OK ALL
I said I was winding down on my part of this thread started by
JENS, and after reading
Ann and
RIVKIN input on this magnetic stuff I should have stopped last week!

Do all you follow their exchange? Man that is some heavy stuff. Anyway I said I would do as
FEARN suggested and acquire a magnetic knife holder and zap a carbon blade.
I used a Case butcher knife, as was in contact with the magnetic holder for approximately five minutes, the pictures show that the blade did take magnetic profile with three pols.
I also took a picture of the Mysore dagger with four compasses on the blade to show you that it has the four changes all at the same time.
