ABSTRACT:
An arrowhead includes a conical forward region (16), a pair of chisel regions (18) on opposing sides of the arrowhead (10), and a pair of wedge regions (20) on opposing sides of the arrowhead (10), wherein the wedge regions (20) are positioned adjacent and between the chisel regions (18) around the circumference of the arrowhead (10). The conical forward region (16) assists in stabilizing the flight of the arrow and in directing the arrowhead (10) into a target animal. The chisel regions (18) and wedge regions (20) enhance the arrowhead's (10) ability to pass through bone, cartilage, hide, and other difficult to penetrate materials. The chisel regions (18) and wedge regions (20) are distinct from the conical forward region (16) in that the conical forward region (16) is cone shaped around its circumference, while the chisel regions (18) and wedge regions (20) are planar in character. The wedge regions (20) are composed of a first angular region ( 26) and a second angular region (28), where the first angular region (26) has a smaller total angle than the second angular region (28). Thus, the first angular region (26) and second angular region operate in conjunction to "wedge-open" or separate bone, cartilage, or other dense matter.
