Yata Mirror

The Yata Mirror was an ethereal shield wielded by the left arm of Itachi's Susanoo. It is said to be endowed with all nature transformations and as such changes its own characteristics to completely negate anything opposing the user, whether it be spiritual, or physical.

Zetsu claimed that this, combined with the Sword of Totsuka held in its right hand, essentially made Itachi's Susanoo invincible.
