The Wedge Guy: The best golf club innovations?
Being in the golf equipment industry for nearly 40 years, I have paid close attention to the evolution of golf equipment over its modern history. While I’ve never gotten into the collecting side of golf equipment, I have accumulated a few dozen clubs that represent some of the evolution and revolution in various categories. As a club designer myself, I ponder developments and changes to the way clubs are designed to try to understand what the goals a designer might have had and how well he achieved those goals.
Thinking about this innovation or that got me pondering my own list of the most impactful innovations in equipment over my lifetime (the past 60 years or so). I want to offer this analysis up to all of you for review, critique, and argument.
Woods: I would have to say that the two that made the most impact on the way the game is played is the introduction of the modern metal wood by TaylorMade back in the 1980s, and the advent of the oversized wood with the Callaway Big Bertha in the 1990s. Since then, the category has been more about evolution than revolution, to me at least.
Irons: Here again, I think there are two major innovations that have improved the playability of irons for recreational golfers. The first is the introduction of the numbered and matched set, a concept pioneered by Bobby Jones and Spalding in the 1930s. This introduced the concept of buying a “set” of irons, rather than picking them up individually. The second would be the introduction of perimeter weighting, which made the lower lofted irons so much easier for less skilled golfers to get airborne. (But I do believe the steadfast adherence to the concept of a “matched” set has had a negative effect on all golfers’ proficiency with the higher-lofted irons)
Putters: This is probably the most design-intense and diverse category in the entire equipment industry. History has showed us thousands of designs and looks in the endless pursuit of that magic wand. But to me, the most impactful innovation has to be the Ping Anser putter, which has been…and still is…copied by nearly every company that even thought about being in the putter business. Moving the shaft toward the center of the head, at the same time green speeds were increasing and technique was moving toward a more arms-and-shoulders method, changed the face of putting forever. I actually cannot think of another innovation of that scale in any category.
Wedges: Very simply, I’ll “take the fifth” here. To me, this is a category still waiting for the revolutionary concept to bring better wedge play to the masses. The “wedges” on the racks today are strikingly similar to those in my collection dating back to a hickory-shafted Hillerich and Bradsby LoSkore model from the late 1930s, a Spalding Dynamiter from the 50s, a Wilson DynaPower from the 70s, and so on.
Shafts: Hands down, to me the most impactful innovation is the creation of the carbon fiber, or graphite, shaft. After fruitless ventures into aluminum and fiberglass, this direction has improved the performance of golf clubs across the board. You haven’t seen a steel-shafted driver in two decades or more, and irons are rapidly being converted. Personally, I don’t see me ever playing a steel shaft again in any club – even my putter! But beyond that, I’d have to say the concepts of frequency-matching and “spine-ing” shafts made it possible to achieve near perfection in building golf clubs for any golfer.
Wild card: This has to go to the invention of the hybrid. After decades of trying to find a way to make clubs of 18-24 degrees easier to master, Sonartec and Adams finally figured this out. And golfers of all skill levels are benefitting, as this is just a better way to get optimum performance out of clubs of that loft and length.
So, there’s my review from a lifetime of golf club engineering. What can you all add to this? What do you think I missed? I hope to see lots of conversation on this one…

Brandel Chamblee PGA Championship Q&A: Rose’s huge McLaren risk, distracted LIV pros and why Aronimink suits the bombers
PGA Championship week is here, and Brandel Chamblee did not hold back in our latest discussion ahead of the season’s second major.
In our 2026 PGA Championship Q&A, golf’s leading analyst made the case that PIF pulling LIV’s funding has left its players competing in a state of confusion, called Justin Rose’s mid-season equipment switch a huge risk at 45, and explained why Aronimink will be a bombers’ delight this week.
Check out the full Q&A below.
Gianni: With the PIF confirming that they’re pulling funding from LIV at the end of the season, what impact do you expect that to have on the LIV players competing at the PGA Championship?
Brandel: I would imagine that they have all been thrown into a state of confusion, and will be distracted, not knowing where they are going to play next year and not knowing exactly their road back to either the DP World Tour or the PGA Tour. Or in Rahm’s case, being tied to a sinking ship for the next few years, likely playing for pennies on the dollar in events that no one cares about or watches.
I doubt this would put him in the best frame of mind to compete at his highest level. Keeping in mind, however, that majors are the only time that LIV disciples get to play in events that matter, so never disregard the motivation they have to prove to the world they are still relevant.
Gianni: Justin Rose switched to McLaren Golf equipment mid-season while playing some of the best golf of his career. What do you make of the change?
Brandel: I don’t really know what to make of Rose switching equipment. It seems a huge risk on his part, even though it is likely, in my opinion, that the clubs he’s playing are similar, if not the exact grinds, to what he was playing previously, with a McLaren stamp on them.
Having said that, at best, it is a distraction when he seemed to be as dialed in with his game as any 45-year-old could be and trending in the majors to perhaps do something that would definitely put him in the Hall of Fame. At worst, given the possibility that these clubs aren’t just duplicates of his old set stamped with McLaren on them, he’s made an equipment change that would take time, and 45-year-old athletes don’t have the time to do such things.
