This is basically an open hand slap
that can be used in a variety of ways. There is a slight cupping of the
hand that is achieved by allowing the fingers and thumb stay together
in a relaxed curve. This cupping action magnifies the impact of the strike.
The target area is the entire side of the head. The ear and the side of
the neck are particularly vulnerable but any where on the side of the
face with produce a deep shock force to the central nervous system. This
is due to the impact received by the large number of nerve endings in
the facial area.
From a natural position that allows
you to control the space between you and your potential aggressor, simply
throw the cupped hand blow from the side of your hip straight to the target
allow your body to move in the direction of the strike by whipping in
your hips just before the blow lands.
