Abstract
A manually powered fastening tool that stores and instantly releases the energy of a spring such that it forces a staple or other fastener into an object by an impact blow, wherein the operating handle is hinged near the end of the tool body opposite the end from which the staples exit. A staple ejecting plunger is unstably linked to spring actuating levers such that with the removal of a light holding force, the plunger and actuating levers are de-linked. The tool housing comprises a cantilevered rear profile.
