Rich,  
 I did heat treat some of it.  The one on the left is treated and the right one wasn't.  Don't know if I did a real good job of heat treating.  Some broke and all at least turn a bit of a pink tint!!
 I will treat more when I get a chance... I like the pinkish look and seems a bit glossier!! 
  cowboy....I have an Ishi stick but not sure I have as much strength in wrist that I need. Or maybe I need to learn more technique than just brute strength. 

   I'm learning when to quit with percussion and begin pressure!! 
   Seems like every one I try, I learn a little more!!!!!
