Longsword Ninja Art — Earth Spider Sewing

Using the Nuibari, the user buries the sword's attached razor sharp wire string underground. Once a person stumbles into the area, he pulls the string to trap their feet in a formation of wire, cutting them off. The power and force behind the wires can be controlled by the user by applying additional strength.

Kakashi was able to counter the technique by landing atop the wires instead of between them. Might Guy was also able to counter the technique by using a Kunai to prevent the wires from cutting himself.

Trivia

 * The Atypus karschi spider, known in Japan as, hunts with an unusual tube-shaped web, which is partially hidden underground. When a prey lands on it, the spider bites through the silk.
