One end can be released to extend the chain in order to hit an opponent. dependent upon region, construction and intended use. Other names in use include dai chui, flying hammer, or dragon's fist. It belongs to the broader classes of flail and chain weapons.
There are two types of meteor hammers: a double-headed version and a single-headed version.
The double-headed meteor hammer is typically 2–3 meters in length (traditionally 2 meters) with a spherical head on each end. While the ends of the meteor hammer can be heavier than a rope dart head, the difference in weight is not normally great. Some meteor hammer versions have heads which are much lighter than most rope dart heads. The lighter versions of this weapon are typically used for practice and for modern wu shu displays since they are faster and less dangerous.
The single-headed version of this weapon is used in a similar manner to the rope dart in that it is a long reach weapon with a single head. The main difference between the headed meteor hammer and a rope spear is that traditionally the meteor hammer has an end shaped similar to an egg or melon. The single end can traditionally weigh up to 3 kg and is attached to a rope that can be 6 meters (20 ft) in length (in contrast a rope dart is typically 3.6 meters long). Because of these traits, a single headed meteor hammer can be a very effective weapon, despite being very difficult to control. The weapon could attack in multiple directions and even in an arching pattern when engaged in formation attacks. This weapon would be tossed up and over an enemy formation to hit troops not yet engaged in the head.
