Tessaiga's sheath

Tessaiga's sheath is a scabbard powerful enough to contain the powers of the Tessaiga itself. As such, it is capable of projecting barriers, which Inuyasha uses on multiple occasions to save his life. The sheath is also capable of summoning the Tessaiga from a distance. It was made by Tōtōsai from the boughs of the tree yōkai Bokusenō.
