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’ve managed to get a hold of 3 of the old ones through garage or estate sales, but yeah the ones that are brand new have plastic parts in them which drives me crazy. But you can at least 3d print what you’re missing
