We all know this common trope in fantasy that expert swordmen and heroes wear their swords sheathed on their backs.
Question is: how?!
I do own a longsword, blade length about 30 inches. The typical Katana blade seems to be about the same length. The average man's arm is 25 inches, probably used to be shorter back in the days as people used to be shorter.
Thus, no chance that it is feasible to draw or even resheath a longsword (European or Asian or whatever make) which is strapped to our backs and people seem to agree that this was used for carrying it, if at all, not for fighting....or am missing something here?
