Debatable though I'd you get solid cast iron like lodge or other quality non enameled, unless dropped on the floor (and even then) that might actually be BIFL. Heck, even if it rusts, you can sand it down, treat it 2-3 times in the oven and boom, good as new.

I love le Creuset, but if someone is visiting and happens to use it and scrape it with a metal something. That's ruined. Can't get it back unless you want to pay a bunch of money to get it re enamled and even then, it will likely be a poor enamle job and have weak spots that will get ruined again.

That or, like me, chuck out all metal anythings other than utensils, have mostly wooden spatulas, and that solves you running into that possible mistake, OR be that person yelling at people to "step away from my kitchen!!!"
