Fiskars Ergo Control 45mm rotary cutter features a unique blade design that gives both right and left-handed users blade visibility. It includes a blade that extends when the handle is squeezed and automatically retracts for safety when released, plus a thumb lock that lets you secure the blade in the open or closed position. The ergonomic handle fits your hand comfortably and the longer handle provides more control. Ideal for cutting multiple layers of fabric, paper, felt and vinyl.
