I must have been drunk that day. A Zanpakuto is a Shinigami's reiryoku solidified into sword form. Just because a Shinigami dies, does not mean that that physical sword ceases to exist. If I take my blood and freeze it into a sword, that sword would not disappear if I died. The only thing that dies with the Shinigami is the spirit inside of the Zanpakuto.
