The arming sword was a sword used by the medieval knight, its heyday being from the 1100s to the mid 1500s. The weapon was about a meter long like the Viking sword, but had an elliptical or round pommel and a somewhat larger crossguard, giving it a more cruciform shape, while retaining the standard European double-edged blade. As the longsword and other weapons, became the predominant weapon in the Renaissance, the arming sword, then commonly known as a shortsword, became relegated to the role of a secondary weapon used by a soldier armed with a longsword, polearm, crossbow, or arquebus. A typical example of such a Renaissance arming sword was the Katzbalger.
