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.

    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

    SHEA 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… Read more »

    Thank you for your reply! I apologize for the belated response expressing my gratitude. it is in fact the 770 I as referring to. I’ll be completely honest, I’ve been playing Bridgestone j36 Pro combo for a long time and I came across the 770 second hand missing those two irons I spoke of. I will definitely take your advice and reach out to a certified Club fitter to possibly see if I can find replacement irons and if possible have these clubs fitted professionally for me. If not I suppose it’s time to start saving up for a new… Read more »

    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.

    Tom Wishon

    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,

    Mark Cowart

    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.


    Comparing details with PXG Irons now you were a slight Step ahead allready…
    I really liked the classic design head and sound of it.

    Tom Wishon

    Thank you very much for your comment. Yes, for those who followed my clubhead design career very closely, there were a lot of head design technology firsts that I did before the big companies did their version. There is a list on our website for anyone who may be interested in that. But no one really knows this because I have always designed within the component clubmaking industry where there is little to no marketing done to attract any attention to the companies and their developments. The 770CFE was intro’d in 2004 and was actually my 2nd iron designed with… Read more »

    Tom, I was wondering if you still have this head in a LH #5. This looks similar to the Tour Model forged cavity that you gave me when I left GS back in 2000. Unfortunately I lost the 5 iron and was trying to replace it.

    Tom Wishon

    ROXY Seriously is it THE Roxy from old Golfsmith days ??!!! How nice is that and I hope all is well with you. My apology for the delay in responding – the darn auto notification of posts to our blog was off kilter and I never realized it for several weeks. hate these digital things sometimes, which means I am showing my age there !! I had our warehouse people dig all around and while we found a left hand #4 iron in the 770CFE, there are no left hand 5 irons, very sorry. The newer 771CSI that replaced the… Read more »

    Any chance you still have a PW head in the 770 CFE line? Mine got misplaced in a move. Thanks Ron Manter

    Tom Wishon

    Ron First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that. I am sorry but after looking around the warehouse today, we have no more of the 770CFE irons around, either new or used. I can tell you that the 771CSI iron would be very compatible with the 770CFE from a pure performance standpoint. While the finishes are totally different the 771-PW could very easily blend in with the… Read more »

    Have you theses 770CFE left hand still in stock and if so what is the cost per head?

    Tom Wishon

    I am sorry but the right and left hand versions of the 770CFE irons were both discontinued this past year. They were introduced in our design line in 2004 and so they had a very nice run of years before their popularity waned to the point it was time to retire the model.

    These are just a fantastic set of irons. Too much offset for my taste, but that’s about the only knock I have against them. I (and others) have always felt that the large OEMs offered more technology in some of their designs than the component companies, but when these irons were introduced I knew Wishon offered just as much technology if not more. The longer irons can feel a bit harsh, but the forgiveness & distance will make you forget that. I think that if you want the best set of irons you can get (with more offset) then you… Read more »
