What is this? A Cultivator tooth, the tip of a Lance, top of a fence railing? It looks to be rough forged, there is heavy pitting on one side of the shaft. The shaft is broken off from whatever it belonged to. I picked it up at an antique store in Bridger Montana along with some old files. It was at the bottom of a box full of old tools. It looks to have been caked in dirt at one point in its life. Any ideas?
