Sword of Kusanagi: Chidori Katana

This technique allows Sasuke to channel the Chidori through his chokutō. This makes it nearly unblockable as the radiating and chirping blade can easily cut through steel. Furthermore, if an opponent is stabbed, their body goes numb due to an electrical current which causes the muscles to contract, making it impossible for the opponent to move. However, it can be countered by other weapons that also utilise Lightning Release chakra flow, such as Killer B's swords. Sasuke has shown that he can combine this technique with Chidori Sharp Spear.
