Thomas Russell Hillier McClatchie, Transactions of the Asiatic Society of Japan (1874)
“ To clash the sheath of one’s sword against that belonging to another person was held to be a grave breach of etiquette;—to turn the sheath in the belt, as though about to draw, was tantamount to a challenge;—while to lay one’s weapon on the floor of a room, and to kick the guard with the foot, in the direction of any one else, was a deadly insult that generally resulted in a combat to the death. ”
