Designed to be used in conjunction with the TrueCut Ruler, this unique duo gives you a precise cut every time. The guide keeps the cutter from veering away or slipping off the ruler's edge as you move the rotary cutter along the track. The handle design of the My Comfort cutter aligns your wrist naturally, placing power directly over the blade, eliminating stress in the wrist. The cutter has a dual action safety lock that you can open for comfort and close for safety, and also can be used right-or left-handed. As a bonus, you can customize your cutter's handle with your own photos or fabric!
