Yes, you do have my attention. The perforation does make it probable that your dagger is from Palestine. It is worth noting that in Ottoman times, modern borders between Syria, Lebanon and Jordan did not exist and there was a cultural continuum between areas.
Much is still unknown. For example, the three daggers in the last picture are thought by some to be North Palestinian or Lebanese, while others say they come from the Gaza area - I have seen one with Gaza written on the blade.
Anyway, you have a nice and quite uncommon type. I added few from my own collection with perforated blades that are of somewhat later date.
