A goedendag ( in Dutch; also rendered godendac, godendard, godendart, and sometimes conflated with the related plançon) was a weapon originally used by the militias of Medieval Flanders in the 14th century, notably during the Franco-Flemish War. The goedendag was essentially a combination of a club with a spear. Its body was a wooden staff roughly 90 cm to 150 cm (3 to 5 feet) long with a diameter of roughly 5 cm to 10 cm (2 to 4 inches). It was wider at one end, and at this end a sharp metal spike was inserted by a tang.
