Samehada

The Daito, Samehada, is one of the 7 blades the were originally wielded by the 7 Swordsmen of the Mist. After defeating the former wielder of the blade in combat, and then paying off his conniving Mizukage, Bocchiere gained this blade for himself. Rather then cutting like a normal blade, Samehada shreds and shaves it's enemies, due to the scales along it's length. It is as tall as a man and is normally bound by cloth. When unbound it is shown to be much wider and covered from hilt to point in scales, at the tip of the blade their is a mouth, with teeth and a tongue. One can store items within Samehada's mouth as well. The hilt of the blade can also twist and extend, allowing Bocchiere to wield the sword like a flail. It can cut through and absorb chakra, even the dangerous chakra of a bijuu, and the sword can partially fuse with Bocchiere to give him access to it's stores of chakra or even heal great damage.
