The full shape of how a shaft's stiffness changes from tip to butt — where it's soft, where it's firm, and how the transition between those zones is built. "Kick point" is the marketing shorthand for this same idea: a single word (low, mid, high) standing in for a curve that actually has dozens of data points. The two terms get used almost interchangeably at retail, and that's fine for a quick conversation, but they aren't quite the same thing — kick point names the location of the biggest bend, while bend profile describes the whole curve, including how sharply it bends there versus gradually. Two shafts can share a kick point and still feel completely different if one ramps into that bend abruptly and the other eases into it. Fitters who actually plot the curve (see EI Curve) are looking at the bend profile, not just reading off a kick-point label.
