Wood Release: Cutting Technique

A versatile technique where the user can produce sharp wooden spikes from their body to either fashion short-range weapons akin to a makeshift sword, or else use them as long-range projectiles, where the branches' growth can be triggered remotely, skewering the enemy as a result.

Obito was able to channel this technique through the Ten-Tails' tails after he and Madara Uchiha strengthened their control over the beast by connecting to it using Hashirama Senju's DNA.

Trivia

 * Cutting, also called striking or cloning, is a method of plant propagation. It involves cutting off a piece of a plant, usually the stem or root, which is then put in an appropriate medium. If done properly, the cut piece will grow into a new plant, genetically identical to the plant it was cut from.
 * When this technique was first performed by Obito, various black receivers were scattered throughout the growth of branches that extended from his right side. However, upon deactivating his Mangekyō Sharingan and the Wood Release Technique, the rods vanished with them.
