Though golf club technology has made giant leaps through the course of history, changes in the actual materials used by the manufacturers have been few and far between. Cleveland Golf began producing golf clubs from a revolutionary material in 2004 when they came out with the CG10 wedges. These wedges were, and still are, widely hailed as the best feeling wedges in golf. (See "Editor's Choice" Golf Digest, Feb. 2005)

The last time there was a change this significant, they started making woods out of metal.

CG10™ WEDGES >> THE METAL:
Our goal was to find or create a material that would damp vibration in an unprecedented fashion and could be readily manipulated and engineered for performance. In fall of 2003 we created the first wedges made from light density steel. Since then we have added Black Pearl™ wedges as well as the CG1's, CG2's and the new CG4's to Cleveland Golf’s line of CMM brand clubs.

This new metal, while not a composite, is infused with 17 times more carbon than traditional 8620 and 1020 steels. Using a process unique to the CMM material, microscopic carbon spheres are infused within the molecular structure of the metal. This creates a matrix that is 10% less dense than ordinary steel yet it maintains the hardness and manipulation properties of cast or forged carbon steel. These density relieving spheres within the CMM metal also dramatically damp vibration offering a pure, soft feel never before achieved in any golf club. Needless to say, Cleveland Golf has a patent pending for golf clubs made of this breakthrough material.

CG10™ WEDGES >> THE PERFORMANCE:
The CG10 wedge has been widely hailed as the best feeling wedge Cleveland Golf has ever built. And that’s saying something. The feel is unmistakable. In blind tests on tours worldwide, the CG10 wedge was overwhelmingly preferred for its soft, pure feel and was easily distinguished from other wedges. Even the sound at impact is sufficiently different from other wedges, adding to the distinct feel of the CMM metal. Extensive player and robot testing has shown that, while the CG10 wedge produced similar spin to other Cleveland wedges with soft cover tour balls, it dramatically increased spin on hard cover distance balls. This translates into consistency for the low-handicapped player, and added performance for those seeking spin from a distance ball.

CG10™ WEDGES >> THE DESIGN:
With its light density properties, CMM metal affords Cleveland Golf club designers an unprecedented degree of design freedom. This freedom enabled the Cleveland design team to create a wedge that, while classic in appearance, has subtle design refinements that add to the unprecedented performance of the CG10 wedge. Although overall head weights are comparable to past Cleveland wedge series, the CG10 wedge features more weight positioned within critical areas to improve feel and performance without sacrificing traditional shape. Weight has also been moved to high stress areas, further improving feel, even on miss-hits.

Ultimately, more mass has been placed directly behind the impact area and lower in the head thus giving the CG10 wedge a solid, "muscle-back" appearance.

What's the one thing that all golfers agree on? Glare hurts.

Nobody wants to be blinded by the sun as it's reflected off their wedge. To combat this, Cleveland Golf has developed an advanced surface coating process that drastically reduces blinding glare while helping the club maintain its soft feel, bendability and resistance to rust.

CG10™ BLACK PEARL™ WEDGES >> MULTI-LAYERED MICRO-COATING TECHNOLOGY:
Black Pearl wedges feature a proprietary micro-coating that’s formed using an advanced, multi-stage process. It starts with a hand-ground and polished CMM™ CG10 clubhead. Next, using a precise electroplating process, two layers of soft nickel (Ni) are deposited onto the surface. The clubhead is then inspected and polished to a glare-reducing satin finish. The second primary layer is electrically deposited as a thin, yet durable layer of chromium (Cr).

This provides a corrosion-resistant layer to the club while highlighting the satin finish. The final step to this techno-logically advanced finish is a tertiary outer coating. Through an advanced coating process, microscopic particles of a proprietary compound are first vaporized and then condensed onto the clubhead. The end result of this time-intensive process is a rich, glare-reducing finish with enhanced corrosion resistance and a softer feel when compared to other dark metal finishes.
