You know what... Today I was just touching up my D4 VG-10... For about 2 hours... When I realized that the midsection of the edge doesn't seem to be getting sharpened.
Toward the tip of the blade, the edge is EXTREMELY sharp. I look in the light, and there is no shine whatsoever, and it splits the hell out of hair. Same story with the edge towards the kick.
However, the midsection just doesn't seem to lose its shine. It looks perfectly fine, but when I do a quick strop on my pants to wipe dust off, it's as if I'm knocking down little bits of the edge; the shine comes back. So I went for another hour... Same story. Toward the tip and toward the kick: perfectly sharp. In the middle.... Shine. It's still quite sharp; I just don't understand why the shine won't go away.
Here's how I'm doing it, btw:
1. Reprofile on a DMT XC Whetstone (6"x2") with a DMT Aligner clamp guide (angle setting: 4)
2. After reprofiled, get rid of burr and deep scratches on the bevel using DMT F Whetstone (6"x2") using the same angle setting with the clamp.
3. Flip my Sharpmaker upside-down and place the white stones on, cap of the SM taken off (it happens to be the same exact height as the DMT stones). This is just to further polish the bevels; no major sharpening going on here.
4. Now for maintenance, I take the white rods and place them on the mount of my DMT stones. It's lower, so the angle is greater, and I'm putting a microbevel on the edge. And I just keep going 1-1 stroke each side. It is a microbevel, so I'm certain I'm getting the edge.
So I just don't understand why that middle part isn't losing its shine. Any suggestions?

I clean them when I see enough metal on the rods... Probably once every 20 minutes. I use 2 corners of each of the rods. I use one rod for one side of the blade, and another for the other (one at the left of the mount, the other at the right so I don't have to keep moving it). I do it for about 10 minutes for each side of the triangles, so 2 sides = 20 minutes. Then I rinse. Every so often, I use Windex to clean em good.
