J1 Polestar
Double Fish J1 Polestar is a hybrid offensive blade built for players who want a balanced mix of speed, control, and spin. Its construction layers Koto wood with blue aromatic carbon fiber, Ayous, and a Tung or Paulownia core, delivering a crisp feel and explosive power ideal for aggressive loops and drives. Positioned as an accessible option, it helps intermediate players elevate their attacking game without demanding an extreme skill level.
This 5W2C (5 Wood, 2 Carbon) construction is a popular hybrid design known for speed and stiffness. Outer Koto layers provide a crisp feel and good spin potential, while blue aromatic carbon fiber enhances the sweet spot and power. Ayous and the central core wood balance feel and flexibility.

✦Our expert analysis of this blade's performance characteristics
Designed as an OFF+ blade, J1 Polestar delivers significant speed potential from its Koto outer plies and blue aromatic carbon layers. This combination generates good explosive power, particularly effective on serves and first attacks, making it suitable for powerful drives and fast offensive play.
Despite its high speed, J1 Polestar maintains commendable control. The hybrid construction, especially the wood core and transition layers, helps dampen vibrations and provides a transparent feel, allowing for precise placement during rallies. Many players find it easy to control, even at intermediate levels.
Players report a transparent and crisp feel that offers direct feedback from the ball. It's not overly soft, which contributes to its speed, but the wood core provides enough cushioning to prevent an excessively stiff sensation, often drawing comparisons to blades like the Viscaria.
Our testing shows it's easier to create arcs with this blade, and its characteristics suit loop-driven play, indicating a medium to medium-high throw angle that aids in aggressive topspin rallies.
Carbon layers lead to a faster ball exit, so dwell time isn't exceptionally long. However, the wood plies and specific construction provide sufficient ball contact for effective spin generation, especially when paired with suitable rubbers.
Inclusion of carbon fiber places J1 Polestar on the stiffer side, contributing to its speed and direct feel. It offers moderate flexibility—enough for spin generation but primarily geared toward delivering direct power.
The blade strikes a good balance in vibration feedback. While carbon increases stiffness and speed, the wood construction filters out excessive harshness, delivering a clear and comfortable feel on impact.
J1 Polestar features solid construction and quality materials considering its price point. The use of Koto and aromatic carbon fiber indicates a manufacturing focus on delivering performance characteristics that rival higher-end blades, offering good value without compromising on build.
Technology
Double Fish J1 Polestar uses a 5-ply wood and 2-ply carbon fiber (5W2C) hybrid construction. This design leverages both materials: outer Koto wood plies are known for hardness and spin imparted, while blue aromatic carbon fiber layers expand the sweet spot, increase stiffness, and boost overall speed. Internal wood layers (Ayous and a central Tung or Paulownia core) add cushioning and feel, balancing the carbon's stiffness. The result is a blade with good power, a crisp feel, and a clear impact sound, tailored for modern offensive table tennis.
Similar Blades
Butterfly Viscaria
J1 Polestar is frequently compared to Butterfly Viscaria due to similar construction with outer Koto, aromatic carbon fiber, Ayous, and a wood core. TTSensei experts note it offers a comparable feel and performance at a lower price, feeling like Viscaria but more solid, with a similar arc treatment on the handle front.
Butterfly Lin Gaoyuan ALC / Butterfly Fan Zhendong ALC
These blades share the same external blue aromatic carbon structure as J1 Polestar. While J1 Polestar may not match their overall power storage ability, it delivers similar playing characteristics that are easier to control and adapt to for intermediate players seeking a high-end feel.
