ABSTRACT:
An arrowhead assembly having an adapter at the head end of an arrow shaft, an arrowhead body forming a hollow cylinder providing freely rotatable movement when the adapter shaft is inserted therein, multiple blades firmly mounted within the arrowhead body and having a shape exterior to the arrowhead body with high length to width ratio for good aerodynamic flight charcteristics and deep target penetration and a conical nosepiece fastening to the adapter shaft in fixed relation to the adapter shaft allowing freely rotatable movement of the arrowhead body and blades with respect to the nosepiece, adapter shaft and arrow shaft. The arrowhead of this invention affords ready exchangeability of the arrowhead body in which all of the blades are embedded. The front of the arrowhead body is tapered to fit within a tapered hollow portion of the noisepiece. A protective sheath and nosepiece wrench for assembly or disassembly is described.
