A 5+2 ply blade was developed based on CCF technology (Closing Core Fibre), which means that the carbon fibre is placed directly above the wood core, a result that effectively increases the speed and control of the blade as a whole. The addition of lightweight and soft synthetic fibres produced in the UK enables the blade to have excellent stability while ensuring excellent performance output. This is an offensive blade with superior comprehensive performance.

The walnut upgrade is inspired by the walnut 5 used by the Olympic champion Xu Xin. This blade with an excellent feel has become one of the classic blades. Similarly, Walnut upgrade uses the same surface material as Walnut 5 (extremely strong pure wood)—walnut, which not only retains the iconic characteristics of the classic blade but also brings new life to the modified blade with the introduction of new synthetic fibres!
