Found these in a corn field in southeast Ohio. Can anyone tell me what they might be.

While walking a corn field last month I found these two items, took them home and cleaned the mud off. The pointed one is very smooth on one end. The piece that has the 3 points is smooth around the edges. Can anyone help me to identify them.

Welcome to TreasureNet! Can't help you with the rocks, but I hope they are stone tools.

Terry thank you very much.
I've followed Teasurenet for awhile and decided to join. Great sight with good people.

What are they, stone, iron, size reference? Same shape of a sickle mower knife blade.

The one with 3 points, each point is 3 1/2" from its center it's made of a stone material. The knife type item is I think red slate and is roughly 7" long. The knife type has a well formed front edge and similar to a knife.
