1) Persia is known for exporting large quantities of shamshir blades (wootz blades and simple blades) to neighboring countries. This fact is confirmed by historical documents and a large number of undoubtedly Persian blades in India, Arabia and Central Asia.
2) Nothing is known about the fact that Persia would manufacture for export weapons not typical of Persia, but typical of another country. (if there is documentary evidence that proves that I am wrong, I will be very glad to get acquainted with them)
3) In Persia (or Persian craftsmen in Afghanistan), in exceptional cases, they made Khyber knives. These khyber knives are very elegant in the shape of a blade, have a handle that differs from the rough handles of Afghan highbers, their blades are decorated in a completely different technique.
4) The Khyber knife discussed in the subject, by all its external signs, is Afghan. There are no features in it that may indicate that it is made in Persia. In addition to "acid etching."
5) Indeed, in Persia in the 19th century actively used “acid etching” to decorate arms and armor, covering their surface with images and calligraphy. But! As Marius already wrote, the Persians began to do this in the 19th century.
6) The quality of "acid etching" in the early 19th century and at the end of the 19th century is very different. In the early 19th century - with "acid etching" you get deep and clear images. At the end of the 19th century - low-quality images (similar to images on the haber from this topic).
7) In Afghanistan, “acid etching” was not used to decorate blades.
8) How realistic is the historical combination of a typical Afghan Khyber knife and a typical Persian "acid etching"? My personal opinion is that such a combination could not exist in the 19th century. But! Even if you start to fantasize and decide that some Afghan traveled to Persia and for some reason ordered a completely non-standard jewelry on his Khyber knife, then judging by the crude "acid etching", this was done at the very end of the 19th century. That is, to call such a Khyber knife - "old khyber" or, especially, "The oldest dated Khyber I can recall" - is completely wrong.
I hope now I was able to explain what you did not understand
