A strike that is a spinning knife-hand, that can be used to pierce through what it hits. In the hands of Akira Hongō, it is a lethal weapon and one of his more prominently used techniques in variation, having the ability to use it to skewer through flesh and bone with ease. Hongō even used this for a successive strike after the "Full Rotational Defense" technique to increase its piercing force and completely gouge through a human body.
