Best Mandoline Slicer 2026: 8 Compared
By KEOUKE Kitchen Team · Published · Updated
The best mandoline slicer for most cooks is the Super Benriner No. 95: America’s Test Kitchen’s Best Overall, Wirecutter’s top pick and Bon Appetit’s best overall, with a blade measured at 0.6 to 7.5 mm and replacements that cost less than half a new unit. If you want labeled settings and a guard that actually works, the OXO Chef’s Mandoline 2.0 is the easiest to use. Our own KEOUKE 6-blade handheld lands eighth as the budget multi-blade option.

This is the KEOUKE Kitchen Team’s ranking of mandoline slicers. We sell mandolines, so we read every spec sheet in this category for a living, and that is why we can tell you plainly that a Japanese blade from a company founded in 1934 beats ours for paper-thin slicing. We put every model on the same sheet, blade type, measured thickness range, extra cuts, guard design, dishwasher rules, weight and whether the blade can be replaced, then checked that sheet against seven independent test kitchens and the long-running Reddit threads where people report what a mandoline did to their fingers. No brand paid for placement.
How we ranked these slicers
A mandoline has one job: identical slices, faster and thinner than a knife. We weighted five things. Sharpness and evenness first, because a dull mandoline needs more pressure and, as Bon Appetit puts it, dull mandolines are the most dangerous ones. Measured thickness range second, using America’s Test Kitchen’s caliper figures where they exist and the maker’s claim where they do not, labeled as such. Guard and repairability third: whether the hand guard works, and whether you can buy a new blade instead of a new mandoline. Bulk and cleanup fourth. Price last: today’s Amazon price, shown in the comparison table above and refreshed daily, against what ships in the box. Price decides the value picks and breaks ties between mandolines that perform alike; it never lifts a mandoline that performs badly.
We did not invent test numbers. Where a lab measured something, we say which lab. Where a maker claims something no lab has checked, we say that too.
Four kinds of mandoline, and which one you actually need
Japanese flat mandolines (Benriner, Kyocera) are a single angled blade in a light plastic runway. They are the sharpest, cheapest to re-blade and the choice of nearly every professional. Their weakness is the pronged hand guard, which America’s Test Kitchen calls “pretty much useless” on the Benriner. Plan on a glove.
V-blade tabletop mandolines (Swissmar Borner, OXO V-Blade, Mueller Austria) meet the food with two blade edges. The pitch is less pressure on soft tomatoes. The evidence is mixed: America’s Test Kitchen’s guidance is to avoid V-slicers because the frame flexes at the V and food takes more force, and Wirecutter found no V-blade model that could slice a whole potato with every slice intact.
Enclosed-chute safety slicers (Dash Safe Slice, Cuisinart PrecisionSlice) put the blade inside a pump-action tower so your hand never approaches it. They are the right answer for a nervous cook or a grandparent who wants gratin without a trip to urgent care, at the cost of thinner and more even slices.
Chopper-mandoline hybrids (Fullstar Pro XL, Mueller Pro-Series, our own KEOUKE 12-in-1) are dicing grids with a slicing blade on top. They dice onions in one push and slice at one fixed thickness. They are not for potato chips, and only one test kitchen, The Spruce Eats, has ever put one in a mandoline roundup.
Why the test kitchens disagree
Seven publications have tested mandolines in the past three years and they do not agree, so we mapped the split rather than pretend it away.
