Thread: Naniwa hones

Do the Naniwa hones need to be soaked in water before lapping?

The Naniwa Super stones are not soakers according to the instructions of use, just splash and go.
The Choseras are soakers, but I just splash on my 1k and use it as is with no issues.

I soak my Naniwa SS for 10 min. or so because they seem to swell a bit,

this discovery happened post lapping with a known flat/true blade and the metal removal pattern it was leaving on the stone.

My 8k seems to be the most affected by this condition.

I do not know if this is the 'norm" but it was not untill after this discovery I found gssixgun's post/ video

(if you ask I will go look for it) that he also does a light soak for the same type of reason so it has become my practice.

What pfries said. Me too! Seem to have better results with a soak.

conan,

I too give mine a brief soak - five (5) minutes then lap with DMT325.

Have fun !

Best regards

I just get mine wet and then lap them. But, then, I've never been of the mindset that my stones need to be granite plate flat.

I used to soak mine, both Superstones and Choseras.



Nowadays, not so much...
That 10K Chosera is still working as it has always done, but who knows for how long??

Splash and go I tell ya, splash and go

Definitely NOT!

Neither NANIWA CHOSERA nor NANIWA SUPER STONES are soakers.

They can absorb some water, but they are not intended to soak.
The same is for SHAPTONs ( AKA　 刃の黒幕 【ha no kuromaku】 ).
All these stones are of magnesia bond type.
So the bond can degrade when exposed to water for a long time.

When such a stones are exposed to water for an hour or more the surface become limp and crumbly so you have to remove some with lapping to restore it.

Word ! Don't soak à Naniwa.
