Lightning Cutter (Batman5295)

The Lightning Cutter is an enhanced and concentrated form of the Chidori with the same effects and drawbacks.

Overview
According to Might Guy, it 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 the anime). In Part I, Kakashi is limited to using it four times in one day, but by Part II, he can use it at least six times in one day.

Usage
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 Kakuzu's Lightning Release: False Darkness.

Kakashi later demonstrated the ability to imbue a projectile weapon, such as a kunai, with his Lightning Cutter, granting the technique long-range capabilities. In this instance, the kunai was capable of piercing through multiple large rocks with ease, without any loss of momentum or change in trajectory.
