How it works: Razor sharp knives cut the connective tissues that make meat tough. Tiny "heat channels" are created without changing the shape or appearance of the meat, resulting in (1) faster penetration of marinades, (2) even cooking throughout the meat and (3) significantly reduced cooking times (up to 40%). As a result, your meat will be consistently tender and retain more of its natural juices. Dishwasher safe. Jaccard
