12th-13th century. 17 1/2" length. Heavy forged iron with clipped point blade, like a large seax and undoubtedly influenced by that earlier weapon. The tip with integral hook for pulling down a mounted adversary. Very rare form, clearly evolutionary in the development of the halberd as well as the fully developed glaive of the Renaissance. See Stone p.248. This form in use from the first through ninth crusades. Ex: Chateau Heeswijk Armory.
