Which technique is identified as the knife hand block?

The knife hand block is known as "Son Nal Mak Ki" in martial arts terminology. This technique involves using the side of the hand, specifically the knife-like area of the hand, to perform defensive maneuvers against an opponent's attack. The name directly translates to "hand knife block," reflecting the nature of the movement, which emphasizes precision and control.

In practicing this technique, martial artists focus on the proper alignment and posture of the hand to ensure maximum effectiveness in blocking strikes, particularly those that are aimed at the head or upper body. The execution of Son Nal Mak Ki requires not just the physical act of the block but also an understanding of its application within a broader context, including timing and distance from the opponent.

While the other options refer to different types of blocks or techniques, none specifically denote the knife hand block. Gawi Mak Ki refers to a wedge block, We Santeul Mak Ki involves a turning block technique, and Ulgool Mak Ki denotes an upward block. Each of these serves distinct purposes in a martial arts context but does not define the knife hand block as Son Nal Mak Ki does.
