Diamana™ Thump™ Irons

A longtime staple in the Japanese premium golf market, Diamana Thump expands Diamana’s legendary wood-shaft DNA into the iron category. Designed as a neutral foundation for the golf swing, Thump complements rather than overrides player delivery — producing consistent impact, stable flight, and trusted feedback.

Constructed using premium multi-material composite engineering, Thump utilizes advanced carbon fiber materials and reinforced structural sections to precisely control torque, feel, and bend profile. The result is a shaft that remains exceptionally stable through transition and impact while maintaining Diamana’s signature smooth response.

Positioned between the iconic Diamana Blue and White feel profiles, Thump features a mid-high kick point paired with excellent vibration damping properties. Players experience solid, confident feedback without the harshness commonly associated with traditional steel iron shafts.

Reinforced anti-ovaling construction allows golfers to maintain clear awareness of clubhead position throughout the swing, promoting improved center-face contact and reliable stopping power on approach shots.

• Current Diamana wood users seeking a seamless transition throughout the bag
