You are probably correct but as with most things around the farm they were most likely a multi-tool. Here’s a pic of some of Dad’s, I was never allowed to use the big one it was Dad’s.We always had a couple in the barn or on the baler. It was a lot harder pulling bales up off the baler without one, or pulling bales loose off the wagon.
One thing to note though, is how stout the point is. Bale hooks seemed to have a narrow point. They could poke into a bale easily, especially ones with crunchy stems. This one has a stout fat point. If the narrow point was stabbed into wood, it could break it off (been there). A stronger taper would stab into wood and let loose without breaking. Letting loose with a twist would be key when stabbing into wood.
I had to reread the thread and I thought I might comment on this. If it is not legal your excuse might work if you have your story straight and keep your comment short.I wonder if that's legal here in NJ for under my front seat? I'm in very rural area, maybe getting a bale for my horse?
