Publication number: 20220241655Abstract: An iron-type golf club head incudes a body, a recessed channel, and a weight assembly. The body includes a striking face, a sole, and a back portion positioned between the sole and the striking face. The striking face includes an upper topline edge and a lower leading edge opposite to the upper topline edge. The recessed channel is formed in the back portion and defines a curved path. The weight assembly includes a weight at least partially disposed within the recessed channel and configured to be positioned in at least a first position on the curved path and at a second position on the curved path. The curved path is defined such that when the weight is moved from the first position to the second position, a first end of the weight is moved closer to the upper topline edge and closer to the striking face.Type: ApplicationFiled: April 21, 2022Publication date: August 4, 2022Applicant: Acushnet CompanyInventors: Takeshi Casey Funaki, Thomas Orrin Bennett, Kyle A.
