Pinhawk SL Single Length irons are designed to promote consistency via a single head weight and single club length. The club heads are USGA Legal and are intended for all handicaps.

Pinhawk SL Single Length Irons Bottom Line

I have been using a set of Pinhawk SL single length irons for over a year and have seen my scores decrease from the low 100s to the high 80s, primarily due to the increased accuracy of my irons (although there are other factors that you can read about in my single length irons journey).

I often play with random people when my regular playing partners are unavailable. I never bring up the subject first, but in every single case, I’m asked about what irons I’m playing after a few holes. Most people have heard about single length irons, but didn’t really understand the concept or believe that they would work on the golf course. It usually only takes a few minutes to explain, but what really convinces them is the accuracy of my iron game.

Who are these clubs for?

These clubs are great for both beginners and experienced golfers since the underlying idea behind single length clubs is to reduce the complexity of the game which makes golf more fun for everyone — even your friends and that group behind yours that appreciates not having to wait for you to find your ball every other hole.

You can also expand your set with Pinhawk single length wedges and Pinhawk single length fairway woods:

Look & Feel

The overall look of the clubs suits my eyes and I especially like the club number engraved on the face of the club for those last minute checks as you’re looking down at the ball preparing for the next critical shot into the green with skins on the line!

The face of the clubs has a unique checkerboard design that interrupts the grooves. Not sure what the purpose of this design feature is, but it reminds me of the Purina brand (which always makes me think of my dogs growing up — not a bad mellow thought to have during a round).

As far as feel when striking the ball, you can definitely tell when you’ve hit the ball out of the center of the face vs. the heel or toe. A center-struck ball produces absolutely zero feedback — no jarring, or vibration at all — it almost feels like you completely missed the ball altogether.

The design from club head to club head does not vary greatly, but the “channel” behind the head does narrow as you go from P thru 4 iron by 2.5 mm (from 8.75 mm to 6.25mm).

Price

Pinhawk SL iron heads are extremely affordable, coming in at less than $19 per head. This price point is well below the rest of the single length irons market, and allows you to build a 5 thru PW set for around $250 (most drivers cost more than that these days).

You can see the price points of all manufacturers’ single length sets in my Single Length Buyers Guide.

Hybrid Options Available

Pinhawk also has hybrid heads available from 4 thru SW for those golfers who prefer hybrids over irons. You could also mix & match the heads, like a set with 4 & 5 hybrid heads and 6 thru PW iron heads.

The hybrids do cost a bit more than the iron heads, but you can still build an entire set of 5 thru PW hybrid clubs for around $325.

Accuracy vs. Descent Angle

The trade-off given for increased accuracy is of course a shallower descent angle of the ball as it falls from the sky. This trade-off means that on the 4, 5, and 6 irons’ stronger loft leads to more roll-out when the ball lands on the green.

Personally, I’m perfectly OK with the roll-out since I’m happy to have the long irons hit the green more often in the first place.

Gaps

The gaps in the set are fairly consistent between 10 and 15 yards from club to club. On the day that I recorded the data below, I hit some very good 4 and 5 iron shots, which were 10 to 15 yards longer than what I normally hit.

Here are some of my “solidly struck” shots using the Pinhawk SL clubs:

Club 4 5 6 7 8* 9 PW

Apex 37.4 25.7 33.6 29.2 39.6 37.4 37.8

Technical Specifications

The iron heads have a weight of 272 grams and the complete irons have a weight of 450 grams with a +/- 2 gram variance. I used True Temper Dynamic Gold S300 130g stiff shafts cut to 37.5″ with a D8 swing weight.

As you can see in the tables below, the Pinhawk SL lofts are stronger than a typical set of irons from club to club, which is necessary given the single length shafts — longer shafts hit balls farther, so with a shorter shaft, a stronger loft is necessary to hit the ball the same distance.
