The Gichang is a Korean weapon which is first described in the Muyesinbo, a Korean martial arts manual published in 1759. It later also found its way into the Muyedobotongji (1791). The weapon is, basically, a spear with a flag attached to the pole. The gichang is also called danchang (단창), which means 'short spear'. It would typically be around 2.75 metres long. The blade measured about 23 centimetres in length. These spears were generally used for ceremonial or escort purposes.
