I assume the Brit term refers to repeated folding and forge-welding -- akin to Damascus steel. If that's the case, the survival of the sword is really special -- because such multilayer metals are commonly victimized by corrosion delamination.

And considering the Angles, Saxons, and Jutes conquered much of Britain, they left very little behind. Like other groups in other places, their burials are pretty much it, and those are little found.
Yes the term does refer to repeated folding, but also twisting length ways of the rods before being hammered back together.
There are several tv shows on this that may be on YouTube by now.
