A Chakra Blade (チャクラ刀, Chakura Tō) 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 chakra blades like the Flying Swallow and Shadow Imitation Shuriken Technique. The White Light Chakra Sabre wielded by Sakumo, and later Kakashi Hatake, had the ability to absorb chakra and release 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.
Katasuke Tōno of Konohagakure's Scientific Ninja Weapons Team invents a chakra blade that uses the wielder's chakra to generate a makeshift blade (but has the downside of draining too much chakra too quickly), and allows Boruto Uzumaki to handle a prototype.
- Asuma taught Naruto Uzumaki the fundamentals of the wind nature with these blades during Naruto's Wind Release training.
- In Naruto Shippūden the Movie: The Lost Tower, it was revealed that Konohagakure has a standard chakra blade that is used by some shinobi.
- Shikamaru would eventually pass on Asuma's blades to the latter's daughter, shortly after she was promoted to chūnin.
- Ao has a similar weapon in his possession, albeit a two-bladed one, which is hidden within his prosthetic left arm.
