Just to demonstrate the quality of the gold inlay, see below side by side two works: On the left is a close up of the Pala blade in discussion. On the right is a section from a mid 19 C. Turkish Jambiya blade:
On the right image one can see the traces of the criss cross scratches on the steel. Also, the sharpness of the letters and the accuracy of the lines in the left image are quite evidence.
As a side note, I wish to add that I consider the inlay on this Jambiya dagger as a good one (every thing is of course relative).
