EDC, just a Spyderco Jester on my keychain. In my belt pack (not always carried), a SAK Explorer. I was just on a plane trip and carefully put the SAK in my checked bag but forgot about the Jester and of course the TSA hassled me. I had a carry-on bag full of electronic gear and there was adequate time before the flight to go back to the counter, so I put the Jester into the bag and checked it. My cell phone was also in the bag, and somehow (probably during baggage handling before the flight) the phone got turned on. So it was on and broadcasting from the luggage compartment through the whole flight. Brilliant work, TSA.
