Looking for more consistency from your iron game? You need to seriously consider the Pinhawk SL single length irons! They are extremely popular for a reason.

What exactly is the difference between a “regular” iron set and a set of Pinhawk SL Single Length irons? Well, as you probably know, a conventional iron set has ½” length increments between each club. This forces the player to “learn” many different swings throughout the iron set, and ball striking consistency can be an issue. The Pinhawk SL irons are a solution to that problem. The SL’s are all the same length throughout the entire set. In addition, the 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 each iron in the set.

The Pinhawk SL’s not only are all the same length, but they also feature the very latest in iron technology. They incorporate a game improvement design without looking “clunky”, and they have extreme perimeter weighting and a true deep undercut for the ultimate in forgiveness.  And despite having a game improvement design, the SL’s have a very manageable sole width, and a low (3 mm) offset on each iron.

The loft gapping is slightly larger than traditional irons; this is to maintain a proper distance gap between clubs. You will find that your distances will be very similar to a “conventional” set of irons (studies have proven that, along with "real world" play).

Our suggested length for the Pinhawk SL’s is 37”, which is a typical 7 iron length. We can also build them for you as long as 38” (a normal 5 iron length), or as short as 36 ½” (a normal 8 iron length).  Our club builders are experts on this concept and have the accredited skills to build a well balanced set of irons at any of these lengths.


Frequently Asked Questions:


Are they USGA legal?

Yes. They are listed as conforming irons on the USGA Informational Club Database, listed under Pinhawk, right after Ping.


What handicap are they good for?

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.


Has anyone I know played single length irons?

Depends, do you get out much? Moe Norman, who is considered one of the best ball strikers of all time used single length irons. Also, Bryson DeChambeau won the NCAA Individual Championship and also the US Amateur playing single length irons. With his US AM win, we are excited to report that he will be playing in the Masters, U.S. Open and Open Championship with his single length irons. Can’t get any better “proof of concept” than that!  For a little more on Bryson, you can see a USGA article here, a picture of his clubs here, and a video that talks about his single length irons here.

UPDATE: Coming off a great showing at the Masters (winning low Am with his single length irons) he has now turned Pro, and we look forward to watching his career on the PGA Tour with great interest!

ANOTHER UPDATE: Bryson wins the DAP Championship and is now a full time member on the PGA TOUR! 

YET ANOTHER UPDATE: Bryson wins the John Deere Classic! Single Length irons are now officially PGA Tour winners.

We're also excited to mention that Gareth Shaw, a European Tour player is putting the Pinhawk's in play! Gareth is no slouch, he's finished 5th in the Irish Open, beating the likes of Donaldson, Lawrie, Willett, Bjorn, Molinari, Harrington, and 13th in the French Open, beating Dubuisson, Poulter and more big names. We are looking forward to see how Gareth does on the Tour in the future!


Have any studies been done on the efficacy of single length irons? 

We just wanted to get the word "efficacy" in a sentence. But seriously, the answer is yes. 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 a study on constant length irons. If you have some time, grab a cup of coffee and read Dave's extensive academic investigation here

UPDATE: Mr Tutleman wrote a new article detailing his experience of personally playing the Pinhawks. The article is here, if you have time take a look. In short, they are "in the bag"! 

You may also want to check out some press we've been getting from this article in Golf Digest and this article from the LA Times. 


Do you have any competitors for Single Length Irons? Who else sells them? 

We do have a few competitors. The only one that we feel has the quality and expertise behind their product is found here. If you don't purchase from us, we urge you to purchase from them. 


What length is best for me?

We suggest 7 iron length (37”); that is generally the “sweet spot” for most players.  If you are exceptionally tall or short, however, 37” may not be for you. Here is a very general WTF (wrist-to-floor) chart to get you started. For more details on how to measure your wrist-to-floor, look under “Club Length” of our fitting page.


Wrist-to-floor Suggested Pinhawk Length
27" to 32" Email Us For Recommendation
32" to 34" 8 Iron Length (36 1/2")
34" to 36" 7 Iron Length (37")
36" to 38" 6 Iron Length (37 1/2")
38" to 40" 5 Iron Length (38")


Do they come in Left Handed?

