Thread: The dreaded white line

Is there a visual aid for this?

Yes since I've watched every relevant coticule related video on the internet. This dreaded white line was actually coined by Dr. Matt. Best seen and described here

The white line is there because you are not hitting the edge. It becomes easy to see towards the polishing stages of the honing but is there when you are setting the bevel as well.
This is not only coticule specific.

Yea, I get the dreaded white line sometimes too and I only use Naniwa hones. IIRC a few light strokes on a bevel setter put an end to them.

Are we thinking slurry convexed the edge ( using whatever system) and rounded it out so much that when we go to polish were only hitting the bevel planes and not the edge of the edge. We are seeing the original 1k scratches on the bevel. That's my theory. I subscribe to that or Rezdog's fin breaking off.

As to if it's there at bevel set. I don't know. I would need to see some proof because this can develop on the most crisp clean flat bevel. After it's been established.

Being as we are talking about a white line that is parallel to the edge and not along the edge I do not believe we are talking about a poor lay set bevel.

I never get that with mine, but I also only use it as a finisher with at most a very light slurry

Strop it on your hand or do 20 laps on leather is it gone ???

if it goes away with that re-finish and be done

NO ??

Then gently kill the edge and re-finish and be done

If neither of those work then you need to re-evaluate your lower stages

I guess you are seeing a wire edge due to overhoning.

To get rid of it some will breadknife the razor on a cork. I usally strop it a few roundtrips with minimal pressure lifting the spine 30 degrees on linen strop or my jeans. After that 15 roundtrips on your finisher and you're home and dry.
