    Default Gokumyo 20000 stone

    I have a Gokumyo 20000 stone on it's way. It comes with a 3k/8k conditioning stone. Can someone tell me the purpose of the conditioning stone? Is it for making slurry? Or just for smoothing out the grit? Something else?

    Thanks
    John

    It is used to raise a slurry with the idea of getting multiple grits out of it. Don't use it though. I have a 20k Gokumyo and it has made my Eschers obsolete. I use my 20K just with water 20-25 strokes is all it needs. Sham says it starts to micro chip around 100. Produces such a soft edge.

    Will I need to lap this stone? If so, will my DMT 320 suffice?

    Thanks for your reply

    it is used to clean(condition) the surface of the stone. Mine lives in the box, I use very well worn DMT for the purpose.

    325 will work, but be prepared to spend time, this is the hardest synthetics I have seen. It is great hone IMO.

    Stefan,
    I've seen you use this phrase "well worn DMT" before. I have one and I've used it for honing out chips on razors and lapping my bevel setting stones, but how do I tell when it's "well worn"? Is there an objective, observational or testable method for determining that?

    Mine is may be 3 years old now, it is more like 800 -1000 grit right now as far as cutting speed. I am not sure exactly how this works, but right now this is my favorite lapping and smoothing stone for all my naturals and the Gokumyo. As I said no scratches left after it , and still fast enough to lap stones that are dished after use.

    Diamond is has very sharp corners and tends to make deep scratches. A worn DMT has had all of the high points worn off and is much smoother, but still fast. I have a 600 that I have beat to death and it's my favorite for coarse work.
    One time, in band camp, I shaved with a Gold Dollar razor.

    Can't find a vendor (or even a Google site) for this stone. Suggestions?