| Publication | Best overall | Best for beginners or compact | Notable dissent |
|---|---|---|---|
| America’s Test Kitchen (2025) | Super Benriner No. 95 | OXO Chef’s 2.0 easiest to use; Kyocera Soft Grip best compact | Mueller and the older Swissmar V-1001 Not Recommended |
| Wirecutter (2025) | Super Benriner | Swissmar Borner VPower runner-up | ”We don’t recommend OXO mandolines,” including the handheld |
| Bon Appetit (2025) | Benriner Super Slicer | OXO Large Adjustable Handheld | Dash is “more of a guillotine”; Microplane deck dislodged |
| Epicurious (2025) | Benriner No. 64 for experienced cooks | Kyocera Soft Grip best for beginners; OXO Large Handheld most user-friendly | OXO Chef’s 2.0 blades “too dull”; Dash safest by a long shot |
| The Spruce Eats (2025) | Benriner Jumbo | Swissmar hand-held compact; OXO Chef’s 2.0 also picked | Kyocera “felt flimsy”; Dash chute too small |
| Consumer Reports (2023) | Super Benriner in top five | Kyocera, Dash, Borner V5, Mueller V-Pro in top five | ”Price isn’t a reliable indicator of a good mandoline” |
| Chris Loves Julia (2026) | Microplane V-Blade | Dash for safety | Benriner Super and OXO Chef’s units tested dull |
Two lessons come out of that table. First, the Benriner wins every professional test kitchen and loses only at a home-decor blog, and the likeliest explanation for a dull Benriner is unit variance and an old blade, which is exactly why a replaceable blade matters. Second, the OXO Chef’s 2.0 is the most polarizing model in the category: the easiest to use by the lab with calipers, and too dull by two others. We rank it second on the strength of its adjustment system and sharpenable blade, and we tell you the dissent.
The picks
1. Super Benriner No. 95: Best overall
The one mandoline the professional test kitchens agree on. America’s Test Kitchen named it Best Overall because “it had the sharpest blade we tested, slicing and making julienne from even the toughest foods as if they were butter,” and measured its range at 0.6 to 7.5 mm. Wirecutter found its blades “the sharpest, most durable, and most practical” of every mandoline it tested and notes that a replacement blade costs less than half a new unit. Bon Appetit called the blade “unmatched by any other adjustable mandoline.”

The runway is 14.2 by 5.9 inches, wide enough for a whole onion, and a non-skid rubber foot plus a notch let it rest on a bowl rim. Three julienne inserts snap in for matchsticks. What you give up is precision markings, since the dial is stepless with no numbers, and a hand guard that America’s Test Kitchen calls “pretty much useless.” Buy a cut-resistant glove with it and treat that as part of the price.
Pros:
- Sharpest blade in the America’s Test Kitchen, Wirecutter and Bon Appetit tests.
- Replaceable main blade and three julienne inserts.
- Light at 1.2 pounds, with a stepless dial from paper-thin to 7.5 mm.
Cons:
- The pronged hand guard is weak; a glove is not optional.
- No thickness markings, so repeat settings by feel.
- Bon Appetit: the plastic stains and it should be hand-washed despite the listing.
2. OXO Good Grips Chef’s Mandoline Slicer 2.0: Easiest to use and most adjustable
The mandoline for cooks who want a number. A dial gives 21 settings in 0.5 mm steps, America’s Test Kitchen measured 0.5 to 9.5 mm, and an indicator window shows the thickness in both inches and millimeters. The blade flips between straight and waffle, built-in julienne and French-fry blades swing into place, and the spring-loaded food holder has a wide rim that America’s Test Kitchen’s testers found genuinely protective. That lab named it Easiest to Use, and BBC Good Food called it the most versatile mandoline it tested.

The dissent is real. Epicurious found its blades “too dull,” and a home-decor blog’s unit was dull out of the box, while Wirecutter does not recommend OXO mandolines at all after testing the earlier SteeL version. America’s Test Kitchen’s own note is that it is “not quite as sharp as the Super Benriner, so it sometimes choked on fibrous produce.” The saving grace is that the slicer and waffle blades are removable and can be sharpened, and OXO backs it with a repair-or-replace guarantee. At 2.9 pounds it is also the heaviest tabletop here.
Pros:
- 21 labeled settings, 0.5 to 9.5 mm measured, plus waffle, julienne and fry cuts.
- The best hand guard of any conventional mandoline in the tests.
- Blades removable and sharpenable; OXO Better Guarantee.
Cons:
- Less sharp than the Benriner; two publications found their units dull.
- Heavy and bulky at 2.9 pounds and 17.6 inches long.
- Hand-wash recommended, and the spring pusher tires arms on long jobs.
