World’s first* integrated forging with a ceramic core
By forging ceramic seamlessly inside the head, the C01TB ic achieves a precise center of gravity and advanced stability—pushing blade design beyond conventional limits.
Center of gravity designed specifically for every iron
A new 3D CAD center of gravity design enhances set balance, sweet spot alignment, and shot control—combining classic blade sharpness with modern forgiveness.
Iron features were further redefined using feedback from U.S.Tours
Shaped by U.S. Tour feedback, the C01TB ic achieves advanced stability, trajectory
versatility, and set-wide performance—easy launch in the long irons, controlled stopping
power in the short.
TECHNOLOGY - Crafted with evolved ceramic integrated forging
Structure
Ceramic with light specific gravity is built into the S20C soft iron forged head.
Designed with a larger face size and peripheral weight distribution for a muscleback.
This creates forgiveness that is comparable with cavity backs.
The shape and thickness determine performance
C01 TB inner CERAMIC IRON
Production method
Forged together in one piece with S20C soft iron round bar with built-in ceramic.
The ceramic is precisely arranged in the position as designed from the center of the head to the heel.
It is made of a single material, soft iron, and has an attractive feel. However, the performance is not much different from musclebacks of the past.
Features
By building in ceramic which is far lighter in specific gravity than metal into the head, the C01TB ic provides cavity back-like forgiveness despite being a muscleback iron.
The center of gravity is designed by 3D CAD, making the ceramic exquisitely positioned from the center to the heel. Provides stable clubhead movement when swung and control performance required of a muscleback at the same time, achieving a "forgiving but flexibly bendable" maneuverability.
