The problem is specifically with the smaller pot (4c maybe) but that's the one I use by far the most. I assume the corrosion will eventually happen to all the rest. I ended up with 2 sets of cuisinart cookware and it's almost back down to one set. For all the money those cost I could have gotten a couple of these indestructible things that'll outlive me. There's probably something like this but more cost effective I'm sure.

I have more cookware than I can use already though. Too many knives too. I do love my Mercer Renaissance, it's a $40 clone of the Wusthof Ikon Classic.

"What if I need to heat/cook some non-food stuff?"

Like making candles, soap, or fire starter logs.

I care less about a skillet lasting a lifetime than I do about the ease and efficiency of the cooking experience. (Those toxic non-sticks should be thrown out when they start showing signs of wear.) But I'm also pretty happy to get that without having to use the toxic coatings.

I can't remember if I mentioned it, but I keep a tfal non stick pan for eggs. It's important but I just expect to replace that every few years as necessary so, I wouldn't spend a lot on nonstick. Something like this would be the only reason to spend a lot.