3. Benriner Japanese Mandoline Slicer No. 64: Best compact Japanese mandoline
The original Benriner, named for its 64 mm runway, and Epicurious’s pick for experienced cooks. It shares the Super’s ultrasharp blade and stepless dial in a body that is 12.75 inches long and weighs 15 ounces, and it comes apart completely, which Epicurious found made it the easiest mandoline to clean. Blades are replaceable, and the same three julienne inserts are included. America’s Test Kitchen rates it Highly Recommended, a notch below the Super only because the 2.5-inch-wide platform limits you to produce you can hold in one hand.

If your mandoline work is radishes, cucumbers, shallots and garlic rather than whole sweet potatoes, this is the better buy and the smaller footprint.
Pros:
- Same blade quality as the Super in a drawer-sized body.
- Fully disassembles for cleaning; replaceable blade.
- Stepless dial from half a millimeter to 8 mm by Benriner’s figures.
Cons:
- 2.5-inch runway rules out large produce.
- America’s Test Kitchen: it “lacks a functional hand guard.”
- No thickness markings.
4. OXO Good Grips Large Adjustable Handheld Mandoline: Best for beginners
Bon Appetit’s and Epicurious’s pick for first-time mandoline owners, and for good reason. Clearly labeled settings in 0.5 mm steps, a see-through slicing plane so you can watch the blade, an oversized food holder that actually holds, and a blade that locks for storage. It is dishwasher safe and light enough to hold over a bowl with one hand. Bon Appetit’s one wish is that the blade were “just a hair sharper,” and Epicurious found each step “a pretty big jump.” OXO’s listing lists three thicknesses while both test kitchens counted seven labeled settings on their units, so check the dial on yours.

Pros:
- Labeled settings and a transparent runway make it the most forgiving mandoline to learn on.
- A hand guard that works, dishwasher safe, no assembly.
- Bon Appetit and Epicurious beginner pick.
Cons:
- Not as sharp as the Benriner or Kyocera.
- No julienne; blade is not replaceable.
- Slices only; no waffle or crinkle.
5. KYOCERA Adjustable Ceramic Mandoline Soft Grip: Best compact
The 7-ounce handheld that America’s Test Kitchen named Best Compact, Epicurious called the best mandoline for beginners, and Consumer Reports put in its top five. Its zirconia ceramic blade does not rust and, in Epicurious’s experience, “stays sharp for years.” Four fixed settings cover 0.5, 1.3, 2 and 3 mm by Kyocera’s figures, which America’s Test Kitchen measured at 0.7 to 2.5 mm, and corner notches hook over a bowl.

It is a thin-slice specialist and nothing else. It cannot julienne, it is too narrow for a large potato, the blade cannot be replaced, and its hand guard is, in America’s Test Kitchen’s word, “useless.” Wirecutter found the body flexed under pressure, and The Spruce Eats dropped it as flimsy. For cucumbers, radishes, shallots and fennel it is superb; for gratin potatoes, look elsewhere.
Pros:
- Ceramic blade holds its edge for years and never rusts.
- Lightest model here at 7 ounces; dishwasher safe.
- Best Compact at America’s Test Kitchen and a Consumer Reports top five.
Cons:
- Maximum 3 mm and no julienne.
- Guard useless; glove required.
- Fixed, non-replaceable blade and a body that flexes.
6. Swissmar Borner VPower V-Slicer: Best V-blade
If you want a V-blade, this is the one two labs endorse: Wirecutter’s runner-up, which found it “sharp right out of the box,” and a Consumer Reports top-five pick in its V5 PowerLine version. Thickness changes with a push button, no insert swapping, and the 3.5 mm and 7 mm inserts add julienne, shreds and even cubes. It is made in Germany, weighs only 8 ounces, ships with a pronged safety holder plus a plunger that works, and carries a two-year limited warranty.

The V-blade costs it. Wirecutter reported it “left both potatoes and sweet potatoes mangled,” the blade cannot be replaced, and Bon Appetit and Epicurious both found the whole setup awkward. America’s Test Kitchen rated the older V-1001 version Not Recommended.
Pros:
- Sharp out of the box; push-button thickness with no blade swaps.
- Safety holder and plunger that keep fingers clear.
- Made in Germany, 8 ounces, two-year warranty.
