At the clinics we had with Sherman Harrill
he used to make a point that a simple touch to the arm
led the attackers mind to that touch.
Then a strike made following that touch,
would have greater effect.
This was not the only example he used,
but I saved it from of 1996 clinic
because it made the point so well.
This is Sherman Harrill working with Garry Gerossie for the demonstration.
First a simple light strike which does not have great effect.
Then a simple touch to the wrist and the same light strike.
Not a devastating application,
just a simple principal which he used over and over
in his applications.
