The Ultimate in High Performance Iron Design with CNC Machined Variable Thickness Titanium Face for High COR and Superb Off-Center Hit Forgiveness


  • Forged, CNC machined, variable thickness Beta-Titanium face design increases the ball speed to the highest possible level for an iron design.
  • Thin Beta-Titanium face design allows more weight to be removed from the face than is possible with a steel face to be used on the toe and heel areas to increase the MOI of the head for even better off-center hit performance.
  • Slightly oversize head profile automatically increases the MOI over more traditional iron head sizes to add even more to the off-center hit capability of the 870Ti.
  • 870Ti variable thickness titanium face increases the ability of the face to flex more to offer the same 0.830 COR as a driver.  Variable thickness face also increases off-center face flexing for superb off-center hit performance.
  • Low-offset hosel design allows a wider range of players to benefit from the super high performance design characteristics of the 870Ti.
  • Fully radiused sole grind with beveled leading edge provides the most playability for all levels of golfers from all types of lie conditions.
  • Available in RH in #3 – 9, PW, AW, SW, finished in bright satin polish.
  • Produced with post-2010 new USGA scorelines.

    “I am working on what would be a successor to the 870s but they’ll probably be too expensive for most people to care about looking seriously into because they will be forged, they will have a titanium body to go with the same SP700 face, and they will have a ton of tungsten ($$) on the body to bring up the head weight to normal levels and move the MOI into the highest range ever seen on an iron.” This comment has caught my eye. I currently play and love the 771csi irons. I am a huge fan of your… Read more »


    Hi, Tom. I know that these irons are older and discontinued, but they are my favorite and the bee’s knees. As such I’m hoping that you can possibly answer a question for me.
    Why do you think that my 870ti 4, 5, and 6 iron fly higher for me than a comparable hot-faced hybrid? I know that there could be many things causing this, but can you comment generally on your high-COR irons and how the face flexing affects shot height? I’ve had the same experience with your Sterling lower-lofted hot-faced irons.
    Thank you!

    Tom Wishon

    MATT Thanks very much for taking the time to stop by and ask your question. I too have always felt the 870s were one of the best irons I ever designed. The only thing ‘wrong’ with them was with the body made from 17-4 stainless they were really difficult to bend for lie or loft fitting requirements beyond a tiny tweak. That was in fact the biggest motivating factor for designing the 771CSI irons with a carbon steel body – although with those I had to use the high strength steel face and not the high strength Ti face because… Read more »


    Tom, Thanks for the reply! The 870ti version 2 sound fantastic! This may be a loaded and/or unanswerable in any concrete way since golf is so personal, but what is your opinion on what could help the average golfer more- a uber-high MOI, variable length, iron set with a good VFT face, or a single-length set? Does the variable face thickness and high(er) MOI of a set like the 870ti’s outdo a single-length set without those features for distance and dispersion consistency? I’ve tried a short set of Sterlings that were a pretty good fit for me and I liked… Read more »

    Tom Wishon

    MATT This’ll probably sound trite, but what helps the average golfer more is being fit PROPERLY. All of this great head design technology that abounds today is totally and utterly wasted when companies send golfers into retail stores to buy clubs off the rack that include 46″ drivers with no accuracy on lofts and no option for a different face angle, fwy woods that are also too long, hybrids that are too long and irons that have too low of loft. Honestly if you took today’s head designs and married them with the club assembly specs from the 1970s you… Read more »

    Justin Thanks very much for your support and for your interest. I do very much appreciate that. No firm date on the titanium and tungsten irons I am working on. Right now we are in the painful process of eeking out as much tungsten on the first 6 iron prototype as we can do. The whole reason for using soft titsnoum for the body of the iron is to create the chance to use a whole lot more tungsten than you could on a steel body iron. But now that some companies are experimenting with hollow steel body irons that… Read more »


    Thanks for the reply, Tom. I’m looking forward to it. Also want to give a shout out to Moe Hickey of Annapolis, MD at Clubs by Moe. He built my 771csi set, as well as a 14* 919 f/d, 950hc 5 wood, a full set of 775hs hybrids, and a full set of 590 dih driving irons. I have a nice mix and match of your clubs for any playing condition, and those clubs and a proper MOI match fitting by Moe have done wonders for my game. Always interested to see what designs you come up with next.

