Gedan Koken Uke is a technique in Kyokushin karate. It translates to 'Lower-Level Wrist Block.' This technique involves using the wrist to block incoming strikes aimed at the lower body or legs. The term 'Gedan' refers to the lower level, 'Koken' indicates the wrist, and 'Uke' refers to the blocking motion. It is commonly used to intercept low kicks or strikes directed towards the legs or groin, deflecting them away from the body and creating opportunities for counterattacks.
