Henrys' Numbers club represents a major technological advancement in juggling prop design. By replacing the traditional ash wood core with a carbon fiber tube , Henrys reduces the total mass to 160 grams , approximately 25 to 30% less than a standard professional club. This weight reduction lowers the energy required for each throw and delays the onset of muscle fatigue.

• Carbon Core: Offers superior rigidity and consistent flex. The carbon pole is protected by a special foam sleeve and a protective film to increase its structural stability.
• "Tiny Knob" System: New hand-polished EVA tip with a reduced profile. This compact design makes it easier to hold 4 or 5 clubs in one hand when starting with 7 or 9 targets.
• "Loop Slim" handle: A thinner handle profile (molded in one piece from polyethylene) that improves palm grip during multiple manipulations.

The use of carbon fiber and a lightweight translucent body (77g) alters the apparatus's haptic response. This weight reduction is a key factor in the physical longevity of artists training several hours daily, significantly limiting the risk of tendonitis in the elbow and wrist.

Acoustic note: The carbon structure produces a more muted sound upon impact, different from the sharp clatter of wood-core models.

Details on Use and Maintenance

Carbon is a high-performance composite material that requires a strict usage protocol:

• Wind sensitivity: Due to its low weight (160g), this club is intended exclusively for indoor use. The slightest breeze affects its trajectory.
• Tactile Feedback: The extreme lightness requires a recalibration phase of a few days to get used to the absence of the usual inertia.
• Maintenance: Unlike wood, a carbon core subjected to a critical shock (crushing) cannot be repaired and requires replacement of the rod.
