Watering on a tulwar blade

[Jens Nordlunde]

There are no traces of a bigger decoration on either side of the blade, so I doubt that can be the reason.
In one of my books, I have unfortunately forgotten which, but it could be in the one by Francois Bernier, Travels in the Mogul Empire A.D. 1656-1668, the author writes, that customers can look in books with many different designs before they order a hilt. This could indicate that it was the goldsmith who made the hatching for koftgari, but it does not mean that he did, maybe he had the hatching made at the blade smith’ after his instructions – I will have to go on reading.
