Liston knife
The Liston knife is a type of knife used in surgical amputation.
The knife was named after Robert Liston a Scottish surgeon noted for his skill and speed in an era prior to anaesthetics, when speed made a difference in terms of pain and survival. The knife was made out of high-quality metal and had a typical blade length of 6–8 inches. Surgical amputation knives came in many styles and changed very much between 1840 and the American Civil War. These changes reflect changes in techniques used by the surgeons and makers of surgical knives during the period.
