Soft cheeses and general grating purposes - OXO box grater with box cup at bottom
I love that I can grate it straight into that little box and know that I have a cup of cheese. I don't have to get a plate or the cutting board dirty and have bits of everything all around me. For harder things like parmesan, nutmeg, zest, ginger, etc. that you tend to want grated smaller, I love my various Microplanes.
