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 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. Click here for all our Blackstone Line offerings.

    • Custom Built: Used/Demo Irons are STILL custom built to ensure they are in excellent condition. 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.
    • 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.
    • 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.
    • Grips: Installed with oversized grips
    • 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) 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

    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.

    Great buy, worth every penny!!
    Top quality used clubs offer was really the opportunity I was looking for to jump the fence and try one lenght. Not going back to traditional clubs anytime soon:

    Starting to figure them out

    I purchased the 27° Thru 47° clubs (6-Gap) I kept my wedges because I did not want to play with longer wedges my goal was to make my iron‘s shorter.

    It did take me a while to get used to my pitch shots under 100 yards But I’m really starting to score now from that distance.

    Starting to get more distance on my “six iron”. Just need to convince my to use the same ball position.

    Although I’m not hitting them as long as I would like to. My Misses leave me in a better position to get up and down.

    I use the Arccos golf system so I get a pretty good read on what I’m actually doing. I’m confident it’ll just be a matter of time before I get the results I want.

    I purchased a Demo set. They were in great condition.

    ONE Blackstone Iron golf

    I have been out on the course 4 times with my new Blackstone Irons.. Initially, I was chunking my hits quite a few times trying to find the revised pattern swing required for the irons .....but by the fourth-round consistency came into play. I was hitting the balls down the middle of the Fairway on a consistent basis. A major Improvement in my game! The only issue I found, being a six-foot-three muscular character I found the irons to be slightly too light. Ideally, the mass of the heads should be a few Oz heavier. But on the positive side, I've seen a major Improvement in my golf and my golfing experience. Very pleased with the purchase.

    The chat room was very helpful An being able to purchase one of your demo sets helped the sale drastically !! Thank you

    High-speed player detailed review

    I purchased a full set of demo/used Blackstones, 3-LW and took them on vacation with me recently. Some info about me: I’m 6’3 and swing a driver around 112 mph with ball speeds around 160, though I can at times put it out farther when all is clicking. I have been playing Taylormade P790 with X100 Tour Issue shafts the last 3 seasons. Love my 6i and 8i, hate my 5i and 7i and regularly miss the green from easy spots with my PW and 9i thanks to pulled shots. I live in NE WI and the weather in the winter is brutal. I had been planning a full-bag renovation at Club Champion, but thinking about my game and reading about these clubs, it just made too much sense to my engineer brain…but I had some questions. Questions a trip to Aruba would answer over the course of a week of absolutely fascinating golf learning.

    Question 1: they are cast…how do they feel?

    Question 2: will the shafts hold up to my speed and sometimes violent transition? Would the spin be way too high…especially in constant 20-30+mph winds from the east on coastal links?

    Question 3: what would really, really long sand and lob wedges be like?

    The reality is that the feel of a shot hit on the screws is very, very pleasant with these clubs. I hit 4 and 5 irons on the button a number of times…after bunting one into the long stuff, pulling a couple and hitting them way shorter than I thought I should a few times. But on hole 6, after a snapped drive into the wind, I sizzled a 4i onto the green from 180 into the gale. I was dumbstruck how good that shot felt; how far it went into the wind and how it was sitting next to the stick when I got up there.

    I had absolutely zero trouble with shots ballooning; only a couple short iron shots ran away from me down wind and I could accurately club up or down for what I was facing.

    Lastly, after having some really good and really bad results with the 55 and 59, I have come sprinting back to my wedges. I am going to play the 51 for a while because it is so good on full shots, but my vokeys were back in the bag as soon as I got home. Some of it is that I haven’t had time to practice with these and the ball positions you need to play partial shots around the green, but a smaller swing radius makes more sense to me.

    I played two rounds and had three range sessions with the wind straight in my face at Tierra Del Sol and have figured out how to hit several different shots with the Blackstones, but mostly they go were you point them…which for a 15.6 that longs for his days under 10, is a miracle.

    I’ve built clubs and have done my own shafting, regripping, loft/lie bending etc for friends and family and am a huge believer in spine aligning clubs the way 1irongolf does. It makes a difference.

    This is a wonderful concept and is very well executed. My P790s are on the trading block on Golfwrx as I write this. I did notice the black finish come off the shaft of the LW after a massive lash through some underbrush on a downwind par3 where I should have clubbed down a club or two more because of how pure and high I hit it and the rocky terrain left a number of silvery scratches on the soles and leading edges of several of the clubs…things you don’t see with a standard finish…but these things are good…really good.

    Thanks for making a unique and outstanding product.

    Black stone irons

    Very much like my clubs, I hit them more solid, higher trajectory, and with more accuracy. Very happy.

    Todd K. (Springboro, US)

    I’m still loosening up from the winter and dialing them in. So far so good. I love the look and feel.

    David R. (Oconomowoc, US)
    Blackstones replace original “cavity backs” 40yrs old. Awesome.

    Found clubs packaged nicely and in excellent condition for a “demo set”. Looking forward to striking that first ball. They set up beautiful. Previous iron set served me well, 40yrs old, with a similar black look minus the great white outline. Like the feel. Photos to my two sons sent advising they are next! Thanks David for staying the “course” ;).

    Blackstone demo

    I bought a blackstone demo set 29* to 51*. The demo set was in great shape, almost new. I love these irons. Extra easy to hit and felt great in my large hands.
