Stealther,

Look at any uncoated blade that is differentially tempered or hardened. There will always be a demarcation between the harder and softer crystals, even if they're both the same name on paper. You can see it on the larger SR-101 blades and you can see it on handmade blades with such a temper. Can you see it on the Scrapper 6LE?
