This is a great idea. You may count me in with a DOVO best carbon and a DOVO INOX stainless. Both are 5/8". Both are in great shaving form with no micro-bevel.

COMMENTARY and SUGGESTIONS: My research on razor blade manufacturing reveals a three bevel process of ~325, 550, and 800 grit stages. Of course they use coatings which fill-in the scratch marks and smooth the final edge. Each stage is at a slightly higher angle. This is not what I would suggest with this exercise. The SR really just needs the final grit to create the micro-bevel, typically 8K or finer. My experience with micro-bevels is similar to Lynn in that I have tried with and without and obtained comparable results. However, I think the micro-bevel approach may have merit for first time honers in that it almost guarantees that you are hitting the edge the full length of the blade. You still need to lay down a solid primary bevel before applying the tape. I will also skip the CrO to make sure that is not a variable. Here are the steps that I will perform.

1) Create the primary with 4k, 8K, and 12K stones (I rarely need the 1K), using no tape

2) Apply one layer of tape, then 30 or more laps on the 12k until the micro-bevel is clearly visible under 20X loupe.

3) Strop for 60-80 laps on leather, remove tape, HHT, then shave test

4) Report back on the results as WORSE, EQUIVALENT, or BETTER when compared to the single primary.
