I keep tools in my jar of pennies to keep my pennies from rusting. :)

What salt are you talking about? How can you have a current flowing? Am I
Is that a newly discovered element? Never heard of IIRC on the periodic
I just spray my tools with a very light coat of oil and Voila, no rust.
Yep ... it's called "electrolysis" ... and it'll remove the hair from your
If I recall correctly, it's on the underside of the periodic table, in the
corner between two aprons.
That works ... till the oil evaporates.
Never heard of it in a toolbox but it's not impossible under the right
conditions. Two dissimilar metals in a saline solution can result in a
current flow and eating away of one of the metals ... historically plays
hell with boat propellers.
Most newer outboards contain zinc sacrificial anodes attached to the lower
unit. Modern props are usually aluminum or stainless steel (and even some
plastic composite ones floating around out there). Not sure what all they
have for the saltwater environment, though....
I run watercooling in one of my computers. People cringe at the thought of
water mixing w/ electronics. However, distilled de-ionized water poses
little risk to electronics simply because it is a poor conductor in that
when working at GE Nuclear I cringed when I looked down into a huge
water-filled chamber brimming with electrical devices and lights! I
asked how can they do that, and as you've already guessed, it was filled
with DI water.
Dissimilar metals and their electrolytic action work faster with brine, but can
work with ANY impurities in water. Whether or not this has any bearing on
copper preventing rust on tools, I don't know...my guess is no, but I'm not
going to rule it out until a metals guy tells me to. But I'm not going to load
up my tool boxes with pennies, or even strip copper, either.

I had one of the few jobs that required water and electricity
together- a High-Voltage Test Technician. We would soak reels in water
for 6 hours and then "shoot" (charge) them. Looked like an arc welder
underwater when one blew.
