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
Gotta be the KitchenAid mixers no? Especially the older ones. I have a friend that has one from his grandma that’s over 50 years old. If anything breaks, it’s usually a gear or something simple to fix, and the parts are easy to buy and generally cheap.
The mixers are not exactly cheap though… and their other stuff is now mostly made from plastic (like the food processors for example)
