Thread: Same edge, same spot, same magnification, different light...

I'm sorry if this question falls into the "outside of the scope of this thread" realm, but without getting too deep into it.. Just wondering if you're creating the secondary bevel angle by putting two layers of tape on the spine? That's all I'll ask.. promise.

The razor was honed with the following progression:

(Without taping the spine)
DMT 1200 (till it popped hairs)
Naniwa Chosera 5K (till the TPT-feeling maxed out after about 20 laps)
Naniwa Chosera 10K (20 laps)
Nakayama (40 laps)

At this point I test shaved. The razor was rated 21/30 on my personal razor performance sheet. (I've attached a PDF-version, the first column contains the detailed score)

That's certainly within the domain of shavereadiness, but I wondered if I could do better.
Two days later, I added two layers of tape to the spine, did 8 laps on the Chosera 10K. This created the secondary bevel. After that I did 30 light laps on the Nakayama, which did not noticeably widened the seconday bevel. I removed the tape, stropped and went to business.
The results are in the second column. I had a sightly better shave. I always have better shaves with putting a secondary bevel on that Dovo. I don't know why. It's not the same with all my razors: some benefit from a secondary bevel and others don't. Even more puzzling is the fact that it really differs how I make that bevel. I could have produced the same secondary bevel with only using the Nakayama. (It's a bit like sanding down a hard wooden edge, the first strokes are the most productive, with the broadening of the bevel the action slows down exponentially) But the resulting edge would have performed differently. Some hones seem to be really excellent for polishing, and others for refining.

Now you know why I stated there's a lot to be said about this topic.
I'm only at the verge of this. (yes Mr. Citron, me likes wordplay too)
