• a body including a hosel, a heel portion, a sole portion having a sole length, a toe portion, a top-line portion, a face portion having a loft angle of 17-60 degrees, and a leading edge joining the face portion and the sole portion and having a finished leading edge radius, wherein the sole portion extends rearwardly from the leading edge;
• the sole portion having a machined sole portion area of at least 900 mm2;
• wherein the machined sole portion has a plurality of continuous machining scallop lines extending from a portion of the sole portion toward the face portion and having a scallop height and a step-over distance between adjacent continuous machining scallop lines;
• wherein the scallop height is 10-75% of the finished leading edge radius at the vertical midpoint demarcation plane, and the step-over distance is less than 150% of the finished leading edge radius at the vertical midpoint demarcation plane;
• wherein the plurality of continuous machining scallop lines have a machine tool path defining a vertical tool path plane within a path angle from a vertical front-to-rear plane that is perpendicular to a vertical shaft axis plane, and the path angle is no more than 35 degrees;
• and
