9 Best Stainless Steel Adjustable Mandoline Slicers (November 2026)
The best stainless steel adjustable mandoline slicers include the OXO Good Grips Handheld Mandoline Slicer for everyday vegetable prep, the Benriner Japanese Mandoline Slicer for multiple cut styles, and the OXO Good Grips Large Adjustable Handheld Mandoline for large handheld prep.
On this page (3 sections)
The best stainless steel adjustable mandoline slicer for most kitchens is the OXO Good Grips Handheld Mandoline Slicer. Its three thickness settings, non-slip handle and stable foot cover everyday vegetable and fruit prep without adding a large countertop tool.
That simple setup suits cooks who slice a little each day rather than prep in large batches. You get clear choices for thin or thicker cuts, and you can work on a board, a plate or over a bowl.
The stainless steel blade helps slices stay even when food is held flat and the motion stays smooth. A non-slip handle and stable foot help the tool stay put with potatoes, onions, cabbage, cheese or fruit.
The window lets you see slices building below the surface. That helps with portion control, because you can stop when you have enough for a salad, a gratin or a simple side dish.
Choose Benriner if you want several blade styles. Its interchangeable blades and wider adjustment range suit cooks who move between straight slices, chunky cuts and julienne work.
Choose Gramercy if a stainless steel frame matters. That fits a countertop setup, with more thickness settings and a rotating blade cylinder for switching cut styles.
Choose PL8 if waffle cuts and an extra-wide deck fit your cooking. The wider deck gives large produce more room, and built-in blades reduce the need to handle loose parts.
For contained batch prep, SupMaKin and ONCE FOR ALL keep food collection closer to the slicer. A container or feed port can make repeated slicing tidier with several vegetables at once.
Care is part of the choice too. Some models are dishwasher safe, while others call for hand washing, so the cleanup time you want should shape your shortlist.
If you are comparing kitchen cutting tools more broadly, our vegetable slicer buying guide explains the main styles and features. That guide can help you place mandolines next to other slicers before you narrow the choice.
Start with the foods you slice most often, and think about storage as well. A compact handheld tool can live in a drawer, while a wider countertop model needs clear space.
Safety should stay central in any mandoline choice. Use the food holder, keep fingers back from the blade and stop when the piece gets small.

The best stainless steel adjustable mandoline slicers
The best stainless steel adjustable mandoline slicer depends on the cuts you make most often. The top picks cover simple preset slicing, broad thickness ranges, interchangeable blades, waffle cuts and contained prep.
Those ranges suit very different kitchens. A cook who slices cucumbers for a salad most days may want three clear settings, while a cook who makes fries, hash browns and stir-fries may want blades for julienne and chunky cuts.
Stainless steel can mean different things across these models. In some picks it refers mainly to the blade, while in others the frame or body also uses stainless steel, so the material should be read part by part.
Adjustment style matters as much as the listed range. Preset settings are quick to understand, a dial gives finer steps, and interchangeable blades add options but also add changes during prep.
Safety features vary by design. Food holders, guards, gloves, non-slip bases and hidden blades each help in different ways, and none of them removes the need for careful handling.
Cleaning needs differ too. Dishwasher safe models are easier after a busy prep session, while hand wash only models need a quicker rinse and a little more attention around the blade.
Our score weighs specs, features and buyer feedback against what you're shopping for. It is meant to sort the options by fit, not to claim that one style will suit every recipe or every kitchen.
Use the picks as a shortlist first. Then match the blade options, thickness range, safety setup and care instructions to the food you prepare most often.

1. OXO Good Grips Handheld Mandoline Slicer: Best for everyday vegetable prep
OXO Good Grips Handheld Mandoline Slicer: Best for everyday vegetable prep
- 1 mm, 2.5 mm and 4 mm settings
- Stainless steel blade
- Non-slip handle and stable foot
- Dishwasher safe
The OXO combines three useful thickness settings with a non-slip handle, stable foot and a window for viewing sliced food.
Pros
- Simple thickness choices
- Can hook over a bowl
- Food holder included
Cons
- Fewer settings than some adjustable models
- Handheld format
The OXO Good Grips Handheld Mandoline Slicer is the easiest fit for cooks who want a short list of useful settings. Its stainless steel blade adjusts to 1 mm, 2.5 mm or 4 mm, so you can move from thin cucumber slices to thicker potato or fruit pieces.
The large non-slip handle and stable foot give you two contact points while you work. You can slice onto a plate or cutting board, or hook the soft foot over a bowl to collect food as you go.
A window shows the slices below the cutting surface. That helps you see how much food has accumulated before you keep slicing another cucumber, onion or potato.
