This is not a fencing match at the Olympic Games.
If you believe that Imu is stronger than Mihawk then he can beat him in a sword fight as well.
That's not how it works lmao.
Imu uses a lot of other things from his arsenal as well.
Maki which is unknown to average character.
Punching kicking and evrrything lol.
That guy fight with every way possible. Even marksmanship.
If it's simply swords battle. MIHAWK wins.
