Product Description The LENOX Gold Utility Knife Blades, 50 Pack, feature high speed steel construction and a titanium coating that retains its edge longer than standard utility blades. Bi-metal construction allows the blades to stay strong without shattering even when bending and flexing. A four-notch design allows these blades to cut deeper in drywall, insulation, flooring, roofing, and more. These blades fit all standard utility knives. The Lenox Gold Titanium Edge Utility Blade has a high-speed steel edge with titanium coating that keeps the blade cutting after others have quit. The patented bi-metal construction allows the blade to bend and flex without breaking, and its four-notch system allows the blade to extend further.
