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!

Added few things, fixed spelling errors, several entries were correctly referenced to corresponding entries in the metallurgy glossary.

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...

Got a quote from one lab yesterday. Ouch! I was quoted 400-500$ per blade test. And I was so enthusiastic to test 2-3 different blades. Sucks of course that I do not have unlimited funding. 500$? I can buy real good custom knife for that price. Bess MTI still haven't given me a quote. If it is something normal I'd test quite a few blades, but if the price is in hundreds... My public, non profit site definitely doesn't generate revenue to cover that. Ok, now to mandatory calls and emails with Crucible and Latrobe. Another "fast" moving pair..

Phil Wilson made yet another high performance cutter for me. This time, this is a CPM M4 tool steel blade, super hard as usual, 65HRC, but tough as well. I have very high expectations for this one.

And another one for today, Moroha Usuba, also known as Ryoba usuba. Double bevel usuba in short. Quite strange combo for an Usuba type knife. Special thanks to KF's RRLOVER for the photo, and Bishamon for the description and Kanji. And with that we are at 111 entries in the database. Still nowhere near 800+ types Watanabe said exist in Japan, but on its own, it's a really good result.
