Query: Revolutionary grater

Having used this now for three years, this is the best grater I have ever had the joy of using. To say that it is sharp is an understatement, but it is this very sharpness which makes it perfect for taking off citrus rind and even for grating things as fine as tomato peel. This tool is not to be messed about with, since it will take of layers of skin and fingernails with no question. Slow, and accurate, and it will never fail you. For cleanup you can just throw it in the dishwasher and it's good to go. Don't lose that cover though, since it is essential for storage.
