The 585PC (Progressive Cavity) irons are the next generation of true forged carbon steel irons from Wishon Golf. As the first company to use CNC machining to create the entire back design of a forged iron with the 560MC in 2007, Wishon Golf has expanded on this with the 585PC, using a unique progressive design across the set.
- 585PC combine a progressive cavity back design on the #4 to 7 with a progressive muscleback design on the #8 to AW, with each iron’s back design fully created by CNC machining to achieve a precise position of the CG in each iron.
- The 585PC cavity back #4 to 7 iron demonstrate a progression of the major rear mass below the back cavity from lowest on the #4 iron, slightly higher with each iron to the #7 iron. This keeps the CG lower on the low loft irons to enhance launch angle and spin.
- The 585PC muscleback #8 to AW present a gradual vertical rise in the mass of the muscleback to slightly raise the CG to optimize shot height as loft increases to prevent ballooning of the shot.
- The 585PC are first 5-step forged from soft 1035C carbon steel before each back design is fully created by CNC machining, to reduce internal voids which results in superior impact feel.
- The U-groove scorelines of the 585PC are individually CNC machined under 2010 USGA/R&A guidelines and are fully conforming to the Rules of Golf.
Hello. Is this “Heads-only” ? In that case I would be interested in buying PW – 6 iron. Would that be possible ?

Hello, are the 585PC irons available in left hand?
I am very sorry but no, we just do not have the size of overall demand to justify the much, much higher tooling die expense of forging dies for a left hand model. Forging die costs are over ten times more than the tooling costs of doing an investment cast iron, sad to say. I do wish that were different.
Had my fitting for a set of 585’s from 4-p and 3 309hcg wedges done yesterday. Being built by arnaud maurin 33golflab in bordeaux france. Can’t wait to get my hands on them. They look fantastic and feel great!
That is great to hear and I’m excited for you to hit your first shots with the new clubs! You did right by choosing to work with Arnaud . He is a good friend, I correspond with him a lot over golf technical matters, and I know the fit you went through with him will result in clubs that make you pleased! Best wishes in this great game and thanks so much for your support!
Hi Tom, I’ve been playing your designs pretty much from day one: Penick Professional Tour then EQ1-NX’s. Last year, on a whim, I played a set of old forged Hogan’s and was hooked the first time I hit the 5 pure. I’ve recently acquired my Dad’s old Golfsmith Tour Cavities (Cast, similar to your 550c) and am really enjoying the feedback from them. I wanted to ask your opinion on a new technology that I haven’t seen you use yet: Polymer filled cavities (a’la PXG). This, along with tungsten weighting, seems to be the new rage in iron design. Wondering… Read more »
ART To be honest with you, hollow irons, whether polymer filled or not, are not new at all. I remember one of the first such hollow iron models was an iron designed by Ralph Maltby for The GolfWorks back in 1984. I know this because I worked for Ralph back then and was part of his first test project team for those irons when they were in development. Among the newer generation hollow irons that began to show up around 2018, PXG was not the first to re constitute this type of design. They just jumped on the bandwagon like… Read more »
Hi Tom, just wanted to compliment you on these great new irons. I had the chance to hit them when I attended Daimond Golf’s Art Of Clubfitting course earlier this month and they feel tremendous. Definitely on my want list
Tom, I’ve had a 585PC 7 Iron built @ 37.25″ and I am looking at adding 8 – PW and will continue from the 7 iron length and deduct 3/8″ between clubs and adjust head weights to achieve moi matching. Since the lengths will be longer than using 1/2″ between clubs would it make any sense to increase loft difference between clubs to 5 degrees- 8i (39 degrees), 9i (44 degrees) and PW (49 degrees. Or maybe 4.5 degrees between clubs? Thanks.
In ANY set of new irons, I would recommend finishing the build so it fits you and your swing and feel characteristics and then go out and hit shots and play with it for a few weeks, taking time while you do that to reflect on distance gaps, shot heights. Then if you notice anything that you feel could be remedied, corrected or enhanced by a loft change, that’s the time to do that ,if necessary. Not before you go out and spend some time with the irons.
Tom, you are the man! I have loved every set of clubs I have built with your designs. 951xa’s awesome! The old 550Ms, great! The 550Cs, great! I managed to track down two brand 715CLC driver heads years ago, and I absolutely love this driver!
These 585PC club heads look amazing!! I can‘t wait to try them!
As you can tell I am a big fan of your designs!
Thank you for all of your contributions to the game of golf!
Wow, that is very humbling to hear your very kind remarks about my work. I am just a guy who VERY fortunately was able to discover almost by accident, how much I was into golf clubs and how much fun it would be to pursue a career in that field. Thank you, and the very best to you in this great game!
Tom, These look beautiful. Are these considered one piece forged iron heads? Paul
Yes, as with all of our forged carbon steel iron heads, they are all one piece construction. Not hollow. Each head is first forged in a raw head with no cavity on the back. Then we CNC machine the entire back cavity of each head so the cavity design is precise and the center of gravity position is as precise as can be made.
