My two toolboxes are were I store my magnets, there is an assortment of them all over the front, they've been there for years as well.
Pete, I wish I could find a dehumidifier that would last five years!
Stan, I've also bought a bunch of magnets from K&J, they're my go-to source if I need a magnet. Interesting fact about how hard the material is, I've never tried to cut it, and I can see it would be "interesting". That part about catching fire makes me think of magnesium.
