IRWIN Bi-Metal BLUE Trapezoid Blades - Pack of 10. Bi-Metal is formed by welding high-speed steel edge and spring steel, having the benefit of both types; Safety & Longer Life. The blades are safer since they will not break under normal working conditions, helping to reduce the risk of injury from breaking or shattering blades. And with Bi-Metal blades lasting longer than traditional carbon blades, they result in fewer blade changes which means fewer accidental cuts.
