One blade, drawn as technical linework at real shakehand proportions. The laminated edge along the crown and right rim exposes every ply boundary in the stack. Edge depth is illustrative because physical veneer thickness is not published.

About this blade
Butterfly Defence II is a 3-ply blade built around an all-wood stack, with Willow on the playing surface and a Ayous core. Willow in the outer layer: Light, springy veneer — soft catch with a lively release out of the blade. Ayous in the core: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. Butterfly positions it for def play.
TTDNA ratings

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
