When employing open-hand strikes in CQC, what is the primary advantage compared to closed-fist punches when targeting the head?

The primary advantage of using open-hand strikes compared to closed-fist punches when targeting the head in CQC is reduced risk of hand injury. Open-hand strikes, such as palm strikes and hammer fists, distribute the force of impact over a larger surface area on the hand, minimizing the chance of fracturing the knuckles or wrist bones, which is a common risk with closed-fist punches, especially when striking a hard surface like the skull. This reduced risk of injury allows you to continue fighting effectively even if the strike does not immediately incapacitate the opponent. Furthermore, open-hand strikes can target vulnerable areas like the nose, eyes, and ears with greater precision and effectiveness than a closed fist. While a punch relies on blunt force trauma, open-hand techniques can cause pain compliance and disrupt an opponent's balance and vision without necessarily requiring a knockout. For example, a well-placed palm strike to the nose can cause significant pain and disorientation, creating an opening for further attacks or escape.
