The spear was the most common weapon of the Scandinavian peasant class. Throwing spears were constantly used by the warrior class; despite popular belief, it was also the principal weapon of the Viking warrior, an apt fit to their formations and tactics. They consisted of metal heads with a blade and a hollow shaft, mounted on wooden shafts of two to three metres in length, and were typically made from ash wood. The spear heads could measure between twenty and sixty centimetres with a tendency towards longer heads in the later Viking Age. Spear heads with wings are called krókspjót (hooked spear) in the sagas. Some larger-headed spears were called höggspjót (chopping spear) and could also be used for cutting. The barbed throwing spears were often less decorated than the ostentatious thrusting spears, as the throwing spears were often lost in battle.
The spear was used both as a throwing weapon and as a thrusting weapon, although there was some specialization in design. Lighter, narrower spearheads were made for throwing; heavier broader ones, for stabbing. Most evidence indicates that they were used in one hand. Limited evidence from a saga indicates that they may have been used with two hands, but not in battle. The head was held in place with a pin, which saga characters occasionally pull out to prevent a foe from re-using the weapon.
Compared to a sword, the spear can be made with inferior steel and far less metal overall. This made the weapon cheaper and probably within the capability of a common blacksmith to produce. Despite this, the spear held great cultural significance to the Viking warrior, as the primary weapon of Odin, the king of the Norse gods and the god of warfare, was the spear Gungnir. The Eyrbyggja saga alludes that a customary start to a battle included throwing a spear right over the enemy army to claim it for Odin. Possibly due to its cultural significance, pattern welded blades are common in spear heads, and the sockets were often decorated with silver inlaid patterns.
