Raising a slurry.

Hello,

How do you raise a slurry on a very hard stone, do you use a diamond grit or a soft slurry stone?

Thanks

A diamond plate will raise slurry from a hard stone. A soft slurry stone will make it's own slurry.
You can then hone on 2 different mediums.

I just use a few swirls from my Naniwa lapping plate (320k) on whatever hone I'm using, the slurry will match the grit.

DMT325 works great for raising a slurry and lapping the hone in one step if you use figure 8's as recommended by gssixgun, bevel edges of a hone, cut down or reshape protruding heel of a blade, just a good multi purpose tool..........well worth the investment.

It just feels right to use my wee Coticule slurry stone on my oh so nice Coti.

Thanks everyone, you guys reminded me of the obvious answer i should have gotten my self. I just made a slurry stone out of the same material.

Assuming you want a slurry from that stone, I think using a smaller piece of the same stone is the best option. Personally, I don't like using a DMT because mine (a DMT325C) leaves scratches in hard stones. I'd bet the scratches don't have a negative effect on honing, but I still don't like them.

As Oz pointed out, the softer stone will make more slurry than the harder one, if you mix and match.
