What’s the difference! An interesting patent application published last week as US Pub. No. 20070135226 titled “Golf Teaching Aid.”

The application describes the invention as:

There is described a golf teaching aid provided with a central body (1), elongate target alignment means (2) projecting from the eternal body (1), a putting alignment bar (12) connected to one side of the central body, and one or more club alignment bars (10, 11) connected to an opposite side of the central body in alignment with the putting alignment bar and substantially at a right angle to the target alignment means. The target alignment means can be an elongate bar extending through the central body. In one form, a curved putting guide (13) is mounted to the putting alignment bar (12) to extend alongside that bar. In another form, at least one of the putting alignment bar (12) and the club alignment bars (10, 11) is pivotable sidewardly relative to the target alignment means (2). At least one of the club alignment bars can also have a curved swing guide (25, 26) extending from an outer end distal from the central body (1). A golfer can use the golf teaching aid to practice various golf strokes using different golf clubs.

Must have been invented by a lefty. Congratulations nonetheless.
