What is that?

[SRCooper]

Not knowing how big it is, I amnot sure. Many stone artifacts were for shaping wood - and that might be what the groove on this piece is for?

Being quite possibly BC...more than likely a tool for shaping wood.Wonder though if could be for building or a building piece itself...

Could possibly be a shaft straightener?

Some shaft straightener or abraiding stone?

I have found two in my life, made in glacier slate and its a broken shuttle bannerstone. Yours is made of granite and looks to me as if had been in water which causes the black on the surface. All of my finds were in ky.  Yours is one of a kind yours in the granite and not slate better material. Great piece!

It really depends on size..Too me? looks to be a foot long.If its only inches?...Could make difference on identification...although it could be a large shaft straightener..could be a small one...Interesting.

I have found one almost the same. Here in Washington we would call that a shaft straitner. Like others have already said. The stone may have had a second one that was the other grove and the wood shaft held in the center and ran in and out would round it off the size they wanted. Mine were about four inches long and most likely for arrowshafts.

Hey Chi Yuan...we are ready for the size..Tell us the size...It kinda also looks river stained or water stained..I would think a shaft straightner would be smooth in the groove,but time might have roughed it up a bit..If it is large?..maybe it brought water to the temple? ..waterfall?...

Thankyou Chi Yuan....This is most for sure a shaft straightner..Quite possibly a bannerstone....Yea!
