摘要： An improved expandable broadhead with rear deploying blades. The rear deploying blades deploy reliably upon impact of the blades with a target. The expandable broadhead resists deflection by the target regardless of the angle of entry. Consequently, the present expandable broadhead maximizes kinetic energy on impact and increases the probability of substantial penetration into the target.

摘要： A broadhead having a penetrating, forward tip, a longitudinally extending body with threads on the rear end thereof for attachment to an arrow shaft. The body includes a single longitudinally extending passage or, alternatively, two or more longitudinally extending grooves for receiving blades therein. The blades are provided with a longitudinally extending, weight or mass reducing, slot and are held within their respective passage or grooves with transversely positioned or friction holding members which permit rearward sliding movement, resulting in outward expansion, of the blades while retaining a portion of the blades within the passage or groove. The front end of the blades extends outwardly of the body to contact the target surface and provide a rearward moving force to the blades upon such contact. The slots of the blades are formed to allow the rearward ends thereof to move outwardly to an expanded cutting position as they move relative to the holding member or, alternatively, the blades are directed outwardly by an additional transverse, camming member as they move relative to the holding member.

摘要： An expanding or expandable broadhead tip for arrows wherein a sliding body is provided to carry the blades of the arrow and allow for rotation of the blades to an expanded position. When in folded or inflight position, the rearmost ends of the blades rest on a radial surface of a stationary or positionable stop having a camming front surface and which are held in such position by a retainer. When the tip strikes an object, the sliding body moves rearwardly causing the ends of the blades to override the hold down force of the retainer and as rearward motion continues, the blades are cammed outwardly by the camming front of the stop.

摘要： A broadhead for mating with an arrow, includes a plurality of blades shiftable between a retracted, in flight position and an extended, penetrating position, each of the blades being rearwardly longitudinally translatable from the retracted, in flight position to the extended, penetrating position, each of the blades residing at least in part in a respective blade recess defined in a broadhead body when in the retracted, in flight position, longitudinal translation of the plurality of blades effecting a camming of a blade cutting edge of each blade outward relative to the broadhead body. A method of expanding an expandable broadhead is also included.

摘要： A broadhead arrow tip for placement on the end of an arrow shaft for positively positioning any number of replaceable blades and positively holding the blades within the tip body in proper alignment with the longitudinal axis of the arrow shaft. A positive locking collar, of selectable length and of various materials, is provided between the arrow shaft ferrule and the tip body with such collar and body and ferrule having formed surfaces to lock and removeably retain the blades in the body. The length of the collar as well as the material used therefore is selectable such that the weight of the tip is controllable. The forward, tip end, of the body is undercut to receive and retain the forwardly directed tips of the individual blades.
