A Unique Set Design to be Built to One Length for all Clubs to Deliver a Perfect Match of all Elements of Swing Feel for shot consistency.


    • Single length construction ensures all possible elements of swing feel are identical for each club in the set – same MOI, same total weight, same headweight, same balance point – to offer the chance for improved shot consistency
    • Identical length and lie allow the golfer to use the same stance, same posture, same swing plane forimproved shot consistency
    • Optional high COR #5 hybrid with high COR #4, 5, 6, and 7 irons offer proper distance for the low loft clubs at the shorter single length. Other single length sets may lose distance with the low loft clubs
    • Conventional cast carbon steel in the #8 to gap wedge with 5* loft increments blend with the high COR design of the low loft clubheads to offer proper distance gaps and proper
      distance with the high loft clubs. Other single length sets may generate too much distance with the high loft clubs
    • Available in a #5 hybrid or #5 iron to match the player’s desire and ability, with #6 to 9, PW and Gap Wedge and Sand Wedge
    • Sterling Irons® Single Length clubs can be built to 36.5”, 36.75 or 37” length for each club as fit by the Clubmaker for the golfer’s comfort and preference. Contrasts with most other single length sets being created for a 37.5” length – which can generate too much distance with the high loft irons
    • Intended to be custom fit with any Wishon Golf S2S iron shaft model and flex to meet the swing speed, transition/tempo and release point of the golfer.
    • Sterling Irons® hybrid uses standard iron shaft (.370)
    • The #4 iron should only be used by golfers with a #5 iron clubhead speed of 85mph or higher to be able to make the club generate the proper trajectory and height to be able to carry the ball further than the #5 iron
    • Available in RH (#5 Hybrid, 4-9, PW, GW, SW) & LH (5-SW); New Blade Wedges (LW, SW) available in RH only

Hi Joe, I’m not that far from you and have been a Wishon dealer for a long time. I am confident that I can help so please reach out to me for any additional info.

I have know Tom for a long time and have built many sterling sets.


Thanks for taking my call and expanding my knowledge. I’ll be seeing you soon!


HI Tom,
I’m sure you’ve seen the excellent YouTube review by Ian Fraser and Matt at TXG in Toronto.
TXG is not a Wishon Fitter but they are local to me. Would it be possible for me to buy 5i-GW heads from your company directly and take the heads there to be fit?
Also, I saw in the YouTube video comments that you are releasing a SL GEN2 set in January, is this official or just a rumor?


Tom, I want to re-shaft my sterling irons (LW to i4 at 37″) from graphite to steel. Do I need to get 10x shafts in 37″ or could I get a set for variabel length and cut it down to 36,5″?


Hi Tom.
I’ve bought a Stirling Set 4-SW a couple of years ago. The results with these clubs are impressing. I really like to play my blades Mizuno MP-18 but compared to the Stirling irons, the consistency is not as good as with the Stirling’s. For me, the optimum would be a mix of playability with the Stirling’s an feel of a forged blade like the Mizuno’s. Do you plan to launch/invent a single length, forged iron set?
Take care,

Ted I

Tom, I got your single length irons soon after taking up golf. I’ve tried other clubs but always come back to the Sterlings for my most consistent game. The problem I have is that, even though I’m not tall (5’10”) I still feel uncomfortable bent over to proper “golf position.” This discomfort leads me to feel like I’m bend over and squatting too much (think sumo wrestler stance for what it ‘feels’ like) which then hinders my ability to rotate and move my body weight. I say ‘feels’ because I look to be in a normal golf stance but it… Read more »

Rich Douglas

Ted: Your clubs should fit you, not the other way around. Depending on your setup, you might benefit from a longer shaft which, in turn, will affect your lie angles. But a competent club-fitter can take care of all of this. Also, your Sterlings are quite “bendable” for lie angles, so they should accommodate the adjustment. (Longer shafts with the same arm-length and swing and distance from the ball should be less upright.) You’ll also have to consider the impact on swing weight. A longer shaft is a heavier shaft, so it will feel different because the balance point will… Read more »


Dear Tom I purchased my sterling irons in Jan 2018. I have to say they’ve been great, you no doubt hear this all the time. I started playing just over three years ago, being new to golf I found the sterling’s much easier to hit. I’ve gone from a 21 handicap down to 9.9 and consistently shot in the late 70’s. The sterling irons have simplified my game, they make practising much simpler too. If you ever build a v2 model might you consider the following modifications: 1: slightly smaller head size, blade length. 2. sound/vibration absorption on the back… Read more »


No need change about sound/vibration. I love this feedback, i know i make a good shot when i hear this.


I agree. Before buying my Sterlings I had heard comments from others discussing the ‘ting’ you hear with the High COR 4-7 irons. I was starting to get worried about it. Well when I finally tested my set, I must admit, I REALLY like the sound. As Richard said above, I know when I hear it I made a more solid strike. Plus, the combo of the feel of hitting the sweet spot AND hearing the distinctive ‘ting’ is something I look for on EVERY shot.


