Cutting plates or otherwise called self-healing cutting mats serve as a support for cutting your leather parts (sewing) with a cutter. They are made of a very resistant material which supports the cut of a cutter very well and which closes after the passage of the blade. However, we do not recommend this type of support when using a leather punch. Usable on both sides, you are sure to use it in almost all of your leather work. Find cutting mats in A1, A2, A3, A4 and A5 format.
