Scissors for glassfibre
Fiberglass is (like carbon) a very abrasive material to cut. It will wear the edge of a shear quickly. For cutting materials like fibreglass and carbon, you need scissors made of strong steel with a cutting angle set to a degree that can handle something this damaging to the edge. One side serrated for a sharp cut. Available in a wide range from 15 cm normal duty to 30 cm heavy duty.
