A Parrying Dagger
This parrying dagger is a small handheld weapon used in the late European Middle Ages and early Renaissance. These weapons were used in conjunction with a single-handed sword. During a battle, the dagger is used to move the opponents’ sword blade away, allowing the attacker to strike with their own sword. Most left-hand parrying daggers were abandoned except in areas of the world like Spain and southern Italy where these daggers remained fairly popular well into the 18th century.
