ABSTRACT:
A safer and easier control of power to the chain by means of a hinged or flexible handle that is pressed or rotated in the direction of cut in order to drive the chain, and is released or rotated away from the direction of cut to stop the chain. This method of stopping the chain is of critical importance when a chainsaw is dropped by the supporting hand, because power to the chain is automatically stopped by the control-handle in the other hand, thereby much reducing the danger of injury or damage.
