I found this along an over grown Carriage road approx. 3 inches deep. It is thick heavy and weird. I am thinking it is some sort of plow tooth but not sure. Maybe a Harrow tooth? Any help appreciated.
UPDATE: Thanks to MiFarmer for this photo of a Horse Drawn Hay Mower. It shows the spikes that are under the blade of the mower. It is a perfect match for my Dagger Thingy!
