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.

Hard, dense outer veneer — a crisp, direct hit and plenty of speed straight off the bounce.

Pure zylon fibre — light reinforcement that keeps flex and feel while widening the sweet spot.

Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.

Paulownia core — extremely light, damping the stack and slowing the blade down for control.

About this blade
Butterfly Timo Boll ZLF is a 7-ply blade built around ZLF 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. ZLF in the fibre layer: Pure zylon fibre — light reinforcement that keeps flex and feel while widening the sweet spot. Physically it measures 5.4 mm thick, around 82 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