Cons:
- V-blade mangled potatoes in Wirecutter’s test.
- Blade is not replaceable.
- Only two straight-slice thicknesses without inserts.
7. Dash Safe Slice Mandoline: Safest design
For anyone whose main worry is their fingertips. The blade sits inside an enclosed tower; you load the chute, pump the handle, and the food comes out sliced, diced or in matchsticks without your hand ever approaching an edge. Epicurious called it “the safest mandoline we tested by a long shot,” America’s Test Kitchen rates it Recommended and confirms it is “as safe as advertised,” and Consumer Reports placed it in its top five. Dash lists a 1 to 8 mm dial with more than 30 cutting combinations; America’s Test Kitchen measured nine settings from 1.6 to 8.2 mm. It folds, includes a catch container and cleaning brush, is dishwasher safe, and Dash publishes a one-year warranty, two with registration.

The compromise is cut quality. America’s Test Kitchen found it “doesn’t cut as thinly, consistently, or evenly as we’d prefer,” Bon Appetit called it “more of a guillotine than a mandoline” that cuts on a bias, and The Spruce Eats found the chute too small for large produce.
Pros:
- The only design here where fingers physically cannot reach the blade.
- Slices, dices and juliennes; folds flat; dishwasher safe with brush.
- Published one-year warranty.
Cons:
- Thinnest measured setting is 1.6 mm; slices are less even.
- Chute limits produce size.
- Cuts on a slight bias.
8. KEOUKE Transparent Multifunctional Mandoline Slicer, 6 blades: Budget multi-blade handheld
Our own handheld, placed last on purpose. No independent lab has tested it, and we are not going to rank an untested tool above ones that have been through seven test kitchens. What it is: a clear polypropylene handheld with six swap-in stainless inserts, thick slice, thin slice, crinkle, coarse shred, fine julienne and a garlic grater, a finger protector that grips the food, and parts that all come apart and go in the dishwasher. At 11.6 inches it holds over a bowl one-handed, and it does in one tool what the Kyocera plus a box grater do in two.

What it is not: a paper-thin slicer. Each insert has one fixed thickness, we do not publish millimeter figures for them, there is no stepless dial, and the blades are not sold as replacements. If you mostly need a crinkle-cut cucumber, shredded carrot for slaw and a few even potato rounds, it earns its counter space. If you want chips you can read a newspaper through, buy the Benriner. Our how to use a mandoline slicer guide applies to it as much as to any model here.
Pros:
- Six cutting styles in one handheld, including crinkle and shred.
- A finger guard that stays on the food, and every part dishwasher safe.
- Clear body shows the slices stacking up.
Cons:
- Untested by any lab; no published thickness figures.
- Fixed thickness per insert, no fine adjustment.
- Plastic body; inserts not sold separately.
Also considered
- Mueller Austria 5-Blade. A Consumer Reports top-five pick and a bestseller, but America’s Test Kitchen rates it Not Recommended for slices “that mimicked its blade’s V-shape,” and Bon Appetit and Epicurious both hit the 1 mm floor and could not get chips thin enough.
- Fullstar Pro XL Chopper and Mandoline. The Spruce Eats’ hybrid pick, and it ships a cut-resistant glove. A dicer first and a slicer second, at a fixed 2 mm.
- Microplane Adjustable V-Blade. A home-decor blog’s best overall, but Bon Appetit and Epicurious both had the reversible julienne deck dislodge mid-slice, and Bon Appetit called it “duller than the competition and potentially dangerous.”
- de Buyer Kobra and Revolution. French stainless. America’s Test Kitchen rates the Revolution Recommended with a 2 to 15 mm range but notes it cannot slice paper-thin; Wirecutter found the Kobra’s micro-serrations “hindered rather than helped.”
- Gramercy Kitchen Co. Twelve settings and a glove in the box, but Epicurious found it “didn’t outperform” cheaper models.
- Bron Coucke. The Spruce Eats’ professional pick, five pounds of stainless and a metal-on-metal scrape. Restaurant gear.
- OXO Good Grips V-Blade. Serious Eats’ pick for most people by its published summary; Wirecutter does not recommend it. The listing was on pre-order when we checked, so we did not rank it.
