One of my favorite gadgets is my microplane grater and I have 4 different sizes so I can grate almost anything.  I use it on pretty much a daily basis to grate garlic.  I also use it to grate ginger, lemon zest, chocolate, cheese – either very fine or coarsely grated.  I think it’s best to buy the all stainless steel type so you can put it in the dishwasher.  I have found that plastic in the kitchen always breaks.
