Black Knight Ion Cannon Squash Racquets have been designed with British Open Champion, David Palmer, and feature NCT technology.

The Black Knight Ion series of racquets use Nano-Crystalline Technology (NCT) as an additive to the polymer structure of the graphite frame, for reinforcement at key stress points while allowing for finetuning of the weight and balance. The combination of NCT with the Ion frame geometry also effectively reduces frame distortion and torque for a larger sweetspot and greater control for hard hitters such as Palmer.
