Like other OLFA rotary blades, this edge works on a variety of heavy-duty materials, including leather, fabric, and paper. Thanks to tungsten tool steel construction combined with expert honing, this blade can quickly cut through up to twelve layers of cotton fabric in a single pass. For best results and to prolong the life of the blade, always use OLFA Rotary Blades with an OLFA Self-Healing Rotary Mat.
