You might want to check out Albion. Nobody else really comes close. Not Del Tin, Windlass, Cas-Hanwei or anybody. And best of all... they’re made in the USA. :-)
They make a nice selection of seriously period-accurate viking swords, along with their other types too. I’ve got the Baron (sharp) and the Liechtenauer (blunt). I also have some Hanwei sharps and blunts, and a couple of Cold Steel sharps. Cold Steel is a little hit and miss on quality. When they’re good they’re really good, but they’ve had some quality issues over the years. They are not particularly historically accurate. Unlike Albion... they go to great lengths to reproduce extremely accurage period pieces, in every way, from design to construction and metallurgy.
