God's Chemistry Set: As Iron Sharpens Iron

Sep 22, 2011· Pure iron is soft and carbon steel can be as much as 1000 times harder than iron. Iron in those days contained varying amounts of impurities and was of different strengths. Sharpening is defined as the process of creating or refining a sharp edge to an appropriate shape on a tool or implement designed for cutting.
