Thread: Naniwa cracking

Hmm Hans your story is not making me feel good about this.

Leaning more to returning them now.

It's funny when I had them in my cart and was deciding between the two I never even thought of this issue.

Interesting thread. I have the old Naniwa SS 1K, 3K, 8K and 12K stones. Never had, touch wood, a problem with them crazing. I just spray some water on them, hone and when finished wipe dry and set aside to air dry before storing. I do have an old 3K/8K combo stone that likes to warp/cup. Personally I think that is from having the two different grits glued together and you have differential drying going on. It eventually will return to flat but it sure does make you wonder when you first encounter that.

It sounds sort of like marrying a good solid '6'. Does everything that you need it to do but it can't help but make you think, 'Could I have done better?'

I have 6 Naniwa superstones and a 1k chosera They are all about 8 months old. I found a site still selling superstones, so I restocked my older models. All of mine are 20mm thick and all of them are on the old stands. Like eddy79 I soak all of mine for 5 to 10 mins before use. I have no issues with cracking or any damage. None of them have twisted or warped. I can add that the 5 superstones that I replaced were 3 or 4 years old and I had no problems at all. I think there must be a common denominator as to the crazing/cracking. Is the stands the SS were on an issue, or perhaps the differing width (10mm v 20mm) What is clear is that quite few have had this problem and maybe those guys get together and write to Naniwa as a group.

All I can say is ....................

Hehehe. The only thing I dislike about the Nortons is the thirsty 1K hone, and the fact that the line stops at 8K. Maybe one day they'll give us a 12 or 16K. A man can dream...

I guess I can live with the 1K as is, but it'd be nice if they came out with a less thirsty version of that and maybe a 400-ish grit stone that didn't turn to mud.

Because they are tool hones, I doubt that ever will happen.

I sold my 4/8 combo years ago and bought the single grit 4k and 8k. Gave away the 1k to a local guy back then and bought the chosera 1k. Never regretted those moves. The 4k stays in water in a sealed tupperware container. The 8k is splash and go as Norton specifies in the brochure that comes with the stone. One great thing about the Nortons is they are not effected by atmospheric conditions the way these Japanese synthetics seem to be.

I guess that depends on who is doing the honing.
