Thank you Dmitry!!! I knew there was somebody still out there!!!
You truly are a good sort, and you are great at adding pertinant detail. While we cannot know if this information was at all useful to the originator of this thread, I know I appreciate that information and will add it to notes.
These forks are truly interesting, and I have often wondered if they might have some subtle part in the origination of the Zhu l' Fiqar sword blades.
In the Persian shamshir versions, they are close parallel forks very much like these and on the military forks of Europe.
Thank you very much for answering Dmitry,
All the best,
