Oden uses two of the most perfectly crafted swords in One Piece. The Ame no Habakiri is one of the 21 Great Grade Swords and one of the only weapons to ever be seen to injure Kaido in his dragon form.

Named after the King of Hell, the legendary sword was forged by Kozuki Sukiyaki. It was one of the blades wielded by Kozuki Oden, and is the only weapon to ever cut Kaido deep enough to leave a scar.
