I agree... Kakashi will own that sword...Kakashi could work that sword better than Zabuza could. With the sharingan, his speed and lightning element he could go crazy.
i was thinking of that just now lolSomeone said this in another thread and i keep thinking about it: Can anyone else Naruto getting the sword, either as a gift from Kakashi to remember Haku and Zabuza (first mission and opponents) or when kakashi dies, which could be during this war or in 20 naruto years, but i kinda like the idea of Sasuke and Naruto having a bit of a sword fight during their next battle!
