Bi-metal utility blades built with a sharp steel cutting edge on a flexible backing, so the blade flexes instead of shattering when it is loaded from the side. Fits most standard utility knives.

• Bi-metal construction: sharp steel cutting edge on a flexible backing
• Flexible backing makes the blade shatterproof in normal use
• Fits most utility knives
• 50 blades packed in a dispenser
• Backed by the IRWIN lifetime limited warranty against defects in materials and workmanship
• Manufacturer part: 2084300

Tip: Change the blade as soon as it starts to drag. A dull blade needs more force and is more likely to slip.
