Mitsubishi Rayon's Kuro Kage shaft has undergone significant changes in the last two years, starting with the inclusion of TiNi Fiber Technology in the tip section of the Kuro Kage Silver TiNi Series that reinforced the graphite.
The elastic wire has the ability to stretch and regain its original shape to efficiently transfer and unload energy. In addition to creating efficient energy, the wires create extra strength and stability, reducing shaft deformation at impact.
The unique Titanium and Nickel alloy has become a shaft staple for other versions, including Kuro Kage XTS (extra stiff tip section) and XMS (extra stiff midsection) that feature a longer 13-inch application of TiNi wire prepreg in the tip section of the shaft.
As Mitsubishi has continued to learn more about the technology benefits behind TiNi wire, the application process has changed.
The latest example comes from the company's Kuro Kage Silver Dual-Core TiNi shaft that made its TOUR debut as a prototype at the PGA Championship.
Instead of going with just one layer of TiNi wire, a second TiNi power core was added to the tip section, doubling the amount of wire for even more stability and control than its predecessor.
Stabilizing the shaft even further is a Low Resin Content Prepreg (LRC) that possesses up to 15 percent more carbon fiber to make the overall profile stronger and improve feel.
The mid launch, low to mid spin shaft still features a soft tip section and moderately firm butt section that's in line with previous Kuro Kage bend profiles.
Mitsubishi Rayon's Kuro Kage Silver Dual-Core TiNi prototype shaft remains a Tour-only model that's available in 60, 70 and 80 grams in the TX flex only.
