Abstract
A blade-opening arrowhead device includes an arrowhead body having a plurality of longitudinal blade slots on an outer surface and a flexible wedge slot extending through a center portion of the body. A blade is pivotally disposable in one of the blade slots and pivotable between a retracted position and a deployed position. A flexible wedge is disposable in the flexible wedge slot. The flexible wedge is configured to apply a wedging force against the blade in the retracted position to maintain the blade in the retracted position until a sufficient external force overcomes the wedging force and pivots the blade to the open position.
