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
And for a buy-it-for-multiple-lifetimes citrus juicer to get juice for the blender, there’s the Nemco 55850.
