A kodachi (小太刀 or こだち ), literally translating into "small or short tachi (sword)", is a Japanese sword that is too long to be considered a dagger but too short to be a long sword. Since this sword was only about 59 cm in length, it did not exceed the blade length limits of non-samurai during the Edo period and could be worn by merchants.
