The immortals always carry their swords around with them wherever they go in case they get into a fight with another immortal. But how do they carry them in their jackets without getting cut. They don't have any scabbards for them. Duncan ( the main character) usually wears a trench-coat, so he can carry his sword around in it, but what about when he takes it off? He doesn't take his sword out and sometimes he folds up his coat. Does his sword collapse into the handle?
