ABSTRACT:
An explosive actuated hand tool for cutting clean holes in sheet material, wherein the explosive force causes a piston to pull a punch toward a die, the material being located between the punch and die. Convenience and safety features include means for arming the firing mechanism by rotation of a locking ring which secures a cartridge in its chamber and means to prevent movement of a firing pin unless a lever has been moved from an OFF position to the ON position.
