Third vote for the Kershaw Mini Cyclone. There's nothing "mini" about this knife. The Ti Handle fits perfectly in my slightly over-sized paws, and ZDP 189 is probably the best blade out there. For about $ 140 shipped, it can't be beat.
Plus, Kershaw's customer service is the best, and Thomas W., who is a regular on the Kershaw forum, will go out of his way to see his customers satisfied.
Also, I just bought a Scallion flipper, but it's a little smaller than you want, but it does fit in the watch pocket of my jeans, and like the Mini, is smooth as silk.
I also have a SOG TF1, black serrated, and the SAT was fun at first, but give me a good flipper any day of the week over the AO. There's no comparison.
