Abstract
A wide angle arrowhead which is light weight, and which has minimal structure and surface area to decreased arrowhead weight, surface area and drag to increase performance of an arrow to which it is attached. A blade cutting edge of the wide angle arrowhead maintains an interior angle relationship to the centerline of an arrow shaft where such relationship can be fashioned to have one interior angular relationship within a specified angular range. Also, drag is minimized by the utilization of a thin ground blade cutting edge, an additional benefit of which is the decreasing of the cutting edge bluntness, thereby enhancing easy target penetration.
