6 Best Mandolines Under $30 in 2026

The ONCE FOR ALL slicer hides its sharp blade inside the housing, which is the clearest safety idea in the lineup. The listing describes eight thickness modes covering 0.1 to 8 millimeters, with no blade change required, and 420 stainless steel blades. It is a gray body described as fast, uniform and easy to set up and clean.

The benefit of a hidden blade is simple: your hand never crosses the edge. You choose a thickness, load the food and push, so there is no exposed platform to catch a knuckle. Eight modes then give you a wide range of slice thicknesses from crisp-thin to hearty.

Enclosed slicers can only take food that fits the feeding port, so wide cabbages or large onions must be cut down first. Against the open-platform OXO it is safer but less flexible with big produce. Pick it if you want the strongest protection and mostly slice small to medium vegetables. Keep the feeding port clear of stray peel, and expect to spend a minute rinsing the housing after each session, because starch dries quickly on stainless.

The SupMaKin works on a push-handle principle. Built-in blades sit inside the body, the thickness is chosen from 0.1 to 8 millimeters, and you push the handle down to deliver uniform slices without touching an edge. The listing calls the stainless steel blades heavy duty, even for hard vegetables.

The push handle replaces sliding the food by hand across a platform, which is where most mandoline accidents happen. It also gives you mechanical leverage on hard produce such as potatoes and carrots, since you press down instead of stroking. The listing promises quick, uniform slices compared with a knife.

Two drawbacks follow from the enclosed shape. The housing limits how big a whole vegetable can be, and cleaning the inside takes extra care so pulp does not linger. Compared with the ONCE FOR ALL, the idea is similar but the operation is a downward push rather than a feed port. It is a strong choice for cooks who find stroking a platform stressful. Press smoothly and let the blade do the work rather than slamming the handle, which keeps cuts even and protects the mechanism over the long run.

The PUPZY packs five functions and a 0.1 to 8 millimeter thickness range into one slicer with a handguard. According to the listing it covers slicing, julienne cuts and strips, and it is described as simple and precise to use. It is the all-rounder of the group.

The open design lets you work with larger produce than the enclosed slicers allow. A potato, a cucumber or a block of cheese can pass across the deck while the handguard secures the food. With the wide range, it handles delicate crisps and chunky slices from the same body.

The handguard is described in general terms, so you cannot judge how well it grips, and blade material is not named. Against the SupMaKin, it needs more hand skill but accepts bigger vegetables. It suits cooks who want flexibility, a familiar stroking action and a wide range at a moderate price. Begin at a thick setting, learn the stroke on a cucumber, then move toward the thin end once the motion feels automatic.

The NACOLUS combines a sliding-track hand guard with five interchangeable blades. The guard wraps securely around the slicer body, keeping vegetables in place for straight, even cuts. The listing names a 1 mm straight slicer and a 2 mm shredder among the blades and says the tool needs no assembly.

The track makes this the best open-platform answer to finger safety. Instead of holding the food with bare fingers, you clamp it in the guard and slide it along, which keeps your hand back and your cuts parallel. Five blades then let you move from slicing to shredding on the same body.

Blade swaps mean touching edges, and the listing does not publish a complete thickness list. Compared with the ZHANG XIAO QUAN, the guard is more sophisticated but there is no wavy blade. Pick it for a classic mandoline experience with real hand protection. Slide the guard slowly and keep the unused blades in a covered box so a drawer search never ends in a nick.

The OXO is the straightforward handheld in a group full of safety engineering. Three thicknesses of 1, 2.5 and 4 mm are selected on the body, and a large non-slip handle and stable foot hold it steady. A hook lets it perch over a bowl so slices drop straight in.

Where enclosed slicers solve the problem by hiding the blade, the OXO solves it by making your grip secure and your position stable. A big handle spreads force across your palm, and the foot keeps the tool planted so you are not wrestling it on a board. It is the easiest model here to pick up and use without learning anything new.

The cost is control over the food hand, since the listing describes no guard, and the settings are fixed at three. Beside the PUPZY with its 0.1 to 8 mm span, it is far narrower. Choose it if you value comfort, familiarity and a reliable hold over the widest range. For most weeknight salads, sides and roasting trays, three thicknesses are all the control a home cook ever uses.

The ZHANG XIAO QUAN offers three stainless steel blades: one for plain slices, one for wavy slices and one for shredding. The listing says the blades are sharp and long lasting, and an included pusher keeps hands away from the edge. It is aimed at potatoes, carrots, zucchini and similar firm produce.

The wavy blade stands out in this lineup, since none of the enclosed slicers offer a crinkle cut. It is a handy tool for crisps, pickles and salad toppings. The shredder adds a second everyday use, turning carrots and cucumbers into slaw ingredients.

Three blades give less range than the NACOLUS, and the listing provides no thickness measurements. The pusher is a modest safety measure compared with the hidden blades of the ONCE FOR ALL. It suits cooks who want crinkle cuts and a pusher at a gentle price. Use the pusher on every pass, even when the vegetable still looks long enough to hold, because the final inch is where fingers drift toward the edge.
