Ancient Sword That Came From The Future? The Ulfberhts

A group of medieval swords found within Europe, dating between the 9th through 11th centuries, the blades faces are inlaid with the inscription “Ulfberht,” with a cross on either side. The word turns out to have been a Frankish personal name, it somehow became the basis logo, a trademark of sorts, used by multiple blade smiths for several centuries, in their impressive attempts to make the hardest, most impressive swords of the era.

About 100 to 170 Ulfberht swords are known to exist, yet the origins of the name remains somewhat of an enigma, however, we dare to postulate that the name may have originated with this sword in particular… A sword which these blade smiths may have been attempting to replicate and indeed figure out how it was made.

A NOVA, National Geographic documentary titled “Secrets of the Viking Sword”, which first aired in 2012, actually took a look at this enigmatic sword’s metallurgic composition…The Ulfberht sword has almost no slag content within its composition, and it has a carbon content three times that of other metals from the time, carbon found to be a great addition in strengthening steel, creating a metal known as “crucible steel.”


A critical discovery, something which made England famous some 800 years after this swords creation.In the process of forging iron, the ore must be heated to 3,000 degrees Fahrenheit.

This will bring the metal to a liquid molten state, allowing blacksmith to remove impurities called “slag.However, 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.
