Engine Edition

Engine is a precision-engineered fidget spinner conceived by Nine Hands and meticulously designed by Master Duankong. Drawing inspiration from the engines of the Boeing 787 and J-20 fighter jet, its front turbine design mirrors aircraft rotors, while the rear fan-inspired locking structure echoes propeller blades, blending aeronautical engineering with everyday carry art.

The Engine Fidget Spinner is not just a spinner — it’s a fusion of aviation-inspired design, precision engineering, and EDC artistry. A must-have for collectors and enthusiasts seeking both aesthetic appeal and mechanical excellence.

A Legendary Series

Known among enthusiasts as the “King of Tuning Forks”, the Engine series debuted with the original Large Engine in May 2022.

Current circulation is extremely limited, with fewer than 199 units available on the market.

Materials including steel, titanium, and zirconium have been officially retired, making this series highly collectible.

As a flagship in Duankong’s EDC fidget spinner lineup, the Engine remains a timeless classic for collectors and players alike.
