Guisarme

A guisarme (sometimes gisarme, giserne or bisarme) is a polearm used in Europe primarily between 1000 and 1400. Its origin is likely Germanic, from the Old High German getīsarn, literally "weeding iron". Like many medieval polearms, the exact early form of the weapon is hard to define from literary references, and the identification of surviving weapons can be speculative.
