The CG12™ DSG combines Zip Grooves™ with state-of-the-art technology and versatility offered by Dynamic Sole Grind (DSG). When opening the face at address, this Dynamic Sole Grind allows the leading edge of the CG12™DSG to remain closer to the ground than the original CG12. Throw in the deepest grooves in golf and you get a wedge that allows for high, soft flop shots with zip. 

• Introducing ZIP Grooves™ from Cleveland® Golf—the latest envelope-stretching technology from the #1 wedge in golf. This breakthrough technology for the CG12™ wedge features consistent milling of each groove to maximum conforming dimensions. The absolute integrity of these grooves is maintained by the application of a proprietary coating to each groove for protection during the face sandblasting process.
• CG12™ DSG SPIN CONTROL   
  The technology of Zip Grooves creates a larger groove volume which channels more debris than traditional grooves to improve contact with the ball. This milling optimizes spin on each and every shot - making Zip Grooves perfect for players that expect optimal spin and distance control.
