in a bag, over the shoulder, with a more conventional weapon in a sheath if you need a weapon in a hurry.
IMO, weapons like that are "display" weapons, meant to let the user show mastery of a certian move or skill (eg disarming, trapping, etc), and were intended for "real" combat. this is not the same as them never being used for real combat, it's just i think that wasn;t the point of ther weapon.
