Our premier line of irons are without a doubt the most advanced set of single-length irons in the golf industry. Our iron lines are not built for any particular handicap, age, or skill level. Capitalize on precision and accurate shot making with the Blackstones. Proper clubface alignment at address is everything 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 makes club-face alignment exact and automatic at address. With a set of Blackstones you will find a lot more birdies on the golf course. Check out our Irons page for more details.

  • Custom Built: Custom built single-length irons fitted based upon your wrist-to-floor measurement. All Blackstone Irons come with head covers. Distance clips are included in Blackstone Irons Sets. Conforms with the Rules of Golf and built in the USA by Master Club Builders.
  • Shaft: Shafted with our proprietary Black Steel shafts for zero glare and extreme tour performance with shaft flex plane orientation (Spine Align/Puring), and identical shaft flex throughout the set.
  • Clubhead: Loft angles instead of club numbering for precise distance control with bright white scoring lines for precise clubface alignment at address. State of the art precision face and sole grinding. The deep undercut rear cavity produces a low center of gravity for maximum trajectory and distance with identical swing-weight and moment of inertia (MOI) throughout the set.
  • Grips: We only install our proprietary 1/8” oversize grips on our golf clubs which are produced exclusively for us by Lamkin.
  • Finish: Black PVD (Physical Vapor Deposition) finish for zero glare at address. PVD finish produces a harder surface for extra ball compression and greater distance. Bright white scoring lines for precise clubface alignment at address.
  • Experience: Enjoy greater consistency with a custom built set of single length irons and woods. Being in business for over 25 years we have perfected single length play. Ditch convention for common sense.

Custom Fitting Single Length Irons

All human beings share the same skeletal, muscle, tendon, and joint functions and from a mechanical standpoint are the same regardless of height or sex. Non-mechanical differences arise in custom fitting however, for instance: the height of a bicycle seat needs to be greater for a taller person than a shorter person even though the mechanical design of the bicycle remains the same. By the same token there is only one true fitting variable in the building of golf clubs and that is club length. Based upon your wrist-to-floor measurement we adjust your club length to correspond to the lie angle of our club-heads in order to ensure a proper fitting.

Wrist-to-Floor Measurement
Taking your Wrist-to-Floor Measurement:
  • The wrist-to-floor measurement should be taken while standing on a hard surface.
  • Wear jogging/gym shoes (not golf shoes).
  • Stand with your back against the wall at strict military attention. Place your shoulders and head against the wall, your feet together, and your arms rigid and straight down at your sides.
  • Hold a pencil in your right hand (right handed golfer). Back your arms against the wall and then take the pencil and make a mark where your left wrist joint hits the wall. Just the opposite for a left-handed golfer.
  • Measure from this mark to the floor.
  • Important: Do not round-up the measurement to the next higher inch increment. For instance, if your measurement is 34 and 7/8″, do not round up to 35″.

One Iron Golf Club Lengths

One Iron Golf Club Lengths - Wrist to Floor Measurements

Very Important:

Do not order based upon what you consider to be your favorite iron (ie: #7 iron), and do not use that corresponding wrist-to-floor measurement when placing your order. When ordering you need to specify your actual wrist-to-floor measurement to ensure a proper fitting. This chart reflects club length based upon our club-head lie angles. Consequently, our fitting process does not apply to any other brand.

For the taller golfer:  based upon your wrist-to-floor measurement you may be concerned that your irons would be a typical #3 or #4 iron club length; however, do not compare your measurement to your current #3 or #4 iron. The lie angles of your “long” irons are much flatter than ours which, at your size, requires you to bend over excessively and reach out for the ball at address. The club head lie angle of our irons is 63.5º which is far more upright and allows you, for the first time, to stand upright and much closer to the ball at address resulting in the ideal upright swing posture and swing plane. The taller golfer benefits the most from our fitting formula since they have never played golf clubs that have even come close to fitting them properly. The result being that they have had to develop a very inefficient posture and swing where they are bent over excessively and reaching way out for the ball with every iron in the bag.

How Does the Wrist-to-Floor Measurement Work?

