Also referred to as the corseca, corsèsque, korseke, runka, rawcon, ranseur, and chauve souris (each of these weapons were
very minor variations on the spetum design). The spetum is a polearm weapon similar to the ox-tongue spear, bill, and partisan.
It consisted of a broad blade sharpened on two sides with smaller blades protruding from the left and right of the center blade.
The weapon could be thrust or used for slashing. Many varieties of this weapon existed across Europe, hence the similar shape
but different names for them all.
