This (and its child) was tagged with weapon_request. The polearm is called a Ji, it's an ancient Chinese weapon that combined a spear and a dagger-axe (that's the blade perpendicular to the haft). I didn't want to tag it here since such a tag hasn't been used before and trying to distinguish between all the different polearms in the world would be a tagging nightmare (historians don't even agree on a lot of the names and definitions).
