Bought a couple different CRKT's off of Ebay. The "Stiff KISS" and the "Dogfish".

Both very simple, skeleton type with a Kydex sheath. The "Dogfish" has a bottle opener on the end, the "KISS" is longer and straighter. I dipped the handles in that rubbery-plastic stuff to give them some grip.

Haven't carried either around my neck yet but I've tried them both out and will carry one of them when needed/appropriate.

Very reasonably priced, the "KISS" was a little harder to find as it's been discontinued by CRKT for a couple of years now.
