Who are the 7 ninja swordsman of the mist?

The seven sWordsman are a group of seven ninja from the hidden mist village.

Each of them carry very powerful sWords that are used as their main source of battle.

Some of the seven sWordsman include Kisame Hoshikage (became a member of the akatsuki-group of evil ninja after leaving mist village-his sWord is called sharkskin). Another is Zabuza (mochia-not sure if this is his last name or not sorry) he also left the mist village but was killed by Kakashi and the other members of team 7- Naruto, Sasuke, and Sakura early in the Naruto series. He is later replaced by a man named Suigestu. He like all the replacement ninja use the same sWord. The replacement process for any members of the seven sWordsman is simply up to the leader and elders of the village. I know that the replacement ninja can be picked very early on in the persons life or later on.
