Hey Bandit, you can get the same shape and look just by leaving the sap wood on the back at the tips, then carve that sap wood all day long on the tips to get what ever shape you want. I seen that before and looks amazing. I would do it myself but honestly, I just quit chasing heart wood rings all together anymore and do sapwood backed osage. Reasons being: It works, not many folks do it because its always been done the other way, making me kinda unique, I'm lazy and this way is faster, and I am less likely to damage the back on thin ringed osage. Good luck kid, your doin it right.
