Indeed. Consistency is key for hones to learn on and gather advise for use, IMO.
To glean advise on anything else is a moot exercise as all naturals are different. The KISS factor comes to mind. :D
IMO, Naniwas are fine for the mid-range. I personally favor the 4/8 Norton.
Why? I am lazy! Out of the pond and onto the honing. No swelling from oversoaking, no pile of hones drinking water, etc. Same result for me.
Opinions are like assholes. Everyone has one.
For a beginner and an expert, a 12k Naniwa is a good choice for a touch-up hone and also a finisher to learn on, IMO.
The advantage is it is common and consistent, reasonably-priced. Advise can be given as we all have experience with them....
Mostly! :)
Not much comparable for the educational chore at hand, IMO.
Asshole me! :D
