“The CG15 was among the last Cleveland wedges with the aggressive pre-2010 square grooves, offered with the new S constant-width sole or the low-bounce DSG grind, in Black Pearl, Satin Chrome or Oil Quench. A players/tour-milled wedge with legendary spin for its era, cheap and still bites used.”

The CG15 (2010) is remembered as Cleveland's last square-groove wedge — the final refinement before the USGA/R&A's new groove-configuration rule took effect for tournament play from January 1, 2011. It combined the Zip Grooves debuted on the CG14 with an added laser-milled face texture (four calibrated texture lines between each groove, cut right to the conforming roughness limit) for extra spin consistency, plus a choice of the new constant-width 'S' sole or a lower-bounce DSG grind, offered in Black Pearl, Satin Chrome or Oil Quench finishes. Reviewers at the time called it gentler on golf balls than rival wedges of the era (allowing a ball to survive 18-36 holes without heavy scuffing) while still spinning shots back hard on full swings — widely regarded as the best example of the square-groove generation right as that generation ended.

Its cult angle is narrow but real and well-documented: multiple contemporary reviews (Orlando Golf Blogger, Into the Grain, thehackersparadise, PGA.com) independently frame it as 'the last and best' square-groove wedge, and golfers specifically sought it out in 2010 to lock in maximum-legal spin before the rule change made subsequent square-groove wedges illegal for competition — a genuine, sourced pocket of demand distinct from an ordinary annual product refresh, even though it never became a widely-discussed forum cult item beyond that specific groove-rule window.

Better players and dedicated short-game golfers, especially those who value spin consistency across lies via the debris-channeling grooves and laser-milled face texture. As with the CG14, its square grooves are non-conforming for sanctioned tournament play post-2010, so a competitive golfer needs a current conforming wedge instead; this is a casual-round and practice-green club today, prized for feel and history rather than legality.

• Marketed and reviewed at the time as the last Cleveland wedge with square/U-shaped grooves before the USGA/R&A's new groove rule took effect January 1, 2011.
• Adds laser-milled face texture — four calibrated lines between each Zip Groove, cut to the exact conforming roughness limit — on top of the CG14's groove design.
• Introduced the 'S' sole: a constant sole width from heel to toe (achieved by adding material near the heel and removing it at the toe) to improve bunker performance without hurting versatility.
• Offered a choice of the standard S-sole or a lower-bounce DSG grind, in Black Pearl, Satin Chrome or Oil Quench finishes.
• Reviewers noted it was gentler on golf balls than contemporaries, letting a single ball survive significantly more holes without heavy cover damage.

Released in 2010 as the final Cleveland wedge under the outgoing square-groove rules, directly ahead of the January 1, 2011 USGA/R&A groove-configuration change that all manufacturers had to comply with. It sits at the end of the CG14 lineage and just ahead of the rule-compliant CG15 successor generation; a modern equivalent in role is Cleveland's current RTX ZipCore wedge, built to the newer conforming groove standard.

Holds slightly better value than the CG14 due to its 'last square grooves' status and continued reputation for spin: single wedges typically sell privately for roughly $40-75 in 2026 depending on grind and condition, consistent with the catalog's higher 'A' used-price band relative to the CG14's bargain-bin 'E' band.
