870Ti Irons

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

Features:

  • 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.

  1. 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.

  2. 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.

  3. 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

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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 used to VERY quickly. They have a very distinct sound/feel to them. A bit of a click from the thin titanium face.
    Bottom line – The longest and most forgiving heads available(and in my opinion they look great)!

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

  10. 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!

  11. Tom.
    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?

    Thanks.

      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.

      But back then we were ignorant to the possibility of using the titanium to increase the COR of the face to increase ball speed and distance. For one, no one in the industry in the 94-95 time period was aware of COR – the USGA’s rule limiting it did not even come about until 98. So we never thought that it could be possible to use the greater strength to elasticity property of titanium to increase the COR and distance of the shot.

      For me, this realization that it could be possible to increase the COR of the face of an IRON came about in 2000. Since that time I have been able to design three other irons with thin face/high strength to elasticity materials to increase the COR and distance.

      So the BIG thing with the 870TI vs the old Penick irons is that the 870s do definitely have a tested and verified COR of 0.830 – right at the limit of the rules. The Ti face in the Penick irons was made thicker which effectively stopped the face from having a COR that was any higher than what had been the norm with all previous thick face cast stainless irons. Add to the higher COR of the 870 the fact that the variable thickness design of the thin TI face also GREATLY improves off center hit distance and you have an additional plus for the 870 over what the Penick Ti face iron had.
