Viking Sword Made With Technology From the Future

Mysterious Viking Sword Made With Technology From the Future?

By Tara MacIsaac , Epoch Times

The Viking sword Ulfberht was made of metal so pure it baffled archaeologists. It was thought the technology to forge such metal was not invented for another 800 or more years, during the Industrial Revolution.

About 170 Ulfberhts have been found, dating from 800 to 1,000 A.D. A NOVA, National Geographic documentary titled “Secrets of the Viking Sword”, first aired in 2012, took a look at the enigmatic sword’s metallurgic composition.

In the process of forging iron, the ore must be heated to 3,000 degrees Fahrenheit to liquify, allowing the blacksmith to remove the impurities (called “slag”). Carbon is also mixed in to make the brittle iron stronger. Medieval technology did not allow iron to be heated to such a high temperature, thus the slag was removed by pounding it out, a far less effective method.

The Ulfberht, however, has almost no slag, and it has a carbon content three times that of other metals from the time. It was made of a metal called “crucible steel.”

It was thought that the furnaces invented during the industrial revolution were the first tools for heating iron to this extent.

Modern blacksmith Richard Furrer of Wisconsin spoke to NOVA about the difficulties of making such a sword. Furrer is described in the documentary as one of the few people on the planet who has the skills needed to try to reproduce the Ulfberht.

“To do it right, it is the most complicated thing I know how to make,” he said.

He commented on how the Ulfberht maker would have been regarded as possessing magical powers. “To be able to make a weapon from dirt is a pretty powerful thing,” he said. But, to make a weapon that could bend without breaking, stay so sharp, and weigh so little would be regarded as supernatural.

Furrer spent days of continuous, painstaking work forging a similar sword. He used medieval technology, though he used it in a way never before suspected. The tiniest flaw or mistake could have turned the sword into a piece of scrap metal. He seemed to declare his success at the end with more relief than joy.  

It is possible that the material and the know-how came from the Middle East. The Volga trade route between the Viking settlements and the Middle East opened at the same time the first Ulfberhts appeared and closed when the last Ulfberhts were produced.

But...what was the technique??

NOVA has a video for sale, "SECRETS OF THE VIKING SWORD," showing how Furrer made the sword, using technology available at the time.

Really interesting, and prompted me to look into it further. Found the idea of over 170 'Ulfberhts' being found the most interesting, suggesting a whole industry. Also the idea that this sort of 'trade mark' was a mark of quality, a sort of 'designer brand' also prompting the subsequent production of 'fakes.'

The discovery of such advanced metal work so early on is also very interesting. I am constantly in awe of the craftsmanship, artistry and knowledge of our forebears.

It is one of my ambitions to one day be able to have-a-go at forging a sword. Doubtless when I do, I will develop an even greater understanding of the skills involved.

Thanks for the article.
