A is a polearm used in feudal Japan. The bisentà  has various descriptions, "a double-edged long sword with a thick truncated blade", "a spear-like weapon with a blade at the end that resembles a scimitar", "a polearm resembling a glaive, with a long, heavy haft and a heavy, curved blade". The bisentà  is said to have been used by ninja and peasants.
Depictions of this weapon can be found in the Chinese military compilations the Wàjëng zÃÂng yào, SÃÂncái tú huì, the WÃÂbèi zhì, and many others, though no artifact representations currently exist of this implement.