Gianni: Aronimink has only hosted a handful of professional events since it hosted the 1962 PGA Championship. What kind of test does it present, and does a course with less recent major championship history tend to level the playing field?
Brandel: Even though Aronimink has only hosted a handful of meaningful professional events, it has been fairly discerning in who can win there. When Keegan Bradley won the BMW Championship on the Donald Ross masterpiece in 2018, he was the 2nd best iron player on tour coming into that week. When Nick Watney won the AT&T at Aronimink in 2011, he was 2nd in strokes gained total coming into the week.
In 2020, Aronimink hosted the KPMG Championship, and Sei Young Kim won. On the LPGA that year, she was first in greens in regulation, putts per green in regulation, and scoring average on the way to being the LPGA player of the year. And then there is the 1962 PGA Championship won by Gary Player, who eventually became just one of a few players to win the career grand slam on the way to winning 9 majors. It is a formidable test, and if it’s not softened by rain, it will bring out the best in the upper echelons of the game.
Gianni: Is there a specific hole at Aronimink that you think will do the most to decide the winner?
Brandel: The hardest hole at Aronimink in each of the three tour events that have been played there since 2010 has been the long par-3 8th hole, with the par-4 10th being the second hardest, so most of the carnage will happen around the turn, but with the par-5 16th offering opportunities for bold plays and the tough closing holes at 17 and 18, the finish is likely to be frenetic.
Gianni: The PGA Championship has always sat in the shadow of the other majors. What does the ideal PGA Championship look like in your eyes, and what would it take for it to carve out its own identity?
Brandel: The PGA Championship, to whatever degree it suffers from the comparison to the other three majors, is still counted just as much when adding them up at the end of one’s career. Almost 1/3 of Nicklaus’ major wins were the five PGA Championships he won. Walter Hagen won 11 majors, five of which were PGA Championships.
Tiger Woods twice in his career won back-to-back PGA Championships, and those four majors count just as much as the other 11 he won. The PGA may not have the prestige of the other three, but it carries the same weight. Having said that, I preferred the identity that it had as the last major of the year.
Gianni: You nailed your Masters picks. Rory won, Scottie finished solo second, and Morikawa surged to a tie for seventh. Who are your top 3 picks for the PGA Championship and why?
Brandel: I am not a huge fan of majors played on golf courses that have been shorn of most of the trees, although I understand some of the agronomic reasons for doing so and of course the ease with which it allows members to play after errant drives. However, at the highest level, it all but eliminates any strategy off the tee and turns professional golf into an even bigger slugfest. That means that it will likely be a bomber’s delight this week, but fortunately, Scottie Scheffler is long enough to play that game and straight enough to play it better than anyone else.
The major championships give us very few surprises anymore, going back to the beginning of 2012, so the last 57 majors played, the average world rank of the winners has been better than 15th in the world. So look at the highest ranked and longest drivers who are on form coming into the PGA Championship who also have great short games as the surrounds at Aronimink are very challenging. That’s Scottie Scheffler by a mile and then McIlroy and Cameron Young with a far bigger nod towards DeChambeau than I gave him at the Masters.

A putter that I love and hate – Club Junkie Podcast
In this episode of the Club Junkie Podcast, we dive into one of the most interesting flatstick releases of the year with a full review of the new TaylorMade SYSTM 2 putters. After spending time on the greens, I break down what makes this design stand out, where it performs, and why it has me completely torn between loving it and fighting it. If you are into feel, alignment, and consistency, this is one you will want to hear about.
We also take a look at some of the putters in play on the PGA Tour last week. From familiar favorites to a few surprising setups, there is always something to learn from what the best players in the world are rolling with under pressure.
To wrap things up, I walk through the process of building a set of JP Golf Prime irons paired with Baddazz Gold Series shafts. From component selection to performance goals, this is a deep dive into what goes into creating a unique custom set and why this combo has been so intriguing.

From 14 handicap to pro: 4 things I’d tell golfers at 50
This year my 50th birthday. Gosh, where has the time gone?
As a teenager in rural Missouri, some of my junior high and high school years felt interminable. Graduation seemed light years away. But the older I get, the faster life seems to fly by.
I’m also increasingly aware of my mortality. My dad died recently. Earlier this year, a friend and fellow PGA of America professional and I were texting about our next catch-up. The next message I received was news of his unexpected passing at 48. Shortly after, a woman I dated in college succumbed to cancer at 51.
Certainly, one can share perspective at any age. Seniors help freshmen, veterans guide rookies. But reaching this milestone feels like as good a time as any to do one of those “what would I tell my younger self?” articles.
I’ve had a uniquely varied career in golf. I started as a 27-year-old, average-length-hitting, 14-handicap computer engineer and somehow managed to turn pro before running out of money, constantly bootstrapping my way forward. I’ve won qualifiers and set venue records in the World Long Drive Championships, finished fifth at the Speedgolf World Championships, coached all skill levels as a PGA of America professional, built industry-leading swing speed training programs for Swing Man Golf, helped advance the single-length iron market with Sterling Irons®, caddied on the PGA TOUR and PGA TOUR Champions, and played about 300 courses across 32 countries.
