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 any opposition, whether it be spiritual, or physical.

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