Does anyone use this to grate cheese at their shows? I used it tonight for my family and liked it just as well as my old box grater. (Which is really saying something. I always pregrate the cheese for shows and only use the cheese grater for parmesan, nuts or chocolate.) After using it just once, though, I thought I should come here and see if there's any reason this could be an iffy choice for use at a show. Thanks for your input!
