Thread: Slurry stones too!!

Yep, did the same thing with one of my suita's. Great idea with cutting up cheap jnats. I have not run across one nagura that did not produce a fine shaving edge. I just ordered a small black thuri slurry stone that I can't wait to shave off of.

Like so, I did this in 20 seconds. Sharp chisel and light taps is all it takes. It's a dirty rock and I guess folks might recognize the maker's stamp. I picked the worst spot to split it at, I'm gonna lap it tonight to see if I can get to a clean surface.

That led to a lot of disappointing experiences with different types of hones. Escher DB was too slow, Vermio and ILR virtually worthless on their own without making hundreds of laps, CNAT was too sticky etc...

In the early days of Vermio, Keith Johnson (tomonagura) made a Youtube video honing on it. I think that was an honest review. I remember him saying that slurry VS no slurry on Vermio made little, to no difference. Not sure that I agree with that, my experience has been different. I go as far as to use glycerine on a Vermio to push it even further. There is a definite difference.

As for the DB Escher, I own that one too, and yes the slurry speeds it up. Like Vermio, it's a finishing stone. It isn't supposed to cut fast, but to polish and mellow down the edge. Anyway, that's just my experience and my stones. As with all natural stones, no two specimens are the same.

CNAT, I've only tried one. I read there is a big variation between them, so it's hard to make a valid comment. The one I used also gets sticky, but that isn't necessarily a bad thing. A stone that is fine and doesn't get too sticky (jnats and Eschers, some coticules come to mind) can cost high $$$, due to their properties and performance. In my experience, I want the cnat to get real sticky because that's when I know it's maxed out. It's just how that particular stone works.

Kieth was using the Vermio slurry stone, that explains its lack of effect. I don't even use the slurry stone from the vermio on anything because it is of the highest hardness, nothing cuts into it. However, use any othre slurry or nagura and then you will see an entirely different side of the vermio. It can cut fast, slow, fine, medium and course.
I totally agree with you on the stickiness factor.

Seems like the Vermio is very hard , slow cuting stone , that is exelent base stone for all kind of slurry experiments , and pure joy .

Exactly, and the only thing jnats offer as an advantage is simply increased speed at which this all happens. And of course the speed in which they cut without any slurry stone is exponentially higher.

Well Jnats are unique and top of the top - edge of the blade , tip of the spear and ect .
i was thinking that with slurry stones from diferent stones you can get the effect of the brazilian hone - hard base with more neutral qualitys and fast rubber stone for nagura .

Got the Naniwa 800 and dressing stone in today. I went to cut a piece off the Naniwa, and figured a wood blade would probably get the job done even if I had to sacrifice the blade. Well, it kinda did - 2/3 of it before it was just too worn down to cut anything anymore. The piece broke off during blade extraction, but that's OK. A slurry stone doesn't need to be a perfect rectangle.

It turns to mud kinda like a piece of coticule. But cuts a hell of a lot faster. Almost as fast as the 800 grit hone itself when turned into a slurry on my PHIG. Could easily be used for setting bevels, not so effective for chip removal I think. But that's OK because I still have 7" of Naniwa 800 grit hone that abrades steel scary fast for something that feels like a ceramic tile.

Still feeling out the dressing stone. I got hung up on getting a new blade shave ready so I didn't really play with it much.

You can get a carbide blade that will fit in a hack saw frame for about 5 bucks, sold for cutting tiles.

Or you can use a hacksaw blade, it will trash the blade but should make a single cut. I have cut small pieces from natural stone with a hacksaw blade.

I like your style, rock on…

I seriously considered the carbide blade option. But that would've required a trip to the hardware store. Which would've postponed playing with hones. And we can't have that.



So I used what was lying around.
