Klein Tools Model 44124 utility knife blades are premium replacement blades engineered for professional electricians, contractors, and tradespeople who rely on sharp, consistent cuts throughout the work day. The triple-ground steel edges maintain their sharpness longer than standard blades, reducing the frequency of blade changes during demanding tasks like cutting wire sheathing, cable jacketing, drywall, vapour barrier, strapping, and insulation. At 2.4 inches in blade length and 0.024 inches thick, these are standard utility blade dimensions that fit most utility knives on the job site. Sold in a 10-pack, they’re a cost-effective consumable to keep stocked in your tool bag or truck so you’re never caught working with a dull blade.
