Can someone ID this? (arrowhead)

[Lasercats]

This piece was found in Upstate NY. Ithaca to be precise.
Not sure if you would call this an arrowhead or what...
The edges are worked (hopefully you can tell from the pictures), and I'm not sure if the "back" side was smoothed or polished or just naturally smooth.
Not sure on the rock type, I was told maybe Basalt or Ryholite, I'm not really sure.
It's also about 4 1/2 inches long.

If anyone knows what kind of tool this is, what type of rock, etc, I would love to know!

Looks like common shale to me

No way that was an arrowhead unless from a Roman Ballista . . . and they'd have used metal.

I believe what you have is a spall broken off a larger rock. Probably by natural events with no human intervention.

Could it have been used as is for a hide scraper? Perhaps.

Sorry I have to disagree Icewing, wouldn't it be brittle if if was shale?

Hey Charlie, thanks for the info. I put arrowhead in the title so that people experienced in American Indian artifacts would check it out. I see the resemblance to a scraper. I really don't think it is natural due to the flaking (which may not be easily visible in the pictures I posted) and the shape.

Yeah that light blaring in the background doesn't help things....take a few pics outside today...

Sorry, no signs of it being worked by man at all.

I can see why you have the notion this may be an unnatural artifact, as it is a piece of stone struck and broken in the very same way one would break free a thin blade from a core stone. I would wonder myself if it was broke free by man or was it done in a natural way by one rock hitting an other? IMO your find is kind of like how the cookie crumbles. This one you just can never know for sure how this piece of rock really came to be If the edges were further worked, it would be no doubt as to how it was created.
