摘要: A golf club head comprises a loft angle no less than 18°, a striking face, a sole portion, and a top portion having an exterior surface. In an imaginary vertical plane spaced from a face center by no more than 10 mm and perpendicular to an imaginary striking face plane, an imaginary line segment has a length of 25 mm, a first endpoint located in the imaginary striking face plane, a second endpoint located above the exterior surface, and forms an angle θ with the striking face plane between 55° and 65°. The line segment is tangent to the exterior surface at a first point. A second point is located on the imaginary line segment and spaced from the first point by no less than 1 mm. The second point is spaced from the exterior surface by a gap distance that is no greater than 0.15 mm.

摘要: A correlated set of golf club heads is provided. The set of golf clubs has a first club head that, when oriented in a reference position, includes: a first loft angle, a first heel portion, a first toe portion opposite the first heel portion, a first top portion, and a first sole portion that comprises a first sole rail having a first setback length. The set of golf clubs also has a second club head that, when oriented in the reference position, includes: a second loft angle greater than the first loft angle, a second heel portion, a second toe portion opposite the second heel portion, a second top portion, and a second sole portion that comprises a second sole rail having a second setback length that is different from the first setback length.
