Our unique sharpening system has created a blade that is in for the long haul. The blades will last approximately 3-5 times longer than ordinary blades. To maximize your blade life and efficiency in cutting, use it with our ergonomic rotary cutter and one of our commercial-grade mats. When you replace a blade, make sure you discard the old one in a safe manner. A good way to do this is with one of our blade tins.
