A citrus zester is a kitchen tool used to produce very fine, almost thread-like strips of citrus zest for use as an ingredient, and as a garnish for dishes and beverages.
Ginger graters are made from ceramic or porcelain, or less commonly, carved from bamboo. The teeth on them is quite different from that on other graters: it’s because ginger is so fibrous and so hard to grate.
A grater is a surface with sharp, raised teeth or ridges on it to grate or shred firm-textured foods.
Microplane® is the brandname of citrus zester which looks somewhat like a long wood rasp. It produces fluffy shreds of citrus zest very fast.
