6 Best Adjustable Mandoline Slicers in 2026
Six adjustable mandoline slicers compared on thickness range, guard design, stability and cleanup, with safety-first picks for handheld and countertop use.
At a Glance
The word adjustable on a mandoline can mean three very different things: a dial that moves the blade deck, a few fixed notches you click between, or a set of built-in blades that you switch without handling the edge. All of them let you choose slice thickness, but they differ a great deal in how safe and stable the process feels.
We evaluated six adjustable mandolines using product specs and buyer feedback, focusing on thickness range, how the guard or food holder works, whether the base stays put, and how risky the blade is to clean and store. The lineup spans the Gramercy countertop slicer, the SupMaKin enclosed pusher design and four handheld models.
Mandolines are the tool that cuts more fingers than almost any other in the kitchen, so each pick notes its safety tradeoff plainly. The decision tables later in the guide connect your cooking habits to a named model. We do not claim hands-on testing; the notes reflect listings and reported experience.
6 Criteria to Look For Before Buying a Adjustable Mandoline Slicer
Key buying criteria so you get the right fit the first time.
Thickness range and increments
Adjustable should come with a stated range so you know the tool matches your recipes. The Gramercy gives 12 settings, the SupMaKin runs 0.1 to 8 mm, the Fullstar offers 1 to 4 mm in four steps, and the OXO and Ibergrif each provide three. For chips and gratin you want 2 to 3 mm, while paper-thin cucumber needs under 1 mm. Choose the model whose range includes your most frequent cut with room to spare.
Guard and food holder
The guard sits between your hand and the blade, so its quality is your first safety measure. The Fullstar uses stainless steel guard tips for grip, the Ibergrif includes a holder, and the SupMaKin removes the issue with built-in blades and a push handle. Many holders grip poorly on small or soft items, so use a cut-resistant glove as a second layer when slicing the last inch.
Base stability
A slicer that slides mid-stroke is dangerous. The Gramercy uses anti-slip feet and a heavy build, and the OXO has a stable foot that also hooks over a bowl. Lighter handhelds depend on how firmly you press on a board. Always place a damp towel under any unit without a rubber base before you begin.
Blade type and handling
Open blades are fast and clean-cutting but demand respect. The Gramercy uses a 4CR15 stainless blade on a rotating cylinder, so changing cut style does not require lifting a blade. The SupMaKin has built-in stainless blades with no exposure. The Ibergrif adds a blade lock for storage, which cuts accident risk during drawer storage.
Cleaning and storage
Most mandoline injuries happen at the sink or in the drawer. Wash blades with a brush, never a sponge pressed against the edge, and rinse enclosed designs like the SupMaKin straight after use so food does not dry inside. The Gramercy has more surfaces to wash than the handhelds, and the handheld OXO and Fullstar slide into a drawer far more easily.
Produce size and feed method
Match the tool to what you slice. The SupMaKin's housing limits whole vegetable size, handhelds like the OXO suit potatoes, cabbage and onions, and the Gramercy handles larger items with a stable deck. Soft tomatoes need a very sharp blade and short steady strokes. If you slice big squash or watermelon rind, a countertop deck is easier than a handheld.
6 Best Adjustable Mandoline Slicers in 2026
Gramercy Mandoline Slicer With 12 Slice Settings
About this pick
The Gramercy is the most complete adjustable slicer in this group. A built-in dial offers 12 slice settings, from paper-thin to thick-cut, and a rotating blade cylinder switches between cutting styles without you ever unbolting or lifting a blade. The blade is a professional 4CR15 stainless steel, described as holding an edge.
Stability is a strength. A non-slip base with anti-slip feet keeps the slicer from creeping on the counter, which is the most common cause of accidents on lightweight models. The substantial build suggests a tool you set down and leave in place.
The cost of all that capability is space, because it takes more counter and cabinet room than the handheld OXO, Fullstar or Ibergrif. The blade is open, so you need a food holder or a cut-resistant glove every time, and the larger tool has more surfaces to clean. For a cook who slices potatoes, cucumbers and onions for the whole family, the precision justifies it.
Best for: Cooks who want precise, repeatable thickness across many different vegetables.

- Settings: 12 slice thicknesses
- Blade: Professional 4CR15 stainless steel
- Adjustment: Built-in dial
- Base: Anti-slip feet
Pros
- +Thickness dial offers twelve settings in one tool
- +Rotating cylinder skips risky blade swaps
- +Anti-slip feet keep the base from creeping
- +Pro-grade 4CR15 blade holds a sharp edge
Cons
- −Takes more counter and cabinet space than handhelds
- −Open blade needs extra care and a holder
- −Larger tool has more surfaces to clean
SupMaKin Safer Mandoline Slicer, 1-8 mm
About this pick
The SupMaKin takes the opposite approach from an open-blade mandoline. The blades are built in and enclosed, and you push a handle to move food through them, so fingertips never ride along the edge. Thickness is adjustable from 0.1 mm up to 8 mm, a wider range than most handheld models.
