This 3D printable blade is modeled after the one Jonin, Asuma Sarutobi, uses in Naruto. It features a combination brass knuckle and trench knife structure.
Known as a Chakra Blade, this blade is able to absorb the chakra of its user and become the origination for various attacks in the show.
This blade measures about 7 inches by 3.3 inches by .25 inches. It can be scaled up and down pretty reliably to fit your needs.
