Tantō Dōri – Irimi Nage Preventing Tantō Draw – Tricep-Control Palm-on-Chin Entry / Rear Chin-Pull Variation

Uke carries a Tantō tucked inside his jacket on his left side (in a self-defense situation, this could be any other weapon carried at the belt, hidden in the jacket, or in the pockets). As soon as Uke reaches inside to draw the Tantō, Tori steps to the outside and places his lead hand on the upper part of Uke’s arm, above the elbow on the tricep, controlling the shoulder as in Ikkyō. At the same time, he delivers an atemi to Uke’s face, placing his open palm on Uke’s chin, extending the head backward and unbalancing him.
From there, Tori steps behind Uke and, with the same hand that delivered the atemi, secures Uke’s wrist. Maintaining this control, he releases his other hand from the tricep and moves it to Uke’s back, reaching to grasp Uke’s chin from behind the head. He then pulls the chin upward and then downward as he steps back and lowers his body, bringing Uke to the ground.
