Armlock (腕固め, Udegatame) is a fighting move that Baki Hanma quite often used against his opponents.
At first, the user grabs the opponent's arm, and then he slams him into the ground. The fighter puts his right leg on the opponent's neck, and he keeps a balance with the other leg. With this move, the user can easly break his opponent's arm.
Baki Hanma used this technique during a battle with Kosho Shinogi for the first time. Then he used this move against Mount Toba, but he failed. Baki also made an improved and stronger version of this move. That improved version is called King Tiger.
