BY1091 Even
Sanwei BY1091 Even is a high-performance offensive blade engineered for the modern 40+ plastic ball. Its defining feature is a complex 19-layer composite of 10 wood plies and 9 soft carbon layers, creating a unique dual character. It feels hard for explosive speed on powerful attacks yet soft for enhanced dwell time and spin generation on close-to-table strokes. This design produces swift, violent ball bounces, making it a formidable weapon for players who want to dominate rallies with aggressive speed and heavy spin.
The blade uses a highly complex 19-ply construction with an alternating pattern of wood and soft carbon fiber layers. While the exact wood species are not fully detailed, sources suggest a structure that begins and ends with soft carbon. This dense, sandwich-like design is engineered to provide a unique blend of stiffness for power and softness for dwell time and control.
TT Sensei Ratings
✦Our expert analysis of this blade's performance characteristics
Sanwei BY1091 Even is a very fast blade, consistently rated highly for offensive play. Our testing shows its 19-layer construction delivers hard characteristics that produce a rapid ball departure speed, especially during powerful attacks and loops. This makes it an excellent choice for aggressive players looking to overwhelm opponents with sheer pace from mid-distance and beyond.
Despite its high speed, the BY1091 Even maintains excellent control, a rare and valuable combination. This is largely attributed to its soft carbon layers, which create more time for ball compression. This extra dwell allows for better spin generation and precise placement during close-to-table exchanges, giving skilled players a high degree of touch and accuracy.
The BY1091 Even offers a medium feel that is notably dampened. The multiple soft carbon layers absorb much of the vibration, resulting in a solid impact with minimal feedback through the handle. This creates a controlled, less lively sensation compared to all-wood blades, which many players appreciate for its stability.
It produces a medium-high throw angle, ideal for aggressive topspin play. The combination of speed, dwell, and the blade's character creates a pronounced arc on loops, allowing players to generate deep, penetrating shots that challenge opponents.
Dwell time is a strong point for this blade. The soft carbon layers enhance ball compression, allowing for a longer contact period. This is crucial for generating heavy topspin and provides a forgiving quality on brush-looping strokes, even at high speeds.
The blade exhibits a medium level of flexibility. It balances a certain inherent stiffness from its multi-layer construction with enough give to aid in spin generation. This results in a responsive feel that supports both powerful drives and nuanced, spin-oriented shots.
Vibration in the handle is surprisingly low to medium. Players report a very dampened sensation, with little to no distracting feedback on impact. This contributes significantly to the blade's controlled and solid feel, making it comfortable for extended play.
TTSensei experts note the BY1091 Even is praised for its excellent design and build quality, particularly given its price point. The intricate 19-layer construction is a testament to advanced manufacturing, resulting in a well-balanced and consistent blade. Players find it provides reliable, tournament-ready performance that feels solid and well-made in hand.
Technology
The core technology of the Sanwei BY1091 Even is its advanced '10+9 soft carbon' composite construction. This involves precisely layering ten wooden plies with nine layers of soft carbon fiber in an alternating pattern. This intricate design aims to synthesize two opposing characteristics: the hard, direct speed of carbon and the softer, dwell-friendly feel of wood. Engineered for the 40+ plastic ball, this technology seeks to provide explosive power for winners while retaining the touch and spin necessary for controlled, modern rally play.
Similar Blades
Yasaka Dynamix 17
The Yasaka Dynamix 17 is a notable alternative, often compared for its similar high-ply count (17 layers). A key difference is that the Dynamix 17 is an all-wood construction, whereas the BY1091 integrates soft carbon. This comparison highlights how the BY1091 aims to achieve the benefits of a complex multi-ply design but with the added speed and dampened feel characteristic of carbon fiber.
