Meat Grinder
A meat grinder or meat mincer is a culinary tool for grinding meat. Several varieties of the tool are available, although most people conjure the image of a hand-powered grinder which is cranked.
Most meat grinders function by forcing the meat against and through small holes as it is cut.
