Hi Mrjin

Thanks for the pictures. In the original upload, the cracks become more clear to see. I am really sadly amazed that this has happened to your new stone as I have had zero problems with the new set I got from Taidea. I wonder if we treat our stones in a different way? Personally, I hone under a dripping faucet. After use, i lightly lap/clean the stone, dry it with a towel and store it in a dark closet at room temperature.
