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.
