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.

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.
