I have a question for you fine folks who frequent this forum. There is a lot of knowledge here, and I am wondering if someone might be able to help me identify these spear heads that I acquired about 20 years ago. The women who sold them to me at a garage sale didn't know where they came from. One of her family members liked to travel and one day, he showed up with these. I guess she inherited them and didn't like them, and thus they passed on to me (or so her story goes as far as I can recall). I have tried a net search on several occasion, but come up with nothing. Could be I am just looking in the wrong places.
What I would like to know is, what are they and what part of the world do they come from?
Fishing spears? War spears? Ceremonial spears? Some crazed art project gone wrong? Tourist trap paraphernalia? I have no clue.
I didn't pay much for them...I think 5 dollars for the pair. It was my thought to get spear shafts made for them and hang them up on a wall, but I would rather be more authentic (that is if they are real region specific spear heads) in shaft length and wood material if possible.
Any help on this pair would be much appreciated.

Showing the main spear point and two smaller side points.

Both spears are not identical. They have some small variation in pattern.

Huntsman for size.
