Abstract
The self-contained force magnifying chisel disclosed herein includes a chisel portion, a striker, at least a portion of which is disposed within the chisel portion, and a spring, a least a portion of which is disposed within the chisel portion. The spring attaches to both the chisel portion and the striker. When the striker is pulled by a user, the spring stores mechanical energy. When the user releases the striker, the striker impacts on the chisel portion transferring the mechanical energy stored in the spring into a driving force. The force is magnified by a chisel blade on the chisel portion of the self-contained force magnifying chisel and applied to a workpiece.
