The 60mm Rotary Cutter by Olfa performs maximum cutting with minimum strength. Have peace of mind knowing that the safety guard locks into position when not in use. The cutter is a rolling razor blade used to cut fabrics into shapes, strips and pieces for sewing, quilting and craft projects. Rotary cutters are particularly great at cutting slippery fabrics such as chiffon and lightweight satins, and well-loved by quilters for their precise cut. This cutter is specifically designed to be used with Olfa's self-healing rotary mats to prevent damage on cutting surfaces.
