According to Wikipedia, Every Day Carry (EDC), “refers to a small collection of tools, equipment and supplies that are carried on a daily basis to assist in tackling situations ranging from the mundane to the disastrous.”
While there can be something of a suvivalist overtone to EDC writings, I just see them as neat ideas for CNC projects and something a machinist ought to be carrying around in their pockets. They’re typically little tools designed to go on your keychain or on a chain around your neck. Here are a few to take a gander at so you get the idea:

Tapco Armorer’s Tool

Atwood Poltergeist
I’ve got links on a couple of those in case you’d rather just buy one. Aren’t they neat? If you’ve been pondering a project to make a knife, perhaps one of these EDC implements would make a simpler starting point to play around with. Check out CNCCookbook’s Pinterest “Guy Gear” Board for a lot more ideas. With a CNC, your imagination is really your only limit on what you can build.