The food holder protects your hands and covers the blade when the slicer is stored. The body is stainless steel, the operation is manual and the product is dishwasher safe.
This is the strongest general pick if you value simple controls and easy placement over a wide range of specialty cuts. It is also a useful choice for cooks who want a compact handheld format.
2. Benriner Japanese Mandoline Slicer: Best for multiple cut styles
Benriner Japanese Mandoline Slicer: Best for multiple cut styles
- 0.5 to 8 mm adjustment
- 1 fixed and 3 interchangeable stainless steel blades
- BPA-free plastic body
- Top-rack dishwasher safe
Benriner gives you straight slices, coarse cuts and two julienne styles, with a dial that covers a broad thickness range.
Pros
- Four blade choices
- Wide 2.5 in slicing surface
- Safety guard and non-skid base
Cons
- Hand wash only
- Requires blade changes for different cuts
Benriner is the most flexible choice for cooks who need more than straight slices. It includes 1 fixed straight blade and 3 interchangeable blades for coarse, medium and fine tooth cuts.
The easy-turn dial adjusts thickness from 0.5 to 8 mm. That range covers thin slices for chips or garnish and thicker cuts for sturdy pieces that need to hold together during cooking.
The straight blade suits wider slices, while the toothed blades create chunky cuts or long, narrow julienne strips for foods such as potatoes, carrots and zucchini. Swapping blades takes a little planning, so it works best when you group similar cuts together.
Its BPA-free plastic body has a 2.5 in slicing surface, a large open handle and a non-skid rubber base. The slicing surface gives medium produce room to move, and the open handle keeps your grip away from the cutting area.
The groove can hook onto a bowl while the safety guard holds smaller pieces and helps protect fingers. That setup suits cooks who want slices to land in a bowl instead of spreading across the counter.
Benriner is a good match for recipes that shift between chips, fries, hash browns, stir-fries and garnish. It rewards a little setup time because each blade has a clear job.
The trade-off is care. The product data calls for hand washing, so cleanup takes more attention than a dishwasher-safe model, and blade changes need safe storage after use.
Choose this model when cut variety matters more than the simplest cleanup. Choose a model with preset settings or a container if you prefer fewer parts and a faster reset between tasks.
3. OXO Good Grips Large Adjustable Handheld Mandoline: Best for large handheld prep
OXO Good Grips Large Adjustable Handheld Mandoline: Best for large handheld prep
- 1 mm to 4 mm adjustment
- Stainless steel blade
- Wide ramp
- Food holder and dishwasher-safe care
The large OXO uses an adjustable dial and wide ramp for small or large vegetables while keeping the handheld setup compact.
Pros
- Half-millimeter dial adjustments
- Wide ramp
- Blade lock setting
Cons
- Product care says hand wash only
- Plastic material
The large OXO handheld model suits cooks who want an adjustable dial and a wider ramp in a handheld slicer. Its stainless steel blade adjusts from 1 mm to 4 mm in half-millimeter increments, giving you more steps than the smaller OXO model.
The ramp accommodates small and large vegetables, while its texture is designed to help keep food from sticking. A non-slip handle and base support steadier slicing, and notches let you work over a bowl.
The food holder is shaped for long and round foods. It also snaps onto the underside for compact storage, and the blade lock setting helps keep the blade in place when stored.
The product data lists the material as plastic and the care instruction as hand wash only, even though the feature summary mentions dishwasher-safe care. Check the care instructions that come with your unit before using a dishwasher.
Choose this model when half-millimeter adjustments and a larger handheld ramp matter more than interchangeable blades.
4. PL8 Professional Mandoline: Best for waffle cuts
PL8 Professional Mandoline: Best for waffle cuts
- Straight, waffle and julienne blades
- Four thickness choices
- Extra-wide stainless steel deck
- Non-skid feet
PL8 suits cooks who want built-in straight, waffle and julienne options without handling loose blades during normal changes.
Pros
- Waffle setting
- Extra-wide deck
- Fold-in feet
Cons
- Hand wash only
- Larger countertop footprint
PL8 is the best fit here if waffle cuts are part of your regular menu. Its built-in system covers straight, waffle and julienne cuts, with four slicing thickness choices.
The extra-wide stainless steel deck accommodates produce in different sizes. A safety hand guard helps hold food as it moves across the deck, while the adjustment dial changes between the built-in straight edge and waffle blades.
Because the blades are integrated, you don't need to manage loose parts during the normal switch between cut options. The non-skid feet add stability and fold in for more compact storage.
