I bought a 9-inch cast iron frying pan at a second hand store more than 30 years ago, and who knows when it was actually made, and except for the fact that it’s so thoroughly seasoned that nothing ever sticks*, it shows no sign of wear.
Cast iron fry pans are handy for a lot of things. My ex clobbered her 2nd husband in the temple with one when he tried to strangle her. When he came to he’d forgotten everything. At least she had the sense to GTF out soon after that.
* This may be because it’s machined on the inside bottom, something you don’t see any more on new ones, even fancy ones.
