Thread: Natural equivalent to a 12k Synthetic

I consider my PHIG stone to be approximatelly 12K and I am very happy with it.

Not many natural stones will go over 12K level.
You can use a Thuringian, this will be the most consistent near that fineness.

Japanese stones will be higher than 12K but they vary a lot.

Coticules are 90% of the time not near 12K.

Whole lotta high grit numbers being tossed out there for natural stones with not one shred of proof..

Next thing you know every Newb will add 2k to your numbers and be calling it gospel..


The fact of the matter still is that Grit numbers are only accurate within each synthetic series of Hones, a 8k Naniwa SS doesn't even relate to a 8k Shapton.. I fact if you want to get real technical there is a difference between a 5k Naniwa SS and a 5k Naniwa Chosera...

The only fact is that a 12k Naniwa SS is a higher grit range then a 8k Naniwa SS other then that it is all conjecture and opinion.. When you start giving grit numbers to Naturals then you have stepped over to Myth...
