About IRON C03TC
C03TC forged irons feature a classic design and advanced technology, using 3D CAD for an optimized center of gravity. Handcrafted precision forging delivers a soft feel and high performance.

3D CAD engineering optimizes the center of gravity for each iron individually
Using advanced 3D CAD design, the C03TC optimizes CG placement in every club—providing sweet spot alignment, set balance, and added forgiveness in the long iron.

Precision-integrated soft iron forging combined with CNC undercutting is used for clubs numbered 4 through 7
Ultra-precise soft iron forging combined with CNC machining ensures minimal deviations
and exceptional shape uniformity, setting a new standard for consistency across the set.

Irons were redesigned based on feedback from U.S. professional golf tours
Shaped by U.S. Tour feedback, the C03TC achieves advanced stability, trajectory versatility, and set-wide performance—easy launch in the long irons, controlled stopping power in the short.
