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 won’t regret it. Safety razors, and if you decide to, straight razors are far superior. I used a safety razor for a few years and then decided to get a Dovo straight razor and I love it.
