It cannot be said that the Ulfberht weapons revolutionized swordplay, as they were scarcely available and it took centuries before any comparable swords were produced. However, they certainly made an impact between the 9th and 11th centuries, with around 170 of these swords known to historians.
The Vikings that wielded the Ulfberht swords held a substantial advantage over their foes. Ulfberht swords were better in every department than the most common swords. Giving the user more guile and power, the brand was also notable for being shatter-resistant in a time when most swords rarely lasted.
The brand is exactly the right word for the Ulfberht sword; the weapons bore the name Ulfberht on the blade, with that name becoming synonymous with quality of a near-mythical level.
This prestige ensured that the Ulfberht swords were the preserve of Viking noblemen blessed with vast wealth. As with modern brands, imitations of Ulfberhts were made that were indistinguishable from the real swords.
Unfortunately, the consequences of buying a fake sword may have been found out in a more uncomfortable fashion than when discovering a piece of designer clothing is counterfeit.
Vikings became feared across Europe for their strength as warriors, with the power of the Ulfberht swords a contributing factor.
In particular, Vikings were renowned for their aptitude as an invading force, deploying ‘shock-and-awe’ tactics that denied domestic forces the chance to assemble and prepare. Europe’s armies responded by improving their organization, thereby ending the reign of dominance for the Vikings.
Having considerable standing armies negates much of the power of a weapon like the Ulfberht sword. A deadly sword is no good if there are enemies swarming on all sides.
Swords were also expensive to produce, with the Ulfberht sword particularly so. It is impressive that the Vikings managed to acquire as many as they did, with the technology needed for mass production not readily available until the Industrial Revolution.
