Kimmo Huosionmaa I always wonder, how the ancient mechanic prosthesis was working, because of the swords from the 16th. century was quite heavy. Also, men who used them were very strong, and the hits were also very powerful, what makes the problems with the prosthesis. If the touch were not strong enough the sword would fly away, and that means that the prosthesis must be made also by using strong material. The machinery inside the prosthesis should also be strong, and when we are thinking, that the hand and fingers have been amputated, would there be some other way to use the fingers than grip and winch, what would use the fingers like pliers. In modern prosthesis is a computer, servo-motors and Bluetooth connection to the human nervous system, and that makes possible to use machine prosthesis, but those equipment have not existed in the 16th. century. So how those men used their prosthesis is an interesting question. German knight Götz von Berlichingen (c.1480-1562), from 16th.
