Indo / Arab Jambiya

[Miguel]

Hello Everyone I would like to share this item with you and to solicit your assistance in determining it`s origin.

I think it is a beautiful design of weapon in it`s simplicity and symmetry. The hilt of an Indian pistol grip design in polished Sardonyx stone whereas the blade and scabbard are pure Arab from south Yemen called `Hejaz`. I have never seen an Arab Jambiya with a stone pistol grip hilt so I am inclined to think that it is of Indian origin but I just don't know. There seems to be some punched decoration or inscription in the centre panel of the scabbard if the latter I would be grateful if someone could translate it.
The overall length is 12 ins with a blade length of 7.75 ins x 1.75 ins wide.
Thanking you in anticipation.
Regards
Miguel
