One Iron Golf System

Designed Advantage

Through the application of physiology it can be found that there is an ideal swing posture/swing plane that optimizes your skeletal and muscular functions to maximize both power and control in your golf swing. Through extensive testing performed at the One Iron Golf Testing Center we have found conclusively that the ideal swing posture and swing plane for iron play is produced through the incorporation of a 63.5º club-head lie angle. The combination of this lie angle with your properly fitted club length forces you into this ideal swing and posture resulting in complete skeletal and muscular optimization. Since a set of 1 Irons are custom built to your ideal single club length in relation to the ideal lie angle you will be assured of a stunning increase in your level of ball striking consistency, power, and accuracy. You will be as confident hitting your #3 and #4 irons as you are with your #9 iron and wedges and will gain distance with every iron in your set over your old irons.


We offer our proprietary optimized steel shafts in our irons (Black Steel in our Blackstone irons and chrome plated in our other lines).  Our driver is shafted with our proprietary optimized graphite shaft. The design of our golf shaft in combination with our proprietary Shaft Optimization Process produces a perfectly balanced golf club (all other brands use stock shafts with no balance criteria whatsoever). Once this perfect balance is achieved the concept of shaft flex (frequency) disappears and the golf club will perform at its peak performance level regardless of swing speed or strength. Our golf clubs are played by golfers with extremely high swing speeds and with very low swing speeds. In either case the golfer will realize their optimum distance, trajectory, and control/accuracy.

We are the only golf club manufacturer to perform shaft flex plane orientation (Spine Align/Puring)  as part of our proprietary Shaft Optimization Process. If a golf club is shafted without regard to its inherent flex plane the shaft will try to rotate around its axis to a position of stability during the swing which creates an oscillation of the shaft and club-head. This oscillation results in the club-head literally wobbling through impact. When the shaft is correctly oriented with respect to its inherent flex plane it will resist twisting to any other position when placed under load and will remain stable through impact. It is as if the club-head is riding on rails through the impact zone resulting in a much higher degree of ball striking consistency with a maximum transfer of power at impact.

Shafting Misconceptions: 

Senior 'flex' or any other type of flex rating in a conventional set of irons is misleading. The first few irons will be senior flex but as the shafts are cut down, they become max stiff. You can test this by grabbing your lowest numbered club by the club head and grip, bending it, then doing the same with one of the wedges and you'll feel it. 

Our goal has always been to provide the most accurate and consistent set of clubs in the golf industry, and the fact is that graphite shafts for iron play simply do not measure up to the performance level of steel shafts in any category. A common misconception is that the lighter weight of a graphite shafted club produces an increase in swing speed and, hence, increased distance. This is a myth in that the normal human tendency is to swing a lighter graphite shafted club with the arms where little power is generated along with a decided loss in control/accuracy. Conversely, the tendency is to swing a slightly heavier steel shafted club with the upper body which produces the highest degree of power and the highest degree of control. As to feel, due to our proprietary Shaft Optimization Process our steel shafted golf clubs actually feel more comfortable than graphite shafted models and produce the increased consistency and playability that steel shafts are known for. It is worthy to note that many of our customers are former graphite shaft players.


We only install our 1/8” oversize grips produced exclusively for us by Lamkin. We have found through our testing over the past twenty years that this type and size of grip produces a much greater degree of surface to skin contact than standard grips which allows for a greater transfer of swing force and a much higher degree of control and accuracy.

Quality Control

Our golf clubs are manufactured in the USA and every club goes through a twelve point quality control inspection process before being shipped to the customer. This is unlike all of the other brands who mass produce their golf clubs through factory assembly lines in China by unskilled Chinese workers with very little quality control inspection whatsoever. Our golf clubs are custom built by highly skilled club-making professionals who constantly check and double check the dynamic and custom fitting specifications for each individual order and we keep these specifications on file forever.​

Consistent Distances​

Unlike conventional golf clubs, 1 Irons are designed with a consistent incremental 4 degree loft angle progression between successive clubs. This means that since you are using the same swing and ball position with each club you will get an exact and consistent yardage gap between all of the golf clubs within your set. This can only be achieved with a single-length set of golf clubs and certainly not with a conventional set where the incremental loft angle progression varies from club to club.

Single-Length irons were used to win four times on the PGA Tour over the past couple of years which validates what we have been promoting for over two decades. We began developing the concept of Single-Length play in 1997 when we coined the term Single Length Irons, and up until just the past few years we were the only ones in the golf industry who offered Single-Length golf clubs. Once our research, testing, philosophy, and golf club designs had been tour proven and our concept of Single-Length play had become immensely popular with golfers world-wide, a number of brands sprung up to “jump on the bandwagon” so to speak. None of them had any experience in Single-Length theory or golf club design and simply put sets of clubs together based upon conventional golf club design theory which simply does not work in the context of Single-Length play. Yes, there is a reason we have been in business for over 20 years and our 1 Irons considered the Gold Standard of Single-Length irons in the golf industry.

In the decade prior to the turn of the century our founder, David Lake, began developing, what later would become, the One Iron Golf System and the basis for Single-Length play.

David Lake founder of 1 Iron Golf

David, a highly regarded professional golf club designer, had always been skeptical of the need for the standard 1/2 inch length increments between clubs within a set of conventional golf clubs. Acting on this skepticism, David began an in-depth study of the dynamics of golf clubs in relation to playability. Early on it became apparent that the progressive incremental length increases between successive golf clubs had no affect on distance but a progressively negative affect on playability. David knew that there had to be an easier, more consistent approach to the game and the answer was that all of the golf clubs within a specific design grouping (ie: irons, fairway woods) should be built to the same club length with the same clubhead lie angle, weight, shafting, offset, bounce angle, etc. And, extremely important, the clubs should be custom fitted to the individual golfer.

In 1998 David published the results of his findings in his book One Iron Golf…the common sense approach to better golf,” (free download). Since that time David has been featured in many golf magazine articles and media interviews and is recognized as the world’s foremost authority on single-length golf club design. His 1 Iron line of golf clubs continues to be the Gold Standard against which all brands of single-length golf clubs are judged.
