Iron hand of Goetz von Berlichingen, displayed at Jagsthausen Castle.
I'm writing for a character in a medieval fantasy setting, with full plate armor and knights, but guns aren't really a huge thing yet. However, he's lost his left hand just above the wrist (thankfully, he's right-handed). If he was able to get his hand(s?) on a metal prosthetic like the one used by Gotz von Berlichingen, what sorts of options would he have if he wanted to keep fighting? Could he strap a shield to the prosthetic and fight effectively?
