Kool
Joola Kool is a 7-ply hybrid offensive blade engineered for extreme speed and direct power. Its unique construction centers on a thick balsa core, flanked by Texalium fiber layers and finished with Spruce and Limba outer plies. This design creates a lightweight yet stiff platform that delivers a powerful, rocket-like response, earning it a reputation as a specialist weapon for aggressive attackers. The blade offers a medium-high throw and a crisp, direct feel, making it ideal for advanced players who prioritize raw pace and a large sweet spot over maximum spin generation.
The blade is a symmetrical 7-ply construction. From the outer playing surface inward, it features Spruce, then Limba, a layer of Texalium fiber, a thick Balsa core, another layer of Texalium, Limba again, and finally the inner Spruce layer. This sandwich design places the unique balsa core and Texalium fibers at the heart of its performance.

✦Our expert analysis of this blade's performance characteristics
Joola Kool delivers exceptional speed, ranking among the fastest offensive blades available. The combination of a thick balsa core and stiff Texalium fiber layers creates a catapult effect that generates explosive power, particularly effective for counter-drives and powerful attacks. This high pace is designed to handle the modern 40mm ball with authority.
Control is the clear trade-off for the Kool's immense speed. While it offers decent stability for direct drives, generating heavy spin on loops requires advanced technique due to its stiffness and shorter dwell. Players find it demands precise timing and a confident stroke to keep powerful shots on the table consistently.
The feel is unique—stiff and direct with a crisp 'tock' feedback, yet the balsa core provides a subtle springiness underneath. It's not a soft feeling blade; the Texalium layers dominate the sensation, creating a hard, responsive touch that communicates impact clearly without being overly harsh.
The blade produces a medium-high to high throw angle, ideal for aggressive, attacking play. This trajectory helps lift the ball over the net with power, facilitating strong loops and offensive shots from mid-distance.
Dwell time is moderate. The balsa core contributes some holding sensation, but the overall stiffness from the Texalium limits prolonged contact. It provides enough dwell for effective looping and counter-hitting, though players seeking extreme brush-looping spin might find it slightly lacking.
This is a very stiff blade. The thick core and reinforcing Texalium fibers create a rigid platform with minimal flex. This stiffness is a key contributor to its high speed and direct power transfer, making it less forgiving than more flexible, all-wood blades.
Vibration is low to medium. The construction effectively dampens excessive shock, resulting in a clean, direct feel upon impact. Players note a distinct feedback without unwanted buzzing or harsh vibrations, contributing to a solid and connected sensation.
Joola Kool is built with quality materials and robust construction, resulting in a durable blade that holds up well to aggressive play. The finish and assembly are consistently good, with no widespread reports of construction flaws, making it a reliable piece of equipment for competitive use.
Technology
Joola Kool's technology centers on a unique hybrid layup. A thick balsa wood core is sandwiched between two layers of Texalium, a material that fuses aluminum with fiberglass for stiffness and rebound. Outer layers of Spruce and Limba wood provide the playing surface and structural stability. This design aims to merge the lightness and inherent dwell of balsa with the speed-enhancing stiffness of synthetic fibers. The result is a blade engineered for uncompromising offensive power, a large sweet spot, and a distinct, direct feel that prioritizes explosive acceleration.
Similar Blades
Butterfly Balsa Carbo X5
TTSensei experts note the Butterfly Balsa Carbo X5 is a comparable balsa-core hybrid. Players report the Kool may feel slightly slower and offer less control than the Balsa Carbo X5, positioning the Butterfly blade as a potentially more refined and controllable alternative within the same performance category.
Yasaka Sweden Extra
Many players find the Yasaka Sweden Extra to be an even faster blade when compared directly. This suggests the Joola Kool, while extremely fast, sits just below the absolute top tier of speed, offering a slightly more manageable but still very potent offensive option.
