Legendary Saga of St. Olaf, the kingsbane Thorir Hund is said to have worn a tunic made from reindeer fur, enchanted by "Finns" (Sámi), defending him from sword blows. The tunic is described as "magically" enhanced which may indicate that it may not represent a typical example of such a garment. Leather clothing does, however, occasionally turn up in archaeological finds, and would have offered some degree of protection in combat. All in all, the case for non-metal forms of armour remains inconclusive. It is likely that the average Viking fought whilst wearing ordinary clothing, with the shield as the only form of protection. Foreign origins of Viking arms and armour Foreign-made, specifically Frankish, weapons and armour played a special role in Norse society. Norsemen attained them either through trade (an extension of gift-giving in Norse society) or as plunder. Therefore, their possession and display by any individual would signify their station in the social hierarchy and any political allegiances they had. One example of an exchange of weapons between the Franks and the Vikings occurred in 795 when Charlemagne exchanged weapons with the Anglo-Saxon king Offa of Mercia. Scandinavian affinity towards foreign arms and armour during the Viking Age had an eminently practical aspect. Norse weapon designs were obsolete and sources of iron within Scandinavia were of poor quality. Frankish swords like the VLFBERHT had a higher carbon content (making them more durable) and their design was much more manoeuvrable compared to Scandinavian-produced swords. Although smaller weapons like daggers, knives, and arrowheads could be manufactured in Scandinavia, the best swords and spearheads were undoubtedly imported. Many of the most important Viking weapons were highly ornate—decorated lavishly with gold and silver. Weapons adorned as such served large religious and social functions. These precious metals were not produced in Scandinavia and they too would have been imported. Once in Scandinavia, the precious metals would have been inlaid in the pommels and blades of weapons creating geometric patterns, depictions of animals, and (later) Christian symbols. Vikings also used foreign armour. According to Heimskringla, one hundred Vikings appeared "in coats of ring-mail, and in foreign helmets" at the Battle of Nesjar in 1016. During the mid-9th century, there was an influx of these high-quality weapons into Scandinavia, and Frankish arms became the standard for all Vikings. As Ahmad ibn Fadlan observed in his account of his journey to Russia, every Viking carried a
