Your statement has nothing to do with your question! It doesent matter that BZ dident know about itachis life, however he was alive longer then most people so he definately knew the origins of the tools. But don't worry I see wha this about itachi most likely soloed your fav. /thread.I often hear the argument: Yata can block anything and Totsuka can seal anything because BZ said so. If what I recall is correct, BZ was unaware that Itachi sacrificed his life and was spying on Akatsuki, while Obito/Tobi knew this all along. So why do people assume that he knows everything and that he's right in this particular case?
