Does a wedge replace a sand wedge?

There are primarily 3 types of wedges, Pitching, Sand and Lob. A Pitching wedge has about 46-48 degrees of loft, a Sand wedge has about 54-56 degrees of loft and a lob wedge has about 58- even 64 degrees. Depending on player preference they can have low or high bounce which can assist getting out of the sand and help when playing certain types of course, if you have a low bounce club on soggy turf you may go under the ball easier, not getting proper contact. There are also gap wedges which are designed to fit between the Pitching and Sand wedge, at about 50 or 52 degrees.
