Hammerfist strike
Tettsui-uchi (literally: “iron hammer strike”), is referred to by the slang term, hammerfist. To execute a hammerfist strike, make a tight fist, and imagine that your hand is the head of a sledgehammer. Then, pound your opponent with your shutō.
Hammerfists are incredibly simple and robust, and they are the weapon of choice when delivering crushing blows to the hardest parts of your opponent’s anatomy, like the jaw, the temple, or even the skull itself. Like many of our other strikes, hammerfists are versatile, and can be thrown in can be thrown in four directions -- most of which are just more brutal versions of shutō-uchi.

Downward hammerfist strike
Downward hammerfist strikes are used to deliver crushing blows to your opponent’s abdomen and genitalia, typically when escaping from an attacker who has grabbed you from behind. To throw a downward hammerfist strike, pull your arm back sharply, as far as possible. (For best results, just throw a rear elbow strike.) Then, straighten the arm out and down in a snapping motion. The forearm should not swing freely while the elbow remains fixed in place, like a folding pocket knife. The elbow should drop down as you perform a downward hammerfist, giving it the same crack-the-whip feeling as an outside hammerfist or a winding knife-hand strike,
