Tumbuk lada with Malayan rhino horn handle?

[Sajen]

Here some daggers from my own collection, posted before in the above given thread.
The one in up I would call tumbok lade, handle big (pepper crusher), spine nearly straight, blood groove big and long, round section before hilt very big and round, blade nearly straight.
Second from up a typical sewar, curved slim blade, short tiny blood groove, section before hilt isn't round.
But what are the others? You cant classify ethnograhic blades like coins or stamps, look inside a book and say it's this or this.

You may have noticed that I go mainly by the blades, it's the heart/body of a knife/dagger/sword and with the overall appearance.
You have seen in the given thread that there are different views, all try to classify these lovely daggers but all do it different, who will say that it is wrong or correct?
