How would you like to have a ruler and cutter that gives you straight cuts every time? No more slipping away from the ruler for crooked cuts! No more accidentally cutting into your ruler, or running over the top! The My Comfort Cutter comes with our patented Cutter Guide. With this guide installed, the cutter interlocks to the special track on the sides of the TrueCut Rulers. As you move the cutter along the ruler's track, the guide keeps the cutter from veering away from the ruler's edge.
