Nittaku has released a special limited edition of the Kasumi Eternity blade to honor Kasumi Ishikawa's birthday. With only 700 pieces produced, and just 200 available internationally, this blade is highly sought after by collectors. Kasumi contributed to the design and artwork, with an image of her playing and her name inscribed in Japanese Kanji on the blade. Built with a veneer structure similar to the Acoustic Carbon Inner, this version includes a slightly thicker core, providing increased speed and stiffness compared to the standard Nittaku Carbon Inner. Made in Japan.
