We use it ourselves! Tape your fabric edge and then cut between the two printed lines. You get an even cut and prevent fraying on both edges. This cost effective solution to fraying of expensive fabrics comes off easily and leaves a negligible residue allowing the fabric to be laminated all the way to the edge. 55 yards per roll.  

The serrated edge on these scissors allows you to cut Kevlar® without pulling fibers along with the scissor. The serrated blade holds the fabric in place while the smooth blade cuts. Can be used for other fabrics but the same pair should not be used for Kevlar®and any other fabric.
