Not sure about this one, what do you think?

I found this about 20 years ago, I have showed it to a few people and everyone who holds it ends up holding it like in the pictues, fits your hand just right. Has anyone seen something like this before, I always just figured it was a scraper, or maybe just a rock? Thanks for your thoughts Mike

Just a natural flint cobble. IMHO.

I have to agree with Chuck on this.

Thats ok. I have bunches of rocks that look like they should be something
Keep hunting.
