The OLFA RTY-2/C Quick-Change rotary cutter is built for fast, accurate cutting in quilting and sewing projects, especially when you change blades often. It uses a 45 mm blade and supports quick blade swaps while cutting up to eight layers of cotton fabric, and the aqua handle is easy to spot on the table. Pair with a self-healing rotary mat for cleaner cuts, keep the cover closed when the cutter is not in use, and replace blades as soon as edges fray.
