Irwin Bi-Metal Safety Utility Knife Blades 50 Pk.

Use IRWIN® Bi-Metal Safety Blades, 50 Pack, to keep your Irwin utility knife supplied so it keeps on cutting when you need it. The bi-metal blades consist of a combination of spring and high-speed steel, giving them a sharp edge for cutting, scoring and slicing a variety of materials. Irwin bi-metal knife blades are also shatterproof and have bending flexibility so they won't snap with angled cuts. Their cutting edge lasts up to three times longer than standard carbon blades. The safety-designed Irwin utility knife blades have an innovative blunted nose, so they protect against accidental punctures. The blades also have a unique speed tip on their cutting edge that easily penetrates materials on contact. The 2.375-inch Irwin safety knife blades fit other models of utility knives as well.
