From the throwspiral.com website: "From the start the Kappa was designed to challenge conventional wisdom about organic profiles and the role of rim weight in performance. In a market split between casual organic yoyos and competitive models composed of harsh angles, the Kappa stands out by refusing to compromise between performance and ergonomics. Instead it borrows the best of both worlds, combining comfortable organic rims with a low-friction V-shaped inner profile. Stability is achieved through an aggressive weight distribution enabled by 7068, but the spin power is balanced with a modest total weight of 64.3 gm to maintain maneuverability. The result is something remarkable - a truly competitive organic yoyo for the modern era."
The Kappa - Adrian Esteban edition came in matte gray anodizing with a special phenakistoscope pattern engraved on the halve, designed by Drew Tetz. When the yo-yo is rotating on the end of the string, the "æ" pattern appears to be "moving". See another example of a yo-yo-related phenakistoscope pattern on Core Concept Yoyos' Alleycat Loop Diggers yo-yo patch that came with the blue Alleycat 650b - Loop Diggers yo-yo.
