The first warning was subtle. As I lifted the initial row of picks off the CNC table, I could feel the tips rock slightly against the Kaotic base. That shouldn’t happen. A quick press of the thumb at the seam—pick braced between middle and index finger—and the tip folded over. One bad mix, maybe. Then the second poured row did the same thing.
