Hassō-shutō uchi
Hassō-shutō uchi literally translates as "all-eight directions knife-hand strike," because of it's versatility to hit different targets from different positions. This is the famous "karate chop", though within Goshin-Jutsu, hassō-shutō uchi, is commonly called a downward knife-hand strike.
Starting from a chambered position, raise your hand up along your torso to shoulder level. Then extend your arm directly forward, with your elbow pointed down, and your fingers pointed up, striking the opponent with your shutō. At the same time, chamber the opposite-side hand.
Do not fix your upper arm in front of you and madly swing your forearm with your elbow alone, as though you were performing a culturally-insensitive baseball cheer; there is no power in such a technique. In a correct hassō-shutō uchi, the elbow moves from guarding the floating ribs up to shoulder level; like a scissor jack.
