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
Also, this is an old meme, and a bit outdated for our times, but no one has mentioned it so ill do it. The Nokia 3310. Truly the AK-47 of phones.
