The CG12™ combines classic wedge design with advanced manufacturing processes. On each CG12™ wedge, the grooves are milled to maximum conforming dimensions using a proprietary CNC mill bit to create envelope-stretching geometry. To improve shot consistency, the new groove geometry was coupled with an innovative plating process - making ZIP Grooves™ Cleveland® Golf's most consistent, precise, and visible wedge technology to date. 

• 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™ 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.
