Ok, but still not convinced they would cut through Colossus' skin. If they were that strong, why didn't he use them against Namor? I mean sure, the whole dramatic "Beat him to death in an inferno" thing must've played a part, but I bet the writer's wouldn't have missed out on another wolverine-like moment if they would've been able to pierce his skin.
