Bali ceremonial knife

[VVV]

I have noticed that the old ones usually don't have the swastika pattern, so maybe it's the other way around?
Here are two blurry cell phone pictures I shot when visiting the Klungkung palace museum. There seems to be a difference between the ceremonial axe and this "household knife", both in use and name.

PS I have one and used to have an additional that I traded. One is plain and the other have an ornamented blade. Both of them have this kind of scabbard, old style makara hilt, the "monster" protrusion and inlay on the back of the blade.
I suspect that the makara hilt, more than if there is inlay on the blade, is an age indicator.
