Irwin 2084400 Bi-metal Utility Blade

Product Description

The IRWIN 2084400 is a bi-metal utility blade engineered for extended edge life in demanding trade applications. The bi-metal construction bonds a high-speed steel cutting edge to a flexible alloy steel body, allowing the blade to stay sharper significantly longer than standard carbon steel blades. This design reduces blade change frequency on the job, making it well suited for electricians, plumbers, HVAC technicians, and general contractors who rely on utility knives throughout the workday. The blade ships in a minimum quantity of four per order.

Bi-metal utility blades like the 2084400 are used across residential and commercial trade work wherever a standard utility knife is required. Common applications include cutting insulation, stripping wire jacketing, scoring drywall, trimming pipe wrap, and general material prep. The extended blade life compared to carbon steel alternatives makes these a practical choice for high-volume cutting tasks on active job sites.
