What flag is representative of a knight's spur in heraldry?

The mullet, which is a heraldic term for a star with five points, is representative of a knight's spur in heraldry. This association comes from the shape of the spur, which is often depicted as five-pointed, similar to the design of the mullet. In heraldic tradition, symbols and charges on shields and banners are deeply rooted in historical significance and the qualities they represent. The mullet not only signifies nobility but also carries connotations of honor and valor—qualities attributed to knights. The other flags listed, such as the standard, union, and jack, do not specifically relate to the knightly spur or carry the same symbolic meaning connected to knighthood and chivalric ideals.
