Well technically the claws are.
I thought technically his regenerative abilities are his mutant power. The claws and adamantium were result of the Weapon X program....Or were the claws there to begin with and they added adamantium onto them? God, I haven't been really into X-Men since the old cartoon....I've forgotten almost everything. D:
Nope, the claws are part of him, they're still his bones which mean they were still coated in the adamantium like the rest of his skeleton though.
And yeah, healing factor is the other one.
