Erich, I would venture that the law of diminishing returns applies. That is, the benefits of the unicorn profile is best observed on a cheap or poorer edge-holding blade, with less benefits seen in the premium blade. I posted early on my success in buffing a 20 degree bevel on a set of boxwood Marples. These are wonderfully light in the hand, but held an edge for exactly 1.5 shavings. Post-buffing, the edge was excellent. I was not looking to see exactly how long, but there were very significant gains. I have not attempted to buff Veritas to the unicorn profile (largely because the edge-holding is excellent anyway), but have buffed to hone a dulling edge, and that did leave a superior sharpness.
