I think any of the slim lockblades with with the pocket clip are well-siuted for sock wear.
For all but the most formal events, I usually have a Jaguar M4 Balisong knife peeking out of my sock. I plan to get one of the Cold Steel's fiberglass skean dhu knives also.

I would never throw a knife unless I didn't care if I got it back.

I don't like to carry expensive knives, the lawmen here tend to confiscate them, or even worse, I lose them.
