This is not a conversation about guns. This is a conversation about items that have withstood abuse that are near unbreakable.
Some items I have heard referenced as AK47 of:
Gerber MP600: It’s a multi tool
Old Thinkpad Laptops
Mag lights
Toyota Hilux
I think there’s only 2 ways to actually kill a cast iron pan. Dropping from a height that causes the brittle metal to break, or putting lead in it. Obviously no one puts lead in their cooking vessels, but small pots are/were used to melt lead to pour in bullet molds, so if you find an old used pot, it’s good to check for lead.
Also, ceramic linings can get chipped.
You can mistreat bare cast iron horribly, never seasoning it, washing it in the dishwasher, or whatever, and it won’t get irredeemably damaged.
