Viking blades bearing Ulfberht inscriptions have been found across Europe, Scandinavia, Britain and Russia. It is held that the name is either that of a long-lived family manufactory or a group of closely associated workshops, the possible origin being Frankland, in the area of modern Solingen. One hundred and twenty-two examples were identified by Alfred Geibig in his highly detailed survey published in 1991
For a synopsis of Geibig's work and a further analytical study of the subject see Michael R. Gorman, Ulfberht: Innovation and Imitation in Early Medieval Swords, catalogue of the Sixteenth Park Lane Arms Fair, London, February 1999.
The present sword is classifiable as Petersen type X
