Well bullets DO work on people who arent prepared for them. Law for example took about 9 shots to the back from doflamingo and nearly bled out from that, and kept having flashbacks of that corazon guy getting killed with them. And although enhanced, obviously, blades also clearly work as seen by luffy at marineford nearly defecating himself when he realized mihawk was about to "disarm" him (hur hur) Not too mention all the people zoro has taken out over the adventures. Speaking of law, none of the youtube videos cover it. How DID he survive all those bullets, and get his arm back and so on and so forth? Last I saw was, he was being carried off with his new nickname of lefty by cavendish, then we flash forward to when he switched luffy with violet while doflamingo was forcing rebecca to kill her because even beaten half to death, doflamingo is a sadistic bastard.
