770CFE Computer Face Engineered Irons

Discontinued Model

Variable Thickness, CNC Machined Forged Face Design Increases COR and Delivers Better Off-Center Hit Performance


  • The 770CFE irons represent the first set of irons designed with a ultra-thin, forged high strength steel, CNC machined, variable thickness face design.
  • The 770CFE irons are designed with a thin, variable thickness forged face to deliver a higher COR for much more distance than is possible with a conventional thick face iron design, but also to offer golfers a much better off-center hit forgiveness because of the variable thickness face design.
  • Because irons increase in loft progressively through the set, the actual force of deflection of the face will decrease as loft increases. To help maximize the amount of face deflection as loft increases in the irons, the forged variable thickness face design changes in steel alloy composition and thickness. The #3 through 7-iron faces are forged from Carpenter 455 high strength steel, designed with a variable thickness of 2.4mm/1.9mm.  The #8 through wedge faces are forged from 17-7 stainless steel and machined to a variable thickness of 2.6mm/2.2mm.
  • In addition, as loft increases in a set of irons, the actual position of impact on the face will change. To accommodate this slight change in iron face impact position, the thicker center section of the faces also changes in position on each 770CFE iron through the set to match.
  • The 770CFE irons were individually computer modeled for face thickness dimension, face thickness position, and face material for each iron in the set to offer the best individual performance possible in a full set of irons.
  • All 770CFE faces are CNC machined after forging to ensure precision in the face design. The CNC machining marks can be seen on the back of each face.
  • The sole design of the 770CFE is designed to keep a large amount of mass low, but by beveling the back edge of the sole the sole width is not so wide to ensure proper sole playability from all types of turf and lie conditions.
  • 770CFE irons are finished in a bright satin polish finish, with all faces CNC machined for precision dimensional specifications.
  • Available in both RH and LH versions.  RH in #3 – 9, PW, AW, SW.  LH in #4 – 9, PW.
  • 770CFE irons are produced with post-2010 new USGA scorelines.


  • 770CFE irons were awarded the Golf Tips Magazine’s Top Concept Tech Award for 2005.

  1. Mr. Wishon there’s not any chance that you have single clubs available for purchase? I have a beautiful set of the 771 CFE and I am missing the 7/8 iron and s/w a/w I sure would love to complete the set for my bag. Please let me know if by any chance you have these clubs available for purchase

      In your message you referred to the 770CFE and the 771CFE. If you are in fact asking about the 770CFE, this model was introduced in 2004 and was discontinued quite a number of years ago to make room for the newer 771CSI irons, which we still offer to clubmakers for custom building. If you do mean the 770CFE, I am afraid the only place you have a chance to try to find a 7 and 8 iron would be to search on Ebay. Beyond that you can google the Association of GOlf CLubfitting professionals, head to their website and send them a contact email to ask the administrator if he could put a post on their private member forum to ask the member clubmakers if any of them have a left over or used 770CFE #7 and 8 iron – and leave your contact information with the admin so if anyone did have one they could contact you.

      If instead you mean the 771CSI irons, if you are a clubmaker yourself you could buy the heads and any shafts you may need from Diamond Golf International who are the current distributors of my product line since I am semi retired now. They are in the UK but they do have shipping deals for US and Canadian clubmakers. You could contact them toll free at 844-552-3437 or by email at sales@diamondgolf.co.uk. If you call, remember they are in the UK. If you are not a clubmaker and in search of a 771CSI #7 and 8 iron, you can contact a custom clubmaker who works with my designs to have him obtain the heads and build the replacement irons for your set. To find a clubmaker you can head to our HOME PAGE and on the top of the page click on the link for FIND A CLUBFITTER. Enter your location and the clubmakers closest to where you are will be displayed with their contact information.

      I hope this helps and wish you the best in your search if this is the older 770CFE model,

  2. I still can’t find a better iron than the early 1990s CMC 5000. The latest losers for a spot in my bag are Ping iBlades.

      How about that! I was just looking at the one set of CNC5000s that I have left over from those days many moons ago. Brought back from fun memories as it was the first and I think only full set of irons made with milled faces on each head. Thanks very much for stopping by and sharing your experience with one of my early designs ! Best to you in this great game as well,

    • Yes, the milling grooves are still pretty prominent on my irons and I’ve used them for almost 30 years (not exactly sure when I put them together). They’ve served me well.
