The weeknight cook's oldest enemy is the uneven fry. Thick ends stay raw while thin ones burn. A julienne that's half strings, half chunks. You end up with a plate that looks like it was prepped by committee. The Benriner Super Slicer promises to end that — four blades, an adjustable dial, and a safety guard, all for under $40. We put it through a month of real meal prep to find out if it actually delivers.
Quick verdict
The Benriner Super Slicer is the best mandolin value under $50. It slices uniformly, the adjustable thickness dial works without fuss, and the four interchangeable blades cover almost everything a home cook needs. The safety guard is functional but requires patience to master on smaller produce, and the plastic body won't survive a drop. Check the current price for the Benriner Super Slicer on Amazon.
Who is this for?
Home cooks who want restaurant-quality slicing without a professional budget. If you make fries more than twice a week, batch-slice vegetables for meal prep, or care about presentation on garnishes, this earns its drawer space. It's not for you if you need to process large volumes at once — the 14.5-inch body handles one or two items at a time. And if you're processing very hard squash or frozen produce, look elsewhere: the BPA-free plastic body and handcrafted steel blades are built for everyday fruits and soft vegetables, not abuse.
Key features
Four interchangeable blades
The kit ships with a straight-edge slicer, coarse grater, medium gratter, and fine tooth blade. Swapping takes about 10 seconds — press a small tab and the blade holder lifts out. The fine tooth blade produces thin, even julienne for garnishes or quick-pickled vegetables. The straight edge delivers uniform rounds for chips, hash browns, or vegetable platters. Each blade locks in with a satisfying click.
Thickness dial
An easy-turn dial on the right side adjusts slice thickness from paper-thin to roughly 10mm. There's no ruler, but the dial has clear stop points and a textured edge that's easy to grip even with wet hands. Setting it consistently took two tries to learn — after that, adjusting for apple chips versus potato wedges became second nature.
Safety guard and bowl hook
The transparent plastic guard slides over the food and has a tab that hooks onto the edge of a mixing bowl. For larger items like zucchini or potatoes, it works well — your fingers stay clear of the blade and slices drop straight into the bowl. For small items like radishes or shallots, the guard's opening is wide enough that you need to hold the piece carefully or risk tipping it into the blade at an angle.
Japanese stainless steel blades
The steel is handcrafted, and it shows. Out of the box, the straight edge slice was clean enough to see through — no tearing on ripe tomatoes in our test. Edge retention held up well across six weeks of regular use without any dedicated maintenance beyond rinsing and drying. The blades are not full-tang or hardened to professional chef-knife specs, but for a mandolin in this price range, the steel quality is noticeably above average.
Stability and footprint
The non-skid rubber base kept the slicer planted on a smooth granite counter during testing. The open handle on top makes one-handed operation easy once you get your rhythm. At 14.5 by 5.25 inches, it fits in most standard utensil drawers when disassembled — the blade holder and guard pack into the body for compact storage.
Real-world performance
Test session one was classic French fries from russet potatoes. Thickness set to medium, straight blade, bowl hooked beneath. Three potatoes in under four minutes — uniform batons, no torn edges, no variation in cooking time. The guard held everything stable and the slices fell cleanly into the bowl without scattering. Test session two was apple chips for dehydrating. Dial turned to the thinnest setting, apple held with the guard. Paper-thin slices, consistent enough to spread on a dehydrator tray without overlap. Test session three was a julienne mix for a quick stir-fry — carrots, zucchini, and yellow squash with the fine tooth blade. The julienne strands were clean, not shredded, and cooked in the same pan in the same time without some turning golden while others stayed raw.
The one consistent friction point: very round produce like onions or apples needs a flat cut on the bottom to sit stably on the mandolin. Without that stabilization, the round shape lets the piece wobble toward the edge of the blade. Cutting a thin slice off the stabilization side first solves it, but it's an extra step that affects flow.

Verdict & price check
The Benriner Super Slicer is the mandolin most home cooks should actually buy. Four sharp blades, a working thickness dial, and a safety guard that does its job — all for under $40. It won't replace a professional mandoline for a restaurant kitchen, but for weekly meal prep and weeknight variety, it beats pulling out a cutting board and knife every time.
