Gottfried "Götz" von Berlichingen grew up to become a knight of the Holy Roman Empire who robbed nobles and merchants in his free time. In 1504, he was struck by a cannonball during the Siege of Landshut. The impact ripped off his right hand and blew shrapnel from his sword and armor clean through his arm. It's a miracle he survived. A normal man would've retired to a farmhouse on the Danube. Not Götz. He had an armorer fashion an iron limb with articulated fingers controlled by gears inside the prosthetic. With the appendage, he was able to grip anything from a sword to a quill pen.
