Hasami, which means scissor, is resembled by the movement of the hands.
Hasami Uke is used to catch an attack and simultaneously execute a locking technique. This means that Uchi and Soto Uke are sort of executed at the same time, catching the attack between the arms. Remember that Uke Waza means receiving technique instead of blocking technique. Uke Waza is done to attack. Hence, it is not only important to lock instantly, but also to affect the opponents posture. We practise hasami uke in Jodan uke Nanahonme (#7).
