Publication number: 20240082659Abstract: A ball striking device, such as an iron-type golf club head, includes a face having a ball striking surface and a body connected to the face. The body has a sole surface extending rearward from a leading edge of the face, and a toe surface extending rearward from a toe edge of the face. The sole surface configured to confront the playing surface. The iron-type club head may have an elongated channel extending from a heel side in the sole member to an end point within the toe surface. The elongated channel is recessed from the sole surface and toe surfaces and is spaced from the leading and toe edges of the face. The iron-type club head may also have a plurality of weighting elements that are adjustable by the user.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Matthew Robert Daraskavich, Jamil Jacaman, Matthew Brian Neeley, Michael R.
