Features & Applications:

These Bi-Metal replacement blades are for use with your Irwin utility knifes. These blades are produced through a patented process of combining two types of metal-spring steel and high-speed steel. This allows the blade to bend without accidentally breaking. It also ensures the blade snaps cleanly on the score every time. They are virtually unbreakable thanks to their spring steel body that delivers superior flexibility to prevent breaking.
