Sara, here is a crap pic I just shot to show you the graters I use. Really basic stuff, the kind you can pick up at Walmart or something. The one in the foreground, though, I bought for .99 cents at a Japanese food store (I believe they use it to shave wasabi and radish or something), and it gives me a pretty fine powder. The others produce bigger, grainier pieces (can you see the clumped up clay on parts of he graters? LOL!). I go into kitchen shops whenever I see them, and they have some gorgeous yet costlier graters and planers. I've nearly broken down and bought some on occassion, but I always change my mind in the end because I think the ones I have serve my purposes enough :-).
