Wow is all I can say about my new water stone. It cut my normal 4.5 hour honing time down to about 35 minutes for each razor. The slurry on the stone was almost instant. But the feed back was epic and extremely smooth with almost zero scratches under the loupe. My Gold Monkey Jinhou got 60/60, 30/30, 15/15, 8/8, and 15 round trips to clean up the edge a bit. Then I performed 20/20, 10/10, 5/5 and 10 more round trips to make certain that the bevel was set using the Naniwa Chosera 600 grit. Next I performed the usual routine on my Gold Dollar 208 which was 40/40, 20/20, 10/10, 5/5, then 10 round trips to clean up the edge. Next I did 10/10, 5/5, and 10 more round trips to make certain that the bevel was set on the 208. When I did the thumbnail test with both razors, it felt like it was going to grab a hold and split my finger nail wide open:
Next I repeated the same routines listed above on the 4K side of my Norton stone twice with no slurry each time to give each razor that little extra refinement:
I also did the same thing with the 8K side of my stone as well:
Next up I did my routine stropping session which was 5 round trips on the stone with each razor and then followed that up with my hanging stropping session which was 10 round trips on the black nylon webbing, 25 on the scrub leather, 50 on the smooth leather and under my loupe, it looked like a brand new polished mirror with a slight haze to it:
Another thing I noticed was that the Naniwa Professional (New Chosera) 600 stays flatter much longer and rinses much cleaner than the Norton stones do and it was also much easier to flatten as well which is a good thing:
All in all I'm very pleased with this stone and couldn't be happier. It was a bit weird using a slight 45 degree angle to hone the entire edge because it's only 8 by 2.75 inches instead of the usual straight on stroke like I use on my Norton 4/8K which is 8 by 3 inches but it was a very enjoyable experience none the less. And today I also noticed that m flattening stone needs flattening and the 4K side of the Norton combo stone is indeed gone. So I will be replacing the Norton combo stone with other stones. I've not decided just yet, but I'm leaning towards other stones besides Norton.
