Main highlights

•Longer-Lasting Edge, Fewer Swaps: Our wide R-curve K-Hook profile spreads force across more edge, so tips don’t wear out quickly. Paired with precision-ground SK2 steel, these hook blades maintain sharpness through roofing, carpet, and cardboard tasks. Professionals change fewer blades, cut more consistently, and get better value from premium hook blades for utility knife sets.
•Multi-Angle Versatility: Designed to handle push cuts, pull cuts, scoring, and controlled-depth trimming, one blade replaces multiple task-specific tools. Slice roof shingles, lift carpet, open heavy cartons, and trim vinyl, leather, and plastic sheets with confident starts and smooth tracking. These hook blades deliver control across a wider range of materials and cutting motions.
•Precision SK2 Steel & Grind: A high-carbon SK2 formula and tight-tolerance grinding create edges that bite cleanly yet resist chipping under load. Dual curved sections keep cuts smooth on abrasive surfaces like shingle grit and dense carpet backing. The result is dependable performance from premium utility knife blades engineered for repeatable, pro-grade results day after day.
•Universal Fit, Fast Refills: Two-notch construction fits most standard utility knives and box cutters, so upgrades are seamless on the job. Pop a blade in and go. No special handle or adapter required. Whether you run a retractable, folding, or fixed utility knife, these hook blades for utility knife packs keep crews moving with quick changes and reliable lock-up.
•Heavy-Duty Value for Pros: Built for roofing, flooring, carpentry, automotive trim, and warehouse break-down, these blades last longer so you use fewer overall. Less downtime, fewer wasteful swaps, and more consistent results justify the premium over commodity utility knife blades. When dependability matters, choose refills designed to work harder and stay sharp.
•Smoother, Safer Control: The broad radius reduces sudden deep penetration common with small hooks, helping prevent accidental punctures while following your cut line. That smoother entry also lowers cutting force, easing hand fatigue across repetitive tasks. These hook blades give predictable depth control on roofing felt, shingles, carpet, and layered packaging.
