Stiff under the hands
1K carbon fiber in the handle firms up the butt section for a stable, connected feel through transition.
Mid launch, mid spin TENSEI Pro with a very stiff 1K handle
Mitsubishi Chemical · Wood ShaftsTENSEI 1K Pro Blue sets a firm-plus, 1K Carbon Cloth reinforced handle against a smooth mid section and a stable tip with boron prepreg. The result is a mid-launch, mid-spin profile that feels solid in the hands and lets the head work for speed. It is aimed at players who like to shape the ball off the tee and want a little more ball speed.

Why golfers choose it
1K carbon fiber in the handle firms up the butt section for a stable, connected feel through transition.
Boron-infused prepreg and the Xlink Tech Resin System strengthen the tip, keeping it steady through impact.
Mid launch, mid spin and a mid kick point give a neutral window for players who curve the ball on purpose.
