In this case, the triangular dots (or better to say the pits) are completely different from the surface of the file. The surface after filling the pits with gold is completely flat (perhaps this is the result of numerous cleanings). I assume that in the years 1880-1920 no one used this technique for about 100 years, either in Dagestan or in Iran. Those items that I saw personally date back to the 18th century or at the very beginning of the 19th century.
