Maybe they are not physical manifestations persay, would you call what urahara done a physical manifestation? I wouldnt think so, it brings the esscense of the Zanpakuto there, but its not the actual thing. Its made of card, like a host. or whatever. I would call it, a projection, of their soul maybe? They project themselves, like a hologram that you can interact with. But they are far from physical, i think they are just floating swords in all fairness. Or maybe they are what Ichigo and Renji perceive them to be?
