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

When are the new single length irons coming out?

Joe McManuis

Tom, True Temper have a shaft named Binary which consists of Graphite and Steel shafts with the idea that you transition from graphite to steel at the 6, 7, 8 or 9 iron depending upon your 7 iron carry distance. The graphite shafts weight 73g and the steel shafts are 88g. What do you think of his approach for your Sterling Irons and/or your soon to be released single length irons. Thanks.

David Williams

Hi, Tom. I have used Sterling SL mid-irons for a few years now, and have done some experimentation with length and performance. Currently, I use the 6, 7 and 8 irons cut to a 9 iron length (-1”)(they came to me at 7 iron length). Had to add a little swing weight to the 6, and all play at D0 after testing at up to D3. It probably seems unconventional, but I hit my Sterlings better than any other iron I have ever used. I know distance is a little less than with longer clubs, but it does not seem… Read more »

Hi Tom, I’ve been playing a set of the Pinhawk SL for a couple years now. I chose them as inexpensive transition to the single length iron. Now, I’m considering moving to Sterling because the one length club is right for me. My question is whether I might be better off with a graphite shaft? I had the Apollo acculite 95 superlite with stiff flex shaft put in my Pinhawk. I gained consistency but lost 5-10 yards distance from my conventional irons. My mishits tend to be pulls too! Most important, my wrists seem to hurt as the round goes… Read more »

Tom, I think I’m aging out of the sterling metal shafts. Feel like I’ve lost speed and some distance. I’m 51 this year. Can I go to graphite shafts easily?
And now for the whopper. Can I do a mix length set? My Sterlings are currently all 8 iron lengths. I was toying with the idea of 7 iron lengths for the 5&6 iron. 8 length for 7&8. But then progressive length shafts from the 9-Gw. I currently choke down on my 9-Gw and it feels more natural.

Mark Goldsmith

Chet, I’m 67 and I pulled the graphite shafts of of my Sterlings and went back to steel. Obviously, it’s a feel thing, but I have a better feel for the clubhead with the added weight. I used a KBS lightweight shaft. So it wasn’t a big increase, maybe 25 grams. It hasn’t really changed distance, but I imagine I have a bit more control.

Mark McGrath

Is this Chester “Chet” Morningstar who is also a goalie in hockey?

Frank Quinata

Hi Tom,
My name is Frank Q, and I’ve owned my Sterlings 5H-Sw for over a year now and have enjoyed playing with them. I hit most of the irons consistantly except for the 6i. I’m thinking of probably getting another 5h and get the loft as close to a 6i as possible. Making it almost a 6H. Is this feasible or should I try something else? 5H is my go to club


Tom, I have a 5 iron swing speed of only 75 mph and thinking of getting these with graphite shafts (old set is steel shafted irons). Wanted to get these from wedges to 5 iron but wasn’t sure I could get the 5 high enough with my swing speed. Wonder if the graphite shafts would give me a few extra mph.

I use graphite shafts (Wishon S2S white) on my Sterlings, which are at 37.5″. My iron speed is 75 mph measured with a Flightscope Mevo. If I jump out of my shoes I can get to 80, but I never ever swing that hard on the course. And even with that measly swing speed, I happily use a Sterling 5I and even a Sterling 4I. I don’t get a lot of height, but the gapping is okay even so. I play in the wind a lot, so the lower ball flight can be seen as an advantage.

when will the new clubs taking the Sterling’s place be available

Rob Thacker

Hi Tom, Just wanted to add to the chorus of people that have found improvements in switching to Sterling irons, I started playing them last Feb. While my true handicap has come down by three strokes, my simulator handicap is now down by 6 strokes (from 5.9 to +0.5), best round is a 66 on the St Andrews Old course off back tees! Since the simulator really measures iron play more than anything else I think that’s a testament to the Sterlings. One thing I thought I would post about, despite having a lot of club head speed – I… Read more »


Hey Tom there is a second hand set of sterling irons I’m looking at. I currently can not afford a brand new set but am thinking of getting this second hand set to take to my local club fitter to tweak to my specs. It’s obviously not perfect but do u think this would be a good introduction for me to one length? Also I am interested in your thoughts on Milfords version of the one length irons. TIA


Hey Tom, I live near Brisbane in Australia so unfortunately don’t really have anyone close to go and get fitted for a set of sterlings but love the concept of one length and have been wanting to try them for some time now. I have tracked down a set of used(very good condition)sterling irons 5-PW for a reasonable price. If I was to purchase them, could I go to my local club fitter and get them tweaked to my specs? Also I found a set of used Milford one length clubs, 4-LW, that have only been used a handful of… Read more »

Any clubfitter/clubmaker can modify a set of Sterlings to your specs. It might or might not involve replacing the shafts – but even if it does, shaft replacement is a routine task for a clubmaker, and good quality shafts do not have to be expensive. When I was living in the Gold Coast area south of Brisbane, without access to my usual clubmaking tools, I modified/reshafted clubs for several people using tools I got at the secondhand store. Sterling irons are among the easiest to build/refit because every shaft is the same, and the hosels are easy to bend for… Read more »


Thanks Mitch much appreciated

Todd Maksimowski

Happy 2020 Tom, so thank you for the unparalleled benchmark you have set over the years, to this wonderful game that has made it more fun & easier for all to enjoy! 😊⛳️

Rich Douglas

Me too, Tom. Don’t feel like you have to respond in case this particular thread gets huge! I’ve been a Sterling golfer for 3 years now and I just can’t imagine ever going back. The day I picked up my clubs from my fitter I went to the driving range, bringing three clubs from my old (brand new) set of Pings and my entire set of Sterlings. I hit a few of each for comparison, and then never touched the Pings again. (And I was a long-time Ping player.) Eventually, I traded them in on a starter set for my… Read more »

Jon Sponman

Hello and happy Christmas everyone, I went to a range with a trackman simulator the other day and noticed, that I have a different Angle of Attack with all my Single Length Irons. I hit more down on the ball with the higher lofted clubs. Am I doing something wrong, should I hit every club with the same Attack Angle because all have the same Length & Lie? Or is this not so important as long as my gapping is fine?

Best regards, Jon

Ryan Gromfin

I can agree that after 6 months of using the irons and loving them. Every once in a while I find myself getting tight with a 5 or 4 iron in my hands and needing to remind myself it is an 8 iron. With that said, I do swing slightly different at my 4,5,6, a little further up in my stance and a bit flatter of a swing, but not as much as if I had a traditional length. With that said…TOM in an absolutely perfect world, with the testing you have done and what you have seen, is it… Read more »

Rich Douglas

To me, changing the ball position with same-length irons invites mis-directions. Moving it back makes it more likely to hit it right, moving it forward biases a shot left. Unless those are your intention, it would seem better to leave it where it belongs; loft alone (which is the only variable we’re dealing with here) shouldn’t change ball position.

Martien Schwencke

Maybe you have to give your clubs other names forget these old numbers, they are all the same only the loft is different so I play with my 50 degrees club or with my 35 degrees or my 27… that will help you to get away from traditional thinking. You have to reprogram your brain from scratch

Tom Summerhays

I’m a little late to this discussion, but I’d like to mention a few things that might help. While I recommend the 8iron length when I build a set of Sterlings, I continue to stay in touch with my builds as they get some course time in. Almost to a person, they end up playing the same ball position, but it is not always the same position as their traditional sets 8. After they make the mental adjustments and find the best position for them, they begin to find they can still create shots with SL set. Knockdowns, high cuts,… Read more »

Dan Connelly

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″?
