I think that is the fullered flat of a sword blade, so a couple inches or more across. The pattern exhibits at scales you'd need magnification to see all the way up to bands a mm across. I have a blade that was created using one of the reproduction processes. I have heard some say it is simply a very specific type of alloy banding.
