In it you can see the reinforced ridge started in copper appear for no reason in steel. the double bladed shakats also seem to lean toward fluted on both sides ?? Haida?? Fluted on one side only and I've never found a connection

appear throughout history in various locations around the world. There should be other threads regarding these knives here somewhere. Steve
