Make easy work of onions, nuts and more with the Oxo Chopper. Press the soft knob and the blades rotate for even chopping. Chop ingredients in the enclosed cup with its soft, non-slip base, or remove the base and chop directly on a cutting board. A tab rotates within the cup to prevent food from accumulating on the side walls. The entire blade cartridge can be removed from the Chopper by simply unscrewing it, making cleaning easy. Includes a spoon for scooping so therea€™s no need to leave your hands smelling like onions or garlic. The Oxo chopper is dishwasher safe.
