I mean… I’d probably be down for whatever if someone gave me a perfectly made stone hand axe.
Though it could have been given as gifts, either for courting or for other social interactions. “I made this nice thing for you.” If it was for courting it could show that the person knows what they are doing, is skilled in creating stone tools and can provide for the family.
It could even been a form of money or trade, which would explain piles of unused ones.
