The tomahawk steak is a bone-in ribeye steak. It is taken from the rib section, with the large rib bone still attached. Its appearance resembles that of a tomahawk ax. Having a bone-in while cooking, will make your meat superiorly moist and tender. This cut is well known for its spectacular marbling and tenderness. The Certified Angus Beef© standards are more selective than USDA Choice and Prime.
