"Everyone thinks shuto is a technique that uses the hand like a sword or knife, as the definition implies; therefore, the technique becomes deadlocked. The scope of the term itself is too limited to encompass the essence of traditional karate's shuro-uke. Historically, this move can push the opponent; strike the opponent's upper of middle body; strike the opponents attacking arm, or leg; block from inside to outside; grab the opponent's body, arm, or leg; hook; parry; and guard. All these possibilities are intrinsic in one technique. Modern shuto-uke's usage is completely different from traditional shuto-uke, which employed each individual part of the arm, including the back of the hand, palm of the hand, and side of the hand, as well as the entire arm itself. It is the same story for sei-ken, which should imply strike, hit, stab or nukite."
