IMO the photo showed a chip from a stone particle that was too large. Probably from aggressive tomo slurry raising. If you have 3 layers of tape on and the particle was there, you would have the same...

There are many ways to do this. The method your using is one of them. Nagura sets can take you from bevel setter on up to finisher on one stone. You can also get prepolishing stones to use as a...

I lap my stones up to coti. Although many I know stop
at 600 grit. What Im getting out of the scope pictures are some bevel wrecking particles. If you havent already, round a corner of the tomo and...

Many ways to proceed here. Soft touch on the tomo, small slurry, breaking the slurry with another blade first to partially break it, using the shobu with slurry and using the broken shobu slurry on...

Not answering for Alex BUT the edge degradation is happening on the Nakayama. I would look there first.

Generating lots of slurry violently may cause larger poarticles to break off the main stone or tomo. After the 16k, you dont need a large slurry though as a large slurry will set the edge back.

We were typing at the same time there. I would start with a thin slurry and break the last slurry with another blade to make sure it doesnt chip up your edge. These particles can certainly become...

Short lived edges are usually the bevel not being fully set IMO. I would start there (1k) and work the edge till clean of all chips and until it passes the TNT or other test for set bevel. Decrease...