    If anyone is interested,I’ve got a set of 870 ti irons,5,6,7,8,9,pw for sale.inch shorter
    Open to offers

    John Agnew

    Are they still available and if so at what price and how are they shafted?

    Tom Wishon

    JOHN The 870Ti irons were discontinued several years ago to make room for the 771CSI high COR iron design. Please understand that all of the clubhead designs that I create for Wishon Golf are only custom fit by independent custom clubmakers around the US and world. There is no such thing as a standard shaft or grip for any of my designs because I only want my models to be custom fit, one set at a time for one golfer at a time. I recommend you head to the FIND A CLUBFITTER search tool to put in your location and… Read more »

    dan chionchio

    Scott, wondering if you still have the 870 ti iron set for sale.
    Thanks, Dan

    Tom Wishon

    I am sorry but we discontinued the 870Ti about 2 years ago after it had been a good part of our product line for around 6-7 years. Sometimes I forget that the big companies tend to only get 1 year out of a new model once it is introduced. I think about the only way one can find a set of the 870s is to hunt on Ebay. Ebay is the second largest golf retailer in the world now so you never know what you can find there until you search.
    Thanks very much for your interest,

    Susan Weiner

    I love my 870ti clubs. So forgiving and so long (thanks to Rich Hurley, the world’s best fitter). But now I want to add a 5 iron to my bag and the club’s are discontinued. I tried eBay and other online sites to find a used one without success. If I was to buy a single iron from current stock, which model would have the most similar characteristics and feel?

    Tom Wishon

    I am very sorry but we discontinued the 870s long enough ago that all the remaining odds and ends of inventory have been sold or liquidated. If you tried the online sites to no avail, I am sorry we can’t help you. In that case, the model most close to the high COR variable thickness face design of the 870 would be the current 771CSI. it’s not quite as large in head size as the 870, but the performance is right there at the same face performance level.

    Matt M

    I have a 3,4 and 5 iron that have very little use and would be willing to sell if interested.


    Do you have any of these club heads left in stock that I could order through my fitter?

    Tom Wishon

    I am sorry but we have no more inventory of the 870Ti irons in our warehouse. When we discontinued the model a few years ago, we liquidated all inventory of these heads. About the only thing we can suggest is to search on EBAY to see if there are any sets circulating there.
    Thanks very much for your interest,


    Hello, I was just fitted yesterday by Jacques Lavack in Winnipeg ,Mb Canada. I would just like to say that the fitting was wayyy beyond my expectations! I was there for almost 5 hrs and went through about 4 buckets of balls while we fine tuned everything from swing weight, shaft, club head styles, lie angles, basically everything that could be fitted , was. In the end I ordered the 870’s (6-sw) as well as the 919 driver and 3 hybrids. Took the 3,4,5 irons out of the bag! I can not say enough good things about the whole experience… Read more »

    Tom Wishon

    TYLER Thanks very much for taking the time to let us know what a great experience you had with Jacques in your recent fitting analysis. That right there is what real professional clubfitting is all about and how the most experienced fitters do conduct their sessions for golfers. And we’re so pleased to have Jacques working with us, representing our design line in his work, because I have known him for a very long time in this side of the industry and have always been impressed with his passion to do the best to help the golfers who come to… Read more »


    Tom thanks so much for responding to my inquiries. I am going to take a real hard look at the 870ti and the 771csi this evening. At the end of the night one of those heads will be making up my new set of irons. I love Wishon quality, the custom fit experience!


    Tom, Thanks for you response. Last night I went to my first fitting session and spent most of the time hitting the 870ti head with a couple of different shaft/length options. The fitter had a couple issues with the fittings holding the head in place on the differnt shafts so i was limited to trying only a few combos. He took video of my swing and then inputed some info into your software for a shaft match, but I am a little skeptical in terms of that being the final product based on the software. I thought the process would… Read more »

    Tom Wishon

    KEVIN Given that you say the clubfitter used video AND was consulting our shaft software data base for shaft comparison information, I would say that the fitter you are working with is a step ahead of most who fit golfers. Those things qualify as a bit of a more thorough analysis in a fitting session. While the guts of a proper fitting will always be working with the fitter to nail down your best lengths, lofts, lies, shaft, total weight, swingweight, grip type and size, IT IS CRITICAL that the golfer like the head model that he chooses or that… Read more »


    I was recently fitted for a set of 870ti, what Iam wondering is if you can answer two questions.
    1. Are the 870ti today the same as the 870ti that came out in 2009? If so have they fallen behind in technology compared to the new advancements the majors are claiming they have found in the last couple of years ( compare the titliest Ap1 muzuno ez jpx, ping g25)
    2. What is the main diff between the 870ti and the new 771csi, should I consider the newer 771 is it newer tech.

