I think that is a great idea, but even that has a limitation as depth,,, All things being equal a slight difference in pressure/direction would change the depth of the scratch patterns... Zowada has some great pics
here and there are more pics around the froum by other people that all seem to tell different stories when it comes to scratch patterns... Looking right there, in the Wiki, I am seeing that the $34 Chinese is the smoothest finisher made, but my face says otherwise...
I am just not all that convinced that this "Art of Honing" can ever be very scientific... JMHO
To the OP:
As you can see in those pics, the Chinese stone can be a great finisher, But it requires many more laps then most other stones, which with every lap increases the odds of a mis-cue that messes up a lot of the foundation work...
