Chakra Blade

A is a weapon made from special metal that absorbs the user's chakra characteristics and exhibits power based on the user's technique. Asuma Sarutobi, Sora, and Shikamaru Nara use techniques that require the use of a chakra blades like the Flying Swallow technique and Shadow Imitation Shuriken Technique. The White Light Chakra Sabre wielded by Sakumo, and later Kakashi Hatake, also had the ability to absorb their chakra and give it off as a white streak of light whenever they swung it. Nowaki kept a large number of uniquely designed chakra blades that he used to channel his wind-natured chakra. These blades were able to create explosions on impact when hitting targets while infused with his Typhoon Release-chakra.
