I have a Nanniwa 12k for finishing and keeping the razors in condition. After honing the edges on the long side of the stone remain rather rough. Is this normal after honing ? I think it is because of the spine going over the stone , but not sure. Looks like the edges are a bit swollen .
I had this now already several times. Also after flattening the stone with another stone or sandpaper grid 400.
anybody familiar with this phemomenon.
I have not experienced a rough edge. Is it possible that you may need to go back for more than a touch up? By rough are you looking through magnification? Because at 12k level your bevel should be like a mirror in my experience.
I suppose too, maybe a piece of grit from your sandpaper stuck in the face of the stone and created scratches and chips in your edge.
No i cant say that i have, I have seen your other post about the Naniwa, But i,m missing the part about the edges look a little swollen? Ty
By the "edges" of the hone, do you mean the corner of the hone defined by the meeting of the horizontal and vertical surfaces?
Have you chamfered those corners of the hone?
Yes , on the long side , between the honing plane and the side
I did not really chamfer them much , just a very tiny bit
OK, if you believe they are rough, then I suggest that you smooth them more. :w
Certainly you should do so if you think it is affecting your blades.
I would recommend going back and watching a Honing video again to compare your situation with whats happening in the video, Ty
yes , it feels like it affects the blade
but I smoothened it already a few times
I think I gonna chamfer it more
You may be biasing the pressure toward the heel and not realizing it. Try biasing the pressure toward the toe for a few strokes and see if that improves the feeling.
You could also be running the blade too far down toward the heel and getting into the stabilizer area or the area of the spine above the stabilizer - if it has one.
Old razors that were honed for decades on narrow hones at an angle also are many times tapered, that is the spines are thicker over the heel than the spine over the toe. If you hone such a razor at 90 degrees rather than say 45 degrees, it will many times produce a 'rough' feeling. It will also cut a different bevel and you'll have trouble bringing the edge up properly. Many times you can see this just by looking down on the spine.

Thx Steve. I check it out.
“it feels like it affects the blade”
What does the edge of the razor look like under magnification?
Post photos of the stone and the blade.
