Otherwise known as a knightly sword, an Arming sword was a straight, double-edged sword with a cross-shaped hilt (called a cruciform). Typically around 28-31 inches long. These swords were considerably shorter and lighter than the widely used longsword of the era.
Developed from the Roman spatha swords from the 1st to 6th centuries, these swords were the typical sidearm of Medieval soldiers for nearly a thousand years. Taking on many forms, from the Viking swords of the 9th century to eventually developing into several forms of early modern swords, such as the side-sword and the Rapier.
