Yep! Hunting dagger. It is the widening of the blade relative to the hilt that prevents the hand fom sliping over the blade. Czerny's has a couple on sale in their upcoming auction (lots 324, 326, 328 / auction 71) so you can check their website also. Yet, many times I found mistakes on their website, so it definitely cannot be taken as reference.
But let us wait and see what others have to say.
PS: Had lentils today.
