Mandau with twist core

[VVV]

Here is my twist core kampilan. I haven't seen that many???
The reason why I don't think it's just a reshaped kampilan blade is that it's much thinner than a mandau blade.

And here is a parang pedang with twist core. That's the only one I have seen.
So if it's reshaped it most probably have been made out of a sulu kris.
