An arrowhead, spearhead, integral arrow or spear, or other projectile for hunting, with a point of efficient penetrating design and having moveable sharpened blades, pivotally mounted within a slot in the head. The arrangement provides shrouding of the functional cutting surfaces of the moveable blades when they are in a beginning, closed and positively locked position. In response to impact with and penetration into a target, the blades automatically unlock and pivot outward from the enshrouded configuration to a second position where they are fully extended and may perform their cutting function. The design is provided with options to: (1) MAKE THE ARRANGEMENT BRUSHPROOF; (2) INCLUDE AN ARRANGEMENT TO POSITIVELY UNLOCK AND DEPLOY TWO OR MORE BLADES IN SIMULTANEOUSLY; (3) INCLUDE A BLADE TRIGGERING DEVICE SO CONSTRUCTED AS TO ACTUATE BLADE DEPLOYMENT AT A PREFERRED PENETRATION DEPTH; (4) AUTOMATICALLY LOCK THE MOVEABLE BLADES IN AN OPEN POSITION ON DEPLOYMENT; AND, (5) PROVIDE AN AIR PASSAGE ARRANGEMENT FOR FACILITATING POSITIVE, RAPID INTRODUCTION OF AIR INTO THE TARGET FROM THE SURROUNDING ENVIRONMENT SO AS TO MOST QUICKLY FACILITATE PULMONARY COLLAPSE. All the foregoing functions are accomplished with a minimum of moving parts.

A sequential function projectile head comprising, in combination, a generally elongate body member having a forward end and a rearward end and being generally pointed at the forward end portion thereof for purposes of penetration of a target object, a generally elongate slot formed in said body member to extend generally longitudinally thereof, a generally elongate cutting blade having a cutting part which is sized relative to said slot so as to be disposable substantially within said slot, said cutting blade having a forward portion and a rearward portion, mounting means operatively associated with said body member and the rearward portion of said cutting blade for pivotally mounting said cutting blade within said slot, said cutting blade being pivotal on said mounting means between a closed position thereof wherein said cutting blade part is disposed substantially within said slot to an open position thereof wherein said cutting blade part has been pivotally moved out of said slot away from said forward end of said body member and toward said rearward end of said body member to expose said cutting blade part, retaining means operatively associated with said cutting blade and said body member and operable to prevent the pivotal movement of said cutting blade into said open position thereof, said retaining means and said blade being mounted for relative longitudinal movement with respect to the longitudinal axis of said body member, and triggering means operatively associated with said cutting blade and operable upon penetration of said target object by said body member to cause said relative longitudinal movement to release said retaining means, and to initiate the pivotal movement of said cutting blade to said open position thereof to expose said cutting blade part.
