A golf club whose face is positioned directly in line with the center of the shaft when placed on a flat surface is said to be square. When the golfer sets up properly with a square club, the face will be perpendicular to the target line.
Most clubs are built in a square position, though some are altered so that the face is open (pointing right of target for a right-handed club) or closed (pointing left).
Even with square face clubs, many golfers have difficulty aiming the club directly at the target. Thomas Golf (www.thomasgolf.com) has solved this problem with its patented aim and alignment technology, built into every driver, fairway wood, hybrid, iron and putter.
