Chosera 1K As Natural Stone Smoother

[raccoonandbrush]

You know how sometimes on natural stones there are some rough parts? With a natural stone, you need it to be as smooth as possible. I originally used a DMT 325 to smooth out the stone. It could work, but it could also scratch the natural, as I found out. I recently started using my Chosera 1K to do the smoothing, and it works great! It seems like in no time, the part that was once rough, is now smooth. Now I wouldn't recommend people to buy the Chosera 1K for the sole purpose of smoothing a natural. If you are also going to use it for bevel setting, than use it for smoothing too. Whether it's an Escher (especially the Eschers that are all scratched up), Coticule, J-Nat, Chinese 12K, Charnely Forest, the Chosera 1K will make any of them as smooth as they are going to get.

Edit: At Chef Knives To Go, they sell a slurry stone sized Chosera 1K. So for the people who don't have the full sized one, they can get the benefits of using one on a natural by buying the slurry stone version http://www.chefknivestogo.com/ch1kgrslst.html

Sounds like it works well. After that do you use a rubbing (slurry) stone of some type to further smooth out the stone(s)? I do something similar but lap up to 1.5K using wet/dry sandpaper then use another natural stone to further smooth out the stone.

No, the stones do not need anything else after the 1K. The really cool thing about the Chosera 1K is that it's a very quick cutter, both in bevel setting and natural stone smoothing, and is also very smooth. I used it on an Escher I just got. After using the Chosera 1K on the rough spot, it felt just as smooth as the rest of the stone.

I also use this method and it works great, I also keep my stones flat by rubbing them together.
When I got my JNAT I lapped it flat on sandpaper up to 600 grit, followed by chosera 1K, coticule and using the slurry from the coticule on a CNAT. After that my JNAT was completely polished and flat.
The Japanese use the 3 stone method to keep their stones flat and smooth, 3 stones because when you keep rubbing 2 together one can become convex and the other concave and by using 3 stones you eliminate that and all 3 will be flat (concave X convex = not good, concave X concave or convex X convex = flat).

Been doing this for a while, except I also use a 3k C after that, then a BBW. I usually stop there, and I use the BBW after every honing and sometimes during.
The 3 stone method can, allegedly, leave all stones slightly convex.
I check flatness on each stone in 3 places in each direction with a Starrett straight edge.
