Electric Demagnitizers

[000Robert]

Striking a magnetized object sharply will jostle the electrons around (simplest way to say it). This will dissarange them from the order they were in when magnetized. It will lose most of the magnetism, but not all. It also takes a good hard blow. I wouldn't recommend it for a knife blade. It works fine for tools like screwdrivers and wrenches.

Maybe so, but I try to take good care of my tools, and especially knives. I would rather pay $75 for a good USA made demagnetizer than smacking my tools against steel. But that's just me.

By way of update... I picked up a South Bend for like $50 and it works perfect with no residual magnetism

That one looks just like mine. Mine works great also.
