Don't quite know if its been asked/answered/theorized/thought of before. But in Ichigo's fight against Zaraki Kenpachi. Zangetsu magically came back together after it broke... right? In Ichigo's current situation, Ōetsu said something like Ichigo isn't a shinigami because he didn't use one of his Asauchi. Could it be possible (Due to his latent quincy powers) Ichigo, somewhat created his own Zanpakuto. And repaired it. So, only Zangetsu and Ichigo can repair the bankai. Not Ōetsu. Because Ichigo's zanpakuto is not one of Ōetsu's creations. From what we know a normal zanpakuto repairs itself over time. Ichigo's does not do this, it repairs near instantly. (from what I have gathered having a quick flick through Bleach)

On another note. Ichigo's hollow powers seem to stem from Zangetsu (His hollow seems to go back to Zangetsu to go to bed etc). Now, here's where my weird theory gets a little weird. For those who are "up-to-date" with the manga, it will make slightly more sense. Oook. During Ichigo's birth/conception I would guess Isshin was not a shinigami, he had no powers, it would seem he was using them to keep Masaki's hollow in check in what would seem to be her "inner world". Right. The similarities between Ichigo's and Isshin's zanpakuto Engetsu and Zangetsu could be due to the fact that Isshin was using his shinigami powers to contain her hollow. So they may have passed onto Ichigo in some strange way. Quincy absorb Reishi/Reiatsu/Reiryoku stuff right? If thats the case, it would make sense that a foetus Ichigo "absorbed" Isshin's shinigami containing powers alongside the remaining "Hollow Reiatsu" used for hollowification left by White in Masaki. And he obviously gained Quincy powers via blood. (I'm still not 100% on how these powers are passed on to children though, Kubo has been a little bit vague on this stuff seems racial) I'm not sure about this, but maybe Ichigo's powers (besides his quincy powers and fullbring) stem from Zangetsu himself.

Its hard to explain. But Ichigo "made" his own Zanpakuto, but taking some of his fathers Reiatsu (Im not saying that he took Engetsu's powers, but Engetsu used to be an Asauchi, so it had Isshin's soul-like powers in it slightly)

Its super hard to explain. Hopefully someone as nuts as me gets the jist of this weird theory/answer/prediction/question.
