What happened?
Magnification 200-300x
Edge after Chinese 12 KAttachment 70681
Edge after light stropping on clean leather, about 50 passes.Attachment 70682
What microscope did you use?

Sorry, but i have just Slovak page with it.
And another question: is that edge good?
The answer is: Does it shave good?
I'm starting to learn the high magnifications...looks like there wasn't enough time spent on middle and especially the finishing stones. I say this because of all of the deeper scratches. Chinese stones are very slow cutters and require many passes. Bevel appears to have been set well. What stones did you use and how did you use them?
Keep it on chinese 12 k a little longer see what happens.
Your 'pre-stropping' picture doesn't have the necessary detail to make any conclusion.
I'm willing to bet money that the 'microteeth' are right there and weren't created by the strop.
Was this perfect edge validated with a shave test?
It is possible that the strop added a degree of polish
that made some of the micro scratches visible. Prior
to stropping they might have been invisible in a general
softness that natural hones can give.
The only test is the shave test. All the others
are at best hints, tricks and tools in making a second razor just
like that your previous perfect shaver.
This happens. I believe the edge coming from the Chinese may have given you a false sense of sharpnes.
I like to explain this with my DMT fine. Sometimes, when I set a bevel on a DMT 600 I get positive HHT.
Well, we can all agree this wasn´t because of the extraordinary fineness and abality oft the DMT 600 to finish a razor (haha),
but rather a deceptive false edge. It may be possible that along the way to the finish you created a false and fragile edge
and by stropping you accelerated what was bound to happen anyway.
Another option is that your stropping technique is faulty, or your strop contaminated with some kind of grit (e.g. dust).
I agree with Sham and would recommend you to hit the Chinese a little longer.
You could even try to add one layer of tape and create a double bevel, or microbevel on the Razor
thus giving the Chinese a better chance to erase defects
From what I can see you have used a very high magnification, if so I agree with Gugi, if not I agree with Sham.
@ 100x magnification, it needs a little more work, if more magnification than 100x it is probably good, only a shave test will tell us the truth.
Just my opinion, but there needs to be more time spent on the lower middle grit or 1000. Also,the way I hone is probably a lot different than many here. Most people go up and back on the stone pretty much vertical, which leaves the vertical valleys in the bevel. I have and still do circular motions on the stone and many times do some up and down movements horizontal to the stone but in line with the edge of the blade. The grit now has a chance to work in more than one direction. The grit can rub across the valleys and take of steel and lessen the valleys. By circular motions I don't create valleys vertical in the bevel but rather a series of criss-cross patterns on the bevel. Each tighter grit, leaving less and less valleys than before. Spend more time on the lower, some vertical movement to get rid of the major valleys, and hone on the 12K with some enthusiasm, and include some up and down movement of the razor on the stone not just back and forth the length of the stone. It's hard to explain. If you watch Glen (gssixgun) hone on a video it shows it better than I can explain probably. I've done this years ago on knives, as I was taught by my Uncle Evan Rittenhouse on sharpening, not only knives, but he used it on his straight razor as well and his razor was amazingly sharp. Circular motion is a technique I learned back in the 1960's from those that demanded their knives be sharp enough to castrate calves and really cut when they needed them to.
Well...The first thing I learn from this is to keep away from Vern's uncle!
Second,
From the pictures and Rotovator's statement above I get the impression that the pic is about 20x magnification...with possible digital enhancement. The bevel is in focus with deep scratches, flanked by polished segments thanks to the 12k and stropping. That leads me to believe that more 8k range work is needed to hone out the scratches, and when the surface of the bevel becomes uniform (not smooth but uniform in scratch pattern) move to the 12k until the bevel reaches uniformity at that level, then strop and see what happens.
My two cents.
Peace,
Oh, pardon, i made mistake. Magnification is not 20-300x, but 200-300x.
what stone progression are you using your not getting the lower grit scratchs out
I use these:http://www.fallkniven.com/en/shop/de.../sharpeners/d4
Small Naniwa Combination Stone Grit 1000/3000 - 1000 grit is not good, 3000 yes, sometimes Rozsutec-about 8 000, Moravian Suchacek slate about 8000, Chinese 12 K.
Almost all are natural and slow maybe that´s problem. I think i need something like this: Combination Stones | DICTUM GmbH - More Than Tools
It may be that your Rozsutec/Suchacek, being natural stones, are more like 10k than an 8k. And being slow, it may be too much of a jump to go from the 3k to the others without spending a TON of time working out the 3k scratches. Maybe someone with more experience with your particular stones can speak to this with more authority.
Rozsutec stone is around 6k if your new to honing i would stay away from diamond stones they leave deep scratchs
You should get better results with a medium slurry on the rozsutec to bridge the gap between the 3k.
I have a new Naniwa 600 grit stone and i ordered Norton 220/1000 for better bevel setting.
I know they write that Rozsutec is about 6000 grit, but it is really finer. That is stone from my land and i experimented with it for a year.
I have tried that razor a little and i think it shaves nicely.
