There were two Koebi Jitte. They were given by the Crab Clan to the ronin Koebi when he first swore fealty to them. One was carried by the sole remaining member of the Koebi family, Hida Ryhodotsu, and the other was being sought by Ryhodotsu since it was lost in the storm that destroyed his family in 1123. Both were crafted of dark black steel and studded with jade, and thought to be unbreakable.
