I have been watching this thread with interest, just waiting for someone to
say that you bought the wrong sort of fork.
It sounds to me as if you bought a broad bladed fork, the sort that used to
be used for lifting potatoes, these have wider tines than the ordinary fork.
I have been looking for one of these locally, but no sign of one.
I just wonder why you didn't look at the tines(prongs) when you were buying
it.
