A putter-chipper golf club may include: a body 110 including a coupling groove portion 110a having a through-hole formed therein; a variable face 120 disposed on one side of the body 110 and configured to function as a putter face or a chipper face; a spring 130 disposed on the circumference of a part of the coupling protrusion portion 120a; and a face cap 150 disposed adjacent to the spring 130. When the coupling groove portion 110a of the body 110 and the coupling protrusion portion 120a of the variable face 120 are disengaged from each other by pulling the variable face 120 from the body 110 toward one side, the golf club may be switched to a putter or a chipper through rotation of the variable face 120.

An iron-type golf club head comprising a topline, a sole in opposed relation to the topline, and a front portion extending from the topline toward the sole. The front portion includes a leading edge, a substantially planar hitting region including a face center, and a peripheral region. The peripheral region at least partially surrounds the hitting region such that the hitting region and the peripheral region define therebetween a visually-recognizable hitting region boundary line including a sole-proximate boundary line segment such that when the club head is oriented in a reference position relative to a virtual ground plane, and in a virtual vertical plane perpendicular to the hitting region and passing through the face center, the sole-proximate boundary line segment is vertically spaced above the leading edge by a distance D1 that is no less than 2.5 mm.

The present disclosure relates to methods for forming a golf club head assembly comprising a golf club head body and a high strength faceplate. The high strength faceplate can be heat treated. After welding the faceplate to the club head body, vibrational waves can be used to relive stress in the weld heat affected zones of the golf club body and faceplate.

A golf club that is used to practice a golf swing. Specifically, the golf club includes a handle and a head coupled to the handle. The head is formed from a first portion and a second portion that are coupled together. The first portion may be formed of a rigid material and the second portion may be formed of a resilient material. The second portion may comprise bristles or some other soft, pliable, compressible material that will not damage a surface upon contact during swinging the golf club. The golf club head preferably has the same shape as a traditional golf club head of the same type. However, the second portion forms the sole of the head, thereby eliminating the potential for damage to a floor surface during swinging of the golf club.

The present disclosure relates to methods for forming a golf club head assembly using a combination of different, but separate heat treatments for the golf club head body and high strength faceplate, and vibrational waves to relive stress in the weld heat affected zones of the golf club body and face.

A golf club set includes at least one first golf club whose loft angle is not less than 46 degrees and less than 56 degrees, and at least one second golf club whose loft angle is not less than 56 degrees and less than 60 degrees. The first and second golf clubs each comprise a face provided with score lines each formed by a groove having a groove bottom and a pair of opposite grooves walls which are inclined at an inclination angle with respect to a normal direction to the face so that the groove width between the opposite grooves walls is increased from the groove bottom toward the face. The inclination angle of the groove walls of the score lines of the first golf club is in the range from 28 to 42 degrees. The inclination angle of the groove walls of the score lines of the second golf club is in the range from 23 to 37 degrees and smaller than that of the first golf club.
