Do you have problems with arthritis, carpel tunnel syndrome, or tendonitis? Then the Martelli ErgoCutter—the only truly ergonomic rotary cutter—is right for you! Unlike traditional rotary cutters, the ErgoCutter is held in a natural position with your arm and palm of your hand evenly distributing all of the pressure. It relies on pressure from your entire arm and hand instead of just your wrist and fingers. Cuts perfect lines and angles. Blade guard closes with a flip of a finger. Each blade will last 3-5 times longer than your typical blade.
