Stainles cutlery steel. Has no AISI equivalent, never the less very popular in Europe as far as I can tell. Over 2 dozen steel companies make it, and what's more fun of course, under a dozen of different names. DIN name X39CrMo17-1. I also listed exact compositions of the N335 steel from Bohler-Uddeholm and PK335 steel from Metal Ravene, both are the same X39CrMo17-1 steel.

I've mentioned before, D2 is the true champion of the knife steel composition chart. It has the most names and the most composition variations. Well, here's one more, Amtek D2. Main distinguishing feature, 1% of Cobalt in its composition. Still qualifies as D2? Amtek sure lists it as such.

Well, the day started as usual. Called Crucible Industries. Security was there. Engineering was not. VIP or VP also was not. Left messages. Hang up. Will call them again later in the day.

Another old timer in my collection that is getting used, and what's more important it's getting upgrades and mods. This time, I've added the testing results of the rehardened and reground 154CM steel Nimravus. Both mods were done by custom knife maker Phil Wilson. Now it is a superb cutter!

Fastenal lab called. They can not do non destructive test. So, I'd have to sacrifice the knife to test composition. Which I am not inclined to do at all. Still no price quote from Bess. Well, we'll see.

That extra u... Correct translations needs letter u in many cases, but popular and widespread western versions are skipping it. E.g. Gyutou is correct, but we use Gyuto, Hochou and Hoch... In short, Ryoba usuba it is.

Added Chromino 100 steel composition. Maker's name is half a mile long, you can see it in the chart. High carbon stainless cutlery steel.

Crucible underground...
Must be my lucky day. Called Crucible industries. Sales - nobody picks up. Engineering - Nobody picks up. Basically the only person picking up phone in that company is the security guy. My commendations to him for being at work all the time, but I suspect to successfully run the company you'd need more than security...
