Heavy medieval polearm. Literally, "beak of the raven" (
IIRC, any french speakers out there can
/msg me to correct this), the
business end was used to punch holes in
plate mail armor (and the soft gushy bodies concealed therewith). This
weapon was about eight feet long, with both a straight point and a long, hooked blade stemming from the top. Hence the name, I suppose. This weapon was also used to
forcefully dismount horseback riding
soldiers, though much more appropriate
weapons existed to do this as well.
