ABSTRACT:
A rotatable arrowhead having a blade-carrying body that rotates with respect to a shaft that is attached with respect to an arrow shaft. In one embodiment, the rotatable arrowhead has a body and a tip portion that preferably rotate together with respect to the shaft of the arrowhead. The shaft extends within a through bore of the body. A portion of the shaft has a peripheral retention groove about at least a portion of a periphery of the shaft. The tip portion accommodates a retainer. In an assembled condition of the arrowhead, the retainer is positioned within the retention groove. In another embodiment, the rotatable arrowhead has a body that rotates with respect to the shaft of the arrowhead. The shaft extends within the through bore of the body, either partially or completely. The retainer can be mounted within the body or the tip portion, depending upon whether or not the tip portion rotates with respect to the body.
