The BSC PREFERRED 704575 is a 5-pack of deep hook utility blades engineered for heavy-duty cutting tasks in the trades. Each blade is manufactured from SK5 high-carbon steel and hardened to 56-64 HRC, giving it the edge retention needed for repeated cuts through tough materials. At 0.024 inches thick, the blades are rigid enough to handle demanding applications without flexing. Protected blade edges reduce the risk of surface damage to the material underneath the cut. These blades are a staple for roofing crews, flooring installers, and general contractors who need reliable, consistent performance from their utility knives.
These deep hook blades are designed for cutting roofing materials, linoleum, carpet, fabric, cartons, and sheet goods. The hook profile draws material into the cutting edge, improving control on pull cuts across flat surfaces. They fit most standard roofing utility knives, making them a practical addition to a jobsite tool kit wherever material cutting is part of the daily workflow.
Fits most standard roofing utility knives. Suitable for cutting roofing materials, linoleum, carpet, fabric, cartons, and general sheet materials.
Blade replacement should be performed by a qualified tradesperson following the knife manufacturer's instructions. Always retract or cover the blade before handling, and use cut-resistant gloves when changing blades. Dispose of used blades in a puncture-resistant sharps container in accordance with local jobsite safety requirements.
