Just got my Naniwa SS 12k in the mail today, and have fallen in love with it. My razor has a beautifully polished sticky as glue edge which is a noticeable step up from my norton 8k which i thought was good enough... until today! TBH I was under the impression after purchasing this stone that the improvement would be minuscule and I had fallen for all the glitz and glam of fanatic perfectionists, but I have thankfully been proven otherwise :o
I would also like to add to the praise by saying that whoever said they felt this stone was made for straight razors, I'm with you 100%. My blade seems to stick to this stone like glue while honing. Not sure if that's normal (yes i lapped 3x grid) but I have to say I like it very much and didn't want to stop honing because it felt so good.
A super stone for a super edge :D
