Abstract
Abstract A golf shaft is attached to a removable sphere at a first end portion below an offset in the shaft. The sphere is mounted within a pocket of a top portion of a putter head and seats within a first cavity in a bottom portion of the putter head when the top and bottom portions of the putter head are joined. Set screws located in the bottom portion of the putter head retain the sphere and a half sphere located in a second cavity in the bottom portion seated in place. Retraction of the set screws to the sphere permits movement of the shaft so that its angle with respect to the putter head can be adjusted.
