The Microplane Mini Zester features the same high-quality zester blade as full-size Microplane graters and zesters. This mini grater, however, fits in your pocket. Take it with you for grating on the go. Microplane graters and zesters feature tiny razor-like edges formed by a process called photo-etching in which holes are dissolved with a chemical. A Microplane grater edge finely slices instead of tearing or shredding. Superb, top-of-the-line Microplane graters are safe and easy to use. Dishwasher safe. 18/8 stainless steel blades made in USA.
