[marvel] why are wolverine's claws so clean when they pop out?

Shouldn't they be all bloody when they pop out? and why are they so shiny?

As to why they're shiny, it's adamantium. That stuff can stay polished near forever. 

Wolverine's body adapted to the foreign material by coating them in a thin layer of mucus. Most of it stays inside, but if you're standing close enough you can feel a bit of spray when he pops his claws.
