Seitei gata - Soete-zuki 添え手突き
From AKBAN-wiki, the Martial Arts Database
In the ninth seitei gata, while walking, the swordsman is confronted on his left side with one opponent. The swordsman turns 45° to his left, cuts the opponent's right shoulder and chest, stabilizes the blade between forefinger and thumb of his left hand and thrusts to his opponents abdomen in a horizontal stab (Tsuki) but with only a sliding step (tsugi ashi). The swordsman then practices Zanshin using a pause before shaking of the blood (chiburi) of the blade. The chiburi is done simultaneously while stepping the left leg backward. The swordsman then sheathes the sword.
