Ideal for cutting multiple layers of fabric, felt and vinyl, Fiskars® Trigger Rotary Cutter (45 mm) features a high-grade, precision-ground, 45 mm premium steel blade for long-lasting sharpness. Squeeze the handle to extend the auto-retracting blade for quick use or push the button to lock the blade open for extended use. You may also use the lock to keep the blade closed for safe storage. Blade changes are faster and easier thanks to fewer loose parts, and an ergonomically sculpted handle fits your hand naturally and comfortably. This rotary cutter can be assembled with the blade on either side, providing optimal blade visibility for both right- and left-handed users.
