What is the best victorinox lock- blade?

I need a victorinox lock-blade that is one-handed opening, and is thin enough to to be able to hold for a long time. I have looked at the "sentinel" but I need more functions, and I love the new "soldiers knife," but I don't want a serrated blade, because you can't sharpen them. I also liked the trekker, but I think that it's also serrated.
