I can't find my name in the thread. I do not remember whether I posted here or in another thread on the same topic. So, apologies if this is a repeat.
The sharpest knife OOB was my KaBar Large Dozier. It would push-c ut newspaper 1 inch from the point of hold.
But if I averaged the knives I have bought from various companies, the sharpest would be Spyderco. On average, they provide the sharpest knives OOB.
That being said, I place little weight on the OOB sharpness. Of all the factors that go into producing a knife: sharpness, alloy, ergos, overall fit and finish, the one I can change with the least effort is the sharpness. And the first thing I do when I get a knife is to fuss with the edge, changing it to suit my personal usage requirements.
