Which one? There are a number of one handed escape techniques. In my karate classes Iteach the 'windmill' to my younger students. Simply step toward the person with the grip and make a very large circle with the arm, using the shoulder as the pivot point. It torques the thumb forcing them to let go. I suspect you are looking for the JuJutsu technique, which I can't help with. I also suspect it is the smaller version of the above, thewrist roll.

Okinawans developed karate as a means of self-defense and martial training, largely influenced by their historical context of invasions and foreign occupation. The blending of indigenous fighting styles with Chinese martial arts, particularly during the Ryukyu Kingdom period, played a significant role in its evolution. Karate also served as a way to promote physical fitness, discipline, and cultural identity among the Okinawan people. Over time, it transformed into a respected martial art practiced worldwide.
