Shuto Uchi (knife-hand strike or open-hand strike) is a fundamental karate technique employing the blade of the palm—formed by pressing fingers tightly together, bending the thumb at the middle joint against the palm, and maintaining a straight line between wrist and hand—to strike various targets. Lion Budokan Karate International identifies five primary variations: front chop, side chop, back chop, collarbone chop, and neck chop, each differentiated by directional application rather than fundamental mechanics. The front, side, and back chops follow similar trajectories and rely on hip rotation, arm rotation, and proper distancing for maximum speed and power; the non-attacking hand remains chambered to generate hip drive. Collarbone chop extends fully with fingers pointing toward the target, while neck chop employs a slightly bent elbow with arm rotation at impact to attack neck muscles and potentially the ribs. Blind Sensei distinguishes between inside shuto (uchi shuto) and outside shuto (soto shuto), emphasizing the use of index and middle fingers for targeting and noting that preparation positions serve dual defensive functions—deflecting incoming strikes while positioning the weapon for counterattack. Both instructors stress targeting the neck, temple, collarbone, and side of head as primary objectives, with Lion Budokan noting that shuto can interrupt opponent arm strikes during defense. Proper stance maintenance and elbow positioning prevent loss of power and structural integrity during execution.

Frequently Asked Questions
How do I keep my arms safe and maintain good form when executing shuto uchi?
Keep your elbows up high to avoid losing arm position, and maintain your guard without hiding behind your arms so you can see what's happening in front of you. Your movement should follow a straight line, with one hand attacking while the other comes behind and above your hips as you alternate.
What's the difference between a neck chop and a collarbone chop shuto?
Both start from the same position, but a neck chop uses a slightly bent elbow and requires you to turn well in advance, while a collarbone chop is fully extended with a straight arm. The bent elbow on the neck chop is necessary because you are attacking your opponent's neck specifically.
