folders. i heard its a bear to sharpen but holds a good edge a long time. is there any production knives with this steel?
 
Microtech made a short run of LCCs with S90V some time ago. Don't know if they made any other models with it.
 
I don't know of any knives currently in production that are using S90V. I know that some of the custom makers offer it though.
 
You can buy steel and make your knife yousef - Phill Willson doing Heat Treatment (Paul Bos unfortunately not able to HT CPM S90V because of hight temperature required - I asked him about it). I made 2 CPM S90V knives for myself just to try it - turned out it is not so expensive.

Thanks, Vassili.
 
I think Spyderco was asking around if there was interest in a limited run of knives with s90v. I'd pick one up in a heart beat if they go through with it.

DITTO!! I would buy one in a heart beat!! And to the very best of my knowledge, the only way to get an S90V knife is to either make it yourself, as someone said or buy a custom knife.
 
That's a steel that not even many custom makers use. It is not the cost of the steel, but the difficulty in working the steel that makes it unpopular. I can't imagine that anything but very special runs would be produced in this steel.

This someone was me - Nozh2002 or Vassili, second post right before your post.

Thanks, Vassili.
 
I was fortunate enough to get a S90V Apogee from DDR. Made in the year 2000. It has DDR MM engraved on the clip.
 
I also have a Kevin Wilkins mini mouse folder in S90V w/ liner locks(thick) and micarta handle. Love it!

They used S90V in the SOCOM Elites for a while, but now they're using D2.

The possible problem is that the high amount of vandium carbides make the blade nearly unsharpenable by anything but diamonds, since vandium carbide is harder than the aluma-ceramic stones like on the Spyderco Sharpmaker.

yeah ill probably have to do that, im working on grinder now, maybe it will be done in a month if im lucky. did you buy the steel directly from crucible? is it possible to buy just enough steel for a couple of blades from them?

This guys have it - http://www.mcmaster.com/
They call it old way - CPM 420V.

Thanks, Vassili.
 
S90v or CPM420v are one and the same. I had a mastersmith make me a folder out of CPM420v, he said that it is the best of all S/S only problem is that it eats belts when you grind the blade. He charged $100.00 extra to make a blade out of this steel. As far as I am concerned it is the best S/S out there. Out cuts any other blade that I have, however, very hard to sharpen.
 
Due to high vanadium contents it forms a lot og vanadium carbides - 9% or something, which are harder them aluminium oxide - this is why it eats belts so easy and so hard to sharpen and also hold an edge quite a long.

I noticed that I not able to sharpen it with Spyderco fine rods and asked here. It turns out that fine stone grind (like 3 microns???) and size of vandium carbides (like 5 microns???) comparable and so Fine stone did not really sharpen it but rip them of the edge, without making it any better.

So to sharpen it you need Diamond paste or powder on leather and then it will be just fine. Ther is also belts and jeweler powder from Silicon Carbide which is harder then Vanadium Carbide (it is used on wet sand paper), but I use diamonds - there is no things harder then that.

Thanks, Vassili.
