This Extra Coarse grater makes short work of any cheese, soft or hard! The Microplane Master series harkens back to the humble beginnings of these incredible cutting tools. The Kentucky-grown walnut handle is a reminder of how the Microplane originated with wood chisels in the inventor's workshop! The wood is sustainably grown and harvested in the USA. The blades are made from razor sharp "photo-etched" steel to create a cutting surface that is second to none. The 18/8 stainless steel frame provides a robust support for the blade and handle that makes these graters a pleasure to use. Comes with a reusable cover. To maintain your Microplane Master series grater, periodically condition the handle with mineral oil. Hand wash only. Do not soak in water.
