The KaBar Dozier series is smaller than the Mules, but they are great EDC folders that won't scare most people and will work very well. KaBar does a fine job with AUS8 steel. It gets extremely sharp pretty quickly. The F&F on the Dozier KaBars that I've handled has been excellent for a knife at that <$50 price point.
