I learned to hone on Naniwa's (1,1,3,4,8,12 set), learned how to use the Norton 4/8, and learned the Shapton GS (1,4,8,16,30) stones. I sold off my Nani's and Norton & now have added 220, 500 (only use those on knives as I am a maker) & 2K to the mix. I have found that there is absolutely nothing I can't hone on Naniwa CHosera 1K, shapton gs 2,4,8,16 (or G20) followed up by a natural thuringian. This is the edge that I like, semi "crisp" & smooth.

I do not recommend the 30K until you have literally mastered your stones. I have found that less than 3% of the razors made can handle that fine of an edge and it's an edge that I personally don't care to shave with.

I've had those stones for about 5 years now and show little to no wear on them. It may appear that there is little material on the GS stones, but remember that they are like a ceramic & wear very little. I most likely cause more wear on them cleaning them up than actually using them.

If you decide on the GS stones, feel free to contact me any time!
