This is the only OLFA cutter than can accommodate specialty blades — pinking, scallop/peak and wave — for decorative edging. A dual-action safety lock allows for the blade to be locked while in use or locked inside the handle when not in use. This OLFA Deluxe rotary cutter has it all: comfort, convenience, strength and safety. Its ergonomic handle with anti-slip rubber grip eliminates hand fatigue and stress, while the squeeze trigger allows the blade to self-retract for safety. Use the blade for fabric, paper, vinyl, tarp, upholstery, fleece, felt and more. The cutter can handle up to six layers of cotton fabric. To prolong the blade's life, use it with a rotary cutting mat.
