I would like to make a few observations.
Blades made of layers of steel are correctly called "laminated" and by no meaning, "damascus."
Longitudinal cracks in the spine are signs of "delamination" and they are by no means indication of wootz. These cracks just indicate that the blade was laminated.
When the layers of steel and the finishing of the blade are made so that the layered structure is deliberately revealed, it is called "pattern welded steel" and colloquially "pattern welded damascus" or simply "damascus."
Regarding the blades in the original thread, in my opinion, based solely on the photos, it would be impossible to assert their origin. Even with them in hand, I believe it would be difficult to say whether the blade is of Indian origin or locally made Afghan.
It is true that Northern India was housing several centres that were mass producing and trading blades, but blades were also made in Afghanistan and they bore very similar characteristics to the Indian blades.
