The OXO Good Grips Hand-Held Mandoline Slicer is a bit different from any slicer you have used before. There is a side-mounted soft knob that allows you to choose one of four settings for the thickness of your slices. It has a clear surface, allowing you to see the cut food and a sturdy, comfortable to grip handle. It comes with a food holder to protect your hands while slicing foods evenly. When not in use, the food holder rests on top to protect the mandoline's blade. The foot permits you to use the mandoline over a bowl, or on a cutting board or counter. The handle, foot, and knob are non-slip, and the whole OXO Good Grips Hand-Held Mandoline Slicer is safe to clean in your dishwasher.
