Learn the differences between Conventional Irons and Single-Length Irons

I am constantly amazed when golfers boast about their conventional sets of irons being “custom fitted” and, therefore, producing enhanced and consistent performance. The concept of being “custom fitted” for a set of conventional golf clubs is ridiculous in that you still end up with 13 clubs (excluding the putter) of different lengths, weights, shaft flexes, lie angles, bounce angles, offsets, etc. when, in fact, your body gravitates to only one efficient movement for any physical endeavor (that is the reason why all golfers have a “favorite” iron). Therefore, after being “custom fitted” for a set of conventional clubs you still end up having only one iron in your bag that even comes close to fitting you correctly and that somewhat allows for the swing posture and swing movement that your body wants to make when hitting a ball with a golf club. As far as consistent performance goes I have to bite my tongue. The following table shows the typical specifications for a conventional set of irons (varies between brands as there are no specification standards in the golf industry).

How this equates to consistency I do not know. I would like to point out something from the above table that most golfers do not realize and that has to do with the varying shaft flexes within a set of conventional irons. Regardless of what the shaft bands state, every one of the irons in a conventional set has a different shaft flex that gets progressively stiffer from the #3 iron to the wedges. To prove this to yourself simply hold the clubhead of a conventional #3 iron in one hand with the grip in the other hand and bend it – then do the same thing with the PW from the same set and you will see what I mean.

Another thing that most golfers do not realize is that in a conventional set of irons the clubhead weight progressively increases from the #3 iron through the wedges. This results in a greater amount of mass impacting the golf ball with the wedges than the low lofted irons. Wouldn’t you want the higher impact mass associated with the iron that is designed to produce the most distance?  Enhanced and consistent performance? – Go figure.

The specifications for a set of 1 Iron single length irons are shown below. With the exception of the bounce angle on our SW the only difference between irons is the exact 4º loft angle progression from the #3 iron through the wedges. The reason for the additional 3º of bounce angle on the SW is to enhance play from a soft bunker. You may note that the bounce angle of a typical conventional SW varies from 10º to 14º. Bounce angles this high produce a clunky shot out of the sand and make playing shots from a close cut fairway virtually impossible. What is sad is that most golfers will continually blade shots out of the fairway with a conventional SW without ever even understanding why. Our 1 Iron single length SW was designed for highly effective sand play as well as fairway play, and an interesting point is that part of my design testing for our SW involved hitting balls off of a cement driveway (no skulled shots with our SW).

At the end of the day you just have to leave all of the marketing hype about custom fitting and conventional golf club design behind and simply rely on plain old common sense.

    Hello,
    My wrist to floor measurement is 39&1/2” and the longest length you have is 39”. Would that be a problem for me? I don’t plan on playing a whole lot so I would like to take advantage of the demo sets you have. I am just worried about them as there is no free trial period. Are there many people that just can’t get used to them no matter how hard they try? I would hate to be stuck with them if they are hard to use. How used/worn are the demo sets?

    Hi! You would order 39” and up, that would be your perfect size. Our irons are very easy to hit. There is a learning curve but it does not take long since you only use one swing, one ball position, and one stance. Even with the New clubs our return rate is exceptionally low because it really only takes a couple of weeks to adjust. The Used/Demos are in excellent condition, they are the same condition or better than a couple of rounds after you play with New irons, so very lightly used. Please let me know if you have any other questions, and read through our reviews!

    Hi Michael, We have 4 iron lines to choose from – and they all come in new or used/demo. Head to our Shop page and check out the set makeups that we offer. https://1irongolf.com/collections/all-products.

    It is impossible for 99% of golfers to hit a #1 iron because of the low loft angle. Our #3 Pro-line is 17 degrees which is the equivalent of any #2 iron (driving iron) on the market and to my knowledge no company makes a #1 iron. For instance PXG’s driving iron is 18° and Taylormade’s is 17°.

    We only install our proprietary steel shafts in our irons and fairway woods. The design of our golf shafts in combination with our proprietary Shaft Optimization Process produces a perfectly balanced golf club (other brands use stock shafts with no balance criteria). Once this perfect balance is achieved the concept of shaft flex disappears and the golf club will perform at its peak performance level regardless of swing speed or strength. Our golf clubs are played by professional golfers and long-drive champions with extremely high swing speeds and played by senior women golfers with very low swing speeds. This balance also greatly reduces any potential vibration of the shaft, and that, coupled with our 1/8” oversized Lamkin grips, virtually eliminates any vibration you would normally experience with steel shafts. It is of note that many of our customers are former graphite shaft players. We have a new video out on our YouTube page explaining this in more detail!

    Shipping to Canada is free is you spend over $1000 USD. I believe most of Canada charges import duties and taxes. We cover the brokerage fees. Here is a calculator site: https://www.cbsa-asfc.gc.ca/travel-voyage/dte-acl/est-cal-eng.html – these will be collected upon delivery by the shipping carrier on behalf of Canada.

    As a veteran owned company we thank our vets and first responders 🙏🙏, but in order to keep our prices we don’t offer additional discounts. We do have the used/demo blowout sale going on now – biggest discount we’ve ever offered.

    Let us know if you have more questions!
