Lightning Cutter

The Lightning Cutter is an enhanced form of the Chidori with the same effects and drawbacks, but more concentrated. It is said to have gained its name after Kakashi split a bolt of lightning with it. Because the Chidori is already powerful on its own, the Lightning Cutter requires better chakra control, which is exemplified in its appearance. The Chidori appears as simply a mass of white electrical chakra in the user's hand, while the Lightning Cutter is more focused and blue. In Part I he is limited to using it four times a day, but by Part II he can use it at least six times.

Kakashi has shown different ways of forming and using the Lightning Cutter. During his confrontation with Orochimaru in Part I, he creates it without using hand seals. In Part II he is able to form a Lightning Cutter in both of his hands to counteract Lightning Release: False Darkness.

One day, while he was still a young man, he was taking shelter under a tree, as it was raining. Suddenly, a bolt of lightning struck him. However, Tachibana used his Chidori to cut the Thunder God inside the lightning bolt, allowing him to survive. After this incident, he renamed his Chidori to.
 * Perhaps an error in the anime, but during Kakashi's final battle with Zabuza, he said that this was his one and only original technique, but if he invented Chidori before that, then it was not his one or only original technique.
