Would readers be willing to describe this dagger to me?

I'm reading a series set in mid-18th century England, and one of my favorite characters carries a small dagger with a curved blade, and it sounded so charmingly baroque that I wrote the author and asked what kind of knife it was. She replied that it is a Turkish ceremonial dagger, and there is a picture of it on her Pinterest page

Would anyone be willing to describe it for me?

Thank you in advance!
