The OXO Steel Chef's Mandoline offers a variety of cutting options, including straight and wavy blades, and built-in julienne and French fry blades. Turn the knob to adjust for desired thickness from 1-9mm in 0.5mm increments. The textured slicing deck helps keep food from slipping. Safety hand guard keeps your fingers away from the blades, and non-slip feet fold in for compact storage. Mandoline body and food holder are top rack dishwasher safe. Hand wash blades.
