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
I recently bought a zojirushi rice cooker because of their reputation for making perfect rice and lasting decades. So it’s the AK of rice cookers. Or more like the AR because it was $200.
