Professional-grade IRWIN bi-metal trapezoid knife blades with 3x longer life. Ideal for plasterboard, roofing & heavy materials.
The IRWIN Bi-Metal Trapezoid Knife Blades offer superior cutting performance through an innovative dual-material construction. These blades combine high-speed steel for the cutting edge with spring steel for the body, providing both exceptional durability and flexibility.
The high-speed steel cutting edge is significantly harder than standard carbon steel, ensuring the blades stay sharp up to 3 times longer than conventional options. This extended lifespan has been proven in real-world applications cutting through plasterboard, drywalling, roofing materials, insulation, and flooring.
The spring steel body provides crucial flexibility, allowing the blades to withstand side pressure without breaking. This makes them safer to use as they maintain their structural integrity during demanding applications. Remember, a sharp blade is often the safest option as it requires less force, giving you greater control over your cutting work.
These trapezoid-shaped blades are heat-treated for enhanced hardness and edge retention, making them ideal for professional tradespeople and DIY enthusiasts tackling heavy-duty cutting tasks. They're compatible with all standard knife handles for universal application.
