Hello Fellow Smiths - I'm using 1095 for the first time and following clean up after the HT, I have areas of what appear to be almost "blisters" on the blades. These areas appear to be super hard, making it difficult to remove the grinder marks. I used a heat treat oven and quenched in canola oil. The oil may have been closer to 150 degrees instead of the recommended 130. Is this decarb? It seems pretty deep, but does reduce with continued grinding, though I'm getting pretty close to final thickness for these blades.
Thanks for the help!
