Details

Looking for more consistency from you or your customers iron game? You need to seriously consider the Pinhawk SL single length iron heads! 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 heads are all the same weight throughout the entire set, so that you can make the length the same throughout the set. In addition, the swingweight and flex would also be 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 heads are not only are all the same weight to be built 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).

If you are a clubbuilder building your own set, or you are in the business and are reselling assembled Pinhawks, we are confident you will be pleased! 

 

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 of your customers 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 contant 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. Keep in mind they only sell assembled clubs. 

 

What tip trimming instructions should I follow?

Follow the shaft manufacturers 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 the same 3 inches off the tip. Remember, all the head weights are the same weight. Then butt cut to your length. It’s as simple as that! 

 

What length is best for me or my customers?

We suggest 7 iron length (37”); that is generally the “sweet spot” for most players.  If you (or your customer) 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 swingmangolf.com, 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 buy some other iron heads and make the irons the same length?  

You could, but it won’t work. The short iron heads would be way too heavy, and the long iron heads would be way too light. This would cause a multitude of problems. Unless you are adept at grinding and are very creative with your weighting, it's not possible. In addition, your loft gaps on regular iron heads would not be correct for single length irons application.

 

My customers have trouble hitting 4 irons, do you have any options for them (or 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 you can make it the same length as your irons.

Great heads!
This is my first set of clubs that I have ever built. It was fun to put them together and play them this summer. By far the most consistent rounds of golf that I have played. Extremely accurate and forgiving!!!
I built the 4-LW but ended up keeping the 6-LW in the bag. The 4 and 5 iron came out extremely low for me.
I hit many balls extremelty close throughout the summer. However, I ended the summer with 3 holes in one.
All my friends that hit them made comments about how much they liked them.

Seems like a good idea...
...to use the same, 7 iron swing for all iron shots. I built 4-PW hybrids and 6-SW irons (iron head price is on the high-side). I am mixing and matching, but I shot a 38-40 yesterday, best round in five years....

So far outstanding
I have only played 2 rounds with these clubs that I built. The first round was average. I practiced on the range one day and played a second round. I kept my swing smooth and relaxed. I hit the ball closer to the pin and the shots felt solid. Love the clubs with the Apollo Specter Lite shats at 37.5 inches. Straighter than my Taylor Made Burner 2.0

Great opportunity to move your game up a level
I bought a set of these from Valuegolf the first week they came out, this is my second review after a year of using the clubs. My experience with Valuegolf was excellent - in fact I only ordered 9 heads but got 10 (didn't expect a LW, but it's finding a place in my bag for flop shots off the top of a hill on a tight green, thanks. I started out with shafts that were too stiff, and my initial thoughts were that I lost distance compared to my conventional length clubs, I added a 4 and 5 hybrid to my set and that helped fill the gaps of distance - this head really performs well with shots slightly picked off the turf and a flexible tip shaft. Your divit should be less than a beaver tail with lots of roots showing, making the length of your shaft is very important. I have tried a couple different shafts and I would recommend any shaft that has a reputation of playing a little softer. I ended up pulling the 4 iron out of my bag and replacing it with the single length hybrid 4. I had previously played a set of kzg evolution forged irons and had to learn to strike the ball properly to use them. This set has forced me to learn ball striking on a different level. It has also helped me to learn and play a few shots I never would have tried with my previous set. Despite my mention of ball stricking affecting my shots, I have never had more confidence chosing a club to challenge a flag hidden behind a bunker. The distance gapping of the irons is excellent, I get 100 yards with a PW and 150 with an 8 iron - exactly what I had with the forged irons. I'm struggling with consistency with my 5 and 6 irons, but a little bit more disciplined take away and transition would have me striking the ball more effectively. I chose to try this single length phenomenon because I wanted precision in my distance gapping, and I have achieved that. My scores have dropped ten strokes in one season with numerous birdie putting opportunities (my putter is next to be replaced with a few lessons and some extended practice) I would recommend Pinhawk to anyone who wants consistency with distance gapping and is willing to put in a bit of effort to perfect a single swing.

