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.

Stack order — face A to face B

01

Hard, dense outer veneer — a crisp, direct hit and plenty of speed straight off the bounce.
02

Arylate-carbon — stiffens the stack and enlarges the sweet spot while keeping a wooden feel.
03

Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.
04
Kiri — coreCore
Paulownia core — extremely light, damping the stack and slowing the blade down for control.

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.
