The top pic shows my indirect percussion tool with a worn out “tip”. I was experiencing a steady decline in the size and quality(?) of the flakes being removed from my work pieces. I started to blame the quality of my rock and then just became frustrated with myself. Last night I changed out the little bit to one that I had salvaged from another tool that had broken and low and behold giant flakes started peeling away. The frustration was gone and knapping became much more enjoyable! I’m hoping Jack Crafty can chime in here and maybe give us some insight or tips on proficiency with indirect percussion. The new tip is about half the size on the business end so maybe that makes a difference, or maybe it’s that it’s just a longer lever?
