Thread: Dead Hone

The current instructions also say not to dry the hone with a fan, which would also dry the surface faster.

There have been other posts about Choseras cracking, but I do not know if Naniwa fixed anything, bad batch, etc.

How are you drying the hones just out of curiosity?

Cheers, Steve

I dry my hones on edge, and flip the edge after a time...on a shelf in a closet.

That should certainly be fine unless maybe your humidity is super low. Even so your method sounds good.

Cheers, Steve

I have the same stone. Do you have any advice that would help me mitigate cracks? I typically run it under water for about 10 seconds, then splash and go while honing. When done, I just clean it and air dry (on edge). Did you do anything different?

Thanks!
