Not good at this

[Diggie]

Any help identifying this is appreciated. It is worked on all edges. Any suggestions on a good resource for tool identification? Thank you
Found in St. Louis County, MO

Nice tool I would think . Looks to be resharpened with the scalloping on the sides . Nice Radom flaking and it looks like a costial plain Chert to me .
See what the experts say .

[Hoss]

looks like a chipped adze . Nice find diggie thanks for sharing

[Diggie]

Thank you Tam & Hoss for your help.

I do not think it is Coastal plane chert. It is not found in MO. It is likely to be Burlington chert which is white to light tan and found in MO and Ill.

I agree with Hoss on the adze ID.
