bear in mind that there's more to the measurement of sharpness in this experiment than edge smoothness. Edge angle and adge thickness both play a role.
If you want the micro serrated edge for that tootieness in draw cutting, I would suggest taking the egde to a shaving, push cutting smoothness on the strops first so you get the thin cutting edge thickness, then following up by a few very very light reverse strokes on an 8000 waterstone.
I was also looking into two other factors the author of this experiment brings to my own imagination.
The report writes that natural leather with no compound did "little" to smooth ou the edge, and that it lacked "enough" natural abrasive to have a "large" impact on the blade smoothness after the water stones. However, he did not mention whether or noth that little bit was enough to be noticeable aftetr stropping with the compound laden leather strop...
Also, as a note of curiosity, could light acid or etching compound be used in the leather as an ultrafine strop alternative to abrasives? Maybe some ferric chloride as a stropping compound after the abrasive strop, then rinse the blade and finally strop with clean leather?
