Kabutowari

Kabutowari is one of the swords of the Seven Swordsmen of the Mist, and is a blunt sword that is said to be able to break through any defense. It is wielded by Jinin Akebino. The sword consists of a giant axe and hammer linked end to end by flat thin leather-like rope. The wielder can first attack by striking with the axe, often driving it straight into the enemy's defense. The user can then slam the hammer downwards onto the blunt backside of the axe, using the axe like a wedge to break through the enemy's defense and onto the enemy.
