I don't think anyone has one of their most recent knives yet, do they?
I think profile is settled. Now, O1, 52100, CPM154 or AEB-L?
I'm voting for O1, because it's just great stuff, and it feels right. If that isn't scientific, I don't know what is. In all seriousness, O1 is very affordable and performs like a friggin' champ. It's kind of got a throwback feel to it too, and 52100 just doesn't patinate enough for my liking.
