Pinhawk Vertex Dual Length Iron Heads

The Pinhawk Vertex Dual Length irons are the ultimate in modern day technology for game improvement. The golf industry has learned a lot in the last few years with regard to irons. Single length irons, whether it be our own extremely popular Pinhawk SL irons, Cobra’s, or other brands, have been proven to make the game easier. Bryson Dechambeau, love him or hate him, has shown the world that the single length concept is viable even at the highest level.

But is a full set of single length irons, from 3 iron all the way through sand wedge, ideal for every golfer? Simply put, no. A player with a slower swing speed may have trouble elevating their “long” irons in a single length set. If they do not have the swing speed in order to achieve an adequate launch, it can sap the distance of their “long” irons. Of course, for many, dealing with a lower launch on their “long” irons in single length clubs is worth the trade off of having game improvement consistency.

However, for many of us, we want our cake and we want to eat it, too. Introducing the Pinhawk Vertex Dual Length Irons! A vertex in math is defined as “a point where two lines meet”, and that is the perfect name to describe these irons. They combine the best of both worlds for the ultimate in consistency: Not completely single length, and not traditional length. Instead, just two different lengths: the 3, 4 and 5 irons one length, and the 6, 7, 8, 9, PW, AW, SW another. This configuration results in no distance loss in the long irons and the full benefits of single length irons in the “short” set (6-SW). 2 different lengths, and just 2 swing planes, vs many planes in a traditional set.

Frequently Asked Questions:

How long are the long irons and how short are the short irons?

The long irons are a standard length of 38” (a standard length 5 iron in a traditional set). The short irons are a standard length of 36 ½” (a standard length 8 iron in a traditional set). 2 lengths, just 2 swings, no elevation issues.

I’m short (or I’m tall); can I get a different length?
Our standard length is generally the “sweet spot” for most players. If you are exceptionally tall or short however, standard length may not be for you. We are able to vary the lengths up to ½” either way easily. In exceptional cases, you can email us for recommendations for much longer or shorter sets and we will tell you if it’s possible. Look at our WTF (wrist-to-floor) chart below for general recommendations. For more details on how to measure your wrist-to-floor, look under “Club Length” of our fitting page.

Can I just order the “short set”?

Absolutely. As we mentioned above, the “short” set (6, 7, 8, 9, PW, AW, SW) is a no-brainer for almost any golfer that wants more consistency in his game. We honestly feel that you would love the entire set, but we realize that some players don’t use irons much beyond their 6 iron.

Why do the 3 iron and the 6 iron look slightly different than the rest of the set, and why do they cost more?

The 3 and 6 iron use a new iron technology. First, they have an ultra thin, high strength cup face to help increase ball speed and maximize distance. The weight saved by the thinner face is positioned to allow for an optimal launch angle. This is a hollow bodied design that provides unparalleled forgiveness and distance. Hence, it costs more.

The technology used in the lower lofted club in each of the two Vertex lengths (the 3 iron being the lowest lofted club of the long irons, and the 6 iron being the lowest lofted club of the short irons) is necessary for correct distance gapping across the entire set.

Tell me again why the #3 and #6 were designed the way they were?

They are the irons in their respective length group that needed “extra” launch and distance to achieve proper gapping because they are the lowest lofted clubs in their length grouping. Remember, the lower the loft, the higher the difficulty to launch the ball correctly. The hollow bodied, thin face design of these 2 clubs make up the difference needed. Testing confirmed that the extra technology was needed in these 2 irons.

Has this ever been done before?

Sort of, but modern technology has made it more viable. Even as far back as the Bobby Jones era, club manufacturers knew that fewer lengths in a full set of clubs helped the golfer establish more consistent swings. Bobby Jones himself designed a set of Spalding clubs called Kro-Flite which featured some irons in the set at the same length. We were so intrigued by this that we found a set on eBay that is hanging up in our shop!

Here’s a picture of the ad that Spaulding used. Obviously in the 1930’s they were limited in what they could manufacture, but Spaulding and Bobby Jones knew that the less “swings” in a set of irons, the better.

Another niche company, Simpletons, also produced a set of dual length irons, but didn’t have the technology in their set that the Pinhawk Vertex has, and didn’t have sufficient success with their marketing efforts to gain any traction. But was the idea sound? Yes!

Do they come in Left Handed?

No. We don’t have plans for left handed at the moment, but as with the Pinhawk SL irons, the popularity eventually necessitated it, so you never know.

What are the lofts?

Lofts, lies, weight of the heads, offset, bounce and hosel depth can be seen below:

Club	3	4	5	6	7	8	9	PW	AW	SW
Loft	18.5°	22°	26°	28.5°	31.5°	35.5°	40°	45°	50°	55°

What kind of steel are the heads made of?

431 Stainless Steel Body, Hi-Cor 17-4 Stainless Steel faces.

Can’t I just buy some other iron heads and make a set like this?

No single length or dual length set of irons can be made from traditional iron heads. A traditional set of iron heads has a different weight for every head. If you were to try and build a set of single length or dual length with heads of varying weight, not only would your swing weights vary wildly, but the flex of each club would also be different throughout the entire set.

Can they be bent for lie?

Yes, they can be bent upright or flat a maximum of two degrees.

What is the recommended tip trimming and club lengths for building Vertex irons?

If you are building according to a tip trim chart, tip the 3, 4 and 5 irons to a typical 5 iron tip trim, and tip trim the 6, 7, 8, 9, PW, AW, SW irons to a typical 8 iron tip trim.

The recommended standard lengths of the 3, 4 and 5 irons is 38” and the recommended standard lengths of the 6, 7, 8, 9, PW, AW, SW irons is 36 ½”.

Are They USGA Legal?

Yes. They are listed as conforming irons on the USGA Informational Club Database, listed under Pinhawk, right after Ping.
