As I read into the Anglo Saxon book, there is a description on how sword blades are forged from small pieces of iron ore, flattened, stacked and twisted to get rid of the slag weakness. This creates a surface herringbone fine structure. Hence my earlier comment on it being merely etched decoration is wrong.
See this page below and diagram.
