Best Mandoline Slicers: Tested for Precision and Safety
A mandoline is the fastest way to get restaurant-thin, perfectly even slices at home — and the fastest way to nick a fingertip if you get careless with it. I’ve kept one in my Portland kitchen for years, and after putting five current models through the same potato, cucumber, and carrot tests, I have strong opinions about which ones slice cleanly and which ones actually keep your hands safe.

This is a precision-and-safety roundup, not a spec sheet. I cared about two things above all: how thin and consistent the slices came out, and how confidently I could use the thing without watching my knuckles the whole time. Here are my picks, organized by what you actually need.
My quick picks at a glance
- Best overall / most adjustable: OXO Good Grips Chef’s Mandoline Slicer 2.0
- Best for precision: Benriner Super Slicer (Japanese blades)
- Best value (gloves included): Gramercy Adjustable Mandoline
- Best for safety: ONCE FOR ALL Safe Mandoline Slicer Plus
- Best for cleanup & storage: Fullstar All-in-One
If a mandoline feels like overkill, it’s worth remembering how much hand-slicing it replaces — it earned its drawer space faster than most tools in my guide to kitchen gadgets that are actually worth buying.
How I tested
Every slicer ran the same gauntlet: a waxy potato (the classic test for even, paper-thin rounds), a cucumber (soft skin that tears on a dull or wobbly blade), and a carrot (dense, the one that exposes flimsy frames). I judged precision by stacking ten slices and checking how level the pile sat — uneven slices fan out and lean. For safety, I looked at the hand guard’s grip, whether the blade locked at a defined thickness, and how exposed the blade stayed during storage. I also timed setup and cleanup, because a mandoline you dread washing is a mandoline you stop using — the opposite of the time-savers in my gadgets that actually save time roundup.
OXO Good Grips Chef’s Mandoline Slicer 2.0 — Most Adjustable
This is the one I reach for when slice quality matters more than anything. A dial steps you through 21 thickness settings, and the change is genuinely fine-grained — I could go from translucent potato chips to a sturdy gratin slice without guessing. The straight blade tracked dead-level through all three test foods, and the fold-flat legs and angled body make it the most comfortable to use of the group. The runner-up wins here too: it doubles as a julienne and crinkle cutter without separate inserts to lose.
The con: it’s easily the priciest pick, and the bulky body eats more drawer space than a folding model. The food holder also grips small or round items (a shallot, a lime) less securely than I’d like — I finish those by hand. If precision is your priority and budget isn’t, though, nothing else here matched its consistency.
Benriner Super Slicer — Best for Precision
The Benriner is the slicer a lot of professional kitchens quietly rely on, and after using one I understand why. The Japanese stainless blade is scary sharp out of the box, and it’s the only model here that gave me truly translucent cucumber without dragging or tearing the skin. It comes with four blades (flat plus three julienne widths) and a screw on the underside to micro-adjust thickness, so your control is limited mainly by patience.
The con: that sharpness is exactly why this one demands respect — the included hand guard is small and basic, and I would not use this Benriner barehanded. The thickness adjustment is also fiddly compared with OXO’s dial. Pair it with a cut-resistant glove and it’s the precision champion of the group.
Gramercy Adjustable Mandoline — Best Value
For most home cooks, this is the sweet spot. The Gramercy gives you a stainless V-blade, a dial with several useful thickness stops, and — the part I love — a pair of cut-resistant gloves in the box. That single inclusion does more for everyday safety than any clever guard, and it tells me the brand actually thought about how people get hurt. Slice quality on potato and carrot was genuinely close to the pricier models; only the cucumber showed a hair more drag.
The con: the plastic frame flexes slightly under hard pressure on dense vegetables, so you feel less planted than with the OXO. It’s a reassurance issue, not a performance one — the slices still came out even. At this price, with gloves included, it’s the easiest pick to recommend.
