Here must be one of the Indian Classics... The Tiger Tooth... In my view one of the most efficient dagger blades ever made. Often with a reinforced tip for piercing armour/thick clothing and with chiselled blade making for a lighter stronger blade. I assume the tang goes right through to the typical 3 lobed pommel  and there is one I saw with a tiger striped horn hilt ~ at 2 below..
