Good question Fearn
"Can you make up a story about the magnetized knife lying on top of a horseshoe magnet or two at some point (the legs of the horseshoe perpendicular to the blade). That would give the magnetic pattern you describe."
Good question, I measured the distance from each change of the compass needle and as best as I can tell it is this; start and then 4 1/2" it changes and then back again at 7 1/2" and back again at 12" so the "legs' of the horse shoe magnet if used were not of equal distance.
