I second the Benchmade Benchmite (more enthusiastically than Stretch).
Same here. I've got a ton of these Benchmites (blue class, black class, and red class versions), and I love them. For a small pocket folder their excellent. No clip, but that can be easily fixed with a clip from a pocket watch, like I did to the blue 310 in this picture:
I bought a few for my father (who has a problem finding knives he likes, since he doesn't like anything real thick in his pockets) and he loves them too. First good locking knife I've found him that he really likes carrying.
