What are the rings on the back of a sword for? You will have to pull the “saya” or sheath away which you have to do if the katana is on the hip as well. But, really, the better question is, can you DRAW a sword from your back? If it’s longer than your reach, then your outstretched arm won’t unsheathe it. So….that is why witchers wear swords on their back. It is heavy as hell, and your left side is always heavier than your right side. Why do Witchers carry swords on their backs? The hilt (rarely called a haft or shaft) of a knife, dagger, sword, or bayonet is its handle, consisting of a guard, grip and pommel.
