A wakizashi (脇差) is a traditional Japanese sword with a blade between 12 and 24 inches, similar to but shorter than a katana, together with which it was often worn.
According to traditional samurai law, or Bushido, a wakizashi is used only to commit seppuku (i.e. hara-kiri). After the 16th century it was sometimes used in the off hand with the katana, a technique pioneered by Miyamoto Musashi.
