Blade Review No. 10: Reactor Yu Jian — An Accessible Budget Outer Carbon Blade

Test rubbers:

• Forehand: DNA Dragon, Blue Sponge Cuifeng high-hardness
• Backhand: Gaibo Power 37-degree, Spell M

Introduction

1. Many people still associate the Reactor brand mainly with the Fire Qilin rubber, but since 2024, Reactor signed national team player Chen Qi, launched the Gaibo Power rubber series, and rolled out the Yu Jian, Po Chen, and Weimu blade lines — putting the brand back in the spotlight.
2. Today we’re focusing on their most popular model: the Yu Jian blade.

First Impressions

1. The semi-transparent box with a gradient blue finish gives it a simple, clean look.
2. “Yu Jian” is printed on the face with a martial arts aesthetic — the overall interlocking wood grain design looks clean and attractive.
3. The surface feels very smooth with an even protective coating applied, and the handle is clearly sanded down — it doesn’t feel rough in hand. Comparing the build quality to the Jiji 7, the Yu Jian feels genuinely well made.

Performance

1. Feel: Fairly soft and springy — not stiff when hitting, more of a soft, controllable sensation. Although it’s an outer carbon blade, ball dwell is moderate and the feel resembles an all-wood blade. It needs to be paired with rubbers of at least moderate bounce to ensure the ball clears the net. It encourages players to take the ball actively and commit to their swing. Feel: 6.5 out of 10.
2. Arc: Average, 6.5 out of 10. Looping is stable, landing mid-trajectory.
3. Spin: Average, 6.5 out of 10. Decent spin output, landing mid-range.
4. Power: Not a strong point — this is common across 100-yuan-range blades. The depth only really holds up at close range; stepping back you’ll feel the power running out. That said, what makes the Yu Jian different is: although the power isn’t big, it doesn’t feel hollow — it’s fairly easy to drive through, and the blade has good resilience once you engage it. Score: 6 out of 10.
5. Speed: Decent departure, but not fast. Speed is comparable to an all-wood or traditional inner carbon blade (like the Jiji 7 or Competitor Power), slightly slower than an offensive inner carbon (like the 301X or Liang Jingkun ADC). Score: 6 out of 10.
6. Extra notes: Great for flicks and close-range attacks — once driven through, the blade is crisp but not overly lively, so the arc stays stable. You can commit to your swing with confidence.

Recommendation

1. All the scores above are 6–6.5, sitting between pass and good — but that’s a vertical comparison against all blades. In a horizontal comparison against blades in the same price range, the Yu Jian easily earns 8 or above.
2. Why an 8-plus? Because it’s priced at just around 100 yuan yet handles everything reasonably well, and the build quality is genuinely impressive at this price.
3. Final verdict: The Yu Jian is a close-to-mid-range loop-and-attack blade designed for beginners and developing players. It has a low barrier to entry, making it ideal for beginners to practice and improve — building feel, correcting technique. It’s a genuinely accessible entry-level outer carbon blade.
