I have seen weapons such as this one described as everything from ancient Roman, Celtic and Chinese to medieval and on and on. Though I have been unable to find much in the way of references, I am fairly certain that this spear and others like it are ceremonial polearms from the Qing Dynasty. They are most likely 18th or 19th century. They have crudely decorated brass collars between the socket and blade. This one and the three others I have listed are in good condition with no signs of repair. There is surface rust, but the metal is stable overall. All four of these polearms measure roughly two feet in length. They would make a great addition to any collection and would even look great just hanging on the wall.
Recently I was contacted by a customer who said that he believed that these weapons were 20th century reproductions. As of this writing I do not know if that is correct but will do my best to find out. In the mean time I will advertise them with the caveat that they may be recent production pieces..
