About this blade
Butterfly Korbel SK7 is a 7-ply blade built around an all-wood stack, with Limba on the playing surface and a Ayous core. Limba in the outer layer: Soft, open-grained outer veneer — long dwell, a wooden feel and easy spin on slow strokes. Ayous in the medial layer: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. Ayous in the core: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. Physically it measures 6.8 mm thick, around 92 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
