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 put the electric insert in one of mine, charged it in 2021… still works!
Now the electrics are good. I’m a believer there. Just not the old school kind as much when lighters are so abundant. Only issue with electric is the flame is often needed for other non smoking purposes and electrics have no flame.
