Hello chregu

Congratulations! Magnificent knife.
I asked for my friend's help in translating. Here is what he writes:
Well known saying for Turkish (Seljuk) thinker and statesman Ahi Evran:
Gelen gelsun saadetle, Giden getsun selametle.
كلان كلسون سعادلة، كيدن كيتسون سلامتلة.
Translation: Everyone is wellcomed to be one of us, however, we welkcome his leaving us if he asks to leave.

Hello Turkoman. khan

thank you very much for your quick answer.
so the knife would have to come from the area of ​​today's Türkiye? from around the middle of the 19th century? what do you think?

Hello Chregu

I think this is the center of the Ottoman Empire (today's Turkey) and I think this is the 18th century

Hello Turkoman.khan

Thanks a lot for your help
I am fascinated by the brown jade handle, which is rarely seen. I still have a curved dagger with an identical handle. but this is currently in an exhibition.
