This excellent rotary cheese grater combines razor-sharp etched blades with a grooved pattern to allow you to grate larger quantities of food with less effort. it's easy to use, has a wide hopper to handle large chunks, and creates ideal shavings of cheese, chocolate, vegetables and nuts. The parmesan drum is ideal for harder foods; it's made with sunburst-shaped holes that when used for parmesan or other hard cheeses or chocolates provides results that are light enough to add to a recipe yet substantial enough to not melt completely on contact when grated onto hot foods. The coarse drum tackles vegetables, most cheeses, and nuts. Unlike conventional graters with punched holes, this grater's tiny razor-like edges are made with a photo-etching process in which holes are dissolved with a chemical, leaving edges that finely shave or slice the food instead of tearing or shredding. A repeated groove pattern is spread evenly across the face of the grating surface, reducing resistance and thereby making grating effortless. Each individual blade is in effect lengthened, so it has a greater cutting surface that comes in contact with food, thereby producing more gratings per stroke. Combined, these features provide an outstanding grating performance, and great results.
