Abstract:
A broadhead arrowhead having retractable blades wherein a plunger of the tip of the arrowhead causes the blades to shear a shear pin and deploy when the arrowhead strikes a target. In an alternative embodiment, the blades are retained in the arrowhead by a friction fit that is overcome to deploy the blades when the arrowhead strikes a target.

Claim (Index 1):
A method for expanding the blade of a tip actuated expanding blade arrowhead, the arrowhead comprising a cylindrical ferrule, a tip, at least one blade, a hinge pin; the ferrule having a longitudinal axis, the ferrule having a passageway thereinto along the longitudinal axis of the ferrule, the tip having a shank dimensioned to pass into the passageway, the ferrule having an elongated aperture into said passageway on one side of the ferrule into which the at least one blade is positioned in the ferrule, the at least one blade having a first aperture near one end so that when the arrowhead strikes a game animal the shank of the tip is forced into the ferrule in a direction along the longitudinal axis of the ferrule to force the at least one blade to swing out from the ferrule on the hinge pin, the method characterized by positioning a shear pin through a bore in the ferrule and through a second aperture near the other end of the at least one blade, the axis of the bore being transverse to the longitudinal axis of the passageway into the ferrule, so that the at least one blade is retained in the ferrule before the arrowhead strikes a game animal but that when the arrowhead strikes a game animal the shank of the tip is forced into the ferrule in a direction along the longitudinal axis of the passageway of the ferrule to force the at least one blade to swing out from the ferrule on the hinge pin to shear the shear pin.