ONCE FOR ALL Safe Mandoline Slicer Plus — Best for Safety
If a previous mandoline scared you off the whole category, start here. The design is built around a deep, claw-style hand guard that keeps your fingers well above the blade, and the larger food bed means you’re not crowding your hand toward the edge to push small items through. It’s the model I’d hand to a nervous first-timer or a teenager without a second thought. Precision is perfectly good for everyday slaws, fries, and gratins.
The con: all that protective hardware makes it the bulkiest to clean, with more nooks where pulp hides, and the thickness range is narrower than the OXO or Benriner — it tops out before true deli-paper thinness. You trade a little finesse for a lot of peace of mind, and for many people that’s the right trade.
Fullstar All-in-One Vegetable Chopper & Mandoline — Best for Cleanup & Storage
This is the practical pick for a small kitchen. The mandoline blade sits over a catch container, so slices drop straight into the bin instead of all over the counter, and the whole thing — plus its chopper inserts — nests into one storage box. For weeknight slaw or quick pickle prep, the contained workflow genuinely saved me cleanup time. It also overlaps nicely with the affordable workhorses in my best budget kitchen gadgets list.
The con: it’s a jack-of-all-trades, so the mandoline blade isn’t as razor-fine as the dedicated slicers — the cucumber rounds were a touch thicker than I wanted. And with the most parts of any pick here, there’s the most to rinse and the most to misplace. But for catching slices and disappearing into a cabinet, nothing else came close.
Mandoline safety: how to never lose a fingertip
Every mandoline injury I’ve heard about happened the same way: someone skipped the guard “for the last few slices.” Don’t. The non-negotiables in my kitchen are simple. Always use the hand guard, even when it’s slower. Better yet, wear a cut-resistant glove on your guiding hand — it’s the cheapest insurance in cooking, and it’s why the Gramercy’s included pair matters. Lock or sheath the blade the moment you’re done, because a mandoline left blade-up in a soapy sink is how most cuts actually happen. And keep the blade sharp: a dull blade makes you push harder and slip, the same principle behind safe knife handling I cover in my kitchen tool care guide.
How to choose the right one for you
Match the tool to your priority. If you want the finest, most consistent slices and you’ll respect the blade, get the Benriner for pure precision or the OXO if you’d rather pay more for comfort and an easy dial. If you’re price-conscious but still want even results, the Gramercy with its bundled gloves is the value play. If the very idea of a mandoline makes you nervous, the ONCE FOR ALL’s deep guard removes most of the fear. And if counter mess and cabinet space are your real enemies, the Fullstar’s catch-container design wins. There’s no single “best” — there’s the best for how cautious you are and how much you’ll actually use it.
Frequently asked questions
Are mandoline slicers worth it?
If you regularly make slaws, gratins, chips, or anything that needs uniform slices, yes — a mandoline does in seconds what careful knife work takes minutes to match, and far more evenly. If you slice vegetables only occasionally, a good knife is enough.
Are cut-resistant gloves necessary?
They’re the single best safety upgrade you can make. The hand guard handles most of the work, but a glove protects you in the exact moments people get careless — the last few slices and the cleanup. I use one with every mandoline regardless of which guard it ships with.
Plastic or stainless steel frame?
The frame matters less than the blade and the stability. Plastic-bodied models like the Gramercy and Fullstar sliced cleanly in my tests; they just flex a bit more under heavy pressure. What you never want to compromise on is blade sharpness and a guard you’ll actually use.
The bottom line
For the cleanest, most consistent slices, the Benriner and the OXO Chef’s Mandoline 2.0 are in a class of their own — pick the Benriner for precision on a budget, the OXO for comfort and adjustability. For most home cooks, the Gramercy hits the right balance of price, performance, and safety, especially with its included gloves. And whichever you choose, buy the glove, use the guard, and sheath the blade — a mandoline is one of the most useful tools in a kitchen right up until the moment you get casual with it.
