Thread: how frequently do you lap?

I have also found that the Naniwa Superstones load up pretty quickly. I 'clean' them by lapping them before each use. I haven't grid lapped them since I set them initially. Same with my Norton combo 4/8 but I don't use the 4 anymore. I rarely touch my coticules or Thuringian and I just got a JNat and haven't done anything to it because it came lapped flat.

Just to illustrate what I mean, when I see this:



Then I know it's time to break out the plate and lap it. I can't recall what I did to reveal that, probably using it to burnish a natural stone or something along those lines. But 5 minutes on the diamond plate (maybe less I didn't time it) and all's flat. If that had been used on nothing but straight razors it probably never woulda become dished like that.

No, I don't mind at all. I have about 40 razors in rotation, most done from bevel reset up ,that I have skipped across those stones.

I lap when I notice a different swarf pattern on the hone when I touch up a beloved razor. I recently acquired a nice hone and as it looked flat, I proceeded to hone a favored razor. I noticed, but didn't think about having to change my strokes to make a more even swarf pattern. Sorta, kinda like a frowning edge. It passed a HHT and shaved OK but not of the former quality.
I then did the pencil line thing and grabbed my coarse DMT and, yes a bit of hollow both edges an deeper in the center. Only a, maybe, paper thickness of depression but suffice to say, enough to make a difference.
How much is me? How much the hone? I am not sure. But, a difference there was.
YMMV!

PS. Not all diamond plates are perfectly flat and so,can affect the lapping effort.

Since I started using the Naniwa dressing stone.. Not very often. Maybe once a year for synthetic stones.
As long as it took me to get the Washita flat that I found in the wilds...probably never have to again. SOB is like lapping a railroad track.!!
I've all but moved over to Nats, their slower than synthetics, but I like sneaking up on a perfect, smooth shaving edge that isn't as harsh as the synthetics.

Adding ten passes from a coti, after a 12k Nani, removes this harshness.
