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
Yeah the E6430, as far as I understand it, was mainly a chipset upgrade to support Ivy Bridge processors, with some additional niceties like USB 3.0 and minor cosmetic differences.
I also had that sting from it too! Usually when it was on charge, I just always thought it was some kind of static electricity or otherwise some poor grounding.
