I want to point out that despite this shield being called invincible, Itachi only used it once in the series. He didn't use it against Kirin, for instance. To me it raises questions like, what powers this shield? Is it like a Sage of six paths tool that drains massive amounts of chakra? Because, why else would Itachi use such an ultimate defense so conservatively? Kirin would be a much bigger threat than just some kunai Sasuke threw, even though he used the shield against the Kunai only.

I would expect that if Yata blocked say a meteor and had to become 10km wide, it would proportionally require more chakra to make it that big and deflect the blast.
