I've been playing with some open hand strikes lately while fighting in close quarters, and I think there is an aspect to open handed striking that is often overlooked. Most martial artists who train for self defense know the safety benefits of open handed striking such as lessening the risk of breaking one's hand, the option of striking areas farther from the mouth and thus lessening the risk of hitting teeth, etc. Another benefit of striking with the open hand is that it gives you an instant grip on the opponent after contact. For those of you who know the first two Jun Fan/Wing Chun Dummy sets, you will remember the part in the beginning when you transition from a palm strike immediately into a head control and inner lop sao (which incidentally resembles a common wrestling tie-up and is a good position for a variety of takedowns and strikes). Other examples are found in JKD grappling techniques where a huen sao is used to gain the inside position for a palm strike which transitions quickly into a head or body trap. The fak sao (outward knife hand) is also good for securing an outside neck grasp which is a good way to support the straight knee and down elbow spike to the spine. Furthermore, open strikes are less aversive than closed fist strikes and easy on your training partners in light sparring (used as a supplement, not a substitute for harder contact sparring with protective gear).
Just something to think about.
