The blade's standout feature is its RAG (Round About Grip) technology, which uses a unique T-slot handle design to dampen vibrations and create a distinct, connected feel on ball contact. This combination of speed, control, and a unique playing sensation makes it a compelling choice for intermediate to advanced attackers.

Flexibility
6.0

While not explicitly detailed, the blade's focus on combining speed with control and dwell time suggests a medium level of flexibility. This provides a good blend of power from the stiff response and touch from the slight give.

Vibration
7.5

The RAG technology is specifically engineered to absorb unwanted vibrations. While feedback is present, the design prioritizes minimizing harsh or disturbing sensations, resulting in a cleaner, more refined feel on impact.

Quality
7.5

The blade's build quality is considered good. While it offers strong performance characteristics, some players have noted that durability, particularly concerning the unique handle construction, could be a point of consideration. Its value proposition is often seen as favorable relative to its cost.

Technology

Joola K4 features the proprietary RAG (Round About Grip) technology. This involves a unique T-slot engineered inside the handle shells using computer-controlled precision. The design creates enlarged dampening zones and reinforces the transition from handle to blade, actively absorbing disturbing vibrations. The result is a unique playing sensation that enhances player feedback and connection to the ball, aiming to improve control without compromising the blade's inherent speed.
