For a long time, I have carried a Smith and Wesson Baby Swat with the skeletonized handle and blackened blade. Don't laugh, it has been a great EDC knife for about 7 years and has been very durable. Lately, I have been itching for a new knife. I recently bought a Kershaw Skyline, which is a great knife for EDC tasks. But, I have found a place to get knives pretty cheap and the Spyderco Tenacious/Persistence anf Sog Flash I have been on my list for quite some time. I want to know what you would choose for your choice of EDC blade. I myself have been leaning towards the Tenacious because of the slightly larger size which could double as a tactical folder if need be. I'm not saying the Sog can't be used in an emergency defensive situation, but the small blade is going to restrict it in this role. But, the Sog is so light that it would be a dream to carry.
