A good resource for Samoan material things can be found [

[
Here] is their article on
nifo'oti type clubs.
It would seem as if the wooden
nifo'oti had less practical combat value than the metal bush-knives that were all the called the same... If I am not mistaken, Samoan fire-dancers still use blunt bladed flaming
nifo'oti for their fire-dances. The bush knives can still be found in Fiji I think, but I have never been to Fiji and I am no expert.
