What effect would Daken's claws have on Deadpool now that Daken's wrist claw is coated with a piece of the muramasa blade? 

Wait, something doesn't add up here, or is it that I'm miss informed? 
 
 Isn't that blade suppose to mess up healing factors? How is it that DAken can have it on his claws? 
 
Wouldn't that mean that the muramasa claws cuts Daken's flesh when they pop out? 
 
which means the wound isn't healing because the blade prevents that, which would end up getting infected and stuff O_O
 
Or did he do something to correct that? 

Unless it doesn't affect its wielder, then it would make a bit more sense

the murmasa claws are sheathed in adamantium remember? and im pretty sure theyd mess up deadpools helaing factor pretty bad
