Omnigrid 45mm Pressure Sensitive Rotary Cutter 2050. The Omnigrid Pressure Sensitive Rotary Cutter works well on a variety of materials like paper, leather, vinyl, fabric, mat board and foamcore, in any direction. This rotary cutter is designed with an innovative pressure sensitive function that slides back the safety lock when subjected to slight pressure and exposes only the blade. Once you lift the cutter from the cutting surface, the safety lock slides back into place. Soft-Grip handle reduces wrist and hand strain. Tungsten-carbon steel blade double-honed for maximum sharpness. Cuts single or multiple fabrics in any direction. For left or right hand use. CHK-OG2050
