Afridi Dagger ?

[Queequeg]

I just finished Death in the Silent Places by the late big-game hunter, Peter Hathaway Capstick. In Chapter 6, he wrote about Colonel Edward James Corbett, who killed an infamous leopard, dubbed "The Maneater of Rudrapayag". An excerpt on page 223 caught my eye:

The rifle was useless now, and Corbett knew it. With grim determination, he shifted it to his left hand and drew his knife, a wicked-looking Afridi stabbing dagger he had bought as a curiosity from a deputy commissioner in the north. With three notches in the handle, it had been the killing weapon in a triple murder, an old evidence tag attached to the hilt at the time of the purchase.

Does anyone have any idea what one of these looks like? I'm coming up short on google image searches.
