"The K-Flight system. A high performance all in one flight and shaft system featuring Targetâ€™s patented twist system. The precision moulded system key features - Lightweight K-System flights are lighter than other moulded systems on the market allowing for a more consistent throw. - Patented Flex System The shaft section of the K-Flex has been designed to move if hit by another dart, reducing the chance of a bounce out. - 90 Degree Precision Our injection moulding process means the flights are at perfect 90 degree angles out of the box and through their playing life. - Durability A slight increase in thickness to the front and back edge of the flight increases durability dramatically over other flight types.
