Thread: Jnat questions

I am fairly new to jnats and have a few questions or thoughts I figured I might enjoy feedback for.

I read that most jnats have very similar particles sizes?
Is this true? Are harder stones finer or have smaller particles or flakes generally speaking?
Softer less compressed stones particles size vs hard highly compressed stones particle size?
Or is it more about softness / hardness and how easily slurry is released that determines the fineness or coarseness of the stone?

When the slurry get worked, it breaks down and gives finer results?
On softer stones fresh slurry is released by the stone itself, but on harder stones they don’t self slurry easily or at all? So you can refine the slurry without other interference for very fine results?

I also read about hard stones scratching the blade, is it problematic to hone on water only on very hard jnats?

I’ve read so many different things on various forums I’m not sure how to deal with everything. I know it will be a trial and error thing.

I was told to be careful with naguras not to scratch the base stone, but then after the naguras they speak of using a diamond plate to make tomo slurry. Wouldnt the diamonds also leave some sort of scratches, or is that a non issue?

Does it make sense to use a softer tomo like 4 - 4,5 hardness to make slurry on a 5 awasedo and work that slurry from the softer tomo until it gets finer?
Would the slurry from a 4 or 4,5 break down easier than a 5?
Or do they both break down the same way, or is a 5 finer to begin with?

Because i have a few harder stones mid 5 or so, when using a diamond nagura i can feel some scratchy particles get released and microchip my blade, atoma 1200.
Has this happened to someone, i have it happen on a few stones, not all?

I was thinking about experimenting next time with a harder lvl 5 basestone awasedo, go thourgh a full nagura progression and finish by using the diamond plate on another stone maybe a 4,5 hard one and transfer slurry from diamond plate to my lvl 5 basestone, so I dont scratch the base stone and I have a bit softer slurry to hone with?
