It looks like some dags have notches just behind the blade while others don't. With that, can one then assign the blades with the notches to be meant more for the native populations/trading whereas those lacking the notches were meant more for the "westerners"?
I'm not sure who made the kydex sheath, a friend of mine borrowed the knife and had it made by someone he knew circa 1999/2000. Kind of think it was blade tech. Although heavier I prefered the leather verison.
