"The single edged, curved bladed dao, or saber, dates from around the 13th -14th centuries. The curved blade was introduced to China as a result of the Mongol invasions, and its popularity is shown by the fact that it had eclipsed the straight bladed jian as the dominant military side arm from the 15th century onward. The "willow leaf" (liu ye) dao is an old blade pattern which displays considerable variety in shape and dimensions. Generally averaging about 26 -30 inches in length, its blade curves gently throughout its entire length. The blade may remain almost the same width for its whole length, or it may gradually taper towards the point. It often had a sharpened back edge, indicating a higher degree of sophistication in its technical usage. A military issue weapon, its blade shape, size, types of fittings and ornamentation were regulated by documented imperial specifications. Each blade size was intended for a specific military application. For example, a relatively short dao might be used by vanguard troops scaling walls on climbing ladders, where a long, difficult to draw sword would be awkward to put into use. The willow leaf saber was almost completely eclipsed by the "oxtail" blade pattern made for civilian use by the mid 19th century."
