Thank you! Yes, the one on the right is roughly the size of my palm, and the more I handled it yesterday the more I thought there's no way this ever flew despite many pictures I found online of similar objects that were referred to as arrowheads. It does seem, like you said, either a skinning tool or digging tool. The other weird thing about it is it doesn't look like the other rocks I have around. I'm going to have to get a closer look, but it seems to have a lot of quartz bits embedded in it. Maybe the chipping process exposed them or this came from somewhere else. Thank you Amoonwolf for the advice. My daughter is a rock collector and she will be happy to know this rock had a use
