Utility knife blades for carpet and vinyl

Updated: October 2026

You are on the floor with a roll of carpet or a vinyl offcut, and the straight blade that opened the boxes is tearing the sheet. Utility knife blades for carpet and vinyl are different profiles: a hook for a pull cut through carpet and felt, a straight or concave edge for vinyl and LVT. The [utility knife blades comparison](/hub/diy-supplies/utility-knife-blades) includes both packs. This page stays on floors. Peter F. used the amazon.co.uk listings on 16 October 2026 and UK flooring-trade explanations of the three profiles, not a laboratory test.

Carpet wants a hook

A hook blade cuts on the pull. You draw the hook along the line so it severs fibres instead of sawing across them. Trade guides separate hook blades for carpet fibres from straight or concave blades for vinyl and LVT. It does not mean the blade cannot cut you. One reviewer of the hook pack in this set said it will cut a hand, very deep. In this comparison the hook row is OPFYWF, £16.99, 100 SK5 blades, item length 48 mm, 4.2 from 9. Buy the profile, then change it when the cut starts to tear.

Vinyl and LVT want a finer edge

Vinyl and luxury vinyl tile mark if the edge snags. A hook that is right for carpet pile is the wrong fine edge for a visible seam. A concave blade is the curved profile for that sheet. Trade shops often sell it around 59 to 60 mm for a utility knife. Those lengths are the trade pattern, not a figure printed on the Belivy listing. When the knife is the wrong family, start with snap-off or trapezoid utility blade.

What is in this comparison

OPFYWF is the hook: carbon steel in the blade cell, SK5 in the material cell, colour cell spelled Sliver. "Compatible utility knives" is not a notch diagram. If the blade will not seat, it is the wrong knife, not a technique you can force. Belivy is the concave 100-pack at £12.99, with a black plastic dispenser and SK5 in the included line. The title says the blades fit all standard utility knives and names flooring, carpet, and vinyl. No notch count is printed, so "all standard" is a claim you check with the first blade. The wider buying order is the utility knife blades buying guide.

Cut, then stop

HSE's hand-knife guidance says you change a dull blade and cut away from your body. On carpet, that means a sharp hook and a pull you can stop, with the free hand clear of the line. If the pile frays, fit another blade rather than adding force. A paid room, a visible vinyl edge, or a staircase is the point where a fitter should take over. This page can tell you which profile the trade uses. It cannot see your subfloor. How to seat the blade, and where the old one goes, is on how to change a utility knife blade.

Common questions

Do I need a hook blade for carpet?
For a pull cut through pile, felt, or underlay, yes. Trade guides separate hook blades from the straight edge you use on vinyl. In this set that pack is OPFYWF at £16.99 for 100, 48 mm on the length cell, 4.2 from 9. One of five texts says they were not sharp enough for carpet. Change the blade when the cut tears.
Will a normal Stanley trapezoid blade do for carpet tiles?
It will cut until it dulls, and one reviewer of the Stanley listing said that happened quickly on carpet tiles. That supports changing profile, not a claim that every trapezoid fails on the first metre. For a proper carpet cut, use a hook in a knife that accepts it. Keep the trapezoid for boxes.
What blade for vinyl or LVT?
A straight or concave flooring blade, guided, not a carpet hook. Fitters score thick vinyl and snap the tile. Belivy is the concave 100-pack here at £12.99. The title says standard utility knives and prints no notch count, and the only review is 1.0. Check the first blade before you mark a visible edge.
Do the 100 OPFYWF hooks fit every knife?
The listing says compatible utility knives. It does not print a notch count. If the blade will not seat, stop. They are not snap-off segments and they are not a 1992 trapezoid. The 4.2 from 9 is a small file, and it includes a carpet return.
Is the Belivy 100-pack a flooring blade?
The title says concave blades for flooring, carpet, and vinyl, 100 of them, with a dispenser, at £12.99. Concave is the vinyl and LVT profile in trade guides, not the hook for pile. The single review is negative, and the weight cell of 0.36 g is not credible. Treat it as a profile to try, not a proven 100-pack.
How do I pull a hook without cutting my hand?
Keep the free hand off the cut line, pull only as far as you can see, and change the blade when it tears. One OPFYWF reviewer warned of a deep cut. HSE says cut away from the body and retire a blunt edge because blunt needs more force. A dull hook is not safer than a sharp one.
When should a fitter take over?
When the edge will show, when the room is a paid job, or when you are cutting a staircase or a doorway where a mistake is expensive. This page maps hook and concave onto the packs in the comparison. It does not replace a fitter's straightedge and a blade they already trust in that knife.
