Dawei Bio X50 blade was released in 2007. This new product line features higher quality wood plies and greater craftsmanship.
The Dawei Bio X50 Uniaxial Carbon blade has crystal-coated outer plies and ayous/uniaxial carbon inner plies. It is very similar in look to the Butterfly Kreanga Carbon, except for the fact that the grain is still shown to comply with current ITTF laws. This Blade is rated as OFF, and I would say that it plays very much like an OFF-. This blades is mildly flexible, which adds extra speed when hitting through the ball. This blade has ample control.
Dawei have even lengthened the handle, it is now 100mm long, which is the standard amongst most blades.
