A Double-Bladed Sword (二重刃の剣, Nijūba no ken) is a type of sword used by Sanger Kazan. The sword consists of a handle that has red wrappings with two blades that are black in color on each end. The handle itself can be disconected at the middle so the user can utilize two swords. The blades are made of a special metal that can be infused through "chakra flow". When infused with wind-natured chakra the blades can easily cut through stone and even metal. When infused with ice-natured chakra the blades width, length and hardness increase.
