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
Welly tin.
They’re those cute tins filled with themed bandaids you can get at Walmart. Normally they’re brightly colored and targeted to small kids. Not only are they pretty good fabric bandaids but the tin is really reliable as a homemade med pack for camping. Small, light, brightly colored, and stupidly durable. Had mine in my bag for about 5 years now and it hadn’t even dented.
I use an Altoids tin for my first aid kid, for similar reasons. The damned things are basically indestructible as long as you’re not going out of your way to crush them. The one in my pocket right now is probably 5 or 6 years old. I prefer the smaller form factor, because I typically only pack for a few blisters or scrapes; Anything larger would be referred to the full first aid kit in my car.
I did the same for a while before the Stalker nerd in my lizard brain bought an AI-2 aid kit, gutted it, and converted it into a personal aid kit.
