The information contained herein, one way or another, almost always originally came from other blacksmiths. As blacksmithing is so very old, there is not much that is new. Almost every basic method or process has been tried before someplace or sometime. There are about as many ways to blacksmith as there are blacksmiths. Each blacksmith has to process the information he/she receives and try to make it fit their situation.
