This is one piece of Wagyu called Tri Tip which is cut from a tri-tip roast, which is a small, triangular cut from the sirloin. It is also known as a triangle steak, bottom sirloin steak, or Santa Maria steak. ... Tri-tip is a good cut of meat because of its rich beef flavor, tender texture, as well as the cheaper price tag than similar steak cuts.
Tri Tip is perfect for slicing thin for hot pot or Japanese style cooking, stir frys or thin steaks on the grill.
