We custom build all orders, please allow 5-7 business days for your order to ship.
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.
Custom Built: Custom built single-length irons fitted based upon your wrist-to-floor measurement. Each set includes headcovers and distance clips. 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.
Experience: Enjoy greater consistency with a custom built set of single length irons and woods. Being in business for over 20 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.
Taking your Wrist-to-Floor Measurement:
The wrist-to-floor measurement should be taken while standing on a hard surface.
Wear jogging/gym shoes or street 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
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.

We warrant our golf clubs to be free of defects in material and workmanship for a period of one year following the original ship date. We will, without charge to the original purchaser, repair or replace the club if it proves to be defective during normal use within this period (normal use does not include misuse or abuse and the associated damages ie: dents on the top, side, rear, or sole of a wood club-head). This does not cover grip or cosmetic wear and tear due to normal usage. Any alterations to the original golf club voids this warranty.
