I'd take that 1 step further and check with a library or college professor on those. Be very interesting to know the exact use of those.

Bloodcrick, (He is our resident rock expert) seems to think somebody has just roughed them to shape and stashed them. Then when he had more time he would go back and finish them. That's why some look pretty rough around the edges so to speak.

nice

Nice collection. Depending on the factors, a few of those could be worth thousands. You really should get them checked by a pro.
I cant really tell you too much, because I have no Idea of your location, tribe, and most importantly, size of those pieces. care to take a pic with a tape measure next to one for reference?

Here ya go shrewbeer, from Jersey County(West Central) IL. Near where the Illinois and Mississippi Rivers come together.

Very cool! I'm no expert, but they look like tools/knives that they skinnedcut up the animals (deer,buffalo,etc.) with. Great finds.

those are spear heads and hand tool type heads. Arrow heads are pretty small, they really wern't much bigger than the arrow diameter. I am no expert but saw that on a show. But reguardless they are cool.

haha is that a cat in the bottom right corner lol but yea those are awesome i havent found any in forever

i have a ton of these from tenn.
we go out in plwed fields.
the arrow heads will be alot smaller, and usually pretty short. spear heads are a bit onger but still narrow. those look like rough naps or knives to me.

awesome!! ive always wanted to get into that, just never have....

2 buddies were groundhog hunting and i pulled over to join them....when they sat down in the foot high alfalfa, the one buddy pulled up an absolutely beautiful arrowhead...guess theres supposed to be a good bit of that sorta thing in the area....ive never really looked...always looking at the ground but havent spotted any yet....

a friends friend hunts them hard....hes found tons of them.....guess its like shed hunting...gotta have an eye for it....he says he goes right after a rain and he says they shine a certain way that other rock wont..
