Why Single Length irons?

Simply put, one length means one swing.

A conventional iron set has ½” length increments between each club. This means the player must learn different swing paths for each iron in the set. What’s more, ball striking consistency can be a major issue with a traditional, multi-length irons.

Pinhawk Single Length Irons are the solution to this problem. The clubs are all the same length throughout the entire set. That means swingweight and flex are also the same. This allows the golfer to use the same swing, on the same plane, with the same feel, for every iron in the set. The result? Greater consistency and ease-of-play, making the game of golf that much more enjoyable.

Game-improvement design

Pinhawk Single Length irons feature revolutionary technology. The heads incorporate a game-improvement design without that “clunky” look. In addition, they have extreme perimeter weighting and a true, deep undercut for the ultimate in forgiveness. Despite their game-improvement design, they have a very manageable sole width, and a low (3 mm) offset on each iron.

The loft gapping is slightly larger than it would be with traditional irons. This is to maintain a proper distance gap between clubs. You will find that your distances will be very similar to those of a conventional set of irons.

Our suggested length for the Pinhawk Single Length Irons is 37”, which is a typical 7 iron length. We can also build them as long as 38” (5 iron), or as short as 36 ½” (8 iron). Our club builders are experts at making clubs using this concept and have the accredited skills required to build a well-balanced set of irons for any player.

Frequently Asked Questions:

Yes. They are listed as irons that conform to USGA standards on the USGA Informational Club Database. They are listed under Pinhawk, right after Ping.

All handicaps. We’ve had success with these irons from hackers all the way to club champions. They help with consistency, and any golfer can use that.

Moe Norman, who is considered one of the best ball strikers of all time used single-length irons. Also, Bryson DeChambeau won the John Deere Classic with SL irons, meaning they are now officially PGA Tour winners. We’re also excited to mention that Gareth Shaw, a European Tour player, is putting Pinhawks into play.

Besides being proven by real-world play, studies have been done to prove that they are a concept that works. Dave Tutleman, a veteran golf industry engineer, did research on constant-length irons. Read Dave’s extensive academic investigation here.

Mr. Tutleman also wrote an article detailing his experience with playing Pinhawks. The article is here. (In short, they are “in the bag”!) You may also want to check out press we’ve been getting from this article in Golf Digest and this article from the LA Times.

We do have a few competitors. The only one whom we feel has similar quality and expertise behind their product is found here. If you don’t purchase from us, we urge you to purchase from them. Keep in mind, they only sell assembled clubs.

Follow the shaft manufacturer’s tipping instructions for a 7 iron. For example, if you are building a set with True Temper Dynamic Gold shafts, they recommend tipping 3” for a 7 iron. You would tip trim ALL the shafts in the set at the same 3 inches off the tip. Remember, all the heads are the same weight. Then butt cut to your length. It’s as simple as that!

We suggest a typical 7 iron length (37”); that is the “sweet spot” for most players.  If you are exceptionally tall or short, however, consider your “wrist-to-floor” measurement. For more details on how to measure your wrist-to-floor, look under “Club Length” here.

Yes. We also offer left-handed #4 hybrids.

Because they are made of high-quality 431 Stainless Steel, they can easily be bent up to 2° upright or 2° flat.

We’ve had some shoot low scores right out of the gate, and we’ve had some say that it takes a few rounds for their brain to get used to the concept. Ultimately, it depends on the player.

No. The short iron heads would be too heavy, and the long iron heads would be too light. This would cause a multitude of problems. Unless you are adept at grinding and are very creative with your weighting, it is truly impossible. In addition, your loft gaps on regular iron heads would not be correct for single-length iron application.

Basically, major companies aren’t going to take that kind of “risk” and attempt to change the design perception of the entire golf industry, nor are they willing to take the time and expense to educate the consumer.

Jaacob Bowden (who runs swingmangolf.com, and is a proponent of single-length irons) had a sit down with a major golf company CEO who had this to say about the subject:

“It’s a tough concept to sell. Reality: In the US golf industry there are 6 major chains that buy product that is sold to what constitutes 85% of the market. All but roughly 2-3 % of the rest is sold in golf pro shops and they are influenced by the retailers. The buyers for these major chains only buy what is played on tour, and pretty much in order of market share. Like it or not, we dance to that tune. To introduce something like single-length after investing in the design, we’d have to spend millions on marketing and… get tour credibility, because no product is successful at retail without it.”
