Imagine for a moment you are out with your friends and some big, obnoxious, drunken fool decides he wishes to dance with you. After you politely turn down what he considers a generous offer, he becomes belligerent and wraps a big meaty hand around your wrist. This is called a wrist grab and when it comes to brute strength you know you will probably lose. A wrist grab is fairly easy to escape when you combine the torque of your body with a sudden twisting movement of your hand against your captor s thumb. You wish to work against the thumb because it is the weakest point in his grip.
Wrist locks are a horse of a totally different color.
A small amount of pressure can cause severe pain in the person being held while the appliance of more pressure can actually break the wrist itself. The beauty of a wrist grab is that most techniques depend upon the victim fighting the hold. While trying to fight, a person being held tightens the muscles and tendons in his or her hands and wrists. By doing this an opponent is given the advantage of basically disabling you due to the pain radiating from your wrist into your hand and arm so the best thing to do is not to give him the upper hand. When you stay calm you can allow your arm, wrist and hand to relax and go limp.
