Most everyone, whether on the green or at a putt-putt course, has used a putter. In a round of golf, putters account for nearly 40 percent of a player's shot. Putters come in more variety of shapes and sizes than any other club.

Notable Putt: Hale Irwin drains a 45-foot birdie on the final hole of the 1990 U.S. Open to force a playoff, which he wins a day later by one shot.