Which mandoline for which job?
| Job | Thickness you need | Best tool here |
|---|---|---|
| Potato or beet chips | Under 1 mm | Super Benriner, Kyocera |
| Gratin and scalloped potatoes | 2 to 3 mm | OXO Chef’s 2.0, Benriner No. 64 |
| Cucumber and radish salad | 1 to 2 mm | Kyocera, OXO Large Handheld |
| Slaw and shaved fennel | Paper-thin | Super Benriner |
| Julienne and matchsticks | 2 to 4 mm | Super Benriner with insert, OXO Chef’s 2.0 |
| Waffle and crinkle cuts | 4 mm and up | OXO Chef’s 2.0, KEOUKE 6-blade |
| Dicing onions and peppers | Grid | A chopper-hybrid, not a mandoline |
What long-term owners say
We pulled 489 comments and 481 posts about mandolines from r/Cooking, r/Chefit, r/KitchenConfidential, r/cookingforbeginners, r/BuyItForLife and r/AskCulinary through the Arctic Shift archive. Three things stand out. Benriner is named in 150 of those comments across 97 threads, more than every other brand combined; the typical line, from an r/Cooking thread on good mandolines, is “Benriner is industry standard in professional kitchens. Sharp as hell and built to last. Just use the guard or get a cut glove.” Gloves come up in 131 comments across 47 threads and the advice is nearly unanimous: the top reply in the r/Cooking thread that ranks on Google for this query is simply “Be sure to get a Kevlar glove. You’ll thank me later.” And 68 comments across 50 threads are first-person fingertip injury stories, most of them ending with “I was almost done.” No KEOUKE mandoline is mentioned anywhere in that corpus, which is one more reason we rank ours last.
Mandoline safety, with the numbers
A mandoline is the most finger-hostile tool in a home kitchen, and the data says so. A kitchen injury audit of federal NEISS data published at cambom.org estimates roughly 16,800 US emergency-department visits a year from mandolines across 2023 to 2025, up 84 percent over three years, with 35 percent of those injuries recorded as avulsions, tissue removed rather than cut, against 3 percent for knives. Knives cause far more injuries in total, about 434,000 emergency visits a year in a 2013 study in the Journal of Emergency Medicine, but they rarely take the fingertip with them.
Four habits eliminate almost all of the risk:
- Wear a cut-resistant glove. ANSI/ISEA 105 grades cut resistance from A1 to A9; A5 withstands 2,200 to 2,999 grams of force and is the level trade guidance suggests for mandolines and graters. America’s Test Kitchen’s glove test found the number matters less than fit: A3 to A7 gloves performed alike, and loose fabric at the fingertips caught on blades. Gloves are cut-resistant, not cut-proof, and not puncture-resistant.
- Use the guard when it works. The OXO holders, the Borner plunger and the Dash chute earn their keep. The Benriner and Kyocera prongs do not, which is why the chefs Wirecutter interviewed skip them and wear gloves.
- Stop at the last inch. Every avulsion story on Reddit starts with “I was almost done.” Finish the nub with a knife.
- Keep the blade sharp. A dull blade needs pressure, and pressure is what sends a hand past the edge. Replace or sharpen, and never run a blade through the dishwasher.
Care and cleaning
America’s Test Kitchen’s rule: any part with a blade gets hand-washed. Rinse immediately so starch does not dry on the edge, brush from the back of the blade, and dry before storage. OXO’s handhelds, the Kyocera and the Dash are labeled dishwasher safe; the Benriner listing says top rack, but Bon Appetit found the plastic stained and recommends the sink. Store tabletop models with the blade set to zero or the guard in its storage slot. On a Benriner, budget for a new blade every couple of years of heavy use; Epicurious’s rule is to replace it “as soon as it starts snagging.”
For a second opinion built on the same test kitchens, the best mandoline slicer comparison at cambom.org ranks five models with a focus on the Japanese and V-blade divide.

Frequently Asked Questions
What is the best mandoline slicer?
