Its most significant feature is the use of "3K twill weave carbon" and the "autoclave molding process," commonly used in racing car bodies, to create shafts specifically designed for golfers based on their skill level, physique, and objectives. The autoclave molding process, performed in a large high-pressure vessel, allows for the creation of shafts with a smooth surface, enabling precise manufacturing as designed. According to the company, the use of "3K twill weave carbon" prevents the shaft from collapsing at its maximum flex during a swing, thereby increasing the shaft's stored energy and efficiently transferring it to the ball at impact. This results in "distance" and "accuracy" that set it apart from conventional shafts. They have succeeded in developing a shaft that can be used by golfers from beginner to advanced levels. The "type F1" is designed for golfers who are hitting a wall around 220-230 yards, offering a distance increase of 20-30 yards and excellent fairway keeping ability. It is also recommended for advanced golfers who hit over 260 yards and desire a more "hooking" feel.
