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
Casio G-Shock GWM-5610 – the current model number of the original 1981 G-Shock digital watch. Resistant to dust, shock, water, and up to 20 bar pressure. Self-charges via solar power. Self-synchronizes to GMT by passively receiving continent-spanning radio time signals. Little bastards cost less than a hundred dollars and are effectively bombproof.
