MITSUBISHI CHEMICAL OT IRON-Series:
The innovative “OnTarget” iron shaft, realizing high trajectory and reduction of variation in landing point and enables aggressive shot, OT™ has been redesigned according to the number, which makes it easy to build a smooth weight flow.
More precise settings are possible from long irons to wedges.
The OT™ Iron shaft doesn’t use a traditional prepreg sheet but instead uses a new material for the golf shaft industry called Tow Prepreg. Tow Prepreg uses carbon fibers that are arranged in super-strong “bundles” (the way a steel cable is made). These bundles are impregnated with resin to create the Tow Prepreg, and then woven together like a braid.
The “braiding” technology using Tow Prepreg is incredibly resistant to twisting and ovaling and creates a shaft with no spine, so the shaft performs more consistently than a shaft made with traditional sheet prepreg. The braiding also minimizes vibration, to provide better feedback that’s so important for iron play.
