Evidence for the length of insular Anglo-Saxon spears is limited, but based on grave finds it has been estimated that they ranged in length from , compared to continental examples found at
Nydam Mose in Denmark which range from long. Although shorter and lighter spears with smaller heads were generally preferred for use as javelins, an exception was the barbed
angon, one of which was found at
Abingdon with a head measuring . The barbs were designed to lodge in an opponent's shield (or body) so that it could not be removed and the long iron shank prevented the head from being cut from the shaft. The
angon was likely designed to disable enemy shields, thus leaving combatants vulnerable, and disrupting enemy formations. The shaft may sometimes have been decorated or painted, and iron or bronze rings were sometimes fitted onto it which may have marked the
center of balance and thus the best place to hold the weapon. ==Use==
