Tachi Dōri – Pain/Pressure with the Tessen (Metal Fan) from Kote Gaeshi Grip

Uke strikes Shōmen Uchi with his katana. Tori, holding the Tessen in a reverse grip, raises it horizontally and secures the other end with his free hand to block the incoming strike at hand level. He then steps to the outside, positions the Tessen against the back of Uke’s hand, and grabs Uke’s wrist with his off hand, placing his thumb on the Tessen (in a similar grip to Kote Gaeshi). With Uke’s hand trapped between the handle and the Tessen, this creates intense pain, forcing him to release his katana and breaking his balance, ultimately driving him to one knee.
