This is a commission painting on an old saw. It is sealed behind a polymer product called Liquid Glass, and has a strengthening strut down the back so it can be hung on the wall. It was first acid dipped and polished then acrylic paint sealed where the image is to go, before the paint was applied. The shiny finish was amazing.
Another blade in the series is this skill saw blade with a scenic image painted on it using the same technique.
