Shutō-uke (literally: “hand-blade block”) refers to the defensive applications of the “karate chop,” made famous by movies and television. Shutō blocks are effective because open hands allow an easier projection of one’s true strength, via the Unbendable Arm technique. It is also easier to grab an opponent following an open-hand block than it is after blocking with a closed fist. Shutō blocks contact the opponent with the shutō, the knife edge of the hand, which is the side of the hand between the wrist and the little finger. Shutō blocks are a very diverse move, which can be executed in a number of directions.
Outside shutō block
The outside shutō block is the most commonly-used shutō block, since it’s the perfect setup for grabs. To execute an outside shutō block, pull the blocking hand up to the opposite-side ear, with the palm facing inside. Cover your floating ribs on your blocking-hand side with the opposite-side hand. (This is the same position that downward-fist blocks are executed from.) Remember, everything must come in before it can go out.
Then, pull the blocking hand across the chest, until it is in front of the same-side shoulder, with the palm facing down. At the same time, chamber the opposite-side hand by pulling it across your waist to its hip, setting up a counterattack.

A good way to practice outside shutō blocks in your daily life is to use it to catch doors before they close.

Inside shutō block
Inside shutō blocks are similar to a tate shutō uchi or ude-uke. Pull the blocking hand up to the same-side ear, with the palm facing towards inside. Then, pull your elbow across your chest, until your blocking hand is in front of your face, so you can see your own palm. Your shutō will swat your opponent’s attacks away.

Rising shutō block
Rising shutō blocks are just rising blocks which connect with the shutō, instead of the forearm.

Downward shutō block
Downward shutō blocks are just downward-fist blocks performed with an open hand.
