Years of research and design in the making; the Edel Single Length System SLS-01 Irons are now here. Simplify your game.

Why Play Single Length?

Traditional logic enforces the notion that variable length irons are correct and that smart people before us deciphered the most accurate way to play the game. Yet, few have questioned the reason why our clubs variate in length. Ockham’s Razor is a scientific technique or discovery tool to guide researchers and scientists which states Among competing hypotheses, the one with the fewest assumptions should be selected. In golf terms, a set of clubs that allows the player to maintain a single ball position, swing plane, and rhythm rate would provide the logical explanation to achieve optimal performance. All with a club that has singularity of length, weight, bounce, shaft weight, and shaft flex to optimize the simplicity of repeating your ideal swing.

Our hollow body design allows for a thinner, stronger face to deliver a longer, more forgiving iron design.


We used multiple materials of varying face thicknesses throughout the set to maintain proper ball speeds for each specific iron; delivering optimal and consistent distance gapping.


We have done some impressive work under the hood of our SLS-01 Irons. By progressively decreasing the size of our internal cavities as loft increases we can control ball speed; resulting in optimal distance gapping throughout the set.


Multiple step forging process allows for better grain structure in our carbon steel irons; providing superior feel.


Our hollow body iron is filled with a soft polymer material to provide improved feel, sound, and energy transfer. This also allows us to move the weight to the perimeter portions of the iron; increasing the size of the sweet spot.


Through multiple design features we were able to create a vertically progressive CG throughout the set.  Lower CG in the lower lofted clubs transitioning to higher CG in the higher lofted clubs to better control ball flight; improving launch conditions, shot dispersion and feel by maximizing head stability.


We CNC our Face, Grooves, and Internal Cavity for precise control of these important design aspects of the SLS-01 Irons.


As the industry leader in bounce education and sole design; our SLS-01 Irons have optimal sole width, bounce, and grind surface to provide the best turf interaction possible.



Developed exclusively for Edel, PADERSON KINETIXX loaded Single Length iron shafts offer optimal shot trajectories with optimized distance gapping throughout the set. Unmatched performance characteristics never before available in SINGLE LENGTH irons.

Pre-Loaded for fiber tension according to flex, weight and shaft profile. Each single length iron shaft combines strategically positioned variable kick and balance points with gradient torque and frequency progression. Optimizing launch conditions independent of clubhead loft, insuring the golfer of an optimal fit option throughout a set of single length irons, independent of the golfers swing or club loft.

Paderson Kinetixx Loaded Single Length iron shafts are an innovative three (3) shaft constant weight design. Long, Mid and Short shaft profiles are designed to harmonize trajectory and optimize distance gapping in all corresponding lofts.

Mirroring performance of the mid irons, long irons are finally easy to hit and more forgiving. Flying higher and longer with more spin and increased ball speed as compared to conventionally built sets of irons having longer playing lengths and lighter head weights. The shorter iron profile generates precise distance and target control accuracy; optimizing launch conditions and playability as never before seen in a set of irons.

SINGLE LENGTH iron shafts custom-fit to produce one trajectory for superior down range target performance!

Custom Fitting

We have created the most comprehensive Single Length Iron fitting process in the golf industry. Using a combination of club heads, along with our proprietary zero-obstruction hosel adapter we can interchange over 27 shafts in various lengths into each club head to determine your optimal Single Length Iron specifications. Multiple loft, head weight, and lie angles options allow you to be fit with an iron that will be built to the same specifications.


4, 6, 8 and S Irons in 60°, 62°, 64°, and 66° lie angles provide you with the industry leading toolbox to fit your ideal set of Single Length golf clubs.


2, 4, 6, 8, 10, 12, 14 and 16 gram weights allow fitting for ideal head and swing weight during the process. Get fitted with the club that will be built for you. See instant down range results.


Replace and test out multiple shafts with ease using our proprietary hosel adapter. Tool free and simple to use with no visible change to the hosel appearance.


The design of our Single Length System Shaft with Paderson Shafts provides the perfect engine to make this concept outperform anything available to this day. This shaft is designed exclusively to be used with the Edel Single Length System. The Edel fitting system is made up of a total of 54 shafts.
