Abstract
An iron-type golf club having selectively machined portions and attributes, including a machined sole portion and/or a machined leading edge portion. The machined portion(s) include continuous machining scallop lines having a scallop height and a step-over distance. The scallop height is 10-75% of a finished leading edge radius at a 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.
Claims20
An iron-type golf club, comprising:
- 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;
- the leading edge having a machined leading edge portion area of at least 50 mm2, wherein the machined leading edge portion area extends throughout at least 25% of the sole length and contacts a vertical midpoint demarcation plane;
- the face portion having a machined face portion area of at least 1800 mm2;
- wherein the machined leading edge portion area is adjacent the machined sole portion area and has a plurality of continuous machining scallop lines extending from the machined sole portion area to the machined leading edge portion area;
- wherein the plurality of continuous machining scallop lines have a scallop height and a step-over distance between adjacent continuous machining scallop lines;
- and
- 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.
