Sounds like weight savings....
The DRT wedges are co-forged forged from soft 1025 carbon steel and CMC (Ceramic Matrix Composite) for an incredibly soft and feel and optimal center of gravity locations not typically found in wedge designs. The CMC is a very light material that when positioned correctly helps to move mass towards the center of the club face and greatly eliminates typical design shape restrictions due to excessive weight to allow for wider range of sole widths without sacrificing the clean, player preferred, traditional wedge aesthetics.
Co-Forged CMC
Features:
True Forged from 1025 carbon steel using advanced multi-step forging process, providing unparalleled feel and consistency.
Utilizes CMC (Ceramic Matrix Composite) strategically placed internally to achieve Optimal Mass Placement (OMP), greatly enhancing feel and optimizing trajectory control.
