Abstract
Abstract An improved broadhead assembly for an arrow includes a lightweight hollow hub which is affixed to the arrow shaft through a mounting shaft and sleeve retainer. The lightweight hub is tapered toward the front and includes a broadhead blade receiving slot on the leading end thereof shaped to receive a plurality of such broadhead blades. These broadhead blades are adapted to be retained by the hub slot and extend forwardly thereof to provide a broadhead point which slashes into a target differently than a point which punches at a target. In one embodiment, the plurality of broadhead blades includes a pair of opposed primary blades having frontal tip portions positioned in overlying relation for added tip strength, and a pair of opposed secondary blades having tip portions adapted to tangentially abut the side of an adjacent primary blade tip while extending substantially to the forward point of the primary blade tip. In a second embodiment, three secondary blades meet by abutting each other to define the broadhead point. In both embodiments, the complete broadhead blades may be removed and replaced.
