If my tip was too hard I would "tenderize" it using a four way file. Still a great tool to have. I would lightly pound the tip too soften it. It worked. Then use a tip tool (Butera's, then changed to the round disc later) to abrase the tip. And cleaned up the mushroomed tip edges with extra fine sand paper. Prefered Champions but used Kamui later.
I guess I'm as old school as it gets.
