What is a tachi sword?
A tachi is a traditional Japanese curved sword that predates the katana. Developed during the Koto period (roughly 900–1596), the tachi was designed for mounted cavalry — its deep curvature and longer blade made it effective for downward strikes from horseback. Unlike the katana, which is worn edge-up through the belt, the tachi was suspended edge-down from the waist by cords. Today the tachi is valued by collectors for its historical significance and elegant blade profile.
