The 60mm Rotary Cutter is perfect for both right and left hand cutting and provides for a better hold to make straighter cuts.  Also, by cupping the end of the handle in the palm of your hand, you have greater control over the device, and can hold it upright to make straighter cuts. No more cutting at an angle! Just flip the safety switch to release the blade, which comes with a safety guard. Easy to use. Makes beautiful precise cuts.
