Abstract: A sample cutter includes a base plate for supporting a corrugated sample to be cut, and a pair of guide rails connected to the base plate. The pair of guide rails enable the corrugated sample to be positioned for cutting. The sample cutter also includes a slide rail connected to the base plate, and a cutting assembly connected to the slide rail. The cutting assembly is capable of moving along a length of the slide rail. The cutting assembly includes a pair of cutting blades that are capable of being spaced apart at a plurality of widths with respect to each other, and cutting the corrugated sample based on the plurality of widths.

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.
