Vince, you're right. 440V is more brittle. I'm careful about it and only do it whittling on basswood, which is pretty knife-friendly wood. Even with that, I took a little bit of the side of the point... very little... off my swayback. I'm even more careful since that happened. I just happened to end up with 440v on the knives I like to whittle with.
Ed,this is just what I was told.But I also was told the 440V would be as sharp as D-2,but hold an edge better,and is ss.That is what made me specify that steel when I ordered a knife from Reese
