I'd bet that the best quality knife you can get in this category is still a Victorinox SAK. Your choice of pricepoint, and features as well. Lots of fun choosing which combo works for you.
Opinels are still the best slicers made, unless you can find and afford a working light saber.
You say you want a pocket clip and one-handed opening? You can now get the classic Mercator "Black Kat" with a pocket clip, your choice of carbon or stainless blades, and flat black without the logo (which I consider much classier). I attached a black thumb stud to mine and it works just fine.
