I can't wait when we learn how Mihawk earned his World Strongest Swordsman title and it was just by winning some tournament where no one else of note showed up.
All these World Strongest titles are just stupid anyway, because none of them fought all men, creatures or swordsmen in the world.
The only thing that could made sense for Mihawk's title is if it's tied to is black sword and he's really the only one on the world to achieve this sword skill, thus making him the best swordsman
