The best utility knives, compared.
Top pick: Edma 170155 double-system cutter Best value: Draper 90503 safety packaging cutter – Lowest price in the set, about £2.99, with the largest star line: 4.3 from 572 reviews. Updated 22.10.2026.
A utility knife in UK DIY and trade use is a hand cutter for packaging, plasterboard, insulation, flooring and similar sheet work. It is not a kitchen knife and not a pocket multi-tool. You buy one as a householder opening parcels, as a DIYer scoring boards, or as a trade who wants a blade that can be renewed before the cut starts to tear. A suitable knife keeps the blade seated, lets you renew the edge quickly, and has a body you are not tempted to pry with. The four types that matter are the trapezoid retractable or trade knife, the 18 mm snap-off, the folding one-handed site knife, and the shielded safety cutter. Tell them apart by the job first: tape and film, long scoring, carpet and membrane, or a knife that also carries a driver. At work, keep spares so a dull edge is not the one in the hand, and keep the blade out to the minimum that still cuts. How to match the type to the job is set out in our [utility knife buying guide](/hub/hand-tools/utility-knife/sub/utility-knife-buying-guide).

Personal buying guide
Question 1 of 2
What are you cutting most?
The Edma 170155 is a French-made cutter at about £12.51, listed at 240 g, with a soft-touch handle, an integrated wire cutter, and a compartment for four spare blades plus one fitted. The star line is 5.0 from a single amazon.co.uk review, and the scaled score is 80, which is a thin sample next to the parcel cutters here. That review says the buyer is very happy and names no job and no fault. Blade width, blade steel, and whether the blade retracts are not on the listing, and a safety lock is asked and not answered. The rank sits under Shears and scissors rather than Utility knives. Buy it if you specifically want the onboard wire cutter and the spare-blade compartment, and treat the five stars as one person's note.
Pros
Cons
Best for: You want a cutter that holds spare blades and cuts wire, and you can accept a one-review file.
Less suitable: You want UK review comments on cardboard, carpet, or a named lock.
Specifications
Common questions
Does the Edma cutter hold spare blades?
The listing says a compartment for 4 blades plus 1 blade in the cutter, and a quick blade-change system.
Does it have a safety lock?
A safety lock is asked on the listing and not answered. No lock type is given.
What else can it cut besides sheet?
An integrated wire cutter is listed. The question about materials is not answered as a spec. There is one review, and it gives no detail.
The Milwaukee Fastback 48-22-1505D is a 2-pack of folding 6-in-1 knives at about £40.90, listed at 290 g and 6 inches, with a thermoplastic rubber handle. The bullets name a press-and-flip opening, a wire stripper, and a folding screwdriver with a 1/4 inch bit holder. The star line is 4.8 from 174 reviews, and the scaled score is 88, the highest in this set, so it is the top pick on that score. None of the 44 review texts in the capture is marked as reviewed in the United Kingdom. Those reviews praise the flip opening, the bit holder, and daily drywall and roof work, and they also describe a blade that can feel loose when the knife is folded, a bit-holder ball that fell out, and more than one 2-pack that arrived as a single knife. A lock button is not named on the listing. It is the top pick only if you want two folding site knives with a stripper and a driver, and the missing UK review marks are the reason not to treat the 4.8 as British site opinion.
Pros
Cons
Best for: You want two folding site knives with a wire stripper and a bit holder, and you can live with reviews that are not UK-marked.
Less suitable: You only open parcels, or you need written UK reviews before you spend about £40.90.
Specifications
Common questions
What tools are built in?
The bullets name a press-and-flip opening, a wire stripper for electrical prep, and a folding screwdriver with a 1/4 inch bit holder.
Is this sold as a pair?
The title and the included-components line say a 2-pack. More than one review says only one knife arrived. One review says blades were not included.
Are the written reviews from the UK?
The star line, 4.8 from 174, is the amazon.co.uk listing. None of the 44 review texts in the saved listing is marked as reviewed in the United Kingdom.
The Dekton DT60126 is a three-knife 18 mm snap-off set at about £7.13, listed at 100 g, with a pack size of 2.46 × 15.4 × 21.5 cm. Across 168 amazon.co.uk reviews the line is 4.5, and the scaled score is 83. Reviewers use the knives on parcels, tape, wallpaper, PIR foam, and warehouse boxes, and one buyer was still on the first segment after ordinary parcel cutting. The same file keeps returning to a plastic body that feels flimsy, a retract that can take more than one attempt, and edges that blunt quickly. One buyer said the blade slipped out of the back twice and the rear retainer came loose, and another said all three knives broke before use. Blade steel and the lock type are not on the listing. It is a cheap way to keep three 18 mm knives for light cutting, and a poor bet if the blade has to stay seated under a hard push.
Pros
Cons
Best for: You want three cheap 18 mm knives for parcels, wallpaper, and light DIY.
Less suitable: You need a blade that stays seated, or a stiff trade knife for carpet and flooring.
