The Gold Standard
of Single-Length Irons
of Single-Length Irons
Our iron lines are not built for any particular handicap, age, or skill level.
For over 25 years our 1 Irons have been the industry standard for Single-Length golf club design and performance. There is no substitute for experience!
Our cavity-backed perimeter weighted clubhead design provides a maximum forgiving clubhead experience.
All four lines are the easiest-to-hit irons you will ever own.
Our irons are not method specific and are played and recommended by conventional PGA instructors as well as single-plane (Natural Golf), PPGS, Stack and Tilt, and other swing method instructors and advocates. Regardless of the swing method or address position used the ideal position of the body, wrists, and arms are identical at the point of ball impact. Simply put, it is not important how you get to the ideal impact position as long as you end up in the ideal impact position. Consequently, since your 1 Irons, Pro-Lines, and Blackstones are custom-built to your ideal club length in relation to the ideal impact position they will produce enhanced ball striking no matter what swing method is employed. It might be of interest to note that Moe Norman (single-plane swing) played single-length golf clubs throughout his entire competitive career.
Which iron line is right for you?
You can't go wrong with any of our lines of irons since they are extremely forgiving for
golfers of all skill levels and will greatly improve your game and lower your scores. See below for specifications for each line!
1 Irons
Our original namesake iron line that introduced the golfing world to single-length play in 1997. These clubs have evolved over the years, but they continue to incorporate a denser club head mass than the other lines to maximize ball compression. You can use the same swing and ball position with every iron and on every shot for a stunning improvement in your ball striking ability. Just imagine how your game will improve when your #3 and #4 irons are as easy to hit as your wedges.
Pro-Line Irons
Based upon the proven clubhead design of our original 1 Irons, we designed the Pro-Line for the next-level golfer looking to maximize distance without compromising accuracy. This iron line is modeled after touring irons, incorporating the design features that professional golfers prefer: lighter clubhead weight for added swing speed, 2º stronger loft angles for a more penetrating ball flight, and a stiffer shaft tip section for enhanced stability through impact. Available in right and left hands.
Blackstone Irons
Our premier line of irons is without a doubt the most advanced set of single-length irons in the golf industry. Capitalize on precision and accurate shot making with the Blackstones. Proper clubface alignment at address is key when it comes to dropping approach shots on the pin. Alignment being off by only 1º or 2º either way means adding an extra 8 to 15 feet to your birdie putt. The Blackstone's bright white scoring lines against the black PVD background make club-face alignment exact and automatic at address, and shafting with our proprietary black steel shafts eliminates any potential glare at address. Old-fashioned club numbering has been replaced by the actual loft angles for precise club selection and distance control. Available in right and left hands.
Features
A custom-fitted set of single-length golf clubs produces a stunning increase in consistent ball striking, distance, and accuracy for golfers of all skill levels and is the premise of the One Iron Golf System.
Ultra Game Improvement
Independent Maltby Playability Factor (MPF) testing conducted independently by The GolfWorks resulted in our 1 Iron Pro-lines being classified as Ultra Game Improvement irons, the highest classification. The Maltby Playability Factor is the golf industry standard for iron playability classification.
I’ve recently bought a set of Blackstones and can easily say they are the best clubs I’ve ever owned in my golfing life (almost 50 years). First round back playing after a while and birdied 3 of the 4 par 3’s with almost 2 hole in ones. So close!! Highly recommended 👌🏼
5 stars all-the-way. I purchased a set of Nova irons in December. At 69 years of age, I can say that these clubs will extend my years of enjoying golf significantly. With the easiest swing, the club does the work. High ball flight with super dependable yardages.
I purchased the Pro-Line sand wedge (53 Degrees) in February to fill the gap between my old L-wedge (58 degrees) and my new Nova Pitching wedge (48 degrees). A perfect fit and I'm very pleased.
I recently purchased a set of Blackstone one‑length irons from a local golf shop, and even though I bought the demo set, the quality has been nothing short of outstanding.The heads, shafts, and grips all feel solid and well‑built, with the kind of confidence‑inspiring look and feel you expect from a premium set of clubs.
What has impressed me the most is how easy it is to move from one club to the next without having to think about setup changes or make constant adjustments.Because every iron is the same length, my stance, posture, and ball position stay the same, and my swing feels repeatable throughout the bag. The result was almost immediate: my strike consistency improved right away, and my contact now feels much more solid and predictable from club to club.
If you’re curious about single‑length irons or have struggled with consistency, I highly recommend giving these Blackstone clubs a try.
