On each CG14™ wedge, the grooves are milled to maximum conforming dimensions using a proprietary CNC mill bit to create envelope-stretching geometry.

• Introducing ZIP Grooves™ from Cleveland® Golf—the latest envelope-stretching technology from the #1 wedge in golf. This breakthrough technology for the CG14™ 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.  
  CG14™ SPIN CONTROL  
• The milling technology of Zip Grooves creates a larger groove volume, which channels more debris at impact than traditional grooves. Consistent spin is generated from all lies due to improved contact - making Zip Grooves perfect for players that expect optimal spin and distance control.
