There is little consistency in labeling gap wedges; most manufacturers simply label the wedge with its angle, optionally including additional information about the amount of bounce (sometimes the angle measure, more often a series of one to three dots indicating "low", "medium" and "high" bounce). Some manufacturers call it an "Approach", "Attack" or "All" wedge, labeling it in these cases with "A". The Karsten Manufacturing Company, maker of the Ping brand of golf clubs, favored the use of "U" for "utility wedge", but currently only uses this label on wedges sold in matched sets; most individual Ping wedges are currently labelled with their angle. It is actually uncommon to find a gap wedge labeled "G"; Adams Golf, Cobra, Mizuno, and Wilson are among the few manufacturers that do so.