PL8 is larger and heavier than the handheld picks, with dimensions of 13.88 x 5.38 x 6.38 in and a listed weight of 1,410 g. It is a better match for a dedicated prep area than for a small drawer.
The product care instruction says hand wash only, so plan to rinse and clean it soon after use.
5. Gramercy Mandoline Slicer for Kitchen: Best for a stainless steel frame
Gramercy Mandoline Slicer for Kitchen: Best for a stainless steel frame
- 12 slice settings
- 4CR15 stainless steel blade
- Stainless steel frame
- Gloves, guard and cleaning brush included
Gramercy offers 12 thickness settings, a rotating blade cylinder and a stainless steel frame, plus several safety and cleaning accessories.
Pros
- Many thickness choices
- Blade guard and gloves included
- Top-rack dishwasher safe
Cons
- Larger than handheld picks
- Heavier 1.9 lb body
Gramercy stands out for its 12 slice settings, stainless steel frame and rotating blade cylinder. The 4CR15 stainless steel blade is designed for clean slices through onions, potatoes and other firm produce.
The built-in thickness dial moves from paper-thin to thick-cut. The rotating cylinder changes cutting styles without requiring you to handle a loose blade, which can make switching tasks more straightforward.
This model also includes cut-resistant gloves, a removable blade guard, a cleaning brush and a veggie holder. Its non-slip base and anti-slip feet are useful when you want the slicer to stay planted during repeated prep.
Gramercy is larger than the handheld options at 16.54 x 6.69 x 3.15 in and weighs 1.9 lb. That size may suit regular counter use, but it needs more storage planning.
Top-rack dishwasher care makes cleanup easier. Choose Gramercy when adjustment range, frame material and included safety accessories matter more than compact storage.
6. Benriner Mandoline Jumbo Slicer: Best for wide produce
Benriner Mandoline Jumbo Slicer: Best for wide produce
- 0.5 to 10 mm adjustment
- 5 in slicing surface
- Japanese stainless steel blade
- Non-skid rubber base
The Jumbo Slicer is made for broad produce such as cabbage, melon and eggplant, with a wide straight-edge blade and adjustable dial.
Pros
- Widest slicing surface here
- Broad thickness range
- Safety guard included
Cons
- Hand wash only
- Plastic body
The Benriner Jumbo Slicer is made for broad foods that need more room on the ramp. Its 5 in slicing surface and wide straight-edge blade suit cabbage, melon, eggplant and other larger produce.
An easy-turn dial adjusts thickness from 0.5 to 10 mm, the broadest range among the Benriner picks here. The safety guard holds smaller pieces, while the non-skid rubber base helps stabilize the slicer during use.
The body is BPA-free plastic with a handcrafted Japanese stainless steel blade. It has a large open handle and can hook onto a bowl to collect slices.
This is a strong choice for vegetable lasagna, coleslaw, casseroles and recipes that use large, even pieces. It is less useful if you mostly slice small foods and want multiple julienne styles.
The product care instruction says hand wash only, although the description also mentions top-rack dishwasher cleaning. Follow the instructions included with your unit.
7. SupMaKin Safe Mandoline Slicer for Kitchen: Best for contained batch prep
SupMaKin Safe Mandoline Slicer for Kitchen: Best for contained batch prep
- 0.1 to 8 mm adjustment
- Stainless steel V-shaped blades
- Feed port and container
- Foldable design
SupMaKin combines adjustable slicing with a feed port and container, which can help keep repeated vegetable prep in one place.
Pros
- Container included
- Foldable design
- Dishwasher safe
Cons
- Manual operation
- ABS plastic and stainless steel construction
SupMaKin suits meal prep and repeated vegetable slicing because its setup includes a feed port and container. The adjustable range runs from 0.1 to 8 mm, so you can select very thin slices or thicker cuts for foods such as potatoes and carrots.
The stainless steel V-shaped blades sit in an ABS plastic and stainless steel body. A non-slip base supports the manual slicing motion, while the foldable design takes less cabinet space when stored.
The included components are the vegetable food slicer, cleaning brush, feed port and cover container. That combination keeps the prep area more contained than a handheld model that slices directly onto a board or plate.
The product data names potatoes, sweet potatoes, onions, cucumbers, zucchini, lemons, carrots and apples among its recommended uses. It is dishwasher safe, which can shorten cleanup after larger prep sessions.
Choose SupMaKin when a container and compact folding design matter. If you prefer a stainless steel frame or a wider range of named blade styles, another pick may fit better.
