The Jamie Oliver Acid Etched Fine and Coarse Grater Set offers you a combined choice of grating options with two razor-sharp blades: use the fine grater on a variety of foods from hard cheeses and chocolates to citrus zests. Use the coarse grater on vegetables, hard cheeses and more. Both graters come with blade covers for safe storage. Jamie says: "These ones will last for years thanks to their super sharp blades."
