This discoidal mace head discovered at a site now in North Korea is a unique stone artifact representing the Bronze Age in Korea. Referred to by several different Korean names such as bakwinal dokki (wheel blade axe) and daldokki (stone moon mace), this object is shaped like a disk, is thicker at its center than at its edges, and contains a hole used to fit a handle. This unusual stone artifact is assumed to have been used either as a weapon or a ritual object, or perhaps as a symbol of authority.
