The best cheese grater for 'e is the MouliGrater https://en.m.wikipedia.org/wiki/Mouli_grater . Especially the old ones as new ones have a tendency to be flimsy.

It's great for three reasons:

1 - it's the easiest and fastest grating device for cheese 2 - it's safe. Microplanes are great but it often happened that my cheese got a little bit of finger with it 3 - the texture and taste of the cheese is amazing. I can't explain it but it seems that the strands of cheese are thinner and longer . Whether it's on Parmigiano Reggiano or on old Comté it's just beautiful.

More on topic : never buy pre grated cheese. Or any thing pre-something.
