Abstract
An improved golf putter head having a striking surface comprised of multiple strings, each string having separate and variable tension capabilities, and a multiple position shaft with adjustable shaft angle capabilities on the back portion of the putter head. The striking surface is comprised of individual, parallel, equidistant adjustable strings across a recessed area between the lined striking face and the front of the putter head to allow for full flexing of the lines without interference from the head structure. The putter head has curved ends with grooves to accommodate and align the strings. The putter head has holes with setscrews at each end of the string groove ends to lock the strings in place once the desired tension has been achieved. These adjustable string tension mechanisms allow the characteristics of the putter face to be changed to create a harder or softer striking surface. The adjustable shaft mounting points on the back portion of the putter head allow the putter to be used as a right handed model, a center alignment model, or a left handed model.
