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. Old fashioned club numbering has been replaced by the actual loft angles for precise club selection and distance control. 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 6 or 8 Iron Sets only. 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: Installed with oversized grips.
  • 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) 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.

It's the Indian AND the Arrows

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.

Thank you - you've earned a life long customer.

Love My New Irons

I am loving my new Blackstone Irons. Already, I am getting more consistency with every swing. I'll be looking into get some new Woods in the near future!

Nick C.
I’m happy as can be!

So I started playing in the spring of 2021…. I become obsessed with stuff when I get interested. I have had 3 major back surgeries so I wanted same length irons and extra tall clubs because I struggle to bend at the waist or turn my hips. I’m 6’4 and wanted extra long clubs. I stumbled onto 1 Iron and I’m glad I did. I bought the full line of Blackstone, all the wedges, the Driver and putter as ling as I could get them. I’m dropping strokes the more and more I become comfortable the better I’ve become.

May not seem like a lot to more experienced players but I shot a 43 today on 9. I had a terrible first hole and rimmed 3 putts. I realistically could of had a 40. I had a 290yd Drive. I’ve only been playing for 15 months. I’ve had my 1 Irons since Christmas and live in the Midwest so I didn’t start using them until April, three months ago.

I highly recommend!

I play 3-4 times a week and the pic of the clubs is after about 25 rounds.

First weeks with new irons

I am very pleased with my new 1 iron golf iron set! I’m hitting the ball straighter and more consistently right off the bat! And their customer service has been spot on! Had a small issue, and they took care of it right away! I would recommend these clubs to anyone looking for a change!

Trae F. (Sun City, US)
Blackstone Irons

I've had my Blackstone irons for approximately 3 weeks now and I'm loving my purchase and couldn't be happier. Having the club's custom fit to my wrist to floor measurement has made all of the difference. I've been able to groove my swing and are hitting my irons crisply. The most challenging part has been the wedges, but with practice, each day I get more consistent in hitting them. Thanks David for a great product and I appreciate all of the articles and information you have on the website. I researched and read everything before my purchase and the tips you have provided on your website are extremely valuable. Thanks again.
