We have that " Stainless Claws" described as “They might as well be made of stainless steel”, which I think would work like a sharp rock and will not wear down on wood carving, not to say make some rags.
It’s natural if there is an intelligent human sized mutant with a sharp claw, it can make some simple cutting.
And claw wear down seems like an interesting idea?
Actually if we do consider the wear down problem, then the claws may wear down on every melee attacks.
A chance of wear down on very usage and temporary lose the claw trait may mimic that?
Of course it’ll be most convinient if we have more cutting qualities to work on. But I understand that means some work.
