Description Martelli’s unique sharpening system has created a blade that is in for the long haul. The blades will last approximately three to five times longer than ordinary blades. When you replace a blade, make sure you discard the old one in a safe manner. This blade will fit most 45mm rotary cutters. Martelli blades are truly my favorite because they truly last longer than other brands. I cut lots of fabric every week and the blade I’m currently using has lasted three months.
