In the pictures you can see a bold and very clear line of demarcation. It is close to the edge which could be the result of years of sharpening. Look at all the edge nicks. The steel is cleanly flaked off and not crumpled or bent. This blade appears to be San Mai construction which is a hard steel core with softer steel cheeks. An inserted edge if you will. There is some cloudiness above the demarcation line that is probably from the heat treatment. If it was just a folded blade that had a heat treated edge you would only have the darkened zone along the edge but not such a strong and defined line of demarcation.
