Wasn't the Mist busy with infighting during this period, so they may have completely missed his death until later? ehhhh. Perhaps, but the sword just stood there as a gravestone for over three years, and no Hunter-Nin received news of Zabuza being defeated, despite Kakashi/Naruto/Sasuke being referenced by quite a few people as the guy who killed the Demon of the Mist. It's just very difficult to believe.

It was more of a plot error if anything, though It would've been fun to see Suigetsu and Sasuke infiltrate Kiri to steal the sword in the manga instead of just... taking it.
