Ulfberht is a name given to unique Viking swords used in Scandinavia in the 1000s. The unique high-quality steel they incorporated remained unparalleled until the Industrial Revolution. 171 such swords have been found so far but only a few of these have been proven to be authentic Ulfberht swords. The earliest Ulfberhts date from circa 850.
