Odd tool?

[Rockiologist]

I found this today in the same place I have showed stuff the past couple days from. It has had all sides worked on the top side more than others. What looks to be the tip has tool marks to the point it has almost rounded it off. Any ideas what it would have been used for. This was my last trip to this sight so I put the other pieces on here also. Still would like someone to take a stab at the second one never got anyone to give me an idea on it.
