dude I said the following storyline:
My point in saying what I said was that Sasuke had the sword that he has now BEFORE Orochimaru used the OLD Kusunagi to fight Naruto, so why would Orochimaru have the original when he faught Sarutobi THEN change it to Sasuke's so he could train with it while fighting random shinobi THEN change it to the original to fight Naruto THEN change it back for Sasuke to fight Naruto at Orochimaru's hideout??? Doesn't make sense...
Did you read the rest of what I wrote? Changing the hilt of the sword takes not much time and you have no Ida how much time has passed since the battle with Naruto and the arrival at the hideout by Konoha. It's perfectly possible to change the hilt and then train Sasuke, give him the sword and go grab something to eat. Then I said h could also have a jutsu for such occasion, when the sword needed to be re-hilted. Also he and Naruto were using very powerful moves and I said the sword might had the hilt damaged. on the other hand we don't even saw the hilt on that fight (I think...not completely sure) so the sword might have had that hilt for god knows how long.
Thats like the biggest cop out of any excuse...everything could be answered with a conveniently created jutsu, I don't think Orochimaru would bother with a jutsu just the change the hilt of a sword so he could let Sasuke borrow it or whatever. Plus the Naruto-Orochimaru then Naruto-Sasuke fight all happened within one afternoon, I doubt Orochimaru felt the need to change the hilt of his sword soo strongly that he did it right when he got back from his fight...just doesn't seem that important to me that he would do such a thing
