The Nittaku Acoustic Carbon is based on the original Acoustic blade, with the addition of two carbon layers to give it the characteristic feel of a carbon blade. This version features a larger handle, making the blade heavier and slightly faster than the standard Nittaku Acoustic Carbon. It is ideal for players who find the original handle too thin. Made in Japan, Nittaku has updated the lens design, but the blade itself remains unchanged. Once the old lens design is sold out, the new version will be sent.
