The TrueCut My Comfort Cutter™ 45mm rotary cutter is a top-of-the-line ergonomic rotary cutter. Its comfort curve grip is specially designed to make rotary cutting easier, safer, and more accurate. Seasoned cutters will appreciate how the handle reduces stress on the wrist and arm. Everyone from beginners to advanced cutters love the "track-and-guide" for straight cuts every time! Like all of our cutters, the TrueCut My Comfort Cutter 45mm rotary cutter works with our TrueCut ruler track to give you straight cuts every time! As you move the cutter down the ruler, the cutter's guide interlocks with the ruler track to keep the cutter from slipping off of the ruler's edge. This guide is also removable so the cutter can be used normally with any ruler without the benefit of the track and guide system. With our new quick-release system, you can change the blade on your TrueCut My Comfort Cutter 45mm rotary cutter without having to touch the blade to remove it. Just hit the quick-release summary and the blade will fall out and you can place the new blade in your cutter. TrueCut My Comfort Cutters are the most innovative, ergonomic cutters on the market. Let the My Comfort Rotary Cutter take away many of the problems you currently face with traditional rotary cutters.
