The naginata (なぎなた, 薙刀) is one of several varieties of traditionally made Japanese blades (nihonto) in the form of a pole weapon. Naginata were originally used by the samurai class of feudal Japan, as well as by ashigaru (foot soldiers) and sōhei (warrior monks). The naginata is the iconic weapon of the onna-bugeisha-archetype; a type of female warrior belonging to the Japanese nobility.
Naginata for fighting men and warrior monks were ō-naginata. The kind used by women was called ko-naginata. Since the naginata with its pole is heavier and much slower than the Japanese sword, the blade of the ko-naginata was smaller than the battlefield ō-naginata in order to compensate for female lesser height and upper-body strength compared to that of armoured male samurai.
