Glaive
The Glaive (Glafe) was an axe like polearm with a broad flat blade with an arched cutting edge narrowing to a point. Used mainly as a herald's weapon, after the middle of the 16th century the Glaive became purely a decorative weapon. The blunt side of the blade often had a hook or a crescent shaped smaller blade and the base of blade also had two triangular blades to help prevent an enemies weapon sliding off the main blade and up the shaft.
