Katana is a sword associated with feudal Japan and more precisely, with the samurai, because only these warriors could carry it. These blades were even claimed to carry their souls. An armourer working for the emperor, named Amakuni Yasutsuna, is considered to have created this weapon after closing himself and his son in a smithy for a month. The secret of its production was passed through generations from then on. Nowadays, if you want to have your own katana sword, you can buy it online, for example on SpecialReplicas.com.
