A ranseur, also called roncone, was a polearm similar to the partisan used in Europe up to the 15th century.
Often thought to be a derivation of the earlier spetum, the head of a ranseur consists of a spear-tip affixed with a cross hilt at its base.
Generally, the hilts do not have a cutting edge, unlike the double-edged partisan.
The spearing function of the weapon is apparent but not always effective against armor of great protection.
The deflection includes the trapping of opponents' weapons in the space below the main blade, where a twist of the shaft can apply pressure from that moment on at long range, and of pulling mounted opponents from the saddle.
