Possibly Chinese Pichok?

[ariel]

I have yet to see Uzbeki Р’chak or Tajiki Pichok with such massive blade. Hieroglyphs establish Uighur origin. And, yes, Yangisar.

I wonder whether knife manufacture is still present there: Uighurs are Muslims and were not very fond of total Chinese control. There were multiple acts if killing local Chinese functionaries, and currently a good chunk of Uighurs are in concentration camps and “ re-education camps” (which is the same). Ownership of “sharpies” is severely controlled. Google : “Authorities in Xinjiang Require Special Permits to Buy Kitchen Knives’’”. Knives are marked with laser—etched QR codes.
