Hi. I've used Sandvik's 12C27 steel only 3 times, and like the finished product, but have noticed some peculiar behaviour on it's part. When, on 2 occasions, I used PCB powder to coat the blade and protect it from the combination of high heat/oxygen, it was extremely difficult to remove the powder's residue after hardening. Soaking the blade in water did not dissolve the PCB, as it does on all other blades I have used it on. I had to grind it off, and lost one of the blades to over-grinding it too thin. Today, I had a similar experience using foil wrapping, which I had not done with 12C27 - when removing the blade from the foil, I had to literally pull, hard, to peel away the foil from the blade - and it was really stuck on there. Anybody else who uses this steel have similar experience? Thanks, Mike
