I just receveided my new toy !
The hilt must be ivory ( elefant as Ariel said ) and a repaires piece made of resin...
The scabbard seems made for the blade, 
not shortened...
The mounts fits good too .
The foliage work suggests me mongolian ( saw look like embossed silver work with stylised clous...) 
or Himalayan origin as we said.
( coincidence ,the karud come home with snow falls today 

   )
I forgot to mention it: dagger length 46cm,
52-53 cm with scabbard
