Why so many clubs?

A golf set is designed in such a way that each club is intended to hit a golf ball to a certain distance at a certain height. The game is simple if the golfer uses exactly the same swing with exactly the same power every time. The shaft length decides the distance the ball travels; while the face angle decides the height of the ball trajectory. In other words a golfer allows the club to decide the distance and trajectory. The longer the club the further the ball goes. The bigger the face angle the higher the trajectory of the ball. All that is required for the golfer to do is to hit the ball consistently with exactly the same power every time.

Golf set

The game of golf is played with 14 clubs. The longest one, the one wood (on the left) is called a driver (10 to 12 degree face). It is used for starting the game on par 4 and 5 holes. The shortest one, the putter (90 degree face) is used on the green for rolling the ball into the hole. The 12 other clubs are used for hitting the ball to fixed distances (shaft length) and heights ( face angle) from the fairway or rough. The idea is to hit the ball exactly the same way for each of these 12 clubs and let the club decide the distance and the height of the trajectory. I find that using 80% power works best for me.
I carry three special utility clubs in my bag: a rescue/hybrid club (iron/wood), a 9 wood (replacing the 3 iron) and a 60 degree lobe wedge for pitching the ball from the rough around the greens.

If I use just 5 clubs (driver, 4-iron, 8-iron, lobe-wedge and putter) I can usually play under 100 strokes for 18 holes. The other 9 clubs allow me to refine my strategy and to cut 6 to 8 strokes from my score.
