I have around 25 knives of all shapes and sizes but for an EDC knife its pretty hard to beat a Kershaw to me. An OSO Sweet or a Brawler fits your descripition though they might be a hair big, they are pretty slim and easy to carry and I like assisted opening. Best of all they are cheap at around 25 bucks. I have had about every kind of knife including Spydercos and admit that they and especially Benchmade, might have a tiny bit better steel but they will still need to be sharpened occasionally just like any other knife.
