Microplane makes the very best graters for spices, citrus zests, chocolate and other such things. They are the sharpest, easiest to use, and most durable grater of this type that we've come across.
The Master Series Fine Grater is the perfect kitchen tool for grating a variety of hard spices like cinnamon, dried ginger and turmeric pieces, and nutmeg. It's also excellent for citrus peel, fresh ginger, parmesan cheese and almost anything else. The Master Series is perhaps the most stylish of all Microplanes, with a handle of Kentucky walnut. This grater is not dishwasher-safe -- hand wash only.
