Help identifying these finds

[wymanwvp1]

Found these in Westmoreland County, PA near a creek...

The one on the top seems to be somekind of axe or tool to hollow out canoes or something... You can't really see the grove real good but there is one on there and it was like sanded on both sides and both ends come to a point....

Anyone have any ideas of what these are?
Thanks for the help!

Well, after viewing your finds, I hate to piss on your parade but these appear to be just plain rocks to me.

Top one looks like a fleshing tool. Used to skin pelts from the animal carcass. Not to sure about the others. D.D.

Hey thanks for the responses! I forgot to put something in for scale so here are the dimensions:
The one at the top is L9"xW3"xD2 1/2 at the middle then tapers on both ends to a point. The bevel is 1". The groove is also 1" wide.
The one on the bottom left is L3"xW3 1/2"xD1". the 4 grooves are
L1"x W1/8x D1/16.The other side is domed.
The one at the bottom right is L6" W3 1/2"at the middle xD1"
I don't know if they are artifacts but the top one and bottom left both seem to be designed.
Any help would be greatly appreciated!!! This is a cool site!!!!---wymanwvp1
