Best graters are made by Microplane, and there are a lot of sizes available.

I agree and the little knuckle guard really helps to keep from grating your knuckles.
But If I am going to grate a lot of cheese I use the fine grating disc on my cuisinart.

I like the graters from Ikea, a two pack with two size graters, two bowls and two tops.

I like the Microplane but I also like the Zyliss. Using the microplane feels better and easier, but the Zyliss works a little faster and you don't wind up with little leftover nubs of cheese.