Specifications
Common questions
Are the Dekton blades 18 mm?
Yes. The listing says 18 mm retractable snap-off blades. It does not name the blade steel.
Will this set cut heavy plastic?
The listing asks about plastic and does not answer it as a spec. One review says the knives are for small use only, not heavy plastic.
Is there a blade cover?
A cover is asked and not answered. The title says the blades retract. Reviews describe the retract as awkward, and one says the blade slipped out of the back.
The Stanley FatMax FMHT10501-0 is a heavy-duty trade knife at about £17.52, listed at 182 g and 6 inches, with an alloy-steel blade and a hardened-steel holder. The bullets name carpet fitting, flooring, and drywall, and the handle stores 10 blades with magnetic retention. Blade changes use a coarse-threaded thumb wheel, and the listing does not mention a screwdriver. The star line is 4.5 from 19 reviews, and the scaled score is 78. Only one of the three reviews in the file is marked United Kingdom, and it praises the magnet hold and ease of use without naming a fault. A French review, which is not UK opinion, calls it comfortable in the hand and on a belt. Whether the blade retracts, and whether spare blades are in the box, are not stated. It is the trade knife in this set for flooring and board, with a review file that is still short.
Pros
Cons
Best for: You cut carpet, flooring, or drywall and want spare blades in the handle.
Less suitable: You want a long UK review file, or a knife the listing says retracts.
Specifications
Common questions
What does Stanley say this knife is for?
The bullets name carpet fitting, flooring, drywall, and other tough professional cutting. It is ranked 19 in Carpet knives.
How do you change the blade?
A coarse-threaded quick-release thumb wheel. The listing does not mention a screwdriver.
How many blades fit in the handle?
Integral storage for 10 blades with magnetic retention. Whether 10 blades are in the box is not stated. The only UK review praises the magnet hold.
The Draper 90503 is a shielded packaging cutter at about £2.99, with a plastic body, an alloy-steel blade, and a listed length of 3 inches. Across 572 amazon.co.uk reviews the line is 4.3, and the scaled score is 83. Reviewers use the hook and the short blade on tape, film, strapping, feed sacks, and bale string, and some report months of daily use. The same file says the main blade blunts quickly, that the front groove can be too short for shrink wrap, and that two buyers found the thumb slide easier with a right hand. One review says the blades cannot be replaced, and another unit arrived with the retractable blade missing. The listing weight of 600 g conflicts with reviews that call the same cutter light and pocket-sized. It is the best value here for tape and film, and a weak choice if you need a fresh edge on thick board all afternoon.
Pros
Cons
Best for: You open tape, film, and parcels and want the cheapest well-reviewed shielded cutter in this set.
Less suitable: You are left-handed and need a stated left-hand slide, or you cut thick board all day.
Specifications
Common questions
Is the Draper blade shielded?
The listing calls it a safety-style packaging cutter with a soft grip and a shielded blade, for packaging, strapping, film, and boxes.
Can you replace the blade?
The listing does not describe a blade change. One review says you cannot replace the blades. Another says the retractable blade was missing on arrival.
Does it suit a left hand?
The listing does not say. Two reviews say the thumb slide is easier for a right hand.
The TNCIAD PW yellow pair is two concealed-blade box cutters at about £5.99, listed at 40 g, with a stainless blade and a non-retractable handle type. The star line is 4.3 from 256 amazon.co.uk reviews, and the scaled score is 81. Buyers use them on tape, cling film, bubble wrap, and thinner card, and some keep one in a pocket or on a lanyard. The same reviews say the edge dies after a few cuts, that thick fibreboard is a common failure, and that starting a cut is harder than with an open blade. Blade change and spare storage are not on the listing, and the reviews read do not describe a replacement blade. A safety lock is asked and not answered. The pair is a cheap parcel opener, and it is the wrong tool when you have to break thick cartons down.
Pros
Cons
Best for: You open parcels, film, and thin card and want a concealed edge in a pocket.
Less suitable: You break down thick cartons or you need a blade you can replace.
Specifications
Common questions
Is the blade hidden?
The listing says a concealed blade. The handle type is non-retractable. A safety lock is asked and not answered.
Will the pair cut thick cardboard?
Thick cardboard is asked and not answered as a spec. The bullets name bubble wrap, stretch film, foam, and polyethylene. Reviews often say thick fibreboard is where they fail, and that the edge dulls quickly.
Can you change the blade?
Blade change and spare storage are not on the listing, and the reviews read do not describe a replacement blade.
The Reyuvidep set is three ceramic package cutters at about £4.29, listed at 30 g, in black, pink, and white, each with a keychain hole. The star line is 4.0 from 8 reviews, and the scaled score is 69, the lowest here because the sample is small. Three short reviews say the cutters cut boxes, feel slightly textured, and seem sturdy, and none of them names a fault. The bullets claim boxes, letters, and plastic packaging, and they call the cutter safe, without naming a standard. Whether the ceramic edge retracts or sits concealed is not on the listing, and cardboard is asked as a question and not answered as a spec. Blade change is not described. Treat it as a light keyring opener for letters and thin packaging, not as a site knife for plasterboard or carpet.
