Thread: Tried Some Thing New

My Botan and Mejiro are those pink layered type stones which are very hard. I think I read that they are more desirable than plain white. Maybe for ascetics?
The Tenjyou is pure white and a dream to make a slurry with. The stone does ware away fast though and I read that the white ones cut a lot slower.
My Koma is hard but gives up the goods with a little effort and the tomo is great for making slurry.
Another problem I have is tape on the spine some times makes the blade stutter on the hone. There is no way around that though.

Just a thought Mainaman, if the jnat adds nothing to the slurry then why not hone on glass?
I have tried a slurry with a DMT plate a few times and the edge was poor .
I did think that the Nakayama added a little to the slurry when using Naguras because the Nakayama does ware down slowly in places which I assumed was from rubbing Naguras on it.
I will also try to round a corner of my nagura and see how it works
Thanks for all your advise ..

Glass lacks texture, and is not as flat as a hone.

You textured your base stone too rough. For a finishing J-Nat to work correctly it has to be as smooth as possible, then its own grain does the work on the slurry not some gigantic artificial scratches.

Your base stone may releases some slurry initially when you are using your naguras, but that should be it, when the honing process starts and the slurry is being worked, no new or negligible number of particles from the base stone should be released.

When I say DMT plate im referring to the little DMT credit card ones..
From experience they don't work for me and your explanation sounds spot on but how come many people use them to generate slurry?
Thanks again

The size of the DMT does not matter, they are way too rough to use as a slurry stones. I have a very well used 325 and it works for lapping because it is so worn out, but the surface is still not as smooth as it needs to be. The smoothness comes with making slurry with nagura/tomonagura.
