Blade of Wind

Baki emits chakra from his fingertips, creating an invisible sword out of wind that he attacks opponents with. Because opponents can't see it, and because of how precise Baki can be with his attacks, there is little opponents can do to defend against this technique. The Blade of Wind is to the Sickle Weasel Technique what a longsword is to a kunai.

Trivia

 * In the anime, the technique is seen being used in rapid succession in the form of disk-like projectiles with 'streams' of wind following its rotation. It had enough power to launch a grown man several feet into the air.
 * In Naruto: Clash of Ninja Revolution 2 and 3, the attack takes on a drill-like shape.
