Please help on an Islamic sword

[fernando]

Thank you all for your postings.
Robert, i remember now that the seller associated the scabbard end to a certain poisonous snake, but i don't think he had a strong basis. I well understand your relating this part to the elephant tusk ornaments.
Hi Jim, great info, as usual. I will search into Sabaki.
I confess my ignorance, as not being able to look at this specimen and distinguish which parts are of Indian ( Islamic ? ) influence, and which have an Arabian ( Hejazi ) shape, as i have no basics to judge it. A little help would be much wellcome.
Thank you Andrew, for your kind coments on he koftgary work. These inscriptions were the strongest factor which opened my pocket, to pay an absurd price for this piece. No, the Seller doesn't know its provenance. He bought in auction with an Arms lot. He remembers having concluded that these were kept well stored in the same place for three generations, and this dagger would be from the 3/4 19th century ... but all very abstract.
The more direct sign to its age use is the velvet section, with its comb worn off, and the one only worm hole through cloth and wood.
I am dying to know what kind of wording is these inscriptions.
Kind regards
