Significantly more durable than smooth-edge utility blades, these scalloped blades excel at cutting rope, carpet, cardboard, drywall, or even roofing shingles.
Made of 0.02" thick high carbon steel hardened to Rc64, the blade has excellent wear resistance, and its scalloped edge provides the tooth needed to cut tough, fibrous materials. Like bread knives, even once the tip begins to dull, the undulating edge still cuts because the valleys provide multiple sharp surfaces.
Blades measure 2-3/8" by 3/4" to fit standard utility knives. Sold in packages of 10 or 25; the 25 pack comes in a safe, convenient dispenser.