Pros
Cons
Best for: You want a light keyring cutter for letters and thin packaging.
Less suitable: You need a site knife for plasterboard, carpet, or a replaceable steel blade.
Specifications
Common questions
What is the blade made of?
Ceramic. The handle and body materials are listed as plastic.
Can you put it on a keyring?
The bullets include a keychain hole for keys, a bag, or a backpack.
Does it cut cardboard?
Cardboard is asked and not answered as a spec. The bullets name boxes, letters, and plastic packaging. One of the three reviews says it cuts boxes. No review names a fault.
Seven amazon.co.uk utility-knife listings are scored from the snapshot saved with this set. The score is the star rating times 16, plus a review-count weight of up to 15, using round(stars × 16 + min(15, log10(review count) × 5)). Stars can contribute up to 80. That block is the whole numeric score. Equipment, price and sentiment are used in the written assessment and in the badge choice. They are not a second hidden total. This is not a lab test, not a Which? award, and not a measured cut. A one-review file, a weight that conflicts with the reviews, or written reviews that are not marked United Kingdom changes how the row is read. The top pick is the highest scaled score. Best value is the shielded cutter with a large star line at the lowest price in this set. Neither badge means the best utility knife on amazon.co.uk.

Start with the job, then the way the edge is renewed. Householders opening parcels want a shielded cutter. DIYers scoring plasterboard or insulation want an 18 mm snap-off and somewhere to put the segments. Trades and warehouses want a specified knife, spares, and a carrying rule for the journey to site. Price comes after the type. A low price that will not open thick board is the wrong tool. The notes below are taken from public UK sources and the amazon.co.uk listings in this set.
A utility knife in UK DIY and trade use is a hand cutter for packaging, plasterboard, insulation, flooring and similar sheet work. It is not a kitchen knife and not a pocket multi-tool. Shoppers are householders opening parcels, DIYers scoring boards, and trades who want a blade they can renew before the cut starts to tear. Quality shows up as a blade that stays seated, a way to renew the edge quickly, and a body you are not tempted to pry with.
A utility knife is for packaging, plasterboard, insulation, flooring and similar sheet work. A kitchen knife or a sharpener is the wrong tool, and it does not give you a renewable site blade.
The body is not a pry bar. Twisting a long snap-off is how the segment breaks and the blade can leave the retainer. Use the minimum blade out, and renew the edge before you start pushing harder.
Do not bin loose segments. Westminster City Council asks for a rigid box marked SHARP ITEMS, or a blade case for small blades, then general waste. Other councils differ. A locking knife in public still needs a good reason.
Job and blade come first. A trapezoid is for plasterboard, PIR and sheet. A hook or concave edge is for carpet, felt and membrane. An 18 mm snap-off is for a fresh tip often. A concealed edge is for tape and thin card. A ceramic keyring cutter is only a parcel tool. A folding one-handed site knife is the type that also carries a driver. Match the knife to that job before you look at price. A cheap cutter that will not open thick board is the wrong tool.
How the edge is renewed, and whether it stays put, is the next check. A tool-free change or a snap beats a screw-open body for daily use. That is a trade-guide point, not a lab score. The Health and Safety Executive says spares must be available so people stop using a dull edge. Look for a lock, a retainer or a shielded throat. Cheap snap-off reviews in this set describe a blade slipping out of the back. Keep the minimum blade out. At work, use the specified knife.
Three typical situations, each with a recommendation from this comparison.
You want a shielded cutter for tape, film and thin card. The Draper 90503 is the best value here, at about £2.99, with 4.3 from 572 reviews. Blade replacement is not listed, and two reviews say the thumb slide suits a right hand.
You are scoring plasterboard, wallpaper or light insulation and you want three 18 mm snap-off knives. Reviews describe a blade slipping out of the back, so this is a light-duty set, not a stiff trade knife for carpet.
You need a specified knife for carpet, flooring or drywall, with spare blades in the handle. The Stanley FatMax stores 10. The listing does not say the blade retracts. A locking knife on the way to site still needs a good reason.
The top pick is the Milwaukee Fastback 48-22-1505D, sold as a 2-pack at about £40.90. The scaled score is 88, from 4.8 and 174 reviews, the highest in this set. None of the 44 review texts in the capture is marked United Kingdom. It is a folding knife with a wire stripper and a 1/4 inch bit holder, not a parcel cutter. The best value is the Draper 90503 at about £2.99, score 83 from 4.3 and 572 reviews. It is the lowest price in the set, with the largest star line. The Dekton snap-off set also scores 83, at about £7.13 from 168 reviews, so it does not take the best value place. The listing weight of 600 g on the Draper conflicts with reviews that call it light.
