Interesting - I first saw a steely about 10 years ago,when a mate decided
they make good washers with a hole drilled through the middle (at less
money that proper washers of the same diameter).

I first noticed when I was explaining magnetic and non magnetic metals
to my son "here, look, this 2p's made of copper and isn't magnetic. . .
.. eh? What the?"
