Balato for comment

[Athanase]

Hello

Here is my first Balato, (South Nias I think from the style of the handle).
The back of the blade measures 7mm thick at its base.
The sheath is held by strips of brass with a plating of silver-colored metal.
I have looked on the forum and on internet and I think this balato is after headhunting period.

The patina of wood seems really old but I can't estimate his age : before or post WWII ??
