.... Wolverine's bone claws. Sure, I was just as shocked as everyone when I first saw them popped after the Magneto incident, but really, it is a lame idea. To me, it was a better story that the Weapon X program was sadistic enough to implant the claws in him to make him a more efficient killer.
Actually, they didn't. The claws grew themselves, as a subconscious extension of Logan's animal instincts in reaction to what they were doing to him. In effect, his body sucked extra adamantium into his wrists and created the claws as a defense mechanism. What they were doing to him was extremely painful, and his mutation was the only thing that kept him alive (they got that part right in the movies, at any rate).
The doctor was pretty clear on that at one point in the story, after Logan kills the first person that stepped into the room with him after the procedure. The young assistant is panicking and screaming about the "knives" that Logan grew, and the doctor calmly explains their origins and that they are, in fact,
claws, and most definitely NOT knives. They did NOT have a sharp edge, as many artists (and the movies) have drawn them. He didn't cut people, he ripped them.
There was no mention of bone claws in the original Weapon X storyline (which is the only one I consider canon). They would have seen them in the x-rays, of course. That, and the fact that he bled profusely every time they extended, until the scar tissue built up. And that it took him a while to learn how to control them, to extend them at will instead of only by instinct.
I stopped reading the Wolvie comics when they began to retcon the Weapon X storyline, around issue 100. Every time they tried to "explain" what was "really" happening during Weapon X, it just made it that much LESS awesome. Weapon X was the perfect origin story, all that the character needed, and they had to go messing with it. As a direct result, I ignore anything about bone claws or any of the crap that happened in the
X-Men Origins: Wolverine movie.
