The OLFA RTY-2/DX ergonomic rotary cutter is made for longer cutting sessions where comfort and control matter, from piecing to trimming quilt tops. It uses a 45 mm blade with squeeze-trigger activation, automatic retraction, and a dual-action safety lock, and it is designed for right- or left-hand setup. Use it on a cutting mat with a quilting ruler, lock the blade closed for storage or travel, and change blades only with the tool secured.
