ABSTRACT:
A multipurpose tool for maintaining hunting arrows is disclosed. The tool is a sharpener capable of sharpening broadheads, a wrench capable of tightening or loosening broadheads screwed onto an arrow, and a dresser capable of dressing the fletched end of an arrow so that the arrow effectively will receive a nock. The tool has an elongated body with integral longitudinal ridges to enhance its appearance and to facilitate gripping, and is preferably molded of ABS plastic in two pieces. The sharpener and wrench are at the bottom, and the dresser is at the top of the tool. The sharpener comprises a shallow channel running diagonally across the face of the bottom, normal to the axis of the tool, with a plurality of small hard rods imbedded in the sides of the groove. Sharpening is effected by movement of the edge of a broadhead along the shallow groove. The wrench comprises a plurality of deep grooves extending radially from the axis of the tool with the deep grooves arranged so that they will receive the broadhead of an arrow that is coaixal to the tool. The dresser comprises a conical recess formed by a plurality of ribs with a hard blade imbedded in at least one of the ribs. The blade has a flat edge.
