ABSTRACT:
An apparatus for straightening arrowheads is designed to be used to straighten bent arrowheads so that the arrowheads, once straightened, may later be used in archery activities. To straighten a bent arrowhead, one removes or retracts any blades of the arrowhead (if possible) and attaches the arrowhead to a rotatable shaft. The rotatable shaft is free to rotate through the shaft aperture in the shaft housing, and the shaft housing is attached to the base of the device. To straighten the arrowhead, one applies pressure to the high side of the tip end of the arrowhead and, if desired, rotates the rotatable shaft so that the pressure is evenly applied to the high side of the tip end. The apparatus employs a pressure screw and a pressure band to effectively apply pressure to the arrowhead. After one or more applications of pressure to the high side of the tip end of the arrowhead, the arrowhead is checked to ensure that the arrowhead has the desired amount of straightness and that it is suitable for use in archery activities. Because straightening bent arrowheads while one is "in the field" is often desirable, the apparatus is compact and easily transportable.
