Shomen Uchi Dai-Yonkyo Omote Wasa
Forearm pin
Omote Wasa (front technique): Put your partner off balance with the Dai-Ikkyo technique and grasp his wrist while holding it in front of your lower abdomen. As if holding a sword, grasp your partner's forearm with the root of your forefinger, touching his pulse and with your little finger starting a gripping hold, followed gradually by the other fingers. Then give his forearm ample pressure using your hip power.
