My grandma used to walk our farm fields all of the time, after we would dofall or spring tillage and look for both spearhead and arrowheads. She has quite a collection, I need to ask her to sit down with me sometime and look at them again.

I remember they were pretty neat to look atthe first time I saw them when I was a bit younger.

Appears that you have both spearheads and arrowheads.

Congrats!
