really?
i thought wyoming?
here is yours along w/your dad's
i think your dad's blade is made from petrified wood, not??
they might be points but i'm thinking more and more that they were blades for a 3,4, or 5 bladed rib bone knife handle
imagine those two blades along with one or two more being hafted into a rib bone handle
they could have made quick work on cutting buffalo or elk meat, or any animal being processed for food, clothing, tools, game pieces, etc.
way way cool man
you guys did good
