Etched my Tanaka Gyuto and noticed glitter? This was above the area I thinned, not sure whats going on with the clad but surprised me. Note that there's no texture to the glitter that I can detect, it's all smooth. Prior to the etch I had taken the knife to a hazy polish but never detected any difference in the clad color/contrast. Either way looks like glitter wont go away unless I remove more metal, but it's started to grow on me.
Also for pro-etchers, any advise on how to get the Blue #2 etch a more uniform color? Notice that it's varying shades of dark grey. Did I mess up the prep?
