The GastroMax rotary grater makes grating quick and easy, even for bigger batches. It features four stainless steel grating blades: coarse, medium, fine, and slicer. The coarse blade is perfect for large grating of cheese and root vegetables. The medium grater works well for semi-soft cheeses and vegetables like zucchini. The fine blade is great for grating hard cheeses like Parmesan and chocolate. The slicer is perfect for cutting thin, even slices of vegetables. Hand wash only.
