Mitsubishi TENSEI 1K Black Shaft Review - Plugged In Golf (2024)

50 Words or Less

The Mitsubishi TENSEI 1K Black shaft has low launch, low spin performance to the TENSEI 1K White. Stout, consistent feel. Great for higher speed players and aggressive swingers.

Introduction

Equipment nerds were introduced to the Mitsubishi TENSEI 1K Black this past fall via the Titleist TSR woods. This newest TENSEI was one of Titleist’s stock options, and the winner in my fittings [more on that HERE]. The wider golfing world was made aware of the TENSEI 1K Black this past January when Max Homa put one in his driver and promptly won the Farmer’s Insurance Open at Torrey Pines [details HERE]. Now that this TENSEI is widely available in the aftermarket, I thought it was time to bring you the full breakdown.

Looks

The Mitsubishi TENSEI 1K Black is exactly what you’d expect if you know the TENSEI line. You get the traditional branding in white across a matte black background. The “Multi Material” ribbon and “1K” logo sit closer to the grip on a dark grey, woven background. If you’re searching for a “Look at me!” shaft, this is not it. This shaft is made for people who let their game do the talking.

Feel

The Mitsubishi TENSEI 1K line is a great example of why you can’t fit on paper. All three of the shafts in this family – Black, White, and Orange [review HERE] – are billed as low launch, low spin, with high kick points, but they all have a unique feel.

Starting with a wide lens, the TENSEI 1K Black is a stout, tip stiff shaft. In this, it’s similar to the 1K White. Where they differ is that the 1K Black feels stiffer throughout. With the 1K White, there’s a noticeable amount of flex in the butt section. The 1K Black doesn’t have that. This is a shaft you can really lean on and swing aggressively. It stops short of being boardy or harsh, but you never have to worry about this shaft getting loose.

Performance

My first encounter with the Mitsubishi TENSEI 1K Black came at a fitting for the Titleist TSR woods. It easily bested the other options and went into a variety of drivers and fairway woods. The feel was familiar and comfortable, and its consistency provided the perfect platform for seeing the differences in heads. This shaft helped all of those woods to post solid dispersion numbers while also keeping the spin low.

Jumping forward to this review, the bar was high for the TENSEI 1K Black. Regular readers know that the TENSEI1K White [review HERE] has been in my bag for over a year and a half. It’s survived numerous challenges and has the inside track for 2023. With all those expectations, the TENSEI 1K Black still shined.

In terms of the raw numbers, I saw very little difference between the 1K White and 1K Black. Both produce very predictable numbers for launch and spin. More important to me, they gave me the dispersion that I deserved. I never looked up from a swing to see the ball doing something unexpected. Good swings produced laser straight shots, and I was able to move the ball both ways without trouble.

Where the two shafts differ for me is in how their feel affects my swing. The TENSEI 1K Black encourages me to swing all out. In contrast, that little bit of action in the butt of the TENSEI 1K White helps me to swing at just 98%. I also feel like it’s adding a little extra oomph, though that’s not something I saw in the ball speed. For players that swing aggressively and want their shaft to keep up, the Mitsubishi TENSEI 1K Black is the easy choice.

Mitsubishi offers the TENSEI 1K Black in stiff, X-flex, and Tour X. All three flexes are available in 65, 75, and 85 grams.

Conclusion

The Mitsubishi TENSEI 1K Black adds another high performance option to the outstanding 1K line. For players seeking low launch, low spin, and tight dispersion, this is tough to beat. It’s also an ideal choice for aggressive swingers who need a shaft that can match their strength.
