Mitsubishi’s Tensei line of shafts have been some of the most popular in golf since the CK version was released in 2015. The Tensei 1K series debuted in 2021 with the 1K Pro White, a low-launch and low-spin model with a new 1K fiber to reduce deformation of the shaft. This 1K fiber is 3x thinner than carbon kevlar while also being more consistent. The 1K Pro Blue was added to the family in the spring as the mid-launch and mid-spin option.

Mitsubishi Tensei 1K Pro Blue wood shaft review

When you first take any of the Tensei 1K Pro shafts out of the box, you are immediately impressed with the look. While mostly black, the 1K fiber weave near the handle has a shine and depth to it that are just impressive. A simple metallic blue band separates the woven carbon from a gloss grey mid-section. The grey fades to a gloss black down near the tip, and if you install it logo down, you see very little to distract your eyes. The logo area of the shaft contains the Tensei and 1K series names in a holographic silver paint that isn’t really noticeable until you get it in the sunlight.

Out on the course, the Tensei 1K Pro Blue is smooth and responsive like you would expect from any Mitsubishi shaft. Compared to the 1K Pro White the Pro Blue is a little softer and has more of an elastic feeling to it. The Blue has a smooth feeling to it that loads easily and you can really feel the shaft build up some energy as you start the downswing.

As you progress through the swing, down to impact, the Blue offers the feel of an aggressive kick into the ball. You can definitely feel that the Blue wants to generate a little more power and ball speed compared to White or Black. With the firmest handle section of the Tensei shafts, that energy transfer doesn’t feel like it lacks control. Even with my quick tempo swing, the 1K Blue feels tight and stable.

The Blue is an easy shaft to square up as the softer mid and tip sections allow it to release easily but it doesn’t want to go hard left. Straight to controlled draws seem to be where the Blue likes to take your shot shape. Players who are looking to take a little of the right side out of play could find success with the Blue in the correct flex.

Launch and spin for me are very close to the mid-launch and spin that Mitsubishi describes. The 1K Pro Blue launches just a little higher than my previous favorite Tensei shaft, the CK Pro Blue. Center shots produced a mid-launching and slightly boring ball flight. Not as boring as some other shafts in the mid-launch category but we weren’t seeing any ballooning from the shaft. Shots hit off-center stay online well and work well with these new heads in keeping those shots online and the spin consistent.

Overall, the Mitsubishi Tensei 1K Pro Blue is a solid offering for players who need mid-launch and maybe a touch of spin to help keep the ball in the air. You will be rewarded with great performance and a smooth feel.
