Hello
I finally found it. First for all things ethnic, let me recommend to you, if you only have one book on the subject "George Cameron Stones, A Glossary of the construction, decoration & use of Arms & Armour in all countries and all time" It tries very hard to achieve that, which is impossible but does very well in general.
This knife isn't usually known as a kard as far as I'm aware. Its a much closer relative to the Khyber knife (which is often more of a sword) from Afghan areas, known as a choora. There is a similar Persian version known as a Peshkabz but I'd say this was Afghan, Northern Indian.
They come in all shapes, sizes and qualities. They can be of considerable age or none as it is a very traditional style and continues to be made today.
Here photos of a couple of mine, similar but also very different.
