No one etched the actual password into anything for them, they bought a product[1] that includes a bunch of steel disks or tiles with letters engraved on them. You then assemble the pieces - either by sliding the tiles into the grooves of a card-like thing, or by putting the disks onto a spindle that you put into a tube (depending on the version you get). It seems cool, but the site spends a lot of time talking about how difficult to destroy they are, which makes me wonder how much of a PITA it would be to destroy the left over tiles/disks (so no one going through your trash could figure out which letters you used).
