It could be that Luffy cracked Kaido's club or it could just be that it is drawing error or shading!Although,Luffy obliterating Kaido's club in the final clash would be legendary!
I think it was just an error,if Luffy did something like that Kaido would have pointed that out when he was mocking Luffy after beating him!
EDIT:it actually looks like a crack,it goes to the spike as well!
