It was given the nickname Raikiri after it was said Kakashi used the technique to cut a lightning bolt in two. Chidori is used for assassination purposes. Activating the body to focus chakra to the hand, Kakashi and Sasuke's hand become enveloped by an electrical force. This force is their chakra altered in nature to an electrical current. By altering the shape of the force, similar to an electrical discharge, they can decide the power and range of the attack.
