This attachment performs the cutting and shredding duties your food processor might : select the proper cone, slip it into the plastic housing, and attach all to your stand mixer’s hub with a metal shaft. You can shred potatoes, onions, nuts, and chocolate, or slice vegetables for cooking or munching. While it adds versatility to your mixer, the unit is cumbersome to disassemble–more so than KitchenAid’s other nifty attachments–and its several parts make it difficult to store. Still, it’s easier on your arms than manual slicing and shredding, especially for large quantities, and all parts are dishwasher-safe. –Betsy Danheim
