In Italy we had the world's greatest cheese grater at the apartment. It was an oval plastic box with three oval flat cheese grating lids of different sizes. you put the lid on and grated into the box which held, maybe a cup or so. it was the most convenient cheese grater we have ever seen.
we didn't search for one there because we had to fly Easyjet with weight limits and our stuff for a three month 2-3 season stay -- we were on a strict 'no acquisition' policy.and barely squeaked by
do they sell such graters in France? and if so where? we didn't see anything like it at Dilherrin but then that is not really a store for home kitchens.
