My comments have been strictly about content, gentlemen. There is nothing against the man in what i have said. I have respect for everyone that has posted here. ive read your posts
I was full of slurry there for a few minutes, I feel well lapped now
Contradictions are not hard to come by when honing. If you don't see it, my pointing any out will add no clarity to the subject.
First let's remember that is not a razor bevel. I believe you can tell nothing about the edge condition in these pictures. they are for scratch comparison.
what you are seeing if it is not clear is described in the article. It is a forge weld of hard high carbon steel edge to thicker backing of wrought iron.... We know that a 30k ceramic stone will polish to a high mirror and it will leave very small scratches. You can guess this even if all you have is an 8k
you can see the difference of the kasumi finish of the natural stone very clearly with the naked eye. the naked eye appearance of each type is perfectly aligned with the side lit magnified photos.
The reason one is shiny and the other matte, is the difference in the scratch pattern. They are radically different. There are two things that may explain the dichotomy. Both related to binder as Bart mentioned. The nat binder is weak allowing clumps of particles to be released and easily break down. The synthetic may be releasing clumps of particles; however, the binder "might be" keeping those small particles acting as single larger particles.
