I have a knife Ground from a bar of san mai. It is rod iron with a 1080 core. I ground it down and hand sanded it to 320 than hted it. when I pulled it out i noticed that it had bad pitting in the 1080 core. What causes this, is there something I can do to prevent it? I hate samding it to 320 only to have to start all over after HT.
 
I have had that happen to me ? not sure what causes it ? maybe getting to hot ? just a guess .