The Super Benriner No. 95 is the best mandoline for most cooks who want paper-thin, even slices. America's Test Kitchen named it Best Overall with the sharpest blade it tested and a measured range of 0.6 to 7.5 mm, Wirecutter has made it its top pick, and Bon Appetit says its blade was unmatched. If you want clearly labeled settings and the best food holder, the OXO Chef's Mandoline 2.0 is the easiest to use. Pair either with a cut-resistant glove.
What mandoline do professional chefs use?
A Japanese flat mandoline, almost always a Benriner. Bon Appetit writes that you would have to search high and low to find a culinary professional who recommends anything else, and every chef Wirecutter interviewed used a Japanese mandoline. Professionals mostly skip the included hand guard and wear a cut-resistant glove instead.
Is a mandoline really that dangerous?
It is the kitchen tool most likely to take a piece of fingertip. A federal injury-data audit published at cambom.org estimates roughly 16,800 US emergency visits a year from mandolines, with about 35 percent of those injuries being avulsions, meaning tissue removed, compared with 3 percent for knives. Nearly all are treated and released. The fix is simple: use the guard or a cut-resistant glove, and never slice the last inch of a vegetable by hand.
Do I need a cut-resistant glove for a mandoline, and what level?
Yes, especially with the Benriner and Kyocera, whose hand guards every test kitchen calls weak. ANSI/ISEA 105 rates cut resistance from A1 to A9; A5 gloves withstand 2,200 to 2,999 grams of cutting force and are the level industry guidance suggests for mandoline work. America's Test Kitchen found that fit matters more than the number: gloves rated A3 to A7 performed the same on kitchen tasks, and loose finger fabric caught on blades.
How thin can a mandoline slice?
The top models slice from about half a millimeter. America's Test Kitchen measured the Super Benriner at 0.6 mm minimum and the OXO Chef's 2.0 at 0.5 mm. The Kyocera's thinnest fixed setting is 0.5 mm. Budget multi-blade sets such as the Mueller Austria bottom out at 1 mm, which Bon Appetit and Epicurious both found too thick for potato chips.
V-blade or straight blade mandoline?
Straight, for most cooks. America's Test Kitchen advises avoiding V-slicers because food meets two blades at once, takes more force, and the V-frame has little support at its center. Wirecutter found no V-blade mandoline could slice a whole potato while keeping every slice intact. The one argument for a V-blade is soft produce: The Spruce Eats found it gives an edge on tomatoes.
Japanese or French mandoline?
Japanese for almost everyone. The Benriner style is light, sharp, stepless and cheap to re-blade, and Wirecutter notes it has been the chefs' preferred type for two decades. French stainless models such as the de Buyer Revolution or Bron Coucke weigh 3 to 5 pounds, cost several times more, and Wirecutter says they take longer to set up than to slice with. They earn their place only in a restaurant that slices by the case.
Can you replace or sharpen a mandoline blade?
On some. The Super Benriner and Benriner No. 64 have removable blades that Benriner sells separately for less than half the price of a new mandoline, and America's Test Kitchen notes the Super Benriner and OXO Chef's 2.0 blades can be removed and sharpened. Kyocera ceramic, Microplane, Swissmar Borner and most handheld blades are fixed. Epicurious suggests replacing a blade as soon as it starts snagging.
Are mandolines dishwasher safe?
Bodies often are, blades rarely should be. America's Test Kitchen's rule is that any component with a blade must be hand-washed. OXO labels its handheld slicers dishwasher safe, the Kyocera listing says dishwasher safe, and Dash includes a cleaning brush and calls its unit dishwasher safe. The Benriner listing says top-rack safe but Bon Appetit found the plastic stains and recommends hand washing.
Which mandoline is safest for a beginner or an older cook?
The Dash Safe Slice, whose enclosed pump chute keeps fingers away from the blade entirely; Epicurious called it the safest mandoline it tested by a long shot and America's Test Kitchen rates it Recommended. The trade-off is thinner-and-even slicing, where it lags. For a conventional mandoline with a guard that works, Bon Appetit and Epicurious both point beginners to the OXO Large Adjustable Handheld.
The KEOUKE 6-blade handheld slicer
Six swap-in stainless inserts, a finger guard that stays on the food, and every part dishwasher safe.
