That's what I was thinking, Rog Peek. And the hammer and vice technique sounds like it might be a bit of a nightmare. I doubt if I've got a vice that could do the trick.

I can envisage some kind of makeshift torsion device where I could twist a cable attached to the errant tine/prong and pull it back into alignment, but I can't see how it could be set up.

I'm hoping the ingenious Mudcat community can come up with a cunning plan for doing this, or solving the problem in some other way.
