Alright, I'm really curious. Apparently, a sword/weapon cannot be restored if it is broken, but that isn't making any sense. Renji's Bankai was completely shattered in his battle against Szayelaporro Granz (Espada 8), yet he was able reuse it at later times. Ikkaku's Bankai broke at the end of his battle with Edrad Liones, yet he never mentioned that it wouldn't recover. How come this rule stating broken Bankais could never recover was only established far into the manga?

Not to mention, the rule doesn't even make sense sometimes. How could you break Kaname Tosen's Bankai, for example, if it just involves complete darkness? Could anyone explain this?
