How to Use a Mandoline Slicer Safely

A mandoline slicer is the fastest way to cut vegetables into uniform slices, julienne strips, and waffle cuts. What takes careful knife work — a potato into identical thin rounds for a gratin — takes a mandoline a few passes.

This is a research-based guide, not a hands-on test. Nora Whitfield's desk compared current Benriner, OXO, Kyocera, and de Buyer maker pages, published blade styles, and the listing mix-ups that waste a click: BN-64 is not Super Benriner, an OXO V-blade is not a straight Japanese slicer, and a ceramic Kyocera plank is not a steel Benriner. We did not run a cut-lab or score chips. This page stays on setup, gloves, and the identity you can verify before you order.

Desk take: Buy a Benriner plus a cut-resistant glove if you want a light Japanese ramp. Confirm BN-64 versus Super before you click. Buy an OXO V-blade if you want folding legs and a bigger guard. Skip a French stainless board if you will not store it. Volume shredding is a food processor. Garlic paste is a Microplane. Potato gratins still finish in essential bakeware.

What a listing will not tell you

Amazon tiles for "mandoline slicer" mix compact Benriners, wide Super Benriners, OXO V-blades, Kyocera ceramic planks, and French stainless boards with folding legs.

1. BN-64 is not Super Benriner. The classic compact Benriner (often sold as No. 64 / BN-64-class) is the narrower Japanese ramp most home cooks mean. Super Benriner is a wider platform for larger vegetables. They share the same brand word and a similar plastic-and-steel photo. Confirm width and the model name on the spec line.
2. OXO V-blade is not a Benriner. OXO Good Grips and Chef's Mandoline bodies use a V-shaped blade, rubber feet, and a larger hand guard. That is a different geometry from Benriner's straight single blade. Safer for beginners is not the same as thinner Japanese slices.
3. Kyocera ceramic is not a steel Benriner. Kyocera's adjustable ceramic slicer is a thin plank with a ceramic edge. It is not a Benriner replacement blade, and it is not a French stainless mandoline.
4. A hand guard in the photo is not a glove. Most boxes include a small pronged guard. Many cooks stop using it. A Level 5 cut-resistant glove is a separate SKU. Buy both.
5. Julienne inserts are not always in the box. Some Benriner listings include extra blades. Some are the slicer only. A waffle-cut hero shot is often a different Western body.

What is a mandoline slicer?

A mandoline is a flat platform with an adjustable blade mounted at an angle. You slide food across the blade, and the blade cuts uniform slices at the thickness you set. Most mandolines adjust from paper-thin (under 1mm) to about 6–8mm.

Beyond basic slicing, many mandolines include interchangeable blades for:

• Julienne cuts: Thin matchstick strips for stir-fries, salads, and garnishes
• Waffle cuts (crinkle cuts): Cross-hatched patterns created by rotating the food 90 degrees between each pass
• Fine and coarse shredding: For cabbage, carrots, and other vegetables

Uniform thickness means uniform cooking. Potato slices that are all the same thickness cook at the same rate.

Types of mandolines

Japanese-style (Benriner type)

A simple, lightweight rectangular slicer, typically plastic with a stainless steel blade. Japanese mandolines are compact, easy to clean, and sharp. They are the usual first buy because of that simplicity.

Pros: Lightweight, sharp, easy to store, compact, excellent for thin slicing. Cons: No folding legs on the compact body (you hold it at an angle over a bowl or board). The included guard is small.

Listing check: Confirm Benriner and whether the title says compact / BN-64 or Super. Skip no-name "Japanese mandoline" twins with a different blade width.

Skip this slicer if: you want self-standing legs and a large captive guard more than a light ramp.

French-style (Bron / de Buyer type)

A larger, heavier stainless steel slicer with folding legs that prop it over a container. French mandolines typically offer more blade options and a wider platform.

Pros: Stable, versatile, multiple blade options, built to last. Cons: Heavy, harder to store, more expensive, more parts to set up and clean.

Skip this slicer if: you wanted a drawer tool, not a counter appliance.

OXO / Progressive-style (handheld, V-blade)

Consumer-grade mandolines with built-in hand guards, rubber feet, and angled designs. These prioritize a larger guard and a self-standing stance. Blade feel is generally less precise on paper-thin cuts than a sharp Benriner.

Pros: Easier first use, self-standing, often dishwasher-safe parts (check the current page). Cons: Bulkier storage. V-blade and straight Japanese blade are not interchangeable.

