Thread: Naniwa cracking

Bought the naniwa pro set and I see my 3k starting to craze..... should I return my 5 and 10k? I would hate to see them crack and become useless...

Thoughts, opinions, remidies?

Numerous threads on this. I have 1k 3k and 5k Choseras. I make a point of not soaking and drying them slowly. The 5k, which is notorious for checking, is doing fine with this slow drying so far.

My 5 and 10k choseras are crazed. So far they work fine. IIRC holli4pirating had his 1k chosera crack/craze must be 5 years ago. AFAIK it is still fine for honing razors.

So I shouldn't be worried about this?

I have contacted the vendor and I can return the 3,5 and 10k.


If the cracking is not detrimental I will keep the new pro stones but if it willing be in the future. I will return and pick up the new super stones.

i had two naniwa pro 5k (from different vendors) and both cracked after a just a few months. i knew they are prone to cracking and therefore used them carefully. but still...

as a replacement, i bought a naniwa super stone 5k. it behaves as it should. i have never had any problems with my naniwa pro 400 and 1k.

regards,
hans

Has anyone seen crazing transition to actual cracking?

I have three Nani superstones that I bought about 4 years ago and haven't had a problem. I have 5k,8k and 12k and they get lapped with a DMT as needed. I take Glen's(gssixguns) advice and soak mine a little before use but not long,maybe a minute at longest. I would return yours(the whole set) and get a new set of superstones to replace them.

Yep you carnt go wrong with super strones

I had no sign of crazing in my 5k until recently. Since this happened to coincide with wintertime and relatively low humidity in our house, I'm going to start storing at least my higher grit Choseras (2, 3, 5, and 10k) in a humidity chamber.

It can't hurt and it won't be any sort of inconvenience.

Hmm...I dunno. Looking at the humidity here, up north around the Great Lakes, and Japan, I don't see a very wide variance. Im sure it gets a bit lower up that way, but still such a strange phenomenon...

I wonder if there's another environmental factor that could be responsible?
