Just learned about the Sword Brothers
from the In Our Time podcast.
Disappointingly, instead of being fun, amusing characters, they were a group of brutal thugs, more like Blackwater than the comical Round Table that I imagined. If you think about it, though, swords were dangerous serious shit back then. If you heard of some Assault Rifle Brothers, you'd probably imagine some fucked up militia idiots, and you'd probably be right.
