Now look at the 4th picture (Nakayama 1). It's obviously the same part of the blade same magnification, so the unhoned scratches on the body should appear exactly the same.

They do not. Someone is trying to favor the Nakayama. It does only take a minor adjustment of the lighting angle, to make a dramatic difference.

I own a Nakayama myself, and I find it an excellent hone.
I don't own a Shapton, but I'm sure, based upon many testimonies of guys I trust, that it's an excellent hone as well.

I love science and scientific methods, even conducted by non-scientists with crude setups. But I hate it when bias is disguised as science.
On the same note, honing is about sharpening, not about scratching. How fine a hone polishes is only one factor contributing to its sharpening capabilities.

Hi Bart. If i get what it is you are looking at, there is not an unhoned part of the blade. What you are seeing is the weld line between the hard steel and iron
