What’s the difference between a pitching wedge and a sand wedge?
The short answer is about ten degrees of loft. The long answer is that a pitching wedge can be used in a variety of situations whereas the sand wedge is almost exclusively relegated to the task of getting your ball out of a sand trap. A pitching wedge can be used for shots as long as 130 yards when you want the ball to stop on the point of impact. It can also be used for much shorter shots when chipped.
