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
My wife bought a Hart brand shop vac and it nearly caught on fire the first time we used it. We swapped it for a DeWalt branded one (which are not actually made by DeWalt) and haven’t had any issues.
