maybe the asauichi (nameless sword, though not sure it is spelled right) is just a sword you carry until you replace it by your own created sword, that would explain why ichigo and zaraki had zampakuto's not real swords before joining the accademy, but I think all swords are equal until you manage to unseal for the first time, which I would think is more like fusing the spirit of your zampakuto to the sword you carry. About Tousen well, probably he took his friend's sword and infused his spirit to that sword, or he just chose to seal his sword like that... the point is the spirit of the zampakuto is just a part of your own spirit, when you die your sword spirit dies with you, that doesn't mean your sword vanishs, it just becomes an empity sword.
^^^I think that is right. Ichigo technically did cheat because of rukia and his sword was so big beacuse the size of the sword is supposed to show whow my reitsu you have and unless you compress you sword like the capts. I also agree with the Zaraki thing his is just probley a real kantana that reitsu has be put in to. To make his sword a Zanpakuto Kenpachi's sword has a name but since he is to arrongant and fighting with is own power he is damageing the sword and himself beacuse the sword and him are in conflict unlike Ichigo and Zangetsu where as they trust in one another and work together.
