A 2015 Serious Eats review of mandoline slicers, which are used to cut vegetables such as cucumbers, picked two models by OXO and one by Benriner as the best in different categories. By contrast, a Good Housekeeping review of 20 mandoline slicers gave top five-star ratings to models from Zyliss and KitchenAid.
According to the SeriousEats.com comparison, the OXO Good Grips V-Blade and Good Grips Handheld mandoline slicers are the best freestanding and handheld models, respectively. The former, which retails for under $50 as of 2015, has four thickness settings, easily installed battonette and julienne blades, and a robust safety grip. The handheld model, costing under $25, provides three slice-thickness settings and a moderate food gripper. The Benriner Japanese Mandoline Slicer, which sells for under $50, offers a variable-thickness slicer setting that is adjustable up to a quarter-inch.
The GoodHousekeeping.com review of mandoline slicers picked the Zyliss Smart Guard Gourmet Mandoline as the best full-sized model. It features an inverted V-shaped blade that prevents torn edges of slices and a blade guard that engages between slices. The food holder is mounted to the slicer deck, unlike other models, which prevents slips or cuts. The comparison also chose the KitchenAid V-Slicer Hand Held Mandoline as the top portable model. It features three thickness sizes and a compact size for easy transportation.
