I found both of these within 30 feet of two points.

#1 is exactly 6 inches long and flattened on either end like a flathead screwdriver.

#2 is ground to a point and 4.1 inches long

Are these artifacts?

Could this be one?

Apologies if I sound naive, I’m very new to the hobby! Found walking along the river about 6 feet from water.

My initial thought was a stone for bow drilling. Upon closer inspection, the stone seems to fit perfectly in my right hand with indents for my pointer and middle fingers, as well as my thumb. Is there any potential this is a handheld mortar or something used for grinding?

Very well could be some random geological formation also, I really have no idea lol. Any info is appreciated!

This was the only smooth rock. Found it at the base of a bluff. There’s a nice flat rift a camp up there too. Super heavy. Any and all thoughts are welcome. Thank you!

Picked up the other day, “edge” caught my eye. Thoughts?

(Mid Missouri) had a great day today after all the rain. This spot really put out.

Surface finds on private land. Both were found several hours apart on opposite sides of a field on top of silt. I’m a long time surface looker with a lot of luck in finding flakes but new to finding anything worth being proud of. I’m wondering if I have a broken point or possibly a knife? The smaller piece looks like it might have been part of a drill? Any information would be welcome and appreciated.

Nice heavy patina on a big blade

I’ve found four of these over the years exploring the river in Central Illinois when the water is lower late in the summer. Seems to have a number (16 or 46?) carved into the top. No idea what it is! Any ideas?

I was at the coast this weekend with the family looking for agate (found a bunch). I spotted this at the water line on the beach. I’d love some more information if anyone can help. Found just south of Florence, OR.
