Cuts of steak can be broken down into three sections. Starting on the upper back and moving down to the mid-back you have the rib, the short loin and the sirloin. The rib contains cuts such as the Rib Roast, the Rib-eye Steak and the back ribs. This is the least tender section of the three. The short loin produces the T-bone, Top Loin Steak, Tenderloin and the Porterhouse. The Sirloin gives the Sirloin Steak, and the Top Sirloin.
