Thread: Slurrying synthetic stones?

I usually use a light DN 1200 slurry off every stone, I lightly lap flat/clean before every session and just leave it on top, I personally think it speeds things up to some degree and maybe a tad smoother honing on it.

Jnat users know that slurry can mellow an edge very favorably.

I have one jnat, a nice deep strata Hatanaka with a little iro in it, that will give you an aggressive edge with my usual thin finishing slurry. The razor will shave as smoothly as any edge, but if you're not really careful, it likes to give you a little 'love bite' just to get your attention. A thicker slurry eliminates that and is still keen and smooth.

Cheers, Steve

Natural stones: Yes on the slurry at all levels, higher the "grit", the less slurry I use.

Synthetic stones: NO, I only use slurry on bevel setting stones of 1K or below. You are just wasting stone and time on 4k & higher.

Can synthetic slurry cause a haziness on the bevel?

Just like Natural stones leave different finishes so do Synthetics

The Naniwa SS most certainly can find a Hazy finish the Shapton GS not so much

ie: Just like Natural Stones are different,, so are Synthetic hones

The more you play in the mud the dirtier it gets LOL

Aww... so I am using the Shapton pro stones at the moment when this happened, so are you saying it is possible that using synthetic slurry for an excessive amount of time could be the cause of the hazy finish?

I have never had this happen with my SG stones!

I can't say

I have used the Shapton Pro set maybe 4 times in the last 10 years at the meets


Here is what I can tell you about using slurry on all Synths

Start without, then introduce a light misty slurry to the mix, and see what happens if you are getting positive results continue with the experiments if the edge slips backward introduce more water and experiment more...


The really bad news is that the combinations are endless, you can adjust and tweak for years hehehe maybe that is good news

LOL about the bad news! Now that I think about it I was using the Shapton glass diamond lapping plate which is very very very mellow and recently I switched to using the DMT325 because it raises more slurry probably too much slurry? This little hazy thing didn't start until after using the DMT325, this didn't dawn on me until right now!!! I'm an idiot lol . I will refresh the surface and wash off the slurry for now...Thank you

I use some slurry during the initial and mid-range progression. Usually just leave some on after lapping the stone then it gets washed away as I wet the stone further into the process. Once I reach 8k or so I leave the slurry out of it and its just water until its finished. With naturals its slurry all the way until I begin the finish and then its just water. I am sure that using slurry can be handled many different ways so feel free to have at it.

Yeah I think I was creating enough slurry to make mud bricks lol! Causing more problems than helping...

Thank you
