kphunter: How about the Buck Adrenaline BU-178BK; 3" blade, liner lock, ATS-34, Ti liners, and pocketable. I've tried the Adrenaline in a local store and it's a pretty nice knife. It might be my next Buck purchase.
Or maybe the Mini Taclite BU-886BK, discontinued but probably still available.
I recently bought the bigger Taclite 885, the store also had the 886BK, both very nice knives.
