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’m just interested in super high mileage capable vehicles. For instance my cousin has a 12v Cummins diesel and it has over 1m miles. 750k ish when he got it 10 years ago.
