About this blade
Butterfly Fan Zhendong CNF is a 7-ply blade built around CNF fibre placed outer, with Koto on the playing surface and a Kiri core. Koto in the outer layer: Hard, dense outer veneer — a crisp, direct hit and plenty of speed straight off the bounce. Ayous in the medial layer: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. Kiri in the core: Paulownia core — extremely light, damping the stack and slowing the blade down for control. CNF in the fibre layer: Cellulose nanofibre — a soft, damping reinforcement with a very wooden, quiet impact. Physically it measures 5.7 mm thick, around 89 g. Butterfly positions it for off+ play.
TTDNA ratings
NormalizedPerformance
Construction
Material properties
Playing profile
A TTDNA blade rating measures how much of the named characteristic a blade has. For descriptive rows — flex, stiffness, vibration, head heaviness, weight, thickness, carbon feel, softness, technique requirement, spin sensitivity — a higher number means more, not better.
TTDNA ratings are normalized comparison values, not laboratory measurements. They are built from published specifications, technical sources and structured product evidence, converted to one 0–100 scale. Where a directly comparable measurement is unavailable, the value is an evidence-based estimate. Overall-style scores are composites of several characteristics. Methodology
