Precision Tooling, Shaft Balancing, and Club Stability for the ultimate in Precise Shot Making. Modeled after touring irons, maximize your distance without compromising accuracy.
Custom Built: Custom fitted based upon your wrist-to-floor measurement (see below for measurement instructions). Identical club length, clubhead lie angle, swing-weight and (MOI), and shaft flex throughout the set.
Clubheads: Tour proven clubhead design. 2º stronger loft angles throughout the set for increased distance. Lighter clubhead weight for increased swing speed and distance. Deep undercut rear cavity produces and extremely low COG for maximum trajectory and distance. State of the art precision casting, grinding, and polishing. Latest groove technology for maximum back-spin.
Shafts:Steel shafted for the highest level of consistency/accuracy. Shaft flex plane orientation (Spine Align/Puring). Optimized shaft tip section for extreme stability through impact and tighter shot dispersion.
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.
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) not in excess of 1.5" sole.
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
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.

Pro-Line irons hard to launch
Purchased the irons and had trouble hitting them after numerous trips to the driving range.. The clubs look great, but the grips are hard and I had trouble launching them very high compared to my old Cleveland irons. I had high hopes for these irons but decided to return them.
Mike C. (Indianapolis, US)
Absolutely love my irons.
Bryan H. (New Orleans, US)
I love my irons, one simple swing , I'm shooting in the 70's more often now. It's hard to break 80.
Ken W. (Torrance, US)
Totally satisfied customer 😀
I've played 5 rounds with my pro-line irons, and I'm totally pleased with them. I love the feel of these irons. I've been playing golf for 30 years and have owned 7 sets of irons, and these pro-lines are by far the best. I purchased the 3 thru PW, and I'm going to order the SW, GW and LW. These irons feel like butter, and the distance that I'm getting is amazing. I wish that I would have gotten these irons years ago!
Daniel K. (Boerne, US)
Took these to the driving range one day - hit about 80 balls. And played one round with them. Overall, I feel the difference in ball-strike. However, I feel the lie may need a minor adjustment. Want to hit another bucket of balls before making final determination.
Joel J. (Calabash, US)
Want to hit it straight?
Took me awhile to get used to them. But after I learned how to properly swing, they go straighter than any iron I’ve owned.
Michael F. (Schertz, US)
Great clubs and amazing service
David and his team do an amazing job and their one length clubs are the best in the business!
David B. (Melbourne, AU)
I am very happy with this purchase , and it was good to be able to use the club with ease. Being the same style as the others , there was No "dialing in"
It just worked , beautifully.

1Iron Golf are great Cubs
Purchased my 1iron Pro Line clubs a few years back. Only wish I had bought them sooner. Having one swing plane and set up for every club makes golf much easier.
As golfers, we've all heard the expression, "it's not the arrows, it's the Indian." The suggestion in 'golf-speak' is that great equipment can't fix a poor player. However - I can say without question or equivocation, that for a "pretty good player" (like me), great equipment can absolutely make a difference.
The Blackstone One Iron clubs are simply put, the very best irons I have ever hit. I've tried many different models (both in variable and single length styles) and there simply isn't a club out there that is as easy to hit as consistently and whose contact feels as solid as the Blackstones. They feel so dang good.
If you're new to the single length concept, don't fret over the fear that your short clubs will be too long or vice versa - gapping is precise (for me, about 8 yards carry in between each club).
And if you're already a single length player (as I'd been for 9 months before I bought my Blackstones), you simply won't find build quality and ease of strike better than these. HIGHLY Recommend.
A last word on customer service. When my clubs were delivered, there'd been a SNAFU on the grips. David Lake took care of it immediately.
Got my new Blackstones one week ago. Still getting used to them but I'm hitting the ball way better with thses clubs. Straight crisp shots. The biggest difference is I dont have to worry about my stance and posture anymore. That alone is huge for me. Most likely the last set i'll need to buy. Clubs shipped in 7 days great service.
Pretty excited when they arrived, I won’t lie. Bought a full set of the demo irons. I’ve played with them 3 times now since having them for a couple weeks. Already hitting much better. Honestly, I haven’t used my long irons for years because I just couldn’t hit them worth a hoot.
Been hitting these pretty good. My approach shots have been straighter as well. Still have to work on distance, lol, but the are straighter. Had an issue with one of the clubs while playing and I sent an email while I was on the course. The owner actually answered me back right away and had a new club being sent FedEx to me the following Monday.
To make the point more valid, the set I purchased was as is with no warranty, but they never blinked. Sent me the new club right away. Love the clubs and love the customer service. In a day and age where customer service is lacking in many industries, these guys get it! Thanks One Iron Golf!!