It is based upon trigonometry. At the point of ball impact in the downswing, your wrist, the ground, and the club-head, form a right triangle. Assuming an ideal swing posture, there is a non-linear mathematical relationship between your wrist-to-floor measurement while standing at attention and your wrist-to-ground distance at ball impact.

The club-head lie angles are known for the irons and fairway woods as well as the length of one side of the right triangle based upon your mathematically factored wrist-to-ground distance at impact. This gives us the measurement of two angles and the length of one side. We then use trigonometry to solve for the hypotenuse or club length. This is somewhat oversimplified as we factor in shaft deflection and numerous other factors. The fitting formula that we developed produces the ideal golf club length for anyone regardless of height or arm length.

Return Policy

Fully try-out our golf clubs at your home course and at your convenience for a full month. We feel that to truly evaluate a set of golf clubs to determine if they are right for you takes time; and hence, our 30-day return policy (does not include Used/Demo golf clubs, Accessories, or Special Orders). To our knowledge we are the only golf club manufacturer in the entire industry who offers a full money-back return policy on golf clubs after they have been played which should tell you volumes about our commitment to our customers.

A return authorization must be obtained before we can accept a return of merchandise. Contact us for this authorization on-line through the Contact page of this website. Shipping/handling charges are not refundable. All contents listed on the original Packing Slip must be included for a full refund. Return shipping charges are the responsibility of the customer. Our return policy is only valid once per customer. Any alterations to the original golf club voids this policy.

If shipping from outside the USA make sure to show that the country of origin is the USA and is a return of USA manufactured goods on the customs form. Also, be sure to make clear that you (the shipper) are responsible for all shipping charges and any brokerage/storage/handling/duties and taxes incurred. We will not accept any return package where a payment is due - the shipment will be returned to you at your cost.

New Irons

Bought these to see if it could sort out my wedge game as when I crouched too much I was coming in thin and or early.
Have not had time to adjust on a range but first few rounds very positive. Weight of and feel of irons are great. Hit well instantly. Once I break posture habit should be good. Love the large face and the 55 degree was great out of some less than nice traps in Caribbean. Want to get to my summer course where there is an excellent range. I would give these irons an 8 out of 10 with my posture to blame for not perfect mark.

One Iron Golf supports their clubs!

Changed my game

I was making do with my pitching wedge and not really nailing it from short range. The lob wedge was just what I was missing. After 2 seasons with my Blackstone full set, it immediately became another consistent club in my bag. Glad i added it.

Same great quality as all the One Iron clubs.

First set of New Irons

These Blackstones are my first set of new irons. They play just as well as any other brand. The black finish is already starting to fade from the club heads after 10 rounds. Great set for a beginner to average player. I would recommend a different set for advanced players. These will last me for this season but I see new irons for next year already.

No number on club just degrees

Need to add the club Numbers the people I showed it to did not like the degrees without the numbers . I would not bought them if I knew there were no club numbers on them

Hi Samuel, we are sorry for the confusion. We prominently display the degrees in our photos of the Blackstones and list it as a specification in the description of the Blackstones so that customers are aware. I know another customer liked seeing a number and so he bought a headcover with a number, that is a good option. If you are interested in why we decided to forgo traditional numbering, our designer/founder, David Lake, replaced the iron numbering system with the actual clubface loft angle for pro-tour level precise distance control. You can refer to one of his earlier Newsletters that addresses this in complete detail: The Truth about Loft Angles under the Golf Tips menu - https://one-iron-golf.myshopify.com/pages/the-truth-about-golf-club-loft-angles. Thanks again for your purchase!

My new golf iron 1

Thanks so much David.

I'm stagered

I'm 52. When I was 23 up to 25, I was shooting under 80.

I seriously returned to my golf 6 months ago, playing at least two times a week, and I used to play with the AP2 Titleist golf set, but I was not able to bring the score below 90, I've played four rounds since I received my new Blackstone clubs, I've shot an 81 and 84 and an 85 I'm the happiest guy at least in Mexico.

Best regards and thanks for your help.

Golf simplified

As a weekend golfer getting frustrated with the inconsistency of my swing, I bought these clubs without ever trying them and adopted a single plane swing. A few range sessions led to straight and consistent ball striking, my typical slice gone. The clubs are forgiving and a bad swing still produces a playable shot. One length, one setup, one swing…golf simplified.
