Achieve better cooking results from less expensive cuts of meat with the multi-blade hand-held meat tenderizer. It helps reduce cooking time by up to 40 percent and helps meats cook more evenly by reducing shrinkage. Razor sharp knife blades cut through connective tissues that make meat tough. Tiny "heat cannels" are created without changing the shape or appearance of the meat, resulting in faster penetration of marinades, even cooking throughout the meat, and significantly reduced cooking times. Plus, tenderized meat's natural juices are more plentiful. Made of white ABS plastic, the tool measures 5-5/8 by 4-1/8 inches.
