Preceding the development of The Katana Sword, The Tachi was slightly smaller. Their blades ranged in length from 27 to 31-inches in length. Still encompassing the traditional Japanese Swordmaking techniques, The Tachi was carried (unlike The Katana) – with it's cutting side downward. This resulted in an “upswing lateral cut” unlike the more traditional Katana underhand draw. Designs can be traced to before the 15th Century. The Tachi was extremely popular among Cavalry Troops as their primary weapon.
