I've attended exactly 2 blacksmithing workshops. I don't know what would make the metal crack. I've seen the video of them making axes and they chop off a billet and run it through dies to shape it. I wonder if pushing the drift through for the eye could do that or maybe it split when it cooled... I'm curious what happened! Really.
