i think in all periods in history; in all places and culture, for both warriors and common men; there was a great reluctance to let others handle one's weapon. samurai do not lightly forgive someone who touches their swords, even by the scabbard. trained servants handle warriors' weapons following strict rules. crowds are incovenient to a samurai as commoners could easily brush against their weapons.
even in the lord of the rings part 2, the members of the company were very reluctant to leave their weapons at the entrance to theoden's house, "death will come to any man who draws anduril save elendil's heir!"
