One can never post too many wootz pictures and shame on anyone who thinks such a thing!
Circular distortions, such as you picture, are not an uncommon feature in wootz blades but seem to show up in better quality examples. I define better quality as higher levels of activity(circular distortions, meandering lines, etc.), higher contrast and generally tend to be of a more sophisticated level of grind and polish. As you state, the ladder and rose pattern is created through a manual manipulation of the wootz bar and therefore tends to have regularity to its spacing, position between ladder rungs, etc.
Beautiful example. Thanks for sharing!
