Great example of tool steel, heat treating and what is that tool doing. Craig made a hand tool for the power hammer to forge these little buttons. He grabbed a piece of s7, forge the recession into it and figured it being a red heat let it air cool (a quick anneal.) 20 forgings later it snapped in half. We can see still how hard the s7 was based on the structure of the crack. Lesson today: Crack kills. "Drugs are bad, mmm'kay" #mrMackey #BlacksmithProblems #powerhammer #blacksmith #toolporn
