Gear effect occurs because clubfaces are slightly curved (bulge for horizontal, roll for vertical). When you strike the toe, the face rotates open at impact but gear effect imparts draw-spin on the ball, partially correcting the rightward face aim. Heel strikes do the opposite. This is why toe shots often draw back toward the fairway. Modern clubface engineering uses variable face thickness to maximize ball speed across the face while gear effect handles directional correction.
