US Patent 7320266 Shock dampening counterbalanced handle

Shock dampener incorporated into a hammer handle. Using a counter weight attached with a hinge pin to provide extreme shock dampening when striking solid objects with a hammer tool. Shock travels in waves known as vibration. When striking an object with the hammer's head, a shock wave is created and travels down the handle. The shock wave travels through the whole hammer handle at one time in an instant. This allows for energy of the shock to transfer into the counterbalance dampener hinge pin and vibrate the dampening member that is buffered with a form of rubber diffusing 95% of the shock energy with the dampening member.
