Ragnar is The Man, when it comes to Moras, I agree. But in this instance, I think Ragnar overgeneralizes in his literature for the sake of bringing his product descriptions into some terminology American will recognize. I posted to him a few minutes ago, and we'll see what he has to say. He is often slow answering his e-mail.

In the meantime, see the following. The first is a competing domsestic vendor. The second is a Swedish sources, and the third is the manufacturer of Kolstal steel.

As for S30V, I find it easy to sharpen on diamond surfaces, ceramics, or other industrial abrasives. Sure, it's tough; the reason the knives are more expensive is not just because of materials cost, it is also because it wears out tooling quicker. The same is true of D2 and any of a variety of newer 'supersteels.'

I don't have enough experience with S90V to comment. To my knowledge, the only blade I have made of it is only 1 1/2".

Now, what I am really curious about is where titanium blade metalurgy is going. I freely admit it is a knife geek sort of thing. I still hate 1090 and 1095.