The stainless steel blades are described as heavy duty for hard produce, and the push handle replaces the habit of sliding food by hand. This design gives the most distance between hand and blade of anything in the lineup, which is why it appeals to cautious cooks and anyone with unsteady hands.
The tradeoffs are structural: the housing limits how large a whole vegetable you can feed, and the closed design is harder to inspect, so you need to rinse the inside right after use. Compared with the Gramercy it gives up the easy visual access and the 12 click settings, but gains safety. Compared with the OXO handheld, it needs more storage space.
Best for: Safety-minded cooks who would rather never touch a blade.
Check price on AmazonSpecs
- Thickness range: 0.1 to 8 mm
- Blades: Built-in stainless steel
- Action: Push handle
- Style: Enclosed slicer
Pros
- +Built-in blades stay out of reach of fingers
- +Thickness runs from 0.1 mm to 8 mm
- +Push handle replaces sliding food by hand
- +Heavy-duty stainless blades cut hard produce
Cons
- −Housing limits the size of whole vegetables
- −Inner cleaning needs a rinse right after use
- −Closed design is harder to inspect
OXO Good Grips Handheld Mandoline Slicer
About this pick
The OXO handheld slicer simplifies the adjustable idea down to three thickness settings: 1 mm, 2.5 mm and 4 mm. A large non-slip handle and a stable foot keep the tool steady, and it can hook over a bowl or slice straight onto a plate or board.
Its strength is how few things you have to think about. You pick one of three thicknesses, hold the big handle, and slice potatoes, cabbage, onions or cheese. The foot stops it sliding, and the hook means slices fall directly into the bowl, which cuts the awkward motions that lead to slips.
Three settings is also the limit, so it cannot match the Gramercy's 12 or the SupMaKin's 0.1 to 8 mm range. You also need a steady hand on the food while slicing, so pair it with a holder or glove. For salads, gratins and chips, three well chosen thicknesses are enough, and the compact size beats the countertop models in a small kitchen.
Best for: Everyday slicing where a big comfortable handle matters more than thickness range.
Check price on AmazonSpecs
- Thicknesses: 1 mm, 2.5 mm, 4 mm
- Handle: Large non-slip
- Support: Stable foot
- Use: Hooks over a bowl or rests on a board
Pros
- +Large non-slip handle gives a confident hold
- +Stable foot keeps the slicer from sliding around
- +Hooks over a bowl for hands-free catching
- +Three thicknesses cover most slicing jobs
Cons
- −Offers only three thickness settings
- −Needs a steady hand on the food while slicing
Fullstar Handheld Mandoline Slicer And Julienne Cutter
About this pick
The Fullstar handheld slicer adds one more setting than the OXO, giving four thickness options at 1, 2, 3 and 4 mm, plus a built-in julienne blade that turns the same tool into a matchstick cutter. The hand guard has stainless steel tips, described as offering better grip than flimsy plastic ones.
That guard detail matters because a holder that skids off produce is no protection at all. Metal tips bite into the food, keep fingers back and give a more stable push stroke. The 2-in-1 layout also saves a second gadget, which is useful if you make slaw, fries or garnishes.
It still has the weakness of any handheld: the user supplies the stability. There is no listed non-slip base, unlike the Gramercy, and its range tops out at 4 mm, well short of the SupMaKin at 8 mm. For thin slicing and julienne in a small drawer, it is the best handheld in the group for its guard and its extra setting.
Best for: Salads and slaw where thin slices and julienne cuts are both needed.
Check price on AmazonSpecs
- Thicknesses: 1, 2, 3 and 4 mm
- Extra blade: Built-in julienne
- Guard: Stainless steel tips
- Form: Handheld
Pros
- +Four settings from 1 mm to 4 mm
- +Stainless steel guard tips grip produce
- +Built-in julienne blade adds a second cut
- +Compact handheld size stores easily
Cons
- −Maximum thickness stops at 4 mm
- −No non-slip base is named in the listing
Ibergrif Handheld Adjustable Vegetable Slicer
About this pick
The Ibergrif is a handheld slicer built around three adjustable thicknesses, a food holder and a blade safety lock. The stainless steel blade is sharp, and the lock secures the edge for storage and cleaning, which is where many accidental cuts happen after the cooking is over.
