So loosely based on real weapons, but culturally it's a Wolverine rip-off, complete with a steel type sprouting 3 metal claws out its fists. And as I said, TPC just don't want the arseache of having to do a legal dance, just to pay a stipend and stop using Metal Claw to avoid paying more fees for the reference.
