Just finished this one up. I did not heat treat this blade. I made sure I cooled the steel after every pass so that it would not heat up and change the properties of the existing treatment. I tried hand sanding a few small scratches out when I was done. 45 minutes with 320 grit wouldn't touch it. Sorry about the pictures - indoors with a flash. Steel is from a planer blade (D2), scales are a piece of scrap hardwood flooring, and the pins are 1/8" brass.
