One thing that's always confused me about Ichigo's Zanpakuto was that either Byakuya or Urahara (I don't remember who at the moment) stated that Ichigo's original Zanpakuto, which Byakuya snapped like a twig, was made from Rukia's stolen reiryoku... but after Byakuya purged her power from him, when Ichigo awakened his own Soul Reaper powers he was holding the exact same snapped sword, which Urahara proceeded to dice down to its hilt until Ichigo activated his Shikai.

Granted, the nature of Zanpakuto has undergone a couple of retcons since the first chapters, but even so it's a bit confusing.
