Thread: Slurry stone question

I got my Naniwa 12K today and Phil from classic edge included an Escher dark blue slurry stone as a freebie for shipping delays.
Now, it is my understanding that the Naniwa ss are fairly soft stones and that thurrys are more or less harder stones.

How will these two stones interact with each other? Wouldn't I just be getting slurry from the nani and not the thurry? How do you guys recommend I use the thurry slurry stone?
My task is refreshing a blade currently.

Hard to say for sure until you try it

But I think you are right the Thuri/Escher is probably harder then the SS,, the colors of the slurry will tell you a ton..

Using any slurry is a learning experience, you have to take the time to figure out if it is advantageous and how to get the most out of it..

In general I start with 20 Pigtail laps then dilute out over the next 10 laps that is just a starting point, each Stone/Hone and the effects of the slurry will lead you along..

I have used turi slury with the Zulu with good success. What I do as not to glaze the Zulu, is to work the turi slury on an Atoma 1200 and then rinsing it with little water in to the Zulu. Just a suggestion in case you don't like the results of the Nani 12 with the turi slury combination. Double O

I'm not really getting any slurry from the thurry from what i can tell, it just seems like I'm getting dark crap when I do laps on the hone with the blade...isn't that swarf? I thought you weren't supposed to get swarf above a 4K (according to the wiki)? I'm especially getting this black crap along the edge of the hone where the heel is and don't know why, especially because I've lapped it flat.

I'm suffering from information overload right now and getting quite frustrated from my first honing experience. My blade isn't sharp enough...it will shave, just not very well, and it won't pop arm hairs off. Do I need a different stone or what's the deal? HELP

Swarf is simply removed metal. If there is none, the stone is not cutting. Can you reference that Wiki page. I'd like to read it in context.
I get swarf on my 12k Shap & even on my most exe Jnat. Depends on how many strokes I do.

Possibly the dark line at the edge of the stone is your area of greatest contact. Not necessarily a bad thing. Just shows you don't need a narrow hone for warped razors as you can direct the contact at will.

Did you finish on water alone ? That would be the way for a 12k synthetic.

Just did a quick test. Escher slurry stone does not seem to release when rubbed on SS 12k.
As a control, I rubbed it on a much harder synthetic stone, and it slurried just fine.

You could use it to selectively lower high spots on your stones, the way Japanese woodworkers use nagura to even out Jnats.
It also seems to raise slurry on 12k like crazy, so if you are into slurrying synthetics, seems to work well there too.
Good luck.

I've tried with thick slurry, thin slurry and just water...still not as sharp as I think it should be. Should i continue and do way more laps? It's not popping arm hairs :c

"If you develop swarf on the 8k, it means you went there too soon and need to go back to the 4k." was the quote that may be confusing me, from page New to honing, Read this - Straight Razor Place Wiki

I believe what the is trying to say is that you shouldn't have to remove so much metal on the 8K if you got it right on the 4K.
Any stone, how fine doesn't matter, should give you swarf if it is cutting the steel.

How can I clean the nani 12K? It seems to load up on swarf rather easily.

Just lap it . OR If it is very superficial your slurry stone might even remove the swarf.
I think that Wiki quote needs reading between the lines. Lemur summed it up nicely.

Look at the pic in the link below & I think you will see swarf on the 8k Norton.
