Durable IRWIN bi-metal knife blades with high-speed steel edge, lasting 3x longer for plasterboard, roofing & flooring.
The IRWIN Bi-Metal Trapezoid Knife Blades combine superior strength and durability for demanding cutting tasks. These innovative blades feature a bi-metal construction, where a high-speed steel cutting edge is electro-welded to a resilient spring steel body, offering the best of both materials for exceptional performance.
The high-speed steel edge is significantly harder than standard carbon steel blades, proven to last up to 3 times longer in user trials. This extended lifespan makes them ideal for heavy-duty applications including plasterboard, drywalling, roofing, insulation, and flooring. The spring steel body provides excellent flexibility and resistance to lateral pressure, reducing the risk of snapping during use.
