OK, miss, since you ID the rock as a hoe blade, and since I am right next door in New England, I'll run a stem hoe by you from the Northeast:
A crude tool compared to the notched flint hoes from our southern states. To say the least. This example is made of a finer grain sandstone and was probably partly worked into this shape. Here is the description of this artifact class from the Massachusetts Archaeology Society's "A Handbook of Indian Artifacts from Southern New England"(revised edition 1991)by Curtiss Hoffman. Here, Dr. Hoffman quotes the original text by William Fowler, p. 69:
Stem Hoe: Middle-Late Woodland. "While limited in number, enough specimens of this tool have been found to warrant placing it in a separate category by itself. It's chief characteristic is a crook in the stone at the stem end, which was attached to the handle. The bit at the opposite end is thinned by chipping, and may be out-flaring or shaped more like a spoon, when made from a pebble spall....Scarcity of the Stem Hoe is due, no doubt, to the infrequent appearance of stone blanks with the required crook at one end."
Hard to visualize how they "worked" it since it is sandstone and while sandstone is good for bowls, pipes, and a lot of other things, they are artifacts that are ground, not flaked. Here's a close up of the bit on both sides. You also get a sense in hand that the right flank of the artifact was altered a bit, crimped or even flaked, but it's not the obvious nature of flaked artifacts of flint, etc. Horticulturall tools here include stem hoes, triangular hoes(even more difficult to recognize) and pestles. Metamorphic rocks were often selected, as well as sandstone. With the exception of pestles, almost all of these tools were very casual in nature, very easy to overlook because of the material and minimal alteration of the stone at times.
The fact is I bet many collectors walk by this tool. The native picked a natural rock with enough of a natural crook to use it as described above, once they trimmed the business end. And, in the case of your rock, perhaps that was the intention. However, your rock, unlike the one seen here, is not partly worked into shape, and your photo is plenty good enough to demonstrate that to eyes apparently far more experienced then yours. I don't doubt you have found actual Native American artifacts where you found that rock, and maybe it was a pick up and use kinda thing. But it shows no alteration by the hands of man, and it is not my fault or anyone else's fault on TNet that that is the case. You are just being unreasonable and behaving as if you are the foremost expert in artifacts who has ever lived and breathed. But, obviously you are not. Just relax and try to learn something. Since when did you decide you have nothing else to learn and that nobody knows better then you do? C'mon now, act like an adult for heaven's sake.
trying to follow the directions so other people can see the artifacts. hoe blade and etc. Just not technically handy. sorry.
Which doesn't mean it couldn't have been used as an expedient digging tool; it just was not worked into the shape you see, the shape itself is natural, and some stem hoes in New England can be very similar if there is a natural "crook" in the "handle" end.
