The Liston Amputation Knife is specifically designed for surgical amputation procedures, and its primary function is to cut through large, dense muscles. The knife features a long, sharp blade that allows the surgeon to make deep, clean cuts, which is essential during amputation to ensure that tissues are severed efficiently and that blood loss is minimized.

While the knife may also impact blood vessels and skin during use, its design and purpose focus mainly on cutting through substantial muscle tissue. This capability is crucial in an amputation, where clear separation of muscle from bone is necessary for a successful outcome. Understanding the unique design and intended use of the Liston Amputation Knife highlights its significance in surgical procedures.