8. ONCE FOR ALL Safe Mandoline Slicer Kitchen: Best for all-in-one cutting
ONCE FOR ALL Safe Mandoline Slicer Kitchen: Best for all-in-one cutting
- 0.1 to 8 mm adjustment
- Slicing, julienne, matchstick and dicing modes
- 420 stainless steel blades
- Collapsible design
ONCE FOR ALL focuses on several cutting modes in one collapsible tool, with hidden blades, a safety lock and a cleaning brush.
Pros
- Four cutting modes
- Container and cleaning brush
- Dishwasher safe
Cons
- Larger listed dimensions
- Manual operation
ONCE FOR ALL focuses on several cutting modes in one manual tool. It offers slicing, julienne, matchstick and dicing, with adjustable thickness from 0.1 to 8 mm.
Its 420 stainless steel blades are hidden within a collapsible ABS plastic and stainless steel design. A safety lock, container and cleaning brush support the setup, while the collapsible body helps reduce storage space.
This model works well for cooks who want several preparation styles without changing a loose blade. The product data lists potatoes, sweet potatoes, French fries, onions, cucumbers, zucchini, celery, lemons, carrots, apples and other fruits and vegetables as recommended uses.
The trade-off is that more modes can mean more parts and more cleaning points. Rinse away food residue soon after use, and use the small brush for areas that are hard to reach.
Choose ONCE FOR ALL if dicing and matchstick cuts matter as much as slicing. For a simpler tool with fewer choices, OXO is easier to understand.
9. XAYCDEHN Mandoline Slicer: Best for included hand protection
XAYCDEHN Mandoline Slicer: Best for included hand protection
- Adjustable thickness
- Stainless steel blade and body
- Food holder and cut-resistant glove
- Cleaning brush
XAYCDEHN pairs adjustable slicing with a food holder, cut-resistant glove and cleaning brush for a basic manual setup.
Pros
- Glove included
- Food holder included
- Stainless steel construction
Cons
- Hand wash only
- Exact thickness range is not stated
XAYCDEHN is a practical choice if you want a food holder and glove included with a stainless steel manual slicer. Its round stainless steel blade supports adjustable slicing and julienne work for potatoes, onions, tomatoes, salads and fruit.
The non-slip handle and feet are designed to reduce movement while slicing. The included cut-resistant glove adds another layer between your hand and the blade, but it does not replace careful use of the food holder.
The package includes a cleaning brush and glove. The body and blade are stainless steel, and the listed dimensions are 15.76 x 6.69 x 1.18 in.
The exact thickness range is not stated in the product data, so this model is less suitable if you need a specific measurement such as 1 mm or 4 mm. The care instruction says hand wash only.
Choose it when included hand protection and stainless steel construction are priorities. Choose OXO or Benriner when a clearly stated adjustment range matters more.
How to choose an adjustable stainless steel mandoline slicer
Choose the slicer by its adjustment method, blade options, safety setup and cleaning needs. Stainless steel can refer to the blade, the frame or both, so check which part uses the material before deciding.
Which adjustment range fits your recipes?
A narrow range can be useful if you mainly make one type of slice. The OXO handheld models offer defined settings, while Gramercy, Benriner, SupMaKin and ONCE FOR ALL cover more steps.
The largest stated range here is Benriner Jumbo at 0.5 to 10 mm. SupMaKin and ONCE FOR ALL start at 0.1 mm, but a very fine setting still requires careful control and a secure food holder.
Do you need julienne, waffle or dicing cuts?
Choose Benriner if you want interchangeable straight, coarse, medium and fine blades. PL8 is the clearest choice for waffle cuts because that setting is built into its design.
Gramercy uses a rotating blade cylinder for straight and julienne styles. ONCE FOR ALL adds dicing and matchstick modes, making it useful when you want several cuts from one tool.
For apple prep, a firm apple and a secure food holder matter more than a long feature list. See our guide to the best mandoline slicer for apples for more focused advice.
What safety features should you use?
Use the food holder from the first slice and keep the blade pointed away from your fingers. A non-slip base, stable foot or non-slip handle can help reduce movement, but none of these features makes the blade harmless.
Gramercy includes gloves and a removable blade guard. XAYCDEHN includes a cut-resistant glove, while OXO, Benriner, SupMaKin and ONCE FOR ALL include food-holding or contained-prep features.
For step-by-step handling, read how to use a mandoline vegetable slicer. If you are considering meat, read can you use a mandoline slicer for meat before trying it.
How should you clean and store one?
Clean the slicer soon after use so food does not dry around the blade or adjustment parts. Dried residue can make the next prep harder and can leave odors that are tougher to remove later.
Follow the exact care instruction for your model, because some products here are dishwasher safe while others call for hand washing. That difference can affect how often you will want to use the tool.
