If fast deployment is a priority, I would Highly recommend the spiderko endura wave.
I have mostly Benchmades in my collection, but the endura wave opens "with a little practice" as fast as any knife. Its not as beautiful as my benchmades, but find my self carrying it because its engendered to open as well or better than any other knife that I have owned or handled. I cant quote its dimensions but it is more narrow than most of my knives of its length. If speed of deployment is not your primary concern, My favorite tactical EDC is my benchmade 950 Rift "plain edge". If your an admixture sharpener, Buy, and use a Spyderko tri angular sharping kit.
Hope that helps.
