It's been a while since I've looked at Albion's "moat sale" page:
http://www.albion-swords.com/moat.htmI had forgotten that they had some "antiqued" swords there. Basically these are complete except for the grip, but they have imperfections and have been left around the shop to rust. They're selling them as a sort of replica artifact.
I think this is great, and thought about doing something like that... except I'd want one made from bloomery iron so that it could be left outside for centuries, like the actual archeological finds.... ... And then I'd be tempted to stash it somewhere in a location that would be unlikely to be discovered for at least a century.
