Ihave a 54-11 (bent to 55-12), 58-12, 60-07 and 64-07. I use the 54,58 and 64 for various sand shots and from grassy lies for pitching and chipping. I use the 60 for tight lies within 50 yards and hard packed bunkers. If you have a 56-12 vs a 58-12 as a sand wedge.. the 56 would require less effort to extract out of a bunker.
A54-degree wedge is considered a sand wedge and is used around the green and out of bunkers. A 54-degree wedge is ideal for golfers who have a 58-degree
