Again zoro has a sword style

Are you trying to argue that all weapons that can be used as swords are swords? Does that mean Whitebeard is also a swordsman because his weapon can be used as one? Not as important but Kaido can send cutting attacks with his club.
You do understand by that logic they also don’t have attack names because we haven’t heard of them

And again
I’m tired repeating myself
Kinda funny how someone could master a cursed supreme grade blade and even make it black but if it’s something like a scythe or knife it doesn’t matter to the wss title lol
Bladesman > swordsman
