Knives Task is reader-supported: if you buy through a link on this page, we may earn a small Amazon commission at no extra cost to you. That never changes which knives we recommend.
Carpet looks soft, but it’s tough on blades. The backing contains woven polypropylene or jute, and many carpets have a latex coating that dulls an edge quickly.
That’s why the knife matters less than you might expect, and the blade and technique matter more. A comfortable knife with quick blade changes, plus a stock of fresh blades, will out-cut an expensive knife with a dull edge.
Below are five tools that handle carpet and resilient flooring well, followed by a practical guide to cutting new carpet and removing old carpet.

How we chose: we haven’t lab-tested these knives side by side. We compared blade length and shape, steel, construction (forged or stamped), handle design and the makers’ published specifications, and we favored models with a long track record and consistent owner feedback over newer, unproven listings.
Features listed below come from the manufacturers’ product listings. Prices change often, so check before buying.
What to Look for in a Carpet Knife
Carpet installers use a small set of specialized tools, but a homeowner can do most jobs with a good utility knife and the right blades.
- Quick blade changes: you may change blades every few cuts, so tool-free changes save real time.
- Blade compatibility: a knife that takes standard and hook blades is far more versatile.
- Comfortable grip: long cuts and kneeling work strain your hand, so a full, grippy handle helps.
- Solid blade lock: carpet backing resists, and the blade must not slip back into the handle.
- Low profile: a slim nose lets you trim close to walls and under door trim.
The Best Utility Knives for Cutting Carpet
1. Craftsman Utility Knife for Carpet (CMHT10525) — Best Overall
Best for: homeowners laying or removing carpet in a few rooms.
Craftsman sells this knife specifically for carpet work, which is a good sign that the shape and blade setup suit the job. A knife designed for carpet is usually easier to guide along a straightedge and against a wall than a general box cutter.
Craftsman is a long-established American tool brand, and replacement blades are easy to find. Check the listing for the exact blade style it uses so you can stock up before you start.
For a weekend project, this knife plus a straightedge and a pack of blades is all most people need.
What we like:
- Designed for carpet
- Well-known tool brand
- Easy to buy replacement blades
What to consider:
- Less versatile than a general folding knife
- Confirm the blade type before ordering spares

2. Hook Utility Blades — Best Blade Upgrade
Best for: anyone cutting carpet from the back or trimming roofing and flooring.
A hook blade has its cutting edge inside a curved hook, rather than on the outside of a point. You slip the hook under the material and pull, so the edge cuts upward and the point never touches the floor beneath.
That makes hook blades ideal for cutting carpet and pad on top of finished floors, where a straight blade could score the wood or vinyl underneath. They also make quick work of cutting old carpet into strips for removal.
Hook blades fit most standard utility knives, so check that your knife accepts them. Buying a pack means you can change them as often as carpet demands.
What we like:
- Protects the floor underneath
- Fast, controlled pulling cuts
- Fits most standard knives
What to consider:
- Not for precise cuts from the face side
- Dull fairly quickly on latex-backed carpet

3. BIBURY Heavy-Duty Folding Utility Knife — Best Folding Option
Best for: DIYers who want one knife for carpet, packaging and general jobs.
BIBURY’s listing describes a heavy-duty folding box cutter with quick blade changes. A folding knife covers the blade when closed, which is handy when you’re moving between rooms and climbing over rolls of carpet.
It takes standard utility blades, so you can load a fresh straight blade for trimming or a hook blade for pulling cuts. For a home renovation, that flexibility is useful.
It’s not a specialist installer’s tool, but it’s a capable all-rounder at a modest price.
What we like:
- Folds closed for safe carry
- Quick blade changes
- Versatile for other jobs
What to consider:
- Folding hinge can collect carpet fibers
- Check the lock for any play before heavy use

