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.


  • If you are interested in the Sterling Irons® single length clubs please use the Find a Clubfitter form to find and contact a clubfitter near you, or visit
  • 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 off er 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

  1. 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,

    • 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 found two that seem interesting, but both are built around a 37″ shaft design–as opposed to the standard 36.5″ in the Sterlings. (YMMV)

      I’m sure Tom will have more to say, but I thought I’d add my two cents. Oh, and that I’ve played these for almost 3 years without ever considering going back to traditional clubs. (Averaging about a set every year, it was nice to get off that roller coaster!)

      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 length is that if his current 5 iron clubhead speed is under 75mph, he really has to be careful to not try to use any single length iron with a loft lower than 27-28* in his iron set.

      The reason is because the one length of all the irons will likely be shorter than what the length of his irons that were 28* or less in his conventional set and that will mean the clubhead speed he generates with his single length irons of lower loft will be less than the clubhead speed he could generate with his lower loft irons in the conventional length set. Lower clubhead speed with lower loft doesn’t work very well to get the ball up to fly and carry.

      This is one area I tried to alleviate a little bit by designing the Sterling #4, 5, 6 and 7 iron heads with a high COR face and a little lower loft. But no matter what, even with this if the golfer’s 5 iron clubhead speed with his conventional length 5 iron is under 75 mph, he should not have the 5 or 4 iron as part of his single length set because he will not generate enough speed with then to get those lower lofts up high enough to fly and carry a full club longer each than the 6 iron. In their place would be hybrids that would be 38 to 39 inches in length to get proper distance.

      But even with a #6 to SW single length set, you still get the benefit of having seven clubs in the iron set that will be of the same exact swing feel to potentially help improve swing repeatability which improves shot consistency with all the irons. Plus I really believe conventional length #9, PW, GW and SW are too short for most players. So going with a single length set gives you more length in those high loft irons which can really help with comfort through the ball and not having to fight staying down on the shot through impact.

      1-Iron Golf has no high COR irons in their sets. Since we introduced Sterling, I see that 1 Iron Golf are trying to offer custom fitting for length where before they did not do that. But their lengths are based on a longer single length than is Sterling. The reason I set things up for Sterling to try to fit toward a 7 or 8 iron length and not a 6 iron length as others do is because 7 and 8 iron length are easier to swing consistently than the longer 6 iron length. And also a 6 iron length for the wedges is really too long for most players. Finally, Sterling irons are sold only by people who do full specs custom fitting for ALL the fitting specs and not just length. So when all specs are fit to the golfer there is a better chance of achieving the goal of better swing repeatability and shot consistency. Hope this helps and thanks very much for your interest,

    • 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.

  2. 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

      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 convenient to your location contact them anyway because many of them can and do work via email and shipping the clubs to golfers. If you are a clubmaker you can contact Diamond Golf toll free at 844-552-3437 to open an account. Diamond Golf is located in the UK and when I went into semi retirement, they took over my product line and all distribution. They do have stellar shipping deals to make it easy to get products from them over in the UK and most all the US and Canadian clubmakers order from them. Thanks very much,

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

  4. 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 Sterlings I just focus on a good, clean swing. The more my game has improved, the more I appreciate them.
    While my game is still frustratingly inconsistent (people tell me that feeling never leaves) I had a breakthrough yesterday with a sub-80 round and overall very solid play, that I feel that I owe to your Sterling irons.

    • 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 little better each year for you!


  5. 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 is there another company of which I am not aware? Thanks! Christopher

    • Christopher
      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,
