The TrueCut 9.5" x9.5" rulers are great for cutting fabric for small cuts. The innovative design also helps you get a straight cut every time when paired with one of our TrueCut rotary cutters. The TrueCut 9.5" x9.5" square ruler comes with the TrueCut Ruler Track. This raised edge, combined with the guide on our rotary cutters, is what makes it possible to achieve straight, precise cuts every time. The track and guide prevent your cutter from slipping off the ruler’s edge. This amazing design helps you fully utilize the TrueCut 9.5" x9.5" by getting your full 9.5" cut without veering away from the ruler. The track and guide system works best when paired with the TrueCut rotary cutters as the TrueCut rotary cutters are equipped with a guide that locks onto the raised edge of the TrueCut ruler. You can use this ruler with any rotary cutter and still love the results it will give you. All TrueCut rulers come with an amazing track and guide system, but they also have easy-to-read marking and are made more durable than traditional rulers. TrueCut rulers are formed with an injection molded thermoplastic that makes the ruler more chip-resistant, flexible, and durable than other rulers.
