I put a carbon fiber clip on mine as a lark. Probably not a good move, though, as flimsy CF clips have a tendency to crack and it's not my favorite clip to begin with. Beyond changing the clip or regrinding the blade (REK will probably hook you up if that's what you're looking for) there isn't much left to do to it. It's a nested liner CF handled knife with blue anodized standoffs already . . .
