I keep thinking about how easily magnets mess things up these days -- computers, mostly, but also credit card mag strips. Gotta be really careful to keep your powerful magnets away from stuff that can suffer damage from them.
That brings me to the question, is the magnet in the T-mag likely to cause problems being in a pocket that can come near electronic devices, or wallets containing credit cards, etc.? Just how powerful is the magnet, and how far outside the knife does the potency of its field extend?
I have those tiny Geomag toy magnets, and I brought one near a computer monitor. Had to degauss the thing several times over an hour to get it back to normal! And I notice a flux in the screen (a CRT) when one tiny Geomag is still about three inches from the side of it!
