The OLFA RTY-3/DX ergonomic rotary cutter is built for high-volume cutting on larger sewing and quilting projects where thicker stacks are common. It uses a 60 mm blade with squeeze-trigger activation, automatic retraction, and a dual-action safety lock, and it can cut up to 12 layers of cotton. Pair with a self-healing mat to help extend blade life, lock the blade closed for storage, and change blades only with the tool secured.
