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
Sony MDR-V6. I’ve had them for 15+ years, only had to change ear pads to velour ones after the first 5 years of use, after that 10+ years, no issues.
