Persian? dagger with rhino hilt

[Hommine]

[FONT=Times New Roman]I have a dagger with a rhino hilt and a curved knife. The hilt is in the shape of a Lion's head (?) inlaid with ivory. The dagger has a steel guard embossed with silver inlay flower design. Does anyone know where this dagger comes form and how old it is. there is a hole from each nose to each ear (to put cord though?). There are also 2 hholes in the steel know (next to the silver inlay work) any idea what that is for? The rhino horn has a beautiful golden shine, not visible on the photo's, in view of the aptina I assume it is very old. Who can help me?

Regards,

Hielke