Rinse first, then wash with warm water and mild soap where hand washing is required. Pay attention to grooves, dials and blade edges, where small pieces of food tend to hide.
Dry the slicer well before storage. Moisture left around the blade or in crevices can affect the tool over time and make the next cleanup less pleasant.
Keep the food holder with the slicer and cover or lock the blade when the design includes that feature. Storage safety matters because a sharp blade in a drawer should not be the first thing a hand finds by feel.
Gramercy includes a removable blade guard, while the OXO handheld model has a food holder that covers the blade for storage. Those details help with both safety and tidiness in a busy kitchen.
Store the slicer where it fits your routine. A handheld model can go in a drawer, while a larger countertop model may need a cabinet shelf or a clear counter spot.
Check the blade area before the next use. Look for stuck food, looseness around adjustment parts or damage to holders and guards, and set the tool aside if anything feels off.
Stainless steel does not mean every part is stainless steel. Some models pair a stainless steel blade with a plastic body, while others use stainless steel more broadly.
That distinction affects weight, care and storage. A plastic body may be lighter and easier to move, while a stainless steel frame may feel more fixed on the counter during repeated slicing.
Choose care based on the whole tool, not the blade alone. Seals, handles, feet and adjustment parts may need gentler treatment even when the blade itself can handle a rinse.
If you are also comparing dehydrator trays, our Plastic vs Stainless Steel Dehydrator Trays: A Quick Overview explains why material choice depends on the job. The same idea applies here, since the right material often depends on where it sits on the tool.
Set a simple routine after each use. Rinse, wash as directed, dry fully, add the holder or guard and store the slicer in the same place every time.
That routine keeps prep safer and makes the next slicing session faster. It also helps you notice wear early, before a loose part or a dull edge affects the cut.
Which stainless steel adjustable mandoline slicer should you buy?
Pick the OXO Good Grips Handheld Mandoline Slicer if you want dependable everyday slicing with three clear settings and a stable handheld design. It suits cucumbers, potatoes, onions, fruit and other regular prep without taking over the counter.
Pick Benriner if you need several blade styles. The interchangeable blades and dial adjustment fit cooks who make straight slices one day and julienne or chunky cuts the next.
Pick Gramercy if you want 12 settings, a stainless steel frame and included safety accessories. Its rotating blade cylinder and non-slip base suit a more fixed prep setup.
Choose PL8 for waffle cuts. The extra-wide deck and built-in straight, waffle and julienne options make it a better match for cooks who use those cuts on a regular menu.
Choose Benriner Jumbo for wide produce. The 5 in slicing surface and 0.5 to 10 mm range suit cabbage, melon, eggplant and other broad foods that need more ramp space.
Choose SupMaKin for a container-based setup. The feed port, container and foldable design help keep batch prep contained and storage more compact.
Choose ONCE FOR ALL for several built-in cutting modes. Slicing, julienne, matchstick and dicing in one collapsible tool can suit cooks who like variety without separate blades.
If an included glove is your main priority, XAYCDEHN is the most direct match. The food holder, glove and cleaning brush support a basic manual setup for everyday slicing and julienne work.
The best stainless steel adjustable mandoline slicer is the one whose adjustment range, cut styles and safety setup match the food you prepare most often. Start there, then check care and storage before you decide.

Frequently asked questions
What is the best stainless steel adjustable mandoline slicer?
The OXO Good Grips Handheld Mandoline Slicer is the best stainless steel adjustable mandoline slicer for simple daily vegetable prep. It has a stainless steel blade, a non-slip handle, a stable foot and 1 mm, 2.5 mm and 4 mm settings.
Choose Benriner instead if you need interchangeable blades and julienne cuts.
Are stainless steel mandoline slicers safer?
Stainless steel construction does not remove the cutting risk. Use the food holder, keep your fingers away from the blade and follow the care instructions for the model you choose.
Some picks here include gloves, guards or hidden blades, but safe handling still matters with every manual mandoline.
What thickness should you use on a mandoline slicer?
Use a thin setting for chips, garnishes and quick-cooking slices, and a thicker setting for sturdy pieces or fries. The right choice depends on the recipe and the food.
Models here range from 0.1 mm to 10 mm, while the OXO handheld models use a smaller set of preset choices.
Can you use a mandoline slicer for apples?
Yes, a mandoline can slice apples when the fruit is firm and held securely with the food holder. Start with a moderate thickness, keep the apple flat against the ramp and stop before your fingers reach the blade.
For apple-specific tools, see our guide to the best apple slicer stainless steel.
