US Patent 8043178 Broadhead for bow hunting arrow

The broadhead for bow hunting arrow is an arrowhead having: a ferrule; a plurality of planar, generally triangular blades extending radially from the ferrule; a fitting for attaching the arrowhead to an arrow shaft; a pointed tip; and a ring or annular blade mounted to the outermost edges of the triangular blades. In one embodiment, the triangular blades have notches defined therein, and the ring has slits corresponding to the triangular blades extending into the body of the ring that the upper legs of the notches engage to prevent rotation of the ring. In another embodiment, the triangular blades have slots and the ring has slits extending into the ring with the slots engaging the slits to prevent rotation of the ring. Alternatively, the ring may be fixed to the triangular blades by welding or by any other means. The broadhead is particularly well suited for hunting large game animals.
