Lang Ya Bang (狼牙棒)

Lang Ya Bang (狼牙棒, lit. 'Wolf's tooth cudgel') was a two-handed spiked cudgel that bore a strong resemblance to English holy water sprinkler as well as Japanese kanabō. It appeared relatively early in China's history, during Spring and Autumn period, although the most recognisable form, that of a wooden club with metal spikes, only arose in popularity during Song period.

There was a prevalent myth that associates Lang Ya Bang with the fearsome Jurchen warriors of the Jin Dynasty. In truth, Jin warriors, being generally mounted, were more feared for another type of blunt instrument known as Qiao Bang (敲棒, lit. 'Knocking cudgel'), which is a one-handed club with octagonal cross-section.

Late Ming period military writer Cheng Zi Yi (程子頤) designed a different Lang Ya Bang with an elongated head and shortened handle. He claimed that his design is better suited on horseback than the original version.
