Whenever I am able to salvage a hay fork, I turn it into a shepherd's crook. So far, I have not profited personally, although I hope Workaid has, but it's been fun!
I like this one best.
This double pronged hook I term a Devon shepherd's crook, for no better reason than I saw a picture of a Devon shepherd with one. Does anyone know the correct name? This would be good for drenching sheep, to push them under.
Here are some more.
