US Open champion DeChambeau talks about the benefits of the One Length Iron
A logical approach to golf based on a unique swing theory Bryson DeChambeau ( ), a professional golfer who has won the U.S. Amateur, U.S. Collegiate, and U.S. Open titles and is also known as the "scientist of golf" Bryson DeChambeau
The "One Length Iron (Single Length Iron)" that he uses has a logical concept and has attracted attention in the United States. It is gradually becoming more popular in Japan as well, garnering the attention of golfers.
In this article, we will look at the One Length irons that DeChambeau himself talked about in an interview. We will explore the appeal and potential of the (single length iron).

One Length Iron What is a (single length iron)?
One Length Iron The biggest feature of (single length irons) is that, as the name suggests, all clubs are the same length.
This allows players to maintain the same position and swing no matter which club is used.
With conventional sets, players are forced to adjust their clubs to fit their needs because the clubs vary in length and weight, but ONE Length irons eliminate this need, allowing for a more logical and simple way to play.
"In 2011, we reinvented the ONE Length iron with Mike Shye. This club can benefit not only professional golfers, but anyone in the world. "
"A question I get asked all the time is, 'Why are these clubs better than clubs with different lengths?' In my opinion, the answer is because all the clubs are the same length."
DeChambeau explains the ONE Length iron concept:
"You don't have to change your body position when addressing the ball, whether it's a pitching wedge, a 9-iron, or a long iron."
"That's why I switched to ONE Length - I wanted to be able to swing with the same position every time."
"Consistency" changes golf
DeChambeau is He cites "consistency" as the biggest appeal of ONE LENGTH irons.
"Golfers need to strive for as much consistency in their swing as possible."
"With ONE Length irons, all the clubs are the same length, so you can maintain consistency and swing with the same body position, which is very important."
While you have to use clubs of different lengths to deal with the various slopes on the course, standardizing the length of your clubs reduces the hassle of adjusting your swing depending on the situation, allowing you to play more consistently.
" Using different club lengths and varying inclines can be quite a challenge."
"But with the One Length Iron, you eliminate the need to adjust for clubs and slopes, allowing you to hit the ball at different slopes. This increases the chances of hitting the ball in the center of the club face with the same swing.
Golfers who are suited to ONE Length irons
According to DeChambeau, ONE Length irons are a club that benefits everyone, from beginners to advanced players, not just professionals.
"We understand that many people have used irons of various lengths, but recently many have switched to ONE Length irons and seen a dramatic improvement in their ball-striking ability. "
How does the difference in distance come about?
In traditional sets, it is said that the length of the club affects the distance, but with ONE LENGTH irons, the loft angle plays an important role in adjusting the distance.
"The loft angle is what makes the difference in distance with ONE Length irons."
"For example, a four-degree change in loft will result in a distance difference of about 12 to 13 yards at a 90 mph swing speed. It's the physics that make the difference."
"In terms of distance, traditional irons and ONE Length irons are essentially the same. A lot of people think that club length affects distance, and that's true."
"But if all the clubs had the same head weight, they would fly too far consistently unless there was a difference in length. So with clubs of different lengths, you have to adjust the head weight and club length to get the right distance."

One Length Iron "NOOG"
Inspired by DeChambeau's "One Length Iron" concept, NOOG's "One Length Iron" was created in collaboration with Kyoei Golf, a long-established golf manufacturer with over 60 years of history .
All NOOG irons are the same length as an 8-iron.
All clubs are the same length and weight, allowing for consistent swing and address without changing body posture. We've redesigned the conventional wisdom of irons to ensure the shortest possible path to hitting the ball at the appropriate distance , which is what irons are supposed to do.
For those who can hit short irons consistently but struggle with middle irons, this club will allow you to hit both middle and long irons with the same feel as an 8-iron , leading to improved accuracy on your approach shots. The more you use it, the more fun you'll have with middle irons.
Many irons on the market are focused on "flying," but what is really required of an iron is to "hit the ball at the appropriate distance."
Being able to consistently hit the ball at appropriate distances of 120 to 180 yards using irons will lead to improved scores.
NOOG's unique interpretation of DeChambeau's theory is the "One Swing Theory."
Since you can maintain the same swing, address, and ball position for all clubs , you can now vary the distance with just one swing .
