What is Kodachi in Japanese Katana terminology?
"""Kodachi"" (小太刀) refers to a general term for short swords that have the appearance of a Tachi (long sword). There are no specific rules regarding its dimensions. Examples of Kodachi can be found from the Heian period to the Muromachi period, and they were mainly used as auxiliary swords to the Tachi. The blind swordsman known as ""Toda Seigen"" (戸田勢源) is famous as a master of the Kodachi.
This highlights the versatility of Japanese swords, with different types designed for different purposes. The Kodachi, with its shorter length, would have been easier to handle in certain situations, making it a valuable weapon in the arsenal of a samurai. The fact that it was used as an auxiliary sword to the Tachi also suggests that samurai were prepared for various combat scenarios, demonstrating their strategic thinking and adaptability."
