Pinch bar or digging bar, but I've not seen one with a bulbous pointy end before though, maybe it was blacksmith rather than machine made. The mushroomed end on the other end comes from many whacks with a mallet, it'd have started off straight.
If I was your neighbour I'd rather have that one back than a new one, possibly with contact details of a blacksmith who has agreed to fix it, as it looks like it's seen some action!
