A rondel (pronounced or ) or roundel was a type of stiff-bladed dagger in Europe in the late Middle Ages (from the 14th century onwards), used by a variety of people from merchants to knights. It was worn at the waist and might be used as a utility tool, or worn into battle or a jousting tournament as a side-arm. The blade was typically long and slim, measuring 12 inches (30 cm) or more; the whole dagger might be as long as 20 inches (50 cm).
