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.

Note: The plain Innerforce Layer ALC veneer list must not be carried over: ALC.S uses a different core build, and its outer veneer has not been identified.
About this blade
Butterfly Innerforce Layer ALC.S is a 7-ply blade built around ALC fibre placed inner and a Ayous core. Spruce in the medial layer: Stiff, resonant core wood — fast energy return with a clear, high-pitched feedback. Ayous in the core: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. ALC in the fibre layer: Arylate-carbon — stiffens the stack and enlarges the sweet spot while keeping a wooden feel. Physically it measures 5.5 mm thick, around 88 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
