I treat my one Calphalon hard anodized like cast iron. The chain mail scrubber
doesn't seem to scratch it at all. In a few years, that pan will end up at Goodwill,
and I'm sure it will hold up fine until then. I agree that it's fun using it. I originally
bought it to clean my wok. There are no sharp surfaces, so it doesn't seem to
damage the HA surfaces, and yeah, it "feels neat using it."
