The swordsmithing profession is similar to martial art. Each school have different techniques. The techniques of a school would be passed down from the master to his heir and students. All the swords created from them will be considered from the same school unless a student created a new school. The Kunihiro was all created by Horikawa Kunihiro. Mikazuki, Kogitsunemaru, etc. was created by Sanjou Munechika. Akashi was creted by Rai Kuniyuki, who was the founder of the Rai school, Aizen and Hotarumaru were created by Rai Kunitoshi who was the son of Rai Kuniyuki so they are from the same school. You should read the trivia section on each sword page.
