Method
Curved knives such as this one were used, in the past, for some kinds of amputations.
The first step is ligating the supplying artery and vein, to prevent hemorrhage (bleeding). The muscles are transected, and finally the bone is sawed through with an oscillating saw. Sharp and rough edges of the bone(s) are filed down, skin and muscle flaps are then transposed over the stump, occasionally with the insertion of elements to attach a prosthesis.
