AutoPOWER KHT (Korea hidden technology) applied is a new concept of the shaft that changed the common sense of the ordinary shaft. The name autoPOWER KHT refers to the power that results naturally from a balanced shaft weight and frequency. And when these factors are matched as closely as possible to a specific individual’s swing characteristics, it will naturally create the most effective club speed for more distance and accuracy for that particular individual.
