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.  

Give your hands a break and take the strain out of cutting. These electric shears make quick work of fiberglass and carbon fiber fabrics at the push of a button. Its unique blade configuration cuts fabric with ease but can't cut your fingers. Rechargable battery provides hours of use between charges and eliminates the need for awkward or restrictive power cords. Ships complete with two sets of blades, rechargable battery, battery charger, AC adapter, and transformer. See bottom of this page for parts and accessories for the EC Cutter.
