DESCRIPTION

Details

Modern performance in a clean, traditional shape.

The SMT 579 Iron is designed for golfers who want modern distance and forgiveness without sacrificing a confidence-inspiring look at address.

Built using hollow-body construction and a thin 455 Carpenter steel face, the 579 promotes efficient face flex to help maintain ball speed across a wider portion of the face. A low center of gravity supports a controlled mid-to-high launch with playable spin, making it easier to produce consistent approach shots throughout the set.

Stability, feel, and consistent ball flight.

Internal perimeter weighting enhances stability, while proprietary internal foam improves sound and feel at impact. These design elements work together to provide a solid, responsive feel without excessive vibration.

Designed to look and play the way better players expect.

Despite its modern construction, the 579 maintains a classic profile with a slim shape, progressive offset, and brushed finish that reduces glare and visual distraction. A refined sole design helps the club move cleanly through the turf for more consistent contact, while still allowing the ball to be worked when needed.

The SMT 579 is built for players seeking added performance in a compact, traditionally styled iron.

Such a pleasant suprise
Ok, I don’t normally stray far from a forged blade combo set for the last 20 years, but these clubs are good. I’m kind of pick about the the soles on clubs as I am a ‘Picker’ of the ball can fat soles on irons are a problem for me to play all the touch shots I like to play. I’ve bagged these for about 4 rounds and I can say they hit all the shots I want to hit and have acceptable distance and do not pull to the left. I’m nolonger a single digit HC, but I can still on occasion string a good 9 together. These are a delight to play, I can work them , I don’t get the dreaded ‘SOLE BOUNCE’ from on hard lies… They are forgiving but not so much that it’s always a straight ball flight. Distance wise there are about where i want them for my age. It’s not overly long, not short of my other clubs… but a bit less pulls and pushes. Great clubs

SMT 579 Irons
Got a set via the web, very easy to customise (Recoil shafts, flat lie) and met all my needs.The club looks like a butter soft blade, is meant to launch like a cavity back, and in the end plays somewhere in between. It has the higher launch of a CB and is forgiving, but that means it's not as penetrating as it's strong loft suggests. Distance is adaquate (an old Rolls Royce pun...) by 2023 standard rather than exceptional.All in all a very satisifying set!

Look Great
These irons look great! Overall finish is top notch. Had to deburr one of the hosels a little extra to get correct insertion depth but other than that no issues. They are foam filled and the weight/plug screw is threaded not a fake screw. Can’t wait to see how they perform.

Smt 579 iron review
Overall so far these irons have been much more than I expected. You simply cannot go wrong for the price offering. I’ve gamed some other direct to consumer irons and although mostly moderately priced I still feel the value on the smt’s is unmatched. The aesthetics and the performance are top tier. I’ve already had many questions about what’s in my bag, some before ever seeing a shot based on looks, and some when I’m asked “what did you hit there?” And my response usually garners the question of “what the heck are smt’s?” Love these irons I also have the 4 hybrid which I would highly recommend as well. Job well done SMT

Major brand killer!
As an owner of a set of P790s and G410s, I bought a set of the SMT 579s to mess around with without any major expectations. Clubs came incredibly quick and was able to slap the heads on a set of AMT White X100 shafts. At setup, swing and follow through the 579s feel exactly like their major brand competitors. I have used these for a few practice sessions and a couple rounds. I haven’t had any “flyers” or “hot shots” off the face. They feel absolutely amazing. For a fraction of the price you are getting an amazing product that matches any of today’s iron technology.

Irons
They feel amazing! They are the best irons I have felt nice and light and for a cheap price they feel just like p790s and my ball striking hasn’t been better. I love them

A Surprising Value Iron Set
I started with the 579 A Wedge to fill in another iron set. Likes it so much I ordered the 6 thru PW 579 heads which I matched with some shafts I had on hand. Liked them enough I bought the SMT 3 Utility iron and now just ordered the 579 5 iron head to complete my irons (at lease thus far). These are really fun clubs to hit, reasonably forgiving with a rocket off the face performance and terrific value at their price. So glad I took the first leap and where it has led me.

Amazing @ an Amazing Price
Built a set of the 579 irons for myself. Was so impressed, I bragged to my brother. Built another set for him. He also loves them. Super workable irons at a real nice price.

Love these irons!
I am so glad to have found SMT once again! Used their products back on the early 2000's. These irons are beautiful and feel great. My third round playing them was on our clubs Senior Championship. I didn't win (3rd place), but I did shoot my lowest round of the year, 77. I have a feeling these will be in my bag for a long time!

Second review 2 yrs later
I don’t normally do 2 reviews of something. But this qualifies a SMT built this set for me. In 2023 I had a set of these irons for a half season, but as I usually do I give them over to the ‘First Tee’ in the area for the kids. Well I’m retired now and dont build clubs much any more (maybe a wedge..eh). So I needed something that I could trust and I liked these heads a few seasons ago. So I called up SMT and had them make me a set in a Senior shaft with their Advent shaft and and then a matching set of woods. Well I can say that the irons hit straight and are comfortable with a nice ball height (which was a concern). I’m not going to say I picked up 10+ yards… That does not happen for me on irons. But my knock down shots and pitch shots were dead on as well as a couple of 7 irons for the par 3’s . All in all, these are keepers….. again.
