Like I said earlier B.I., I think that many of the ‘Persian’ blades were made in India – not that I can prove it, it is only a feeling.
I do see how blades could easily be imported into India, even blades made of Indian wootz. If the wootz ingots were exported by sea to Persia or other places, the blades made, and then exported by caravan via the Silk Road to north India – no one would tell from where the ingots came, the only thing the buyer would know was, that the blade came from Persia – so the steel must have been Persian
