Conventionally, the cutting of sheet metal and other stock on a shear leaves a sharp edge. This edge must be removed for safety purposes. Typically, metal is deburred with the use of a file and a vibrator sander. Plastics, such as polyvinyl chloride (PVC), are deburred by drawing a piece of raw stainless steel over the edges.
