The thickness of the clubface has been optimized by using a supercomputer to achieve both lighter weight and a larger repulsion area. We chose from over 30,000 calculated shape designs, selecting those that offer the best performance for maximizing the repulsion area. The resulting UD+2 Ultimate Face delivers an enlarged repulsion area to minimize the loss of flight distance from off-center hits. Additionally, we achieve the ultimate face through precision crafting in a process called "milling and press molding."

Optimally placing 40 grams of weight—35 grams of fully integrated weight in the sole (which takes up some 20% of the head weight) and 5 grams of badge-shaped weight—creates the dual benefits of an extremely low CG height and a deep CG. This ultra-low deep CG allows flight with high trajectory and low spin. Additionally, the large 34° CG angle allows the face to bounce back easily and improves the sweet spot.

Since the super-low CG design delivers a high launch angle, the repulsion efficiency and kick velocity are also high, which translate into strong loft. Furthermore, this strong loft allows a low CG for the face, which prevents energy loss and minimizes loss of flight distance, even if contact is made with the lower part of the face.

The Fairway Wood (#3) uses a precision cast titanium body that is fully integrated with the face. Eliminating welding between the body and face increases the deflection area and achieves greater repulsive force. Additionally, the Utilities and other Fairway Woods, besides the #3, use a maraging steel cupface of uneven thickness, which allows deflection across the face, enlarges the repulsion area, and increases repulsion performance.

The Fairway Wood #3 utilizes a 118-gram full tungsten alloy sole. Additional weight across the entire sole achieves a super-low CG, in addition to a super-deep CG. Furthermore, the Utilities and other Fairway Woods, besides the #3, use inner weights in a sole that is thicker overall, which achieves a low CG height and a deep CG.

The series uses original shafts jointly developed with Mitsubishi Rayon. The tip is designed with less stiffness and more softness for better contact and a shaft that flexes well. The torque is greater, and you can hit with a swing path that is automatically stabilized.

We designed the Iron to have a low and deep CG by using a "blade undercut" structure that makes the top blade lighter and moves the surplus weight to the back of the sole. Additionally, the head shape is shorter than previous models for further evolution in lowering the CG, which allows higher loft. This new head structure brings the strike point closer to the CG and boosts flight efficiency. Furthermore, we have been able to use the FRICOFF sole, which trims the width of the sole 2.1 mm narrower than previous models and shaves the rear portion of the sole. The result is improved drive-through.

Achieving high trajectory from the super-low and deep CG design delivers strong loft with repulsion efficiency and high kick velocity. Additionally, a lower CG in the face prevents energy loss. Even if you hit with the lower part of the face, the close CG minimizes the loss of flight distance.

The key features of the putter are a solid hitting sensation and a great impact sound from the non-insert face, which delivers nuanced feedback. The non-balanced face design is optimal for golfers with a natural-feeling "in to in" swing. Additionally, the center section of the three-surface sole makes contact with the ground for stability at address every time, which achieves extreme faithfulness.
