Maybe Orochimaru could summon the sword back to him. There was this time when he stabbed Sai with a sword, then the sword turned into a snake and went back to him. If the sword that was used to stab Sai is Kusanagi sword or if the Kusanagi has the characteristic of turning into a snake as well, then obviously he could summon it back to him.
