Kodachi

A kodachi(小太刀, こだち), literally translating into "small or short tachi (sword)", is one of the traditionally made Japanese swords (nihontō) used by the samurai class of feudal Japan. Kodachi are from the early Kamakura period (1185–1333) and are in the shape of a tachi. Kodachi are mounted in tachi style but with a length of less than 60 cm.
