No more rotary cutters veering away from your ruler! The Cutter Guide on the TrueCut 60mm rotary cutter interlocks with our patented Ruler Edge for precision and accuracy! As you cut, the track and guide keep the cutter from slipping away from the ruler's edge. Are you using a ruler that doesn’t have the TrueCut Ruler Track? No problem! The TrueCut 60mm rotary cutter will work with any ruler. You can also remove the Cutter Guide from the TrueCut 60mm rotary cutter to cut with other rulers easier. The TrueCut 60mm rotary cutter has more blade exposure than other cutters, giving you more cutting power! Cut through layers upon layers of fabric with ease. The TrueCut 60mm rotary cutter is also designed to use most brands of rotary blades already available on the market. Most other brands are compatible with the TrueCut 60mm rotary cutter, so you can get any blade and put them right in the TrueCut 60mm rotary cutter.
