It's not the concept. It's just that the claws were always a Weapon X addition to Logan. But when Marvel got the bright idea that they wanted Magneto to rip the adamantium out of Wolverine, they thought...*GASP*...Wolverine won't have claws, and Wolverine without claws won't be Wolverine to the fans! (Wrong. Good writing could have made it work...something Marvel was lacking then. Deadpool, anyone? *snicker*) So they retconned the bone claws so Magneto could do his damage, but we could still have the only thing Marvel thought people liked about Wolvie.![]()
Ding!
On top of all that, every single artist made them look like branches. Why the hell would they look bumpy and gnarled, then look like blades when they're coated in adamantium?
The answer from Marvel will be that if they drew them to look like bone, keeping them white or slightly yellow, they'd closely resemble the metal claws, thus confusing readers. I guess they didn't think constant use of the phrase "bone claws" and snapping them off every other issue would be adequate clues.
Double Ding!
I mean, wtf, really?
