Cleveland CG10 Low Bounce wedge. Made from a proprietary material called- Carbon Metal Matrix, or CMM. This new material is infused with 17 times more carbon than traditional 8620 and 1020 carbon steels. Using a process unique to CMM, the carbon is infused into microscopic spheres suspended within the molecular structure - creating a matrix that is 10% less dense and 15% softer than traditional carbon steel. These density relieving spheres within CMM dramatically damp vibration, offering a pure, soft feel The Low Bounce Wedge is an outs choice for shots from tight lies and conditions. The combination of less and narrower sole width lowers the edge of the blade to promote clean every shot. Perfect for players who creative around the greens and in the sand and who have shallow attack angle impact. Less bounce and narrower make it easier to open the face and soft landing flop shots.
