During his
time as a Kiri-nin, Zabuza was one of the Seven Swordsmen of the Mist, a group composed of the village's
top swordsmen. The generation of swordsmen he belonged to was noted as the strongest ever produced within Kirigakure, a further testament to Zabuza's impressive skills. Zabuza's signature weapon was the Kubikiribōchō, an over-sized broad sword, whose shape was thought to decapitate enemies. This large weapon has the
unique ability to absorb and utilise the iron from all the
blood it sheds, from whoever it cuts, in order to reform itself if damaged or broken. Zabuza was a master in its use, being capable of dispatching numerous enemies with a few slashes, and claiming that his sword "never cut a second
time", implying to have killed a large number of people with a
single attack.
