[X-Men] Does Wolverine ever have to sharpen his claws?
gpt
There's two things that make a blade not cut.  One, the edge rolls over or bends, so it's not exposed to the surface being cut.  Honing fixes this by bending it back.  Two, the edge wears down via the removal of material and becomes flatter or more rounded.  Sharpening fixes this by removing more material to restore the edge.  
The properties of adamantium are such that it is not susceptible to either method of dulling, and is also not amenable to either method of restoring the edge.  The edge it has when it is forged is the one it will always have.
