The OLFA® Splash Handle Rotary Cutter features sharp steel edges that get the job done quickly and efficiently. The rotary blade is made of tungsten tool steel, so it retains its sharpness, allowing it to cut through up to six layers of material at a time. That makes cutting easier on you. Besides quilting and sewing, the Splash Handle Rotary Cutter is great for medium to heavy-duty projects, everything from paper to upholstery. The handle doubles as a protective sheath, keeping the blade safe from nicks and gouges. It also keeps the sharp blade stowed for your safety when not in use. Quick blade change mechanism; no washers or nuts to keep track of when changing your blade. Contoured handle for secure and comfortable handling.
