My Kyocera Mandolinemakes cutting multiple onions a walk in the park. The blade adjusts to 4 widths, giving you the flexibility of slicing super thin firmer produce, or thicker slices (typically for softer or more delicate fleshy fruits or veggies). I wash mine in the dishwasher (top rack), and use it daily to slice veggies, potatoes, apples and other goodies. It takes up so little space in a drawer, but also can be hung on a hook or peg board. From chips to dippers, this is one of my favorite things! For $17 on Amazon, it's a game changer. To order one CLICK HERE.
