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
Other people are saying “cast iron” or other broad brands/categories, but this is the only one that doesn’t fall under OP’s request?? Nonsense.
