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
Pinecil soldering iron. Cheap (only $26!), open source, portable, usbc powered. Even more powerful than $100 ones. I love that thing
