Spyderco Calypso Jr. If you can find one.
I believe the OP is talking about blade geometry. Not sharpness and not edge retention. How well a knife cuts. Of course there are different types of cuts.
A zero ground Spyderco Nilakka making a shallow cut into a soft material is going to cut with very little force.
An Opinel is probably thicker right above the edge but the Nilakka is thicker higher up because of the thick stock compared to the thin Opinel. So maybe an Opinel slices through stiff cardboard or an apple with less force.
My third selection was a Benchmade Mini Grip with hollow ground blade. This is a great slicer and a more versatile knife than the others. It's a great EDC.
I'd also give an honorable mention to the Spyderco Bradley.
Opinel.
Hard to believe the PM2 gets so much credit for slicing performance. That knife has the worst blade geometry of all my folding knives, mostly because the edge is just too thick.
From my modern folders, the Benchmade 746 has the best geometry.
What makes the stainless Opinel better than the carbon? I've only got the latter, just curious
