Abstract: A self-centering nock is provided for use in a well-balanced nock-arrow or nock-bolt assembly. The self-centering nock includes compliant projecting protrusions or compliant arms that are substantially rotationally symmetric about a cross section normal to a main axis of the self-centering nock. The compliant projecting protrusions or compliant arms may be received in bolts that have bores of differing internal dimensions.

Abstract: Designs for expandable broadhead arrowheads with chisel tips for attachment to arrow shafts are provided. The chisel tips, when inserted into the ferrules of the expandable broadheads, provide greater durability, improved flight characteristics for the projectile to which the broadheads are attached, and more effective deployment of the cutting blades of the expandable broadheads.

Abstract: The crossbow bolt or arrow nock in certain embodiments of the current invention includes a structural support piece that substantially surrounds and structurally supports the distal end of the nock, which may be made of a clear polymeric material to allow the transmission of light.

Abstract: Collars are provided to facilitate retaining the blades of a broadhead in their in-flight position during flight. Collars can be used in situations where the preexisting use of an O-ring is used to help facilitate maintaining the blades of a broadhead in their in-flight position during flight. Collars can also be used in situations where the preexisting use of an O-ring is not used to help facilitate maintaining the blades of a broadhead in their in-flight position during flight.

Abstract: One embodiment of the present invention is directed to a broadhead assembly that includes a ferrule having a shaft engaging end, an opposed tip end, and an axially extending elongate body. The tip end is formed as an integral part of the ferrule and includes a plurality of facets circumferentially arranged about the axially extending elongate body. The facets are tapered rearwardly and outwardly relative to the tip end and form a tip base that is positioned at a forward portion of the elongate body.

Abstract: 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.

Abstract: A frame is provided, and a quiver assembly is attached to the frame. The frame, preferably made from aluminum, is manufactured by using an axis of extrusion that is perpendicular to the primary axis of the quiver assembly. A top portion of the quiver assembly provides blade covers with foam inserts to store, for example, expandable broadheads. The blade covers arc non-circular in shape, so that broadheads can he rotated approximately ninety degrees to a secure position. The quiver also utilizes a set screw that allows a the hunter to adjust the camming force required for loading and unloading the quiver from the bow. The quiver assembly utilizes rubber posts that allow for a quiet operation, as well as a secure means of locking the quiver assembly to a bow.

Abstract: 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.
