The tachi (太刀, Hiragana: たち ) is a Japanese sword, often said to be more curved and slightly longer than the katana. However, Gilbertson, Oscar Ratti, and Adele Westbrook state that a sword is called a tachi when hung from the obi (belt or sash) with the edge down, and the same sword becomes a katana when worn edge up and thrust through the girdle. The "tachi" style was eventually discarded in favor of the katana.
