Normally, I’m not a big fan of makeshift EDC kits like this, but The Urban Prepper usually does a good job with this kind of stuff and this project is no different. To give you an idea of the unusual contents, he includes a mini Leatherman multi-tool, USB charging cable, and a mini ratchet tool as a few examples. He also includes commons items you would expect, such as a mini Bic lighter, money, a few medications, and plenty more.
Overall, it’s a well thought out kit and one that fits his needs specifically. As such, you should tailor the contents to fit YOUR needs if any of the items included aren’t particularly useful to you. FYI, if you want to view the PDF he references in the beginning with all of the kit contents listed, you’ll need to navigate directly to the video description and use the link he provides there.
