Abstract: A golf putter having a lie and offset adapter for selectively setting and/or adjusting the lie and offset of the putter. The adapter may comprise a spacer having a lower socket extending from a first end along a first longitudinal axis and a second socket extending from a second end along a second longitudinal axis. The length of the spacer and the orientation of the sockets are set to provide the desired lie and offset of the putter. The golf putter has a head with a face for striking a golf ball, a lower shaft segment and an upper shaft segment. The head is connected to a lower shaft segment which, in turn, is attached to the lower socket of the adapter. A lower end portion of the upper shaft segment connects to the upper socket of the adapter. Alternatively, the open end of a hosel, which extends from the putter head, may take the place of the lower shaft segment. The lie and offset of the putter are selectively set during assembly by installing an adapter configured for the desired lie and offset.
