ABSTRACT:
An improved arrowhead features two sets of expandable blades. The expandable blades are pivotally movable from a first, concealed position to a second expanded position when spurs on the front of the blades contact a target. The first concealed position of the blades allows the arrowhead to penetrate the target upon contact. The fixed blades may be diamond-shaped, double-edged replaceable blades. The expandable blades comprise at least two pivotable blades that can be held in the first safe position by an elastic band. The spurs are located at a first end of the expandable blades, and these spurs are located proximate the base of the fixed blade portion of the arrow head, to allow the fixed portion to penetrate the target before the expandable blades are deployed by the spurs contacting the target.
