Bāsuto

A dagger attached to a chain, usually wielded by holding the metal circle in one hand and manipulating the chain itself with the other. The chain can be controlled with the application of chakra.

The blade itself is capable of releasing a high-pressure burst of air that usually blows it out of anything it is stuck inside. This blast of air is powerful enough to take a 3x3 foot chunk out of a solid steel target. It is extremely useful for blowing people up. The burst of air requires the usage of chakra to activate, though not much. It can be done in succession, and used to a violent and extremely potent advantage. Even if not stuck in something, the blade can release the "air cannon" attack so long as the user wills it and has the required chakra.