Not as of yet. Tooling is extremely expensive and we would have to sell a LOT of left handed irons to make up the cost. That doesn’t mean it’s not a possibility in the future though.

UPDATE: We caved - now available in Left Handed!


What are the lofts of each club?

Here you go:


Club 4 5 6 7 8 9 PW GW SW LW
Loft 20° 25° 30° 35° 39° 43° 47° 51° 55° 59°


Can the irons be bent?

Yes, they can. Because they are made of high quality 431 Stainless Steel, they can easily be bent up to 2 degrees.


What do the heads weigh?

Each head weighs approximately 272 grams.


What is the lie angle of each club?

62.5 degrees.


How long do they take to get used to?

It depends on the player. 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.  We are confident you will like them, and we can count on one hand any complaints that we’ve had about them.


Can you compare the Pinhawk SL specs to a regular iron set?

Sure, we will compare them to a typical iron set in the charts below. Notice how the typical iron set specs are all over the map!

What kind of steel are Pinhawk heads made of?

They are made of high quality 431 Stainless.  Our competitors use a harder steel (17-4).


Why don’t major companies do this?

Because no major manufacturer is going to take a risk and try and change the design perception of the entire golf industry. It would be too much of an uphill battle to fight to educate the consumer. Jaacob Bowden (who runs, and is a proponent of single length irons) had a sit down with a major golf company CEO and he had this to say about the subject:

"Same length has been done, personally I've been a fan but 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 not so minor get tour credibility because no product is successful at retail without it." 

So there you go. Major companies aren't going to take that kind of "risk". We aren’t a "major" company, and thankfully for you don’t have stockholders to answer to. Although we do have to answer to our wives!


Can’t I just cut all my current irons the same length?  

You could, but it won’t work. On the short irons you would have to add extensions, which would not only make the swingweight severely out of line, but make the flex of those clubs softer. On the longer clubs, you would be cutting them down, and making the flex stiffer, along with the same swingweight problems as mentioned earlier.  In addition, your loft gaps on a regular set would not be correct for single length irons.


I have trouble hitting a 4 iron, do you have any options for me? 

Yes. We designed a 4 hybrid for just such an occasion. Many players find a hybrid easier to hit than an iron in their long irons. The Pinhawk Hybrid weighs the same as the iron heads, and we can make it the same length as your irons.

Good quality club that promotes consistency
I liked the look of the club heads. The 5 iron is much easier to hit and there is very little distance loss as compared to my regular length club.
I would recommend these club to anyone who has had difficulty with consistency, particularly with the longer clubs.

17 handicap
I'm left-handed and currently have had Callaway Razr XF forged irons and Adams a12os irons..
The quality of these clubs are better than the latter ..a very pleasant surprise I did not know what to expect..
The set I ordered have the Apollo steel shafts and I chose to get the five iron through the approach wedge at the 7 iron length... I've gone out for about three rounds with these clubs and every round gets better... as usual the higher lofted clubs are easier to hit but my accuracy going left and right has improved as well as hitting the ball pure. It really does make a difference to be able to have the same posture with every iron...serious....clubs are nice..ball makes nice sound when struck...feels smooth...and yes the 5 iron does carry far..... the pitching and approach wedge have nice gapping they all do..for me anyway...
THANKS Value golf!

6ft 3in / 15-20 handicap male golfer
The single length irons are perfect for me a taller golfer who has trouble with ball striking. The consistency of one swing has shaved several strokes off my iron game. Wish they made a single length driver too.

Purchase of 4,5,7,9 & PW irons
Purchased earlier the 7,9 &PW. Recently the 4 & 5 irons. Have had great success with 9 & PW. Still working on 4,5 and & 7---too early to tell how these irons will work out for me.

Pinhawk SL Review
I just started playing golf last year, and only played about 10 rounds. That being said, my best round was a 105. I received the Pinhawk SL irons for Christmas and started practicing with them almost every day at a PGA Superstore in the hitting bays. I started getting a feel for them and got good spacing with them, hitting the 4 iron about 210 and the PW about 135. I took them out for their maiden voyage two weeks ago and shot a 92. I'm not sure if it is because of the SL irons, or the fact that my swing is getting better, but I definitely feel more comfortable with these than my old clubs. Can't wait to see where I stand at the end of the year.
