摘要： A golf practice putter includes a putter head coupled to a lower end of a shaft and having a putter face and a hitting member selectively coupled to the putter head. A through hole is formed in the putter head to be stepped such that a fastening bolt pass through the through hole upwards from a bottom face of the putter head, and a cutout portion is formed in the putter face corresponding to the through hole to open a portion of an upper face of the putter head in a hitting direction. The hitting member is formed in a shape of a golf ball, and a seating face seated on the upper face and supported by an edge of the upper face and a support face are formed to be stepped in a bottom face of the hitting member.

摘要： A variable golf putter is disclosed. The variable golf putter includes a putter head coupled to the lower end of a shaft, the putter head having a head hitting surface, and a hitting member selectively coupled to the putter head. The hitting member has various hitting surfaces, whereby it is possible to perform putting practice in various manners. In addition, the hitting member and the hitting material made of a material different from the material of the hitting member are formed integrally with each other, whereby it is possible to provide various hitting sensations and thus to efficiently perform putting practice.

摘要： Disclosed is a golf ball marker having a clip part. The golf ball marker includes: a clip part including a curved elastic body elastically deformed while a curved shape thereof is reversed in response to an external force applied thereto, and a pressing piece connected to an end of the curved elastic body to be spaced apart from the curved elastic body or to come into compressive contact with the curved elastic body, the clip part being selectively attached to/detached from a pocket, a belt, a visor or head and used as a marker; and a fixing portion protruding from one side of the clip part to fix the clip part to a ground of a golf course.
