text: just a question? can anyone tell me what a cheese grater is made out of and what the manufacturing process of it is? like how is the grater being cast from the material used, the design and the process in general etc.. no website, but they're not cast.  because it's made out of a thin sheet, one can easily ascertain that it was formed from hot-rolled steel and stamped before a bending process.  as far as material, most kitchen items are required to be stainless steel by fda regulations.
