Minor feats like that do not help it's case. I'm sorry if i was too vague, but that was exactly my point. The one time Itachi used it was when he had nothing left to lose, not even his life. Against Kabuto and Nagato he had a realistic chance to lose yet didn't bother. Against Nagato, he only used Totsuka when the hit was guaranteed. As an Edo, he didn't even have Yata up all the time.

Adding that it's main feat is blocking explosions and a sword, and it's clear that it's neither as powerful as the Databooks suggest, nor as easily accessible as some people make it out to be.

My point for the Totsuka (which has a similar reputation) is similarly that it was only used against someone who didn't see the blow coming and someone who didn't bother dodging. Ergo, based upon how Itachi used it, these weapons cannot possibly be as strong as some people imply them to be.
