These shears are ideal to cut materials made from aramid and para-aramid fibers such as Kevlar, Dyneema, Vectran, Spectra, Technora, Nomex, Innegra, Dacron and other materials made from fiberglass and carbon fiber in rope, ribbon, thread, tape and fabric form. Its blades are made of high carbon alloy steel from Japan and are infused with Molybdenum and Vanadium (HRC 60~62) through a proprietary manufacturing process to achieve a level of hardness (HV1200) to cut high tech material. It can be used to cut materials made from carbon fiber, glass fiber, plastic, canvas, vinyl, leather, suede, leatherette, nylon, silk, cotton, for upholstery, headliner, cloth, string or other knitted forms. The cutting performance is great across the length of the blade. Quick and accurate trimming can be done with sharp edges. They can also be used to make relief cuts during the lay-up process to fit the reinforcement into the mold. Cut hanging fibers along the cutting edge of the fabric cleanly. Cut fiber thread off the fiber optic cable neatly to install connectors. Also used for splicing all type of halyards, sheets, topping lifts, lazyjacks and control lines.
