Ideal for cutting multiple layers of fabric, felt and vinyl, this cutter features a titanium blade coating that is 3x harder than steel for exceptional durability. The 45 mm blade is made of high-grade, precision-ground, premium steel for long-lasting sharpness. A sliding button extends and locks the blade for secure use, and a push-button retracts the blade for safe storage. Blade changes are faster and easier thanks to fewer loose parts. A curved loop-handle design with SoftGrip(R) touchpoints provides a natural fit for your hand, improves comfort and control, and allows you to securely hold the cutter while positioning materials. This rotary cutter can be assembled with the blade on either side to provide optimal blade visibility for right- and left-handed users.