Skip this slicer if: you already own a Benriner and a glove, and you only wanted thinner slices.

How to use a mandoline safely

Step 1: Set up your station

Place the mandoline at an angle over a cutting board or directly over a bowl or sheet pan to catch slices. If your mandoline has folding legs, extend them. If it does not (compact Benriner style), angle it against the back edge of your cutting board with the blade end resting on the board.

Make sure the mandoline is stable and will not slide. Place a damp towel under the cutting board if needed.

Step 2: Put on a cut-resistant glove

This is non-negotiable. Wear a cut-resistant glove on the hand that holds the food. A Level 5 glove is the single most important safety add-on when the included guard is awkward.

The hand guard that comes with most mandolines works, but it is clumsy with small or oddly shaped vegetables. A glove covers the whole hand, not just the palm.

Skip this glove if: you will only use a food-processor disc and will not own an exposed blade. If you own a mandoline, do not skip it.

Step 3: Set the thickness

Most mandolines have a dial or a knob that adjusts blade height. Start with a medium-thick setting to get comfortable with the motion, then go thinner.

For specific dishes:

• Chips and gratins: 2–3mm (thin but not transparent)
• General slicing: 3–4mm
• Thick rounds (for roasting): 5–6mm
• Paper-thin (carpaccio, garnishes): Under 1mm, which needs a sharp blade

Step 4: Slice with the right technique

Hold the food firmly with your gloved hand, fingers curled slightly (never flat). Apply gentle, even downward pressure as you slide the food across the blade in one smooth motion. Let the blade cut. You provide motion and light pressure.

Tempo matters. A steady, moderate pace produces the cleanest slices. Too fast and you risk slipping. Too slow and the food can catch on the blade and shatter.

Step 5: Know when to stop

When about an inch of food remains, stop. This is when most injuries happen. Use the hand guard for the last few slices, or save the end piece for stock.

Best foods for a mandoline

Potatoes: Uniform slices for gratin, scalloped potatoes, chips, and hasselback.

Onions: Rings and half-moons that cook evenly.

Cucumbers: Paper-thin slices for salads and quick pickles.

Radishes: Thin rounds for salads.

Cabbage: Fine shreds for slaw. A processor is faster for a whole head — see the food processor guide.

Zucchini and summer squash: Rounds or planks.

Fennel: Paper-thin shavings for raw salads.

Apples and pears: Thin slices for tarts and dehydrating.

Foods to avoid

Very soft tomatoes: They squish. Firm Romas can work; ripe slicers do not.

Very hard vegetables (raw beets, butternut squash): These need force, and force causes slips. Peel and halve first, or use a knife.

Very small items: Cherry tomatoes, garlic cloves, and shallots are too small to hold safely. For garlic or ginger paste, use a Microplane zester instead of putting fingertips near a mandoline blade.

Leafy greens: Too floppy. Use a knife.

Care and maintenance

Blade sharpness

A sharp mandoline blade is safer than a dull one: it cuts with less force, so you slip less. Some Japanese blades can be touched up on a fine stone if you already know how to sharpen knives. Many consumer blades are replace-not-sharpen. Check the maker page.

Cleaning

Wash immediately. Dried starch is harder to remove. Use a brush around the blade, not a sponge that can catch the edge. Most mandolines are hand-wash only; dishwashers dull the edge.

Storage

Store with the blade guard on. Keep it where nobody grabs blindly. Never toss a mandoline loose into a drawer with other tools.

Common mistakes

1. Not using a cut-resistant glove. The supplied hand guard is a minimum; a glove is the standard.
2. Slicing too small a piece. Stop at about an inch.
3. Using too much force. If you are pressing hard, the blade is dull or the food is too hard.
4. Slicing on an unstable surface. Damp towel, rubber feet, or a stable setup.
5. Trying to rush. Speed comes after the motion is boring.

Mandoline vs knife vs processor

A mandoline is better for many uniform slices and paper-thin cuts.

A knife is better for dice, mince, small quantities, and very hard vegetables. It does not replace basic knife skills.

A food processor is better for a pound of shreds. It will not give you the same paper-thin fennel sheet.

Final thoughts

A mandoline is a cheap, sharp ramp. The consistency it provides shows up in gratins, slaws, and pickles. Buy a named Benriner or a guarded V-blade, plus a glove. Use the glove every time. Stop before the food gets too small.
