Record summary
Ulfberht swords are a group of high-status medieval blades marked with variants of the inscription +VLFBERH+T. Metallurgical studies have identified examples made from unusually high-quality crucible steel, prompting discussion of production centers, trade routes and technological transfer. The inscription is not a simple guarantee of one maker: spelling, quality and chronology vary, and some blades appear to be imitations. They matter for comparing archaeological evidence of craft specialization with modern “lost technology” narratives. The technological achievement is real, but claims of a single secret workshop or mysterious process exceed current evidence.
