Kubikiribōchō


 * Name:
 * Wielders: Zabuza Momochi, Suigetsu Hozuki
 * Debut (Anime): Naruto Episode 7
 * Debut (Manga): Chapter 10

This giant blade was used by Zabuza during his membership as one of the Seven Swordsmen of the Mist. After defecting from Kirigakure he continued to use up until his death. It was left beside his grave, where Suigetsu took it for himself during Part II.

The circle cut out of the top and the semicircle near the handle, as demonstrated by Suigetsu, seem to fit its purpose of decapitation aptly. Its handle also appears to be detachable, as Suigetsu is shown screwing it off when not in combat and reattaching it for combat.
