I have no idea if this brain storm I had this morning would even stand up to one shot from a traditional bow. I took the base of one of my shed antlers and cut a section lengthwise that was close to a quarter of an inch. Cut that into the shape of an arrowhead and started filing down the edges giving them a similar look of a store bought double edged steel tip. Decided to give it a serrated edge which took some careful work with a very small file. Buffed it with my Dremel 400 XPR tool along with some extra fine buffing compound. Ran the edge on fine whet stone that I sharpen my knives and steel broad heads on to give it a sharper edge. It measures 1 1/2 inches in length and 15/16th inch wide at the base and is 3/16th inches thick. Doubt I ever let it fly at a deer but it was fun to make just the same.
