Abstract
A new golf club face design is disclosed in which different regions of grooves are provided in the vertical direction of the club face to impose different roll/bite characteristics on a golf ball depending on where the golf ball contacts the club face. In one embodiment, the golf club face has three characteristic regions of different types of grooves in the vertical direction of the club face. Different irons within the golf club set can also have different characteristic grooves in the three defined regions of the club face.

A golf club head, comprising:
- a club face having upper, lower and middle regions of grooves, the regions oriented relative to each other in a generally vertical direction of the club head, each of the three regions having grooves with different cross-sectional configurations.
A golf club head, comprising:
- a club face having upper, lower and middle regions oriented in a generally vertical direction of the club face, the upper region comprising a roughened surface, the middle region comprising square-v grooves, and the lower region comprising square grooves.
A golf club head having a top edge and a bottom edge, comprising:
- a club face having upper, lower and middle regions of grooves comprising generally parallel crevices, the grooves of the upper region being oriented nearer the top edge than the grooves of the middle region, and the grooves of the lower region being oriented nearer the bottom edge than the grooves of the middle region, and wherein the grooves of the upper region have a v-shaped cross-sectional configuration, and the grooves of the middle region have a square-v shaped cross-sectional configuration.
A set of golf club irons, comprising:
- short-range, mid-range and long-range irons, each iron having a club face, each club face having a top edge, a bottom edge, a first region of grooves, and a second region of grooves, the first region having grooves oriented nearer the top edge than the grooves of the second region wherein:
- the grooves in the first region of the short-range irons have a cross-sectional configuration different than the grooves in the second region of the short-range irons, and
- the grooves in the first region of the mid-range irons have a depth different than the grooves in the second region of the mid-range irons.
A set of golf club irons according to claim, 24, wherein
- the upper grooves of the short-range irons comprise a roughened surface,
- the middle grooves of the short-range irons are normal square crevices,
- the lower grooves of the short-range irons are deep square crevices,
- the upper grooves of the mid-range irons comprise a roughened surface,
- the middle grooves of the mid-range irons are normal square crevices,
- the lower grooves of the mid-range irons are normal square crevices,
- the upper grooves of the long-range irons comprise a roughened surface,
- the middle grooves of the long-range irons are normal square crevices, and
- the lower grooves of the long-range irons comprise a roughened surface.
