Utility knife buying guide
Updated: 24 October 2026
You are looking at a search page that mixes kitchen knives, sharpeners, and pocket tools with the cutter you need for a carton, a sheet of plasterboard, or a roll of carpet. A utility knife buying guide starts with the material, then the blade, then whether that blade stays seated. Peter F. read the seven kept amazon.co.uk listings on 22 October 2026 and did not run a lab test. The [utility knife comparison](/hub/hand-tools/utility-knife) is the table of those listings, with prices in GBP. This page is the order of the decisions. A qualifying purchase can earn us a commission at no extra cost to you.

What counts as a utility knife
A utility knife, as a UK decorator or a warehouse buyer means it, is a hand cutter with a replaceable or snap-off blade for sheet, card, film, or flooring. It is not a santoku, not a sharpening stone, and not a camping multi-tool. The Health and Safety Executive’s note on hand knives says you should specify the knife for the task, keep spare blades available, and prefer a retractable blade where a point is not required.
In this set the Dekton DT60126 at £7.13 is three retractable 18 mm knives. The Stanley FatMax FMHT10501-0 at £17.52 is named for carpet, flooring, and drywall, with room for 10 blades. The Milwaukee Fastback 48-22-1505D at £40.90 is a folding 2-pack with a wire stripper and a 1/4 inch bit holder. The Draper 90503 at £2.99, the yellow TNCIAD pair at £5.99, and the Reyuvidep set at £4.29 are parcel tools. The Edma 170155 at £12.51 has one review, so it shows spare storage rather than a type you should rank.
Blade shape and width
BuildWiz’s UK blade notes treat a trapezoid as the stiff general blade for plasterboard, insulation board, and sheet, and an 18 mm snap-off as the blade you refresh when the tip dulls. Sollex puts 9 mm on paper, wallpaper, and film, and 18 mm on board, flooring, and drywall. A hook blade is the shape for carpet and membrane, where a straight tip would stab what is underneath. None of the seven listings prints a hook blade as a supplied edge, so do not assume the Stanley’s alloy-steel blade is a hook until you see one in the box.
If you are choosing the mechanism rather than the width, open snap-off versus retractable. A trapezoid does not become an 18 mm snap-off because both get called a Stanley knife in conversation.
Spares, lock, and handle
The cut fails when the edge is dull or the blade is loose, not when the handle colour is wrong. PPS12 says spare blades should be available and that you should not leave loose blades on the bench. A named lock is rarer than the word safety on the title. Dekton says retractable and does not name a lock. Edma is asked about a safety lock and does not answer. The Stanley changes blades with a thumb wheel and does not say the blade retracts. The Milwaukee names a press-and-flip opening and does not name a lock button. If the retainer will not hold, stop using that knife.
What to spend
The prices named above are amazon.co.uk shelf prices on 22 October 2026. A dearer knife does not cancel the carrying rule in England and Wales.
Paying £17.52 for the Stanley makes sense when the job is carpet, flooring, or drywall and you want blade slots in the handle. Paying £40.90 makes sense when you want two folding knives plus a stripper and a driver, and you accept that the written reviews are not UK-marked. Paying £7.13 makes sense when you want three 18 mm knives and you can live with the retention complaints. The ceramic set is a keyring cutter, not a cheaper trade knife. The Draper at £2.99 is the best value here for tape and film, on price and 572 reviews, and it still blunts.
Common questions
Is 18 mm or 9 mm the site size?
Eighteen millimetres is the snap-off width people use on plasterboard, flooring, and long scores. Nine millimetres is the narrower strip for paper, film, and detail. Sollex draws that split, and it is a maker’s guide rather than a British Standard. The Dekton in this set is 18 mm. A 9 mm knife is not one of the seven rows.
When do I need a hook blade instead of a straight one?
Use a hook when you are cutting carpet or a membrane and you do not want a straight tip to dig into the layer underneath. BuildWiz lists hook blades for that reason. This set does not print a hook blade as included, so check the photo before you assume one is in the Stanley box.
Does the knife store spare blades?
The Stanley listing says storage for 10 blades with magnetic retention, and it does not say 10 blades are supplied. The Edma says four in the compartment plus one fitted. The Dekton, Draper, yellow pair, and ceramic set do not state spare storage. Milwaukee reviews mention a spare in the handle, and those reviews are not marked United Kingdom.
Is a plastic snap-off enough for plasterboard?
An 18 mm snap-off is a reasonable width for scoring plasterboard. B&Q’s method is to score, snap the board, then cut the paper. The Dekton reviews also include a blade that slipped out of the back and knives that felt flimsy. Width and a body that holds the blade are separate questions. If the retainer fails, that knife is finished for the day.
Does a dearer knife remove the carrying rule?
No. Price does not change the offence of having a bladed article in a public place in England and Wales without a good reason. A folding knife that locks sits outside the small non-locking pocket-knife exception. Work can be a reason for that journey. The safety box cutter page is the short version, and it is not legal advice.
