What type of blade is this?

[Cachefind09]

This blade is 5-13/16" long from base to tip and is relatively thin for its size and is believed to be from Ohio. It doesn't appear to be a Stanfield or Cobbs as it tapers at the base with the widest part at the middle? One blade edge is flaked very nicely and looks like it was the cutting edge.

Very nice blade unsure of the type though. It is big!

Not sure of type either, it's a nice one though.

A blade.

The material looks like Mill Creek Chert - to me from the photo.

In addition it looks like a spade, if you turn the photo upside down. It may not be symmetrical but this could be the result of use wear or damage and then knapped into this shape.

Maybe

It has the general outline of a Cowhouse Slough, but the serations and location would be unusual for that type.

My first impression is that one side didn’t get cleaned up and shaped as nice for some reason, so maybe it was intended to be more parallel than wide in the middle. But it is a big one.

OPs blade looks like an un-notched early stage Thebes. Size, shape, flaking point that way to me. Just a big skinning knife. Here is similar with notches.

Could be a cache bi-face ready to be finished into whatever the maker desired.
