As the name implies, a golfer uses a sand wedge to stroke a golf ball from a sand bunker, also known as a sand trap, bunker or hazard. Designed in 1930 by Gene Sarazen the short-shafted sand wedge is often the heaviest of the 14 clubs, weighing nearly 40 ounces (1150 grams) with a typical loft angle of 54 to 56 degrees. Though its name and primary function is to skim and bounce through sand particles, it's also used from grass lies for short or high-trajectory shots. The professional golfer can typically hit a sand wedge some 100 yards (90 meters).
