Field Hunt, Hematite Disc?

[rock]

Well I went back to the field today cause the farmer said he might start planting soon. This is a no till field by the way. Everything is on top mostly. I did find a crazy thing I think it is Hematite and it looks like a disc, scrapers, cores and a Spokeshave. Not a bad day if you count all the brokes with them. Thanks, rock

I dont think it is a disc now maybe a Hammer stone. Cause of the strikes in the last pic I posted.
