Sorry guys
I don' like to be pessimistic but
the sheat / scabbard is Indian and not very old;
the hilt with the silver at the back is classic from South Arabian jambiya or khanjar;
in an Indian context, I'll say that it's a Jewish hilt from India or Yemen;
the blade is recent fake or printed wootz (if you scratch it'll disapear).
To me it's a recent fake Indian jambiya...made of different marts
the hilt is good & old, the blade is recent
Sorry
