On second look and thought, I am now considering Ed did NOT use something between the plates. The lighter lines we see may be just years worth of dust finding its way into the rusty grooves. It might have been stranger to not have these visible lines, perhaps. His plates seem to be (duh) less than medical precision manufactured.
What about "rusted together" for a magnetic lock? Is it unthinkable Ed created the lock interface in an especially salty liquid or other oxidation circumstance? One thing rust offers: a softer surface to grind on, possible with a mating rusted surface. As far as I know, rusted nails can jump on a magnet just fine?
