GOLF CLUB
An iron-type golf club head is provided with a body having a volume less than 120 cc. The body can include a sole portion with two or more slots extending upwardly into the body through the sole portion into a cavity behind a face portion. A damper can be included in the cavity and in contact with a rear surface of the face portion. The club head can have a maximum CT proximate to the ideal striking location and a CT dropoff of no more than 110 μs at a point located between a first and second scoreline proximate to the sole portion. The club head can also have a CG along the y-axis (CG-y) between 0.25 mm and 20 mm and a CG along a positive z-up axis (CG-z) between 12 mm and 25 mm.
1 . A golf club head comprising:
a body including a heel portion, a sole portion a toe portion, and a face portion, wherein the sole portion extends rearwardly proximate a lower end of the face portion;
wherein the face portion includes an ideal striking location that defines an origin of a coordinate system in which an x-axis is tangential to the face portion at the ideal striking location and is parallel to a ground plane when the body is in a normal address position, a y-axis extends perpendicular to the x-axis and is also parallel to the ground plane, and a z-axis extends perpendicular to the ground plane, wherein a positive x-axis extends toward the heel portion from the origin, a positive y-axis extends rearwardly from the origin, and a positive z-axis extends upwardly from the origin;
wherein at least one point on the face having an x-axis coordinate of −30 mm has a contact time that is at most 130 microseconds less than a contact time at the ideal striking location.
