From 13th Century Korea, The Galgorichang Spear was a form of Anti-Cavalry Pole Arm/Spear. It evolved into several different type of “Heads” as a result. The most common form, resembled a Crescent-shaped Axe Head mounted on a 8 to 10-foot wooden Pole. The purpose of the weapon was to both “knock off” or pull an enemy rider down (by snaring his Armor). Later versions also added a single curved Hook (making The Galcorichang similar with the European Halberd Pole Arm).
