Gourmet editor, Ruth, tells us all about the different graters and why choosing the best grater for each job is very important. The classical grater is called a knuckle bleeder. This is because when you're at the end of the item you're grating, you have to get your hand really close to it and you might scrape your knuckles. The hand grater is easier to use and provides smaller pieces which makes it ideal for most grating jobs. A zester grater is also easy to use and provides more volume than the other graters. So choosing the best grater depends on whether you want more volume, a smaller grating size, or ease of use.
