Hi! I expect you heard about this find but I’m rather late in the finding out. I hope you don’t mind me linking the article. http://www.northumberlandgazette.co.uk/news/Unique-castle-sword-found-in.1580775.jp. Fascinating that they have found such a sword. If you do not read the article for any reason, the gist is that a pattern welded sword with six carbon steel rods has been found in Bamburgh. It was ‘micro-welded with flux to join the rods’. Apparently it is rather evolutionary and important, made for an incredibly wealthy individual. One of Uhtred’s perhaps? :) Oh, I enjoyed Sword Song very much and eagerly await the sequel. Thanks.
