I think some of the posters missed the word "small" in your post.
All the Spydeco's suggested are outstanding knives but some of them certainly wouldn't fall into the small category.
Take a look at the Spyderco Dragonfly, it's big enough to be useful but small enough (and light enough) that you barely notice it when clipped to your pocket. (OAL 5 1/2", AUS-8 2 5/16")
