Shihō Nage with the Tantō – One-Hand Grab with Downward Strike Finish

Tori holds the tantō in Gyakute (reverse grip), the edge facing inward, and delivers an upward thrust to the midsection. Uke reacts by grabbing Tori’s wrist to stop the attack. Maintaining the upward trajectory of the thrust, Tori uses that rising motion to lock Uke’s elbow, straightening the arm and controlling the shoulder, driving the entire structure upward. This action lifts and unbalances Uke upward onto his tiptoes.
As Tori releases the upward pressure and Uke settles back toward a stable stance, he immediately seizes Uke’s arm and frees his wrist, the prior extension having already weakened the grip. He raises Uke’s arm, passes underneath it with an Enka pivot, and begins the cut characteristic of Shiho Nage.
Unlike the classical two-handed Shihō Nage, however, Tori grabs Uke’s arm with only one hand, while using the other to deliver a downward strike as Uke falls—accompanying the throwing motion with a thrust that functions either as a threat or as a finishing action.