I have played sterling irons for about one year now and my iron game Has considerably improved. My clubs were fitted by Andre thaon who made the length of my previous 8 (771). My distance with the 6 iron being 125 m (110 y) do you think i could play a 5 iron?
Thanks for your answer,

Joe McManuis

Tom, I have seen recommendations to have wedges fit with a flatter lie than the irons to 9i. What is your view on this and if you agree then generally how much flatter? Thanks.

Ryan Gromfin

It just so happened that after my sterlings were built, when I went in for a gapping session we found that I was pulling my wedges so we flattered with them a bit. I am not sure if that is a standard thing or has to do with the longer wedges, but it has worked great for me.

Leon lee

Do you have left hand clubs? Tks


Hi Leon,

Yes, the Sterling Irons are available in Left Hand in #5-9, PW, GW, SW.

Hope this helps,

Richard H Bragdon Jr

Can you tell me the bounce of the original Sterling lob (60 degree) wedge?


Hi Tom, is there a reason Sterling Irons aren’t offered in an X Flex? Do single length irons not work that well with stiff low launch shafts? I was fit for one length Cobra F9’s and KBS Tour 130 X shafts at 37.5″ I love the GW through 6 iron, but then hit the 5, 4, and even the hybrids on too low of a trajectory and don’t get much farther than my 210 yard 6 iron. In case it helps, I’ve got a 93 mph swing speed with them (115 driver). I have a quick transition and while my… Read more »


Hi Tom,

Got a set from a friend and length is 37″.

Will there be a difference if i cut down to 36.5″?



Hello Tom,
I’m looking to purchase the SL in LH and I can’t find a fitter in the Chicagoland area, so I’m going through the website. I have tried the 1 club fitter suggested here but no responses. Do you have any recommendations? Or should I just go with my previous specs? My current 8-iron is 36.75″. I’m not sure what adjustments can be made through the online purchase?


Was wondering how your SL wood/hybrid project is coming together? I play the Sterlings 4-SW including the hybrid. I’m specifically interested in how your thinking about swing speed vs length. My driver speed is 100-105. Based on this what is the shortest feasible length to play driver, fw woods and hybrids ?

PAT Yes it is coming along fine with the expectation for very late winter to early spring 2020. The woods will be set up at an initial design head weight that will allow assembly either to normal lengths or with the additional internal weight addition capability they will be able to be made to be a single length of 40-41″. The woods will be available in #3, 4, 5, 7 but there won’t be a driver. You just cannot make a driver to be as short as 40-41″ and have it ever be able to generate a distance that a… Read more »


A friend on mine wants to sell me his used set of Sterling Irons. I might need to customize them to my swing speed and FTW measurement. I have a normal club speed of about 80 and my FTW measurement is 34.5 . His old set is 36 1/2 in club length, and the marking on the shaft has the following — A Flex Iron, SwSpg 55-65, WGT 73 G, TRN 2.225, TEM 2.225, RLS 175.225, STRGTH 175.2. The question I have is wheather I need to send these clubs in for to be customize to my specs, or can… Read more »

Terry: You did not say whether your 80mph swing speed is for the driver or for the irons. If you are 80mph with the driver then the shaft flex is likely OK or pretty close. But if you swing your irons at around 80mph then no, you’d need a stiffer shaft for sure. The 36.5″ length is OK for your 34.5 wrist to floor measurement but you did not state what the lie angle of the irons is so there is no way to know if the lie of these irons would fit you or not. Same with the swingweight.… Read more »


Hi Tom, I’ve had your sterling set for about 3 years now. HAven’t golfed better. A question for you…for those of us that don’t have enough clubhead speed for the 4-iron, what about having the 4-iron at a longer length? I know its not “single length”..but when you go to a hybrid, it is longer also. I have the 4-iron and hit it good on the range when I really go after it, but real on course playing I don’t swing that hard, so I have it out of the bag. I was just thinking that adding a 1/2″ or… Read more »

Mark McGrath

Hi Tom – I bought a set of these used and am really enjoying them. Question on the lofts of the short irons – especially the 9 iron and PW – are they lower lofted than traditional sets due to the longer shaft length? I seem to still hit them well – just really high and wicked long for those particular club lengths. Perhaps I just need to adapt a little and shape my shots a bit more. The more I use the Sterlings the more comfortable I get and the lower my scores drop! Played 9 yesterday with just… Read more »

Ned Connell

I found this very informative. The question of who should use these irons was my question and it’s been answered. These would be my choice. I’m 84 and my consistency has gone away. I may have to give up (finally) my old 770’s and try something new.


