Nittaku Super DO Knuckle

Nittaku Super DO Knuckle – Medium Pips Rubber with Exceptional Disruptive Effect
Nittaku Super DO Knuckle is a Japanese-made medium pips-out table tennis rubber, known for its exceptional wobble effect and versatile offensive capabilities. Developed with innovative sponge technology, Super DO Knuckle features a medium-hard sponge (~42.5° JPN, ~49–52° ESN) and larger pips than DO Knuckle, ensuring maximum disruption while maintaining speed. Ideal for close-to-table players combining attack and defense (ALL/OFF-). Approved by ITTF and JTTA, the rubber includes a sticky protective film for easy gluing and comes at an affordable price.

Nittaku Super DO Knuckle combines characteristics of both short and long pips:

• Sponge (Medium-Hard): Fine-pored, medium-hard sponge (~42.5° JPN, ~49–52° ESN), harder than Flyatt Soft (~30° JPN) but similar to Fastarc S-1 (~44°). Offers moderate catapult effect for offensive speed while maintaining control during blocks. Sponge thickness: OX (no sponge, for DEF/ALL) and 1.4 mm (ALL+/OFF-). The OX version is slower and more controllable, while the 1.4 mm version is faster, suitable for attacking. Compared to DO Knuckle, Super DO Knuckle features horizontally aligned pips, increasing both disruption and control.

• Top Sheet: Grippy top sheet with larger, stiffer, medium-long pips (larger grain than DO Knuckle), designed for maximum wobble effect. The horizontally aligned pips (unlike the vertical pips in DO Knuckle) make control easier while maintaining strong spin reversal. Grip is stronger than Moristo SP but weaker than tacky inverted rubbers (e.g., Fastarc G-1). The rubber is minimally sensitive to opponent's spin, making it easy to block topspins and return knuckle balls.
  Durability: ~100–150 hours with care.

• Technology: New rubber composition and pip structure deliver a strong wobble effect, especially during blocks and counterattacks. The horizontal pips improve control and spin variation compared to DO Knuckle’s vertical, spin-oriented pips.

• Throw Angle: Low to medium, ideal for blocks, counterattacks, and short strokes near the table. The throw is higher than Wallest One (OX) (low throw) but lower than Fastarc S-1 (medium-high throw). Perfect for fast, disruptive close-to-table play.

• Spin Sensitivity: Low spin sensitivity due to stiff pips and sponge, allowing easy conversion from topspin to backspin and effective knuckle ball returns. Ideal for players struggling against strong topspin strokes.

Weight: ~35–40 g (cut, 1.4 mm), lighter than Fastarc G-1 (~49 g), heavier than Wallest One (OX) (~20–25 g). Available in red and black, compliant with ITTF regulations. The sticky film eases gluing—water-based glue is recommended.

Nittaku Super DO Knuckle Technical Specs:

• Speed: 7.75/20 (~7.5/10, ALL+/OFF-). Medium-high speed, suitable for counterattacks and close-range hits. Faster than DO Knuckle (7.5/20) or Wallest (5.75/20), but slower than Moristo SP (~8.5/10). Other sources rate it 73/100 (~7.3/10).

• Spin: 5.75/15 (~6.5/10). Medium spin with strong wobble effect, effective in blocks and short strokes. Lower than DO Knuckle (6.0/15) or Feint Long II (~8.0/15), but stronger than Wallest One (5.75/15). Some sources: 59/100 (~5.9/10).

• Control: 90/120 (~8.5/10). High control, especially in blocking, counterattacks, and service returns. Higher than DO Knuckle (~8.0/10), but slightly below Wallest One (7.5/10). Other sources: 8.8/10.

• Sponge Hardness: ~42.5° JPN (~49–52° ESN, medium-hard).

• Trajectory: Low to medium arc—ideal for blocks and counterattacks near the table.

User feedback highlights: excellent wobble effect, control, and versatility, though topspin strokes require solid technique.

Comparison with Similar Rubbers:

• Nittaku DO Knuckle: Speed (7.5/20), Spin (6.0/15), Control (~8.0/10). Slower, spinnier, vertical pips, less disruptive. Suitable for ALL/DEF+.

• Nittaku Wallest: Speed (5.75/20), Spin (5.75/15), Control (8.0/10). Slower, more controllable, designed for DEF players—less suitable for offense.

• Butterfly Feint Long II: Speed (~6.5/20), Spin (~8.0/15), Control (~7.5/10). Spinnier but slower, best for DEF+/OFF-.

• TSP Curl P-1R: Speed (~6.0/20), Spin (~8.0/15), Control (~7.0/10). Spinnier, less control, suitable for DEF.

Super DO Knuckle stands out for its maximum disruptive effect and offensive potential, perfect for close-to-table play.

Blade Compatibility:

Pairs well with all-round and offensive blades:

• Nittaku Latika: Controlled, suitable for ALL+.

• Yasaka Sweden Extra: All-wood, great control, good for ALL+/OFF-.

• Nittaku Goriki: Defensive, enhances control, suitable for DEF+/ALL+.

• Butterfly Korbel: Stability, OFF-.

• Nittaku Acoustic: Control + speed, suited for ALL+/OFF-.

Wood blades boost control, while carbon blades (e.g., Nittaku Flyatt Carbon) increase speed. Suitable for backhand, especially for blocks and counters.

Target Audience:

Nittaku Super DO Knuckle is designed for players seeking disruption and attack:

• All-round and offensive players (ALL+, OFF-) who play close to the table.

• Disruptive play: Highly effective in blocks, counters, and flicks.

• Blocking: High control, strong wobble effect to confuse opponents.

• Counterattacking: Speed and pip design support smashes and drives.

• Service return: Low spin sensitivity, easy return of spinny serves.

• Topspin: Limited but possible with 1.4 mm sponge—requires proper technique.
