Guandao in the context of Chinese dragon

A polearm or pole weapon is a close combat weapon in which the main fighting part of the weapon is fitted to the end of a long shaft, typically of wood, extending the user's effective range and striking power. Polearms are predominantly melee weapons, with a subclass of spear-like designs fit for thrusting and/or throwing. Because many polearms were adapted from agricultural implements or other fairly abundant tools, and contained relatively little metal, they were cheap to make and readily available. When belligerents in warfare had a poorer class who could not pay for dedicated military weapons, they would often appropriate tools as cheap weapons. The cost of training was comparatively low, since these conscripted farmers had spent most of their lives using these "weapons" in the fields. This made polearms the favoured weapon of peasant levies and peasant rebellions the world over.

Polearms can be divided into three broad categories: those designed for extended reach and thrusting tactics used in pike square or phalanx combat; those designed to increase leverage (due to hands moving freely on a pole) to maximize angular force (swinging tactics) against cavalry; and those designed for throwing tactics used in skirmish line combat. The hook on weapons such as the halberd was used for pulling or grappling tactics, especially against horsemen. Because of their versatility, high effectiveness and low cost, there were many variants of polearm, which were much-used weapons on the battlefield. Bills, picks, dane axes, spears, glaives, guandaos, pudaos, pikes, poleaxes, halberds, harpoons, sovnyas, tridents, naginatas, bardiches, war scythes, and lances are all varieties of polearms.

A glaive, sometimes spelled as glave, is a type of pole weapon, with a single-edged blade on the end, known for its distinctive design and versatile combat applications. There are many similar polearms such as the war scythe, the Japanese naginata, the Chinese guandao (yanyuedao), the Korean woldo, and the Russian sovnya.

A glaive typically consists of a single-edged blade approximately 45 centimeters long affixed to a pole measuring about 2 meters. The blade is secured in a socket-shaft configuration, akin to an axe head, as opposed to having a tang like a sword or naginata. Some variations of glaive blades were even forged with a small hook on the reverse side to better engage mounted opponents, earning them the name "glaive-guisarmes."

Podao or pudao (Chinese: 朴刀; pinyin: pōdāo) is a Chinese single-edged infantry weapon that is still used primarily for training in various Chinese martial arts. The blade of the weapon is shaped like a Chinese broadsword, but the weapon has a longer handle, usually around one to two meters (about three to six feet) which is circular in cross-section. It looks somewhat similar to the guandao.

The pudao is sometimes called a "horse-cutter sword" since it is speculated to have been used to slice the legs out from under a horse during battle (like the zhanmadao). It is somewhat analogous to the Japanese nagamaki, although the nagamaki sword may have been developed independently. The pudao also resembles the Korean hyeopdo.
