Ahh.. something i can actually give feedback about.
Try the Starmate from spyderco, it's coming out soon. I'd avoid anything from REKAT though, the carnivour is the most benign looking but still rather "threatening."
Microtech mini Socoms are nice. 3 and an eigth blade lenght. 154-cm blade steel. And they come in colors.
Also at bladeforums, (not sure if its a possibility) but theirs a forum commemrative knife that's bright blue and not threatening at all.
