The term that best translates to "center punch" is Pahl Put Ki. In martial arts terminology, "center punch" refers to a direct and powerful strike aimed at an opponent's centerline, often intended to disrupt their balance or create an opening for further techniques.

Understanding the components of the term can also provide clarity. "Pahl" typically signifies an action related to striking, while "Put Ki" pertains to the thrusting motion associated with a punch, especially directed towards the center of the opponent.
