Grey flake knife

[sooner]

I found this little flake knife a few wks back in n. e. okla.My question is about the material. Its grey with little brown specs it also has a little sparkle to it which the camera did not pick up. It has a grainy feel to it not slick and glassy like a lot of flint. Ive got several points and a lot of flakes but nothing made of this material. Does anybody recognize it? thanks sooner!

Your trying too hard for close ups. Notice in the last picture how in focus you finger looks. You camera can do it becaus ewe see the finger pretty good.  Back your item away from the lens a bit and try some more pictures of the rock. Not sure anyone here can help ID that lithic but better pictures would sure help us try.
