Pinhawk SL Single Length Iron Heads

  • The newest and hottest trend in golf is single-length irons!
  • Looking for more consistency from your iron game? The new Pinhawk SL Single Length irons are extremely popular for a reason. Contrary to a traditional set of irons, the SL's are all designed to be the same length throughout the entire set. In addition, the swingweight and flex are also the same. This allows the golfer to use the same swing, on the same plane, with the same feel, for each iron in the set.
  • The loft gapping is slightly larger than traditional irons; this is to maintain a proper distance gap between clubs. The suggested men's length for the Pinhawk SL's is 37", which is a typical 7 iron length.
  • The same length design allows to have the same stance, same posture and the exact swing plane for every shot regardless of iron number. These are the factors that allow you to only need just that one swing no matter what shot you are taking. Golf got easier now. If you are looking for consistence in your iron game, single-length is the way to go.
  • Assembly Instruction for Single Length Irons: These irons are assembled differently because the head weights stay the same throughout the set. Tip trim the shaft for all heads if it were a #7-iron, regardless if the head is a #4, #9 or SW, i.e. do not tip trim shafts in increments. Cut the butt end to length for all clubs in the set as if were a 7-iron. If someone orders a set +1/2", then make that length ½" over your standard #7-iron length for all clubs.

Pinhawk SL irons are an excellent choice if you want to play single length. Very good quality club head.

Advantages: Consistency of strike!

Very nicely constructed heads. I built 5-AW left-handed set. I'm 6'4" so I added 1.5" to my standard 7 iron length. I'm an 85-90 golfer so I'm looking for a little more consistency and these seem like they will help. I have only played once so its a matter of learning distances but the ball comes off the head really well on good struck balls with plenty of spin. These clubs are definitely for people looking to get the ball airborne as they are weak lofted so you may have to club down which isn't an issue for me. As for my round I shot an 82 and all the well struck irons were straight as an arrow towards the flag with the only issue being they were coming up about 10 yards shorter than my Ping G10s but I like the consistency & will just dial in these clubs for distance.

Advantages: Well made, High launch, Really good spin, Accuracy, Workability,

Disadvantages: Weak lofted so people who like to brag on iron distance may not like them

Just received the heads, 6 thru Aw. Asked for 1* upright and they are marked as such. Weights are NOT consistent. In grams: 273, 273, 269, 270, 272, 273. I guess I should have requested a hand-pick. My shafts are all within one gram of each other. Will need to use tip-weight in order to equalize swing weight. Dry-fitted everything and think I have it figured out. More consistent head weight would have been easier! Heads look DO look nice and am anxious to build and play. Will be a few weeks yet before that is possible. Will give a "playing" review when possible.

Great iron heads. Well made. Perform great. Built my first set of clubs using Pinhawk single length iron heads, Apollo Acculite 95 shafts, Sting Stoppers and Golf Pride MCC4 reduced taper grips. I was designing for accuracy and consistency and not distance. Design intent achieved. I have played these for nearly 2 months now and they are terrific. Great ball flight. Consistent and accurate. Feels good off the club. No issue elevating the ball from 4 iron on up. I do have a very vertical single plane swing which helps with ball launch. Hitting the P, AW, and LW well.

Advantages: Quality, great feel, good elevation off the club face

Disadvantages: The polished part of the heads, including the bases, seem to scuff and scratch quite a bit. No issue with performance or from what I can see longevity - just looks a bit scratchy.

I bought the 5 Iron head to complete my wife's set. She is 76 and does very well with these irons. A great solution for older golfers.

Advantages: Single set up, single swing,

Disadvantages: none
