The defensive technique with the outer hand edge is another technique that, like Uchi Uke, deflects Chūdan attacks to the outside, keeping the hands open (Kaishō posture).
Shutō uke is usually combined with the Kōkutsu-dachi stance in the Shōtōkan. Occasionally the technique is also used from Neko ashi dachi.
Shutō uke is very often present in the kata. It appears for the first time already in Heian shodan. The version with the arm extended, Tate shutō uke, additionally appears in the master kata also with the positions Kiba dachi and Fudō dachi.