4. Goldblatt and CHILI Tools Linoleum Knives — Best for Vinyl and Linoleum
Best for: trimming sheet vinyl, linoleum and some roofing materials, rather than thick carpet.
A linoleum knife has a curved, hooked blade fixed in a wooden or composite handle. You draw it toward you, and the hooked point slices through sheet flooring in one controlled pull.
Goldblatt describes its knife as a stainless steel roofing and flooring knife. The CHILI Tools linoleum knife uses SK-5 hardened carbon steel, according to its listing.
Linoleum knives aren’t the first choice for thick carpet, but if your project includes sheet vinyl in a kitchen or bathroom, they’re the right tool.
What we like:
- Excellent control on sheet flooring
- Simple, durable design
- Sharpenable fixed blade
What to consider:
- Not ideal for thick carpet
- Fixed blade needs a sheath or guard

5. MANUFORE 18mm Snap-Off Knife — Best for Underlay and Trimming
Best for: cutting foam underlay, carpet tape and thin materials.
Snap-off knives have long, segmented blades. When the tip dulls, you snap off one segment and have a fresh point in seconds.
That’s handy for foam padding and carpet tape, which need a sharp tip more than a heavy blade. MANUFORE’s listing describes a retractable 18mm knife with spare blades.
Snap-off blades flex more than standard utility blades, so don’t use one for heavy carpet backing. Use it as a second knife for lighter work.
What we like:
- Fresh tip in seconds
- Retractable blade
- Great for pad and tape
What to consider:
- Blade flexes under heavy pressure
- Not for thick carpet backing

Which Tool for Which Job?
| Job | Best tool | Tip |
|---|---|---|

| Trimming at the wall | Carpet knife or wall trimmer | Leave a little extra, then tuck |
| Removing old carpet | Hook blade | Cut into strips before rolling |
| Foam pad and tape | Snap-off knife | Keep the tip fresh |
| Sheet vinyl or linoleum | Linoleum knife | Pull the cut toward you |
How to Cut New Carpet Cleanly
Most tufted carpets are easiest to cut from the back, where you can see the rows and mark straight lines. Measure twice and leave a few inches of excess for trimming at the walls.
- Measure and mark: flip the carpet over and mark your line on the backing with chalk or a marker.
- Use a straightedge: lay a metal straightedge or carpet bar along the line and hold it firmly.
- Cut in one steady pass: keep even pressure so the blade cuts through the backing, not just the surface.
- Protect the floor: put scrap plywood or cardboard under the cut line if you’re using a straight blade.
- Change blades often: as soon as the cut starts to tear or fray, swap the blade.
Cutting Loop and Berber Carpet
Loop-pile carpets, such as Berber, can unravel if you cut through a loop. Installers usually cut them from the face, between rows, using a row cutter or a careful straight cut along the row.
Take your time with loop carpets. A crooked cut that slices loops is very visible once the carpet is laid.
How to Remove Old Carpet
Removing old carpet is mostly about cutting it into manageable pieces. A hook blade does this quickly and safely.
- Clear the room: remove furniture and take off any metal transition strips at doorways.
- Lift a corner: grab the carpet with pliers in a corner and pull it off the tack strip.
- Cut into strips: fold the carpet back and cut it into strips you can roll and carry easily.
- Roll and tape: roll each strip and tape it closed for disposal.
- Remove the pad: cut the pad into sections and pull out staples with pliers or a scraper.
Wear sturdy gloves and knee pads. Tack strips have sharp nails pointing up, and old carpet can be dusty, so a dust mask is a good idea.
Safety Tips for Carpet Work
Most carpet knife injuries happen when a blade slips during a hard pull. Good habits prevent most of them.
- Cut away from your body: keep your free hand behind the blade, never in front of it.
- Wear cut-resistant gloves: especially on the hand holding the straightedge.
- Use fresh blades: dull blades need more force and slip more often.
- Retract or close the knife: don’t leave an open blade on the floor, where you’ll kneel on it.
- Dispose of blades safely: drop used blades into a blade bank or a taped container.
Other Tools That Make Carpet Jobs Easier
- Metal straightedge: a 4-foot straightedge keeps long cuts true.
- Knee pads: carpet work is almost all done kneeling.
- Pliers and a flat pry bar: for lifting carpet, pulling staples and removing old tack strip.
- Chalk line or marker: for marking cut lines on the backing.
- Cut-resistant gloves: they protect against both blades and tack strip nails.
Blades: Buy More Than You Need
Professional installers go through blades quickly, and it’s normal to change blades many times in one room. A bulk pack is cheaper per blade and saves you a mid-project trip to the store.
