USDA Choice Boneless Beef Sirloin Tip Knuckle, sold as a full case and priced per pound. The sirloin tip knuckle — also known as the "ball tip" or "knuckle" — is a lean, boneless roast cut from the sirloin tip area of the round primal (rear leg). It features a fine-grained texture with good marbling consistent with USDA Choice grading, which represents high-quality beef just below Prime.

USDA Choice grade beef is graded on factors including maturity, texture, and lean color. Choice cuts offer less marbling than Prime but remain very tender, juicy, and flavorful, and are well-suited to dry-heat cooking methods. The knuckle is a versatile cut prized by restaurants, caterers, and foodservice operations for its consistent quality and value.

This cut is well-suited for oven roasting whole, slicing into sirloin tip steaks for pan-searing or grilling, cutting into uniform cubes for kabobs or stir-fry, or grinding into lean ground beef. The full-case format is designed for high-volume food preparation, with an average weight of approximately 13 lb per individual piece or 70 lb for a full case purchase.
