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. The Lenox Gold Titanium Edge Utility Blade fits all standard utility knives and is great for cutting drywall, insulation, flooring, roofing, and more. There are 50 blades per pack, which also includes a handy, easy-to-use dispenser to dispense the utility blades directly into the Lenox knives without touching the blade. The dispenser dispenses either one or five blades at a time and also safely holds used blades.
