Get a Delica or Dragonfly. The Dragonfly may be a little smaller than you are looking for, but that blade handles tasks that you otherwise may use a larger knife for. The dragonfly is truly a little big knife.

I see your options and have given my opinion, but the best thing to do is go to a store that carries most of these knives. This will give you a feel for each blade.

One more thing about the dragonfly, my experiences have shown me that this knife is sheeple friendly.
