What dagger do I have here?

Hi!
I'll add that your flyssa is probably much older, around 1880-1890.
A good thing is your scabbard decorated only on the exposed part.
The late flyssa are often decorated on both sides.
We have an expert called Emmanuel, you can have a look at his threads...
And yes, in a way, it's Ottoman as Algeria was a part of the Empire...
Best,