The included holder keeps fingertips at a distance from the blade, and a non-slip design supports a steadier stroke. The listing frames it as meal prep for salads, chips and small kitchen use, and it is compact enough for a small drawer.
The lighter build leaves more of the control to your own hands, and the holder adapts poorly to odd-shaped produce. Against the OXO handheld, it has the same three thicknesses but adds the blade lock. Against the SupMaKin, it needs more attention while cutting. If you want a low-footprint option that locks the blade away, it is a practical choice.
Best for: Small kitchens that want a lockable blade and a compact slicer.
Check price on AmazonSpecs
- Thicknesses: 3 settings
- Holder: Included food holder
- Lock: Blade safety lock
- Blade: Stainless steel
Pros
- +Blade safety lock secures the edge for storage
- +Includes a food holder for fingertip distance
- +Three thickness settings suit salads and chips
- +Compact enough for a small drawer
Cons
- −Lighter build leaves more work to your own control
- −Holder adapts poorly to odd-shaped produce
- −Only three thickness settings to choose from
PrepSolutions Adjust-A-Slice Mandoline Slicer
About this pick
The PrepSolutions Adjust-A-Slice is positioned around one idea, adjustable slicing thickness, for all your prep needs. The listing is short on detail: it confirms a single green mandoline in the box and the adjustable thickness feature, without giving a range, blade material or guard description.
That limited information is itself a data point. With the Gramercy listing 12 settings and a 4CR15 blade, or the Fullstar listing 1 to 4 mm and steel guard tips, this pick leaves more to assume. The adjustable design means you can pick thicker or thinner cuts without swapping blades, which is the main benefit here.
For that reason it works best as a straightforward, low commitment slicer for someone who values simplicity and is willing to check the dimensions before buying. Confirm whether a holder is included and how the base grips the counter, since the listing does not say. If safety features matter most, the SupMaKin or Ibergrif document theirs more clearly.
Best for: Basic adjustable slicing for cooks who prefer a minimal tool.

- Feature: Adjustable thickness
- Contents: One mandoline
- Color: Green
- Style: Hand-operated slicer
Pros
- +Adjustable thickness covers different prep jobs
- +Single unit with no extra blades to store
- +Simple hand-operated design is easy to learn
Cons
- −Listing gives few specs on blade or guard
- −Thickness range is not stated in the listing
How We Evaluated These Adjustable Mandoline Slicers
Each pick was assessed across 5 criteria weighted for real-world use.
Adjustment range
We compared documented thickness ranges and steps. The Gramercy leads with 12 settings, the SupMaKin spans 0.1 to 8 mm, the Fullstar offers four steps from 1 to 4 mm, and the OXO and Ibergrif offer three. The PrepSolutions listing states no range, which counted against it.
Safety design
Based on product specs, we weighed guards, holders, blade locks and enclosed blades. The SupMaKin hides its blades, the Ibergrif locks its blade, the Fullstar uses steel guard tips, and the Gramercy relies on a rotating cylinder. Designs reducing blade contact scored highest.
Stability
We looked for anti-slip feet, hooks and non-slip handles, such as the Gramercy feet and the OXO stable foot. Handhelds without a listed base lost points.
Cutting performance
We read blade material and buyer feedback on evenness and hard produce. The 4CR15 stainless blade on the Gramercy and the heavy-duty stainless blades on the SupMaKin were credited for hard vegetables.
Storage and cleanup
We compared size, parts and cleaning risk. Handhelds like the OXO, Fullstar and Ibergrif store in a drawer, while the Gramercy and SupMaKin need more room. Lineup positioning: Gramercy leads on precision, SupMaKin on safety, OXO on grip.
How to Choose the Right Adjustable Mandoline Slicers
By Primary Use
Think about what you slice most often.
| Use | Best pick | Reason |
|---|---|---|
| Potato chips and gratin | Gramercy Mandoline Slicer With 12 Slice Settings | Twelve dial settings give repeatable thickness |
| Cautious daily slicing | SupMaKin Safer Mandoline Slicer, 1-8 mm | Built-in blades and push handle |
| Salad and cabbage | OXO Good Grips Handheld Mandoline Slicer | Large handle and 1, 2.5, 4 mm settings |
| Slaw and julienne | Fullstar Handheld Mandoline Slicer And Julienne Cutter | Built-in julienne blade |
| Small drawer storage | Ibergrif Handheld Adjustable Vegetable Slicer | Compact with blade lock |
Pick the cut you make weekly, not the one you might make once.
