and Pakkawood handle, sanded to my taste.

The tools of the trade. Leather belts, sandpaper sheaths and coffee.
As usual I cannot let ma knife as provided by the factory and Pakkawood being a synthetic ersatz of wood, I wanted to see how it reacted under the sandpaper.

P500 Metal sandpaper is used just to round the facets into rounds. The Pakkawood is soft and it’s done without any kind of discoloration. It reacts a lot like Micarata. No smell.
Anyway I was holding my breath. Those dusts are unhealthy.

“If you have a buffing wheel, try polishing the wood handle – it buffs up beautifully with a XAM or green rouge compound.” said to me Howard Korn.

Then I take the chance to sand the edge of the liners. It always great to feel an handle with not sharp edge. I have done also the same with the hole. I don’t want to chanfered it like on the AFCK but less edge makes my thumb safer. Remember, I was bite by the Tatanka hole once.

I have sand the spine to smooth it and then used some polish on leather to remove the sharpening scratches.
Eventually I have turn the Endura into a great razor which has be baptised with my blood for good measure. (I happen during the stropping…)

Spyderco C10WDP Endura 4 HAP40/SUS410 Satin Plain Blade, Mahogany Pakkawood Handles KnifeCenter Exclusive — Wooden Wonder Perfection !

wp-image-1591541194

We all know how knives get personnal items and how many times we touch them and use them. Synthetic material got their practical side but natural materials provide some spirit to a folder. It gives nobility, it gets some gentle patina over the years and it makes your personal knife much more personal and more precious. Pakkawood is synthetic but it gives than kind of feel, add a steel spacer and steel liners and you got a bank vault workhorse of the 4th generation !!
The legendary Endura and Delica has now provided as the exclusive batch at the Knifecenter and they are not only great Spyderco’s but also near perfection EDC.

First thing to notice is: this is not your regular Endura. Like the Orange Sprint Run C10FPBORE, this C10WDP is offering one of the best blade ever made in Seki: HAP40 steel clad between SUS410. HAP40 is like CPM M4 an high speed tool steel created by particular metallurgy and made by Hitachi. In my book it means a strong edge who will not chipped even if ground thin.

Quoting Spyderco: “HAP40 is a semi stainless, powdered high speed steel (HSS) that takes and holds an edge better than any other steel available on our site. HAP40 is fine-grained enough to sharpen very well and rates 64-68 on the Rockwell Hardness Test (HRC)—even harder than the traditional carbon steels used for knives. We have specified a hardness of 65-66 HRC for our blades. Unlike other HSS steels, it can be relatively easily sharpened on normal waterstones, if not quite as easily as traditional carbon steels.

We think HAP40 holds the potential to become one of the best steels on the market for the production of high quality, high durability kitchen knives.”

Edited on the 8th of  October: Semi stainless ? With 4% of chrome ?
What I can witness is that my HAP40 does not want to develop a patina yet when CPM-M4  is staining easily.

Perharps HAP40 is not a Japanese CPM-M4 but something closer to acording to CPM® REX® 45(HS)CPM® REX® 45(HS):
CPM REX 45 is an 8% cobalt super high speed steel which has excellent hot hardness along with good wear resistance and toughness, making it suitable for difficult machining applications. Made by the Crucible Particle Metallurgy process, CPM REX 45 has good machinability and grindability characteristics.Typical ChemistryCarbon 1.30%Manganese 0.30% (0.70%)*Silicon 0.50%Chromium 4.05%Vanadium 3.05%Tungsten 6.25%Molybdenum 5.00%Cobalt 8.00%Sulfur 0.06% (0.22%)Typical ApplicationsBroaches Milling CuttersEnd Mills Extrusion PunchesForm Tools Shaper CuttersGear Hobs Taps* The addition of .20/.25 S in larger diameter rounds (e.g. 2-9/16″ and over) provides a uniform dispersion of small sulfides throughout the structure, resulting in machinability and grindability benefits with no deleterious effect on toughness.”

It’s even better than my superblue Stretch in term of long last edge and certainly less prone to pit or stain. So, it’s much better.
So the fact that the blade is clad HAP40 is a good thing; you get toughness and flexibility where it counts  on the spine and rigidity where it counts on the cutting edge. (quoting Sickael a forumite)

Talking about perfection in manufacturing: the blade is perfectly centered and there is zero vertical play !

wp-image-1725366259

The steel spacer and skeletonized steel liners gives a very solid feel and a high quality feel. This is the same spacer as on the G10 Endura. It’s not butt heavy, the knife is well balanced. You can noticed how the adjustement between the liner and the spacer are perfectly done.

Of course the factury edge was on the razor side of the scale. With such a special steel it could be thinned by some work on sand paper to de-shoulder it or kept this way.

wp-image-31979110

Even if the endura doesn’t have a choil, when closed the blade falls by inerty gently on the index. Making the closing safe and fast. Perfect !

“The wood is Pakkawood which is a stabilized laminate of birch with stain, but it is the best material for knife handles. It never warps, absorbs water or changes in any way and it looks great. It also polishes up with a buffing wheel to a high gloss. They are totally made in Seki City and I love my Delica. ” Howard Korn – The Knifecenter of the Internet.
Nuff’s said. This is a labor of love. The wood is warm under the touch and provides enough traction for serious cutting job. This knife is a user, a beautiful and rare user. A classical design enhanced by the choice of materials.

Compare to the Stretch and Millie the Endura is taking her place just in between. A little thicker than my Stretch and longer too.

wp-image-594675929

Compared to my Millie, the blade is thinner but provide almost the same working edge. The Endura has always been an impressive cutting machine confirmed by years of production and refinement.

wp-image-550269868

For a must shorter handle tha the Millie, you are pocketing a blade enough long to cut bagels in half or split a melon.

wp-image-53244488

But I have found that the jimping on the blade were a little too much aggressive and by rubbing against the pocket’s lips it could ruin your denim in a week.

wp-image-377603091

It was fixed by using some diamond file turning the 90° edge…

wp-image-987220275

into a smooth rounded one. It was done in 2 minutes. This is something I also made on my Millie, Paramillie… The hump’s jimping is always catching and wearing my pocket.

wp-image-889866509

Now I prefer Tip Down carry for Spyderdrops and it gives a reason to have this holl in the clip.

So here it is: the best Endura version with a great “Wow Factor”. Even sheeples love it. It’s not menacing, it’s all in elegance and choice in refinement. This is a stunning folder and a rare Endura giving you the chance to carry a Grandpa’ knife with the last technology.

And now let’s start to use it. The kitchen is my battlefield as the knives are subject to their main purpose: cutting efficiently.

Let’s try this on code fish and tomatoes. The factory edge is “honest” but this steel begs for a thinner manifestation, better efficiency.

No stain and no risk for that hande, the wood is stabilized.

So let’s use some diamonds. De-shouldering the edge and creating an apex.
And then gently stropping on leather. The wine glass i not mandatory.
The day after I was sanding the scales !

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

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.

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-1626599986The 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.”

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-258869882Bud 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 !
