I feel like I have stepped into the middle of an argument here.

Personally, I use 0.25 diamond and 0.1 CBN to add a tiny bit of convexity to razors that I have honed on Shaptons and/or the Gokumyo 20k and I find this improves the keenness and longevity . I find I can touch this up once or twice with the 0.25 diamond before I need to narrow the bevel a bit by dropping to the Shapton 8k/16k. To me, this is consistent with the "less is more" concept since I only use paste on a good edge to make it better, never on a poor edge to try to make it good. Also, I find 0.5 micron diamond too aggressive. FYI, my other razors are Coticule honed, always Unicot, never pasted and touched up on the Coticule.

That said, I would like to think I have shown that stropping on submicron abrasive only abrades the last few microns of the edge. The key point is that the equilibrium "shape" is produce fairly quickly and after that, very little steel is removed. In other words, less is already alot and more is not much more. My only reason for entering this thread was to offer an explanation for the OP's observations and Glen's earlier experiment.
