6 Best Mandolines Under $20 in 2026

The OXO is the confident handheld in this lineup. It offers three set thicknesses of 1, 2.5 and 4 millimeters, a large non-slip handle and a stable foot. You can slice directly onto a plate, rest it on a cutting board, or hook it over a bowl so slices drop straight in.

The big handle is what sets it apart from smaller gadgets. Mandolines are about control, and a wide, grippy handle lets you keep the slicer steady while your other hand guides the produce. The foot stops it sliding around, and the bowl hook removes the awkward step of catching slices.

Three thicknesses cover most everyday jobs, from thin cucumber rounds to chunkier potato slices, yet they offer less nuance than a dial. It also still needs a steady hand on the food while you slice, since the listing mentions no hand guard. Against the Fullstar's four settings, it has fewer choices but a much sturdier hold. This is the safest all-round starter pick.

Fullstar's handheld puts four thickness settings, from 1 mm to 4 mm, into one compact body. A built-in julienne blade gives it a second cut without swapping parts, and the hand guard has stainless steel tips instead of plain plastic. It is described as the only handheld with four adjustable thicknesses.

The extra setting matters when you cook for fussy recipes. One millimeter is fine for gratin potatoes or cucumber salad, 4 mm is sturdy enough for hearty root vegetables, and the middle steps fill in the gaps. The stainless tips bite into the produce, which keeps the guard from skating off slippery vegetables.

The ceiling is 4 mm, so thick-cut fries or chunky slices are off the table, and the listing names no non-slip base. Compared with the OXO, it gives you more settings and a julienne blade but less foot stability. It suits cooks who want variety in a handheld frame and are comfortable steadying the tool themselves.

The PrepSolutions Adjust-A-Slice is the plainest tool in the group. The listing describes one green mandoline unit with adjustable slicing thickness and little else. There are no extra blades to track, so the whole product is one piece you can put in a drawer.

That simplicity is its appeal. With nothing to assemble and no inserts to lose, you pick it up, set the thickness and slice. It is the sort of tool that suits someone who reaches for a mandoline once or twice a month and does not want a learning curve.

The cost of simplicity is information. The listing gives few specs on blade or guard, and no thickness range is stated, so you must judge it by feel. Against the OXO's named 1, 2.5 and 4 mm, it is less precise on paper. Pick it only if you want the lowest-effort adjustable slicer and plan to use a separate guard or glove.

This NACOLUS version pairs five interchangeable blades with a sliding-track hand guard that wraps around the slicer body. The listing mentions a 1 mm straight slicer and a 2 mm shredder among the blade options, and says the tool is ready right out of the box with no assembly.

The hand guard is the feature worth caring about. Because it runs on a track, it keeps the vegetable pressed to the blade for straight, even cuts, which both improves slice quality and moves your fingers back from the edge. Five blades give you slicing, shredding and further cuts without needing separate gadgets.

More blades mean more things to store, and the listing does not publish a full thickness list for every blade. Compared with the Dexprosy, it is a flatter, more traditional slicer rather than a mini container tool. Choose it if finger safety is your top concern and you like to switch between slicing and shredding on the same board.

The ZHANG XIAO QUAN is a three-blade handheld that offers a straight slicer, a wavy slicer and a shredder. All the blades are stainless steel, and the listing says an included pusher keeps hands away from the cutting edge. It is aimed at potatoes, carrots, zucchini and similar produce.

The wavy blade is the fun extra. It gives crinkle-style slices for chips, pickles and decorative salads, a cut most basic mandolines skip. The pusher then holds the food against the blade so your fingers stay back, which is a sensible safety step at this price.

Three blades give less range than the five-blade NACOLUS, and the listing does not publish thickness measurements, so cuts are less predictable. Compared with the OXO, you gain a wavy cut and a shredder but lose a stable foot and bowl hook. Pick it if you like wavy chips and want a pusher built into the kit.

The Dexprosy is a small two-piece mini mandoline that slices, julienne cuts and grates ginger and garlic. It comes with a container to catch the food, a safety guard to protect fingers, and an ABS body with stainless steel blades. The listing says it rinses clean with water.

Its size makes it a very different tool from the full handhelds above. It is built for small jobs: a clove of garlic, a thumb of ginger, a handful of chocolate or cheese. The container catches the results, so you can go straight from the tool to the pan.

That compact format also limits it. A mini body cannot take a whole potato or cabbage, and the listing offers no thickness figures, so expect to cut larger vegetables down to size first and to work in small, careful batches. Against the OXO, it is much smaller and safer for tiny items but poor for bulk slicing. Choose it if you mostly want to grate aromatics and slice the occasional cucumber.
