I have lots of experience with Elmax and I think M390 would be a good jump up that would behave close to Elmax. So sharpening wouldn't be a problem. Plus, I know M390 is a very tough steel. But I have been reading about S110V and I'm very interested in it's edge retention. However I see the extreme hardness as being one of it strong but weak points. Just how brittle is S110V? Some opinions would be appreciated.
