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 was mistaken. Vibratex, which made the original Hitachi Magic Wand, is still making them today. They just dropped the “Hitachi” from the name.
