A sand wedge is a type of golf club with a specialized design intended to help the player play the ball from soft lies such as sand bunkers. It has a loft of about 56°, and about 10° of "bounce".
The pitching wedge is not the only type of wedge available. The three other types are sand wedges, lob wedges and gap wedges. Each of these types of wedges have different degrees of loft, and as a result, are used for different purposes.
The sand wedge has the widest sole of any wedge, which provides the greatest amount of bounce, allowing the club head to glide through sand and avoid digging in.
Lob wedges, known for being one of the shortest-hitting clubs and providing the most loft on a shot, are used to produce shots with a very high arc, and are most often used for shots over hazards and other obstructions.
The gap wedge, also known as an all wedge, is a wedge used to hit a shot with higher and shorter trajectory than a pitching wedge and lower and longer trajectory than a sand wedge. The name derives from the club's design to fill the "gap" between sand and pitching wedges.
