Unknown knife, Coachman knife?

[Sajen]

Hi Stelio,

have received the knife and was able to remove carefully the rust. Since the blade is very tiny is the inlay work outstanding. Soon as possible I will take pictures and show they here. I am correct that this will have been a dagger for someone with wealthy status?
I think the handle is original, it shows much use. And also when the seller was very good not to show the repaired handle by his pictures is it good visible but well repaired. The scabbard is pure thick metal without wooden inlay. Can you tell me more about this sort of daggers? And maybe examples?

Regards,
Detlef
