Accutec graters are razor sharp. With two drums, each with a different coarseness, this rotary grater, made of clear polycarbonate, is all things to all cheeses! The coarse grater drum is perfect for soft cheeses (such as cheddar), hard cheeses, ginger, garlic, and chocolate. The fine grater works well for hard cheeses like parmesan, Romano --even vegetables. Dishwasher safe.
