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 been using the Casio W800 series (W800-H currently) for the past 12+ years. This is my 3rd watch, only because I simply lost the first two. However, it’s about the 6th strap, so it’s like the AK’s strap.
