How would you like to have a ruler and cutter that gave 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 raised edge on every ruler is a patented Ruler Track that interlocks to the special Cutter Guide on the TrueCut rotary cutters. As you move the cutter along the ruler's track, the guide keeps the cutter from veering away from the ruler's edge. Faster cutting of triangles, diamonds and patterns with 60 degree or 90 degree angles. This package contains one 9.75x11.25 inch triangle kite ruler. Imported.
