Channel Chakra Natures
|Created in Which World||Ninja World|
A highly uniquely-designed trench knife, these blades are worn like brass knuckles, but each one has a sharpened zigzag "tooth" over each knuckle, and a blade coming out of one end. The knives are made from a special metal that can be infused through "chakra flow" with elemental chakra or Yin-Yang chakra to produce added effects.
Asuma Sarutobi couples these knives with his taijutsu skills to great effect, such that he can take out nine Otogakure ninja in a matter of seconds. When infused with wind-natured chakra, it can easily pierce through stone.
