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
You can get butane and arc lighter inserts for zippo shells. I’ve had the arc lighter for going on 3 years, I’ve only had to charge it 5 times, it’s gone through the wash twice now and it’s still working great.
Bought my best friend the butane one the same time. She’s a heavy smoker, not only is it her conversion starter but apparently it’s been cheaper than buying bics.
