Hi AJ,

I think those flaked obsidian are "spear" heads, not arrowheads. They were the sharp end of a weapon known as a mata'a. On a short shaft, they were used as a short spear/dagger/axe, while on a longer shaft, they became polearm heads. These weapons were used by the toa (warriors) and matatoa (master warriors) who basically took over when Rapan society broke down. They're quite common on the island, (un)fortunately, and they seem to be quite variable in size and shape.

Best,

F
