We first saw the Diamana Kai’li at the PGA Merchandise Show in January.  Everyone gathered around the Mitsubishi area was absolutely buzzing with excitement at this latest offering from the company.Translated, the name means “blue diamond” and the design is for the more advanced golfer and gives them more ball control.  An ultra-thin, multi-layered carbon fiber material makes up the shaft – all engineered at Mitsubishi from start to finish with a technology called MDI.  This is the “multi-dimensional interlay” that strategically positions multiple layers of their proprietary ultra-thin material at multiple andles of orientation through the entire shaft. 

We found buzz about the shaft saying, “The Kai’li has a multi-dimensional design that utilizes thin sheets of carbon arranged in a multi-layer structure to control torsional stiffness, stability, and elasticity. A mixture of unidirectional carbon fiber for stability coupled with high elastic modular carbon fiber make up 68% of the shaft. The result reinforces the shaft for control and dispersion while still giving it elasticity when storing and releasing energy during a swing. The Kai’li is available in 60, 70, and 80g ranges with lower torque and mid-high kickpoints. The kai’li is designed to give harder more aggressive hitters the confidence and control they look for with a low to mid trajectory and a low spin shot.” 

The finish on the Kai’li is remarkable in itself.  This is what each angle of one shaft looks like – the color changes as you turn it:


The company touts a smooth, precise profile with stability and consistency during swing loading and unloading.  This has a slightly firmer tip with less torque than the original Diamana Blue Board.

  1. This shaft is freaking awesome. I use to game the R11, one day the Callaway fitting fan came to the golf course. They set me up on trackman, and I was hitting 265 yard carry. Set me up with a Callaway Razr Hawk Tour with the Kai’li. My carry volted up to 290, 320 total. What a shaft, makes me a better player.
