Abstract
Abstract An arrowhead blade-carrying body for easy attachment and removal which in assembled position is between a nosepiece and the head end of an arrow shaft. The arrowhead body has a through opening centered on its long axis into which fits the head end of the arrow shaft, an adapter portion or a nosepiece shaft or a combination of these all in fixed relation to the arrow shaft. The arrowhead body of this invention allows the choice of freely rotatable movement of the blade carrying arrowhead body with respect to the nosepiece and arrow shaft or fixed position with respect thereto. The arrowhead body of this invention affords easy exchangeability of arrowhead bodies having different numbers or designs of blades on the same arrow shaft and nosepiece assembly.