By Budget
Relative tiers only.
| Tier | Pick | Tradeoff |
|---|---|---|
| Entry | PrepSolutions Adjust-A-Slice Mandoline Slicer | Few listed specs |
| Entry plus | Ibergrif Handheld Adjustable Vegetable Slicer | Only three thicknesses |
| Mid | OXO Good Grips Handheld Mandoline Slicer | Three settings |
| Mid plus | Fullstar Handheld Mandoline Slicer And Julienne Cutter | 4 mm maximum |
| Premium | Gramercy Mandoline Slicer With 12 Slice Settings | Takes more space |
The SupMaKin sits between mid and premium for the safety it buys.
Open Blade vs Hidden Blade
The difference is how close your hand gets to the edge.
Open blade
The Gramercy, OXO, Fullstar, Ibergrif and PrepSolutions expose a blade across which you slide food. This gives full control and easy inspection, but needs a holder or glove for the last inch. Choose it for speed and large produce.
Hidden blade
The SupMaKin keeps blades enclosed and uses a push handle, so fingers never travel across an edge. It limits whole vegetable size and needs prompt rinsing. Choose it if safety outranks flexibility.
Cautious cooks pick hidden; experienced cooks pick open with a glove.
Handheld vs Countertop
Footprint and stability pull in opposite directions.
| Setup | Pick | Reason |
|---|---|---|
| Countertop deck | Gramercy Mandoline Slicer With 12 Slice Settings | Anti-slip feet and a stable deck |
| Enclosed countertop | SupMaKin Safer Mandoline Slicer, 1-8 mm | Push-handle housing |
| Over a bowl | OXO Good Grips Handheld Mandoline Slicer | Hooks over a bowl |
| Drawer friendly | Fullstar Handheld Mandoline Slicer And Julienne Cutter | Slim handheld |
If you slice weekly in volume, the deck wins.
For Safe Handling Specifically
Safety features should be your tiebreaker.
Look for
A guard with grip, a blade lock, anti-slip feet and, ideally, a cut-resistant glove for the last inch. Also check that the thickness adjustment can be changed without touching the blade edge, since that moment is a common source of nicks. Short, steady strokes on firm produce are safer than forcing soft items.
In this comparison
The SupMaKin hides its blades, the Ibergrif locks its blade, the Fullstar has steel guard tips, and the Gramercy has anti-slip feet. Wear a glove with any open blade.
Never slice in a hurry, and never catch a falling slicer.
When to Spend More
Pay more only where it protects you or saves time.
| Spend more if | Save if |
|---|---|
| You slice often and want the Gramercy dial and anti-slip feet | You slice rarely, so the OXO is enough |
| Safety is your concern and the SupMaKin enclosed blades fit | You are confident with an open blade and a glove |
| You make slaw and fries with the Fullstar julienne blade | You only need slices |
| You store tools in a drawer and want the Ibergrif lock | You keep it on the counter |
A cheap slicer is not a bargain if it slips.
Frequently Asked Questions
What does adjustable mean on a mandoline?
It means you can change slice thickness, but the method varies. The Gramercy uses a dial with 12 settings, the OXO offers 1, 2.5 and 4 mm, and the SupMaKin adjusts from 0.1 to 8 mm. Look for stated numbers rather than the word alone.
Are mandolines dangerous?
Yes, because the blade is very sharp and the food gets small near the end. A guard, a cut-resistant glove and a stable base reduce the risk. Stop slicing when the produce gets short rather than pushing your fingertips through.
Is a hidden-blade slicer safer?
Generally, since the SupMaKin keeps blades enclosed and uses a push handle. It still needs careful cleaning, and the housing limits food size. Safer does not mean risk free, so rinse promptly and store it out of reach.
What thickness should I use for potato chips?
Most cooks use about 1 to 2 mm for crisp chips and about 3 to 4 mm for gratin. The Fullstar offers 1, 2, 3 and 4 mm, and the OXO offers 1, 2.5 and 4 mm. A dial slicer like the Gramercy lets you fine tune.
How do I clean a mandoline safely?
Use a brush or a long handled tool and rinse under running water, keeping fingers off the edge. Never wipe a blade with a sponge. Lock the blade if the model has a lock, like the Ibergrif, before storage.
Do I need a cut-resistant glove?
It is a strong idea for any open-blade model. Gloves let you keep slicing past the point where the holder stops gripping. They are not a substitute for care, but they add a real second layer.
Can a handheld replace a countertop mandoline?
For salads, chips and small batches, yes. The OXO, Fullstar and Ibergrif are enough for most households. For large volumes or big vegetables, the Gramercy deck or the SupMaKin housing is easier.
