Meet your new favorite putter - the 1 Iron Big-O Putter! After years of research and testing we are proud to offer the ultimate putter in the golf industry. Designed with extreme counterbalancing, our face balanced putter head is heavier than standard for the highest level of clubhead stability and consistency throughout the stroke. The clubhead is then counterbalanced with a heavier grip than a standard putter so that the center of gravity is moved closer to the player’s hands which promotes the larger muscles of the shoulders in making a pure and smooth pendulum putting stroke for pro-level putting. Our Big-O Putter is not method specific and will drastically improve your putting regardless of your preferred putting method.
To optimize your stroke stability through proper counterbalancing you will want to measure your current putter and then order the next size upBig-O Putter. The extra club length should extend beyond your wrists when you grip the club to ensure optimum counterbalancing. Read more about the 1 Iron Big-O Putter!

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 (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.

Big ole putter
Well I tried out the putter today and all I can say is wow,everything felt weighted right and I sunk a lot of putts especially my short putts I was having problems with,whoever uses this putter will cut 6 or more strokes off of there game I’m just mad I didn’t do it sooner smh best putter I’ve ever used…
Kevin H. (Lawrenceburg, US)
Gonna try out this putter Tomm but using my putting mat I love they way it feels with the counter balancing and coming off the face definitely better than my Spider putter,y’all nailed it with this putter Thanks,another review to come after I play!!!
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!!
