After the war, European farmers had to use what was available to work with. I have seen many bayonets used as tools for farming. They are always coming out of the "woodwork" so to speak. Mostly sharpened to heck and well used. Some modified to perform some task. This is the first one I have seen that was modified like yours. Not worth anything collector wise but, still a part of the S84/98 III history. Wipe it down with oil, put it up on a wall and let it be what it is now.Bought from Germany.