    Tom Wishon

    KEVIN Thanks so much for your interest! The 870Ti model is the same design with no changes that we introduced in 2009. I doubt seriously it has “fallen behind” in any aspect of its design technology in terms of both distance and off center hit forgiveness. Why I can say that is because when I was over in Europe giving clubfitting seminars for various European PGA organizations in the summer of 2008, I had the chance to visit the R&A’s technical department and have the final testing samples of the 870Ti irons officially tested on site for COR at the… Read more »


    I remember the Penick-Plus Ti faced irons you designed back in the 1990s or early 2000s. How do the new 870 Ti designs compare?

    Tom Wishon

    TOM Yes for sure, I remember the Penick Ti face irons you refer to. I’ll be totally honest. Back then in the mid 90s when I did this design, I only thought of using the titanium face to be able to increase the weight around the perimeter of the face, so as to increase the MOI of the head and offer a little better off center hit performance. Taking all that face area and putting a very light Ti face in there allowed us to put more weight around the perimeter of the head, which did definitely increase the MOI.… Read more »

    Chad Abel

    Was not convinced based on the catalog description, but after fitting several golfers to this design I am sold. These heads are gorgeous, forgiving (an understatement) and get the ball up quickly.
    That signature “click” has become very satisfying feedback for several customers. Well done Tom!

    I tell my customers these are the most forgiving heads on the market. If they want their bad shots to turn out better and get a bit more distance and height, these are the heads. Use these heads personally and notice the same results as my customers.. it’s increble how good shots are that are hit way off center! Also a great feature of the 870Ti’s is that they have a very traditional look from address for a forgiving iron, little offset and not a hugely wide sole. Only noticable thing is the heads are quite large, which one gets… Read more »


    the 870s are awesome.About club longer for me.easy to hit,look great, limited offset.

    Mike Baker

    I’ve played the 870 for several years now and my game has improved. A very forgiving and solid iron head. No reason to change.

    Peter Pachtner

    Very well performing club. The sound is somehow clicky, but you get used to it and then you know when you hit it dead center.
    Playing this head is like cheating. Off center hits don’t hurt because the ball still goes straight and long. Highly recommended for slow swing speeds, but works for all others as well.

    Tim Boedigheimer

    The 870 Ti irons are a great Wishon design. With the higher MOI from increased weight in the toe and heel area and beta ti face design for increased distance is a great fit for several golfers who have lost distance due to loss of flexability or suffer from bad backs or other injuries that prevent game enjoyment. These irons will give back lost distance and bring enjoyment back into playing the game.

    Voor de gemiddelde golfer is de 870Ti de beste keus. De eigenschappen van dit ijzer zijn zo superieur dat elke golfen eenvoudig lijkt. De consiotentie en vergevingsgezindheid die dit ijzer geeft vind u in geen enkel ander ontwerp. Voor mij is dit het best verkopende ijzer van de afgelopen jaren.

    Gary Duffey

    Built my friend a set of 870,s now I am in trouble he went from shooting in the low 90’s to high 70,s and beats me every now an then, last time I told him becarefull I will built me a set.


    These are the best irons that I have ever played. My game is more consistant and shots are straighter than with any club that I have ever played. Does not hurt that they are great looking

    You’ve seen the advert that says “It does exactly what it says in the box” well this head does exactly what it says it Tom’s video, above. Super distance, I used one club less than my previous set, great launch angle and boy does the ball stop on the green. Superb head. Thanks Tom.

    Agustin Sanchez

    Excelente diseño, todos los jugadores a los que les he fabricado un juego con este modelo, han mejorado sus resultados. Tiene muchisimo perdón de punto de impacto, pasa muy facil por el suelo, imparte mucha velocidad a la bola y consigue una trayectoria alta y larga.
