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.
