Grater (Oroshigane)

A grater is mainly used in sushi to prepare condiments. These include wasabi, ginger, and daikon radish. With the exception of wasabi a metallic grater is used to grate the root, or vegetable. The wasabi requires a grater with finer teeth so it can release the compounds that have anti-bacterial properties, and the strong spicy taste as well. The wasabi uses a grater made with shark skin.
