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!!!!!
