The katana sword was invented in the 15th century.  The name of the man who made it was Amakuni Yasutsuna. Before the katana was made, they used double-edged swords known as chokuto, but they weren’t too durable, so Amakuni and his son took an oath to make the best sword they could.

They used iron sand ore and smelted it to steel.  They prayed to the Shinto gods then the son had a dream where he saw a 1 sided edged sword.  So he and his father spent 31 days (1 month). When he made them, he handed them to the emperor, and the emperor then handed them to his soldiers.  His soldiers came back with no swords broken.  Amakuni Yasutsuna was recognized as a hero to his nation.
