Scratches are probably more directly related to Rockwell hardness than anything else when comparing carbon tool steels. I cannot remember which hardness Andy shoots for with his o1,but it's nothing out of the ordinary (otherwise I'd remember). Finish is also a big factor. A mirror polished blade is going to show the same scratch much more than a hand rubbed, or machine finish. I have a custom Santoku, the maker specializes in machine finishes that have fairly prominent grind lines from edge to spine. The steel is high hardness (I think it was 64hrc with a cryo) cts-xhp and doesn't seem to scratch at all.
Do I mind scratches? On my user knives (nearly every knife I have is a user)? Heck no. I eventually got rid of all of my Sebenzas and high end folders because they are like a car, they lose a lot of value the instant you use them and I just don't need that kinda silly stress. Every Fiddleback that I'll ever own will get used. Not abused, mind, but a scratch won't bother me at all.