Hi Tom,i have SLI 4 to Gap all with std flex 8 iron long. i want to add the SW and LW.
Do you recommend using the same shafts as the other SLI’s or wedge shafts?
thanks Rob

Tom Wishon

ROB Yes for sure us the same shaft with the same tip trim with the same length cut as you did with the #4 to GW. And I would recommend you do the swingweight of the SW and LW to be the same as the #4 to GW. The whole nature of single length is to have every single element that has anything to do with club feel be identical in each iron and wedge so you can have the best chance to improve swing repeatability and from that to gain shot consistency. Changing anything from the specs of the… Read more »


thanks tom


Tom, Amazing set of clubs you have crafted with the Sterling Single Length Irons. After experimenting with four different sets of one length clubs over the last few years- all with various pros and cons- the Wishon set is truly a step up from all the other options. The consistent gapping has been what puts the set far above the others for me. The gapping coupled with getting good height with the five iron has allowed me to finally dial in some scoring distances even with the “long” irons. I plan on keeping these in the bag for a very… Read more »

Tom Wishon

Thanks very much J! Thanks for taking the time to stop by to let us know how your Sterlings compare with other models. I will be honest and say that some golfers depending on their clubhead speed and angle of attack may need to tweak the loft of a couple of their irons here and there. But I will also say that in the 3+ yrs that Sterling has been out that I do believe the number of golfers who have not had to tweak a loft to achieve consistent distance gaps is very high. I think a lot of… Read more »


Hi Tom,

What are your views on 1 Iron Golf’s single length sets (more specifically the Proline version)? How do they compare to your Sterling irons?

I find it interesting that 1 Iron Golf has been around for so long (1997 I believe). I only came on to them after all the rage regarding single length clubs in recent years.

Kindest Regards,

Rich Douglas

Nathan: As a member of this community, I encourage you to read through this thread. In it you will find a great deal of information about Sterling Irons. But what you won’t find is a lot of comments from Tom about competitors’ designs–other than specs you can find from their websites. There is a great deal of information on the Web about the clubs you’re talking about, as well as a lot on other designs. When I decided to purchase my set of Sterlings almost 3 years ago, I considered other designs and found them inferior in implementation. I’ve subsequently… Read more »

Tom Wishon

Nathan Thanks very much for your interest. Single length iron sets have been offered by lesser known companies off and on since 1986. So 1-Iron Golf has been another company in that group with others that came before them. No one paid much attention to these companies or to single length in general of course because there had not been anyone at a high level of play to direct attention on the concept until deChambeau came along. The only “problem” with single length irons, or rather the main thing that a golfer has to keep in mind when considering single… Read more »

Richard Shaw

I tried 1 Iron Golf clubs in the 1980s. I found they had lest distance than regular clubs and lower trajectory. They were only “custom” to the extent of the 1 club length and had steel shafts. The club head was rather ordinary too – cannot recall the exact specs.
I have not yet invested in Stirling single length but will keep looking into it now they have left handed clubs.

Shelby Langston

Hey Tom, Back at the game after an injury and once again playing after two years.. Noticed the lob and 5h are available. Where can i find these? can i order the heads?
thanks again

Tom Wishon

SHELBY My apology for the delay in responding. I was out for a medical procedure for a week and am just getting back into the fold. If you are not a custom clubmaker, you can get the Sterling 5 hybrid and lob wedge fit and built for you and your swing by an independent custom clubmaker. To find a clubmaker near you, on our website look at the very top of the home page for the link for FIND A CLUBMAKER. click on it and input your town/city/zip and the clubmakers closest to you will be displayed. If none are… Read more »

Thanks Tom for the info. I will go have a look at Diamond Golf.

Ted Inoue

Hey Tom, wanted to add to the conversation. I’ve just started my 5th year of golf, and bought my Sterling set early on, I think during year two, because I wanted to build consistency and was having troubles with ball striking with conventional clubs. As a beginner, I’ve found them unforgiving due to their sharp leading edge and small bounce. For a short while, I switched to a new set of Mizuno Hot Metal irons, but I quickly returned to the Sterlings because of their predictability. Rather than subtly changing my alignment, ball position, etc. with every club, with the… Read more »

Tom Wishon

TED Wow, sub 80 in the start of your 5th year in the game is phenomenal, it really is. Good for you that you are having the success you are in the game. While I am sure the irons have helped with your swing repeatability and from that your confidence, in truth as the designer with a big amount of experience in swing study I freely admit the lion’s share of the credit is yours for your aptitude you must have and your work ethic to make it happen. Well done and I hope it continues to keep getting a… Read more »

Tom ~~ Any plans to make single-length left-handed iron sets? I’ve been following your company for several years now, and used to play the One Iron single-length clubs, but the gapping was never right. In the last few years (@ 62 yrs. old) I’ve also switched to the single-plane swing (Graves Golf Academy), and have been seriously thinking about purchasing a set of single-length clubs from Cobra. But from what I’ve seen of them, I think I’m convinced that your product is actually better than Cobra. If you have no plans for left-handers, then would you recommend Cobra’s product, or… Read more »

Tom Wishon

The Sterling Irons are available in left hand and have been for at least two years. However because of the lower demand, we are offering the #5 iron to original SW and not the #4 iron, #5 hybrid or the newer SW and LW in left hand. The left hand models are in stock with Diamond Golf. Thanks so much for your interest,
