The Goriki Drive blade features a 6-ply wood construction, offering an excellent balance for executing offensive attacks. The outer plies are crafted from brown walnut wood, while the core is made of hinoki cypress. This rigid build provides ample power to break through your opponent's defense. The Goriki series, also known as the Rigidity series, was developed by Dr. Rokuro Sakuma, Nittaku's equipment advisor, who has supplied unique equipment to many Japanese national team players. Blade size: 160×154mm. Made in Japan.
