Incorrect, all naguras have same size particles, difference is how much they can break down in use.

Nagura slurry does three things, it provides grit (especially with the Mikawa progression), provides lubrication to prevent skipping and burnishing, and it "energizes" the host stone into releasing more slurry of it's own.

the base stone should not be releasing slurry, the point of it is to refine the slurry from the nagura/tomonagura to the finess of its surface. If the base stone will be releasing slurry that will result in boor edge refinement.


Naguras have to be soft enough to release slurry easily, best ones are.

@ OP: you can round a corner on your Mejiro and use that corner to make the slurry it will be a lot easier. Make sure you are not going to rub any sharp edges on your stone , it may get scratched.