Good so far with one draw back.
This is my first experience playing with single length clubs. I have played 4 rounds so far and am still getting use to my clubs. That said, I have been averaging 3 to 4 strokes less per round. I attribute that to more consistent shot making and getting into less trouble. I really like the 4 hybrid. I have been playing for 45 plus years and for the first time I have a club that I know where the ball is going every time.
The only negative so far is 3 of the irons have developed small rust spots. Two on the front and one on the back of the heads. As I said, I have played golf for 45 plus years, I have had 10 to 12 sets of clubs in that time. Some were OEMs and others were knockoffs and I have never had an issue with rust, and after only 4 rounds.

Made Pinhawk SL heads: 5h, 6,h, 7, 8, 9 irons at 37" with Integra graphite shafts. This is my second set of Pinhawks. The 5h and 6h were a great choice for an older, slower swinger.

I have been using a set of Pinhawk SL single length irons for over a year and have seen my scores decrease from the low 100s to the high 80s, primarily due to the increased accuracy of my irons (although there are other factors that you can read about in my single length irons journey).

I often play with random people when my regular playing partners are unavailable. I never bring up the subject first, but in every single case, I’m asked about what irons I’m playing after a few holes. Most people have heard about single length irons, but didn’t really understand the concept or believe that they would work on the golf course. It usually only takes a few minutes to explain, but what really convinces them is the accuracy of my iron game.

Review by Single Length Irons Guy / (Posted on 5/4/2017)
Excellent results so far.
Early in the learning process for me but so far I'm very happy with the results. The biggest surprise we're the wedges at full swing. I got more distance due I'm sure to the club length, but not important is the consistent distance. This leaves some issues to chip but i have replaced the sand wedge with a standard version to help there. One negative is the 4 iron was a couple of degrees strong and too low for me to hit. After correcting it flew better but in my case no advantage over the 5 iron (and 5 only 6 yards longer than the 6) so I will be hitting 5,6,7,8,9,P,A,L with conventional 56 and 52, 5wd, 7wd. Now I'm in the five wedge club? Taking out my 3 wood for count may be another blessing.

Surprisingly consistent shots with these clubs. Will stay in my bag.
I tiptoed into this by purchasing the 4, 6 and 9 irons. Once built, I tried them out and was pleased to find that they were not "strange" to hit. Built to standard 7-iron length, they were easy to set up with and I found them easy to hit. I ordered the remainder of the set.
As you would expect, the short irons (8, 9, PW) fly very, very high and the long irons (5 and 4) fly a good bit lower than regular clubs.
The thing that stands out for it is that these clubs hit very straight (accurate) shots time after time. Distances are similar to normal irons. Maybe a tad longer.
The clubs seem to be a bit softer than most cast stainless steel clubs. The seem to pick up small scratches on the face fairly easily. Again, since they are bendable, a softer metal was not a surprise.
I'm still working on a really solid 7-iron swing, but can see a lot of progress.
I was playing Mizuno JPX irons prior to these and I think these will improve my game.

Great option for replacing longer irons
I bought a 4i, 5i and 6i and paired them with the FST 125 staff trimmed to stiff flex. I decided to make a mixed set with standard length 7i - PW and single length 4i - 6i and so far it has worked out well for me. Playing a 4i that is only 37 inches in length gives much better control and helps me hit more consistent shots, over 200 yards. These club heads are a bit beefy (thicker top-line and longer blade length) compared to the Acer XV Tour heads I am using on the 7i thru PW. But the minimal offset is nice and inspires confidence at address. With the shaft and grip we are talking $28 per club. A great value and very quick shipping here in PA.

Top Shelf
I am a Class A clubmaker 20+ years, and semi retired now. I bought the pinhawk set about 4 months ago.
The first impression was a good one, I checked the weight 4-PW, 2 of the heads were 1 gm light, the others were spot on, in 20 years I've never see or checked any set to be that close, loft/ lie none of them was more than 1.5° off of spec. I put some light weight true temper shafts spine and frequencied, I love them, yardage is very close to my normal length set, but the more I play these the better they get.I can't water for the hybrids and far way single length set to arrive. Get you some you will like them