It’s been a ride, and I’ve gone both deep and wide.
So while I can consult and advise from a lot of angles, let me keep it to a few things I’d tell the average golfer who wants to improve.
1. Think About What You Want
Everyone has their own reason for picking up a golf club.
Oddly, as a professional athlete, I’m not internally driven by competition. That can be challenging, as the industry currently prioritizes and incentivizes competition over the love of the game.
For me, I love walking and being outdoors. Nature helps balance my energy. I prefer courses that are integrated into the natural beauty of their surroundings. I’m comfortable practicing alone. I’m a deep thinker, and I genuinely enjoy investigating the game, using data and intuition to unearth unique, often innovative insights. I’m fortunate to be strong and athletic, so I appreciate the chance to engage with my abilities. Traveling feels adventurous. I could go on.
You don’t have to overthink it like I do. For you, it might be as simple as hitting balls to escape work, hanging out with friends, and playing loosely with the rules and the score.
The point is to give yourself permission to play for your own reasons, and let that be enough.
But if improvement is your goal, thinking about your destination—and when you want to get there—is important, because it dictates the steps you need to take. When I set out to go from a 14-handicap to the PGA TOUR as quickly as possible, the steps I needed were very different from those of a working golfer trying to break 90 in six months. That’s also different from someone who just wants a few peaceful hours outside each week, away from work or family.
None of these goals are better than the others, but each requires a different plan that you can work backward from.
2. There Are Lots of Things That Can Work
One of the challenges of golf is that, although there are rules for playing, there aren’t clear, industry-wide standards for how to best play the game. There’s a lot of gray area.
You might hear a top coach or trainer insist that a certain move is the best way to swing or train. Then you dig a bit deeper and, much to your confusion and frustration, another respected coach or trainer says something completely different. I don’t think anyone is trying to confuse you—at least I hope not. It’s just where the industry is right now.
You have to be careful with advice from tournament pros, too. They might be great at scoring, but they’re also human and sometimes just as susceptible as amateurs to believing things that don’t really move the needle. Tour players might describe what they feel, but that’s not always what they’re actually doing when assessed with technology.
I recently ran a test on my YouTube channel (which connects to my GolfWRX article “How to use your hands in the golf swing for power and accuracy”), and, interestingly, two of the most commonly taught hand actions produced the worst results in the test.
Coaches can certainly help. If you find someone you connect with to help navigate, that’s great. But there are many ways to get the ball in the hole. In the current landscape, you may need to seek multiple opinions, think critically, and use your own intuition to discern what seems true and whose advice resonates with you.
I’d recommend seeking someone who is open-minded and always learning, because things constantly change. Absolutes like “correct” or “proper” should raise a red flag. AI can be useful, but it tends to confidently repeat popular advice, so proceed with caution.
3. Get Custom Fit
If you’re serious about becoming a better player, getting custom fit is hugely important. There’s no sense fighting your equipment if you don’t have to. Most better players get fit these days and, if they don’t, they’re usually skilled enough to work around clubs that aren’t ideal.
If you plan to play for a long time, it’s worth spending a little more upfront to get something that truly fits you and your game, rather than continually buying and discarding equipment.
Equipment rules haven’t really changed significantly since the early 2000s. To stay in business, manufacturers keep pushing those limits. If you pull a bunch of clubs and balls off the rack and test them, you’ll find differences. I’ve tested two new drivers and seen a 30-yard total distance gap. Usually, the issue isn’t bad equipment; it’s that the combination of components simply isn’t the best fit.
It’s like wearing a new pair of floppy clown shoes. Sure, they’re shoes—but you won’t sprint your best in them compared to track shoes that fit perfectly.
Be wary of what’s called custom fitting, too. Sometimes the term is used as a marketing strategy rather than an actual fitting. In some retail settings, fitters may be incentivized to steer you toward higher-priced components. That doesn’t automatically mean it’s not the best fit, but you should be aware of potential biases.
I learned a version of this lesson outside of golf. Years ago, I bought a tennis racquet at a big box store from a seemingly knowledgeable employee who thought it would suit me best. The racquet gave me tennis elbow, and I spent months recovering with rest and acupuncture. The next season, I invested more time and money to find what actually fit me, and I walked away with something amazing that I still play with years later.
So if you’re going to get fit, be smart about it.
Find someone you believe has deep knowledge—possibly with certifications, but not necessarily. Make sure there’s a wide inventory across many brands. Check recent reviews for the individual fitter if possible. Make sure you trust that the fitter has your best interests at heart. If they’re wearing a hat or shirt with a specific brand’s logo, proceed with caution. Unless you specifically want a certain brand or look, be wary of upsells, especially if two options perform nearly the same.
Also, while golf is called a sport of integrity, there’s a thread of manipulation in the industry. I once drafted an equipment article for an industry magazine, structured just like one of their previous popular stories, with matching word count and great photos. The assistant editor loved it; it was useful to readers and required little work on his part. But the editor-in-chief nixed the story. When I asked why, I was told it was because I wasn’t an advertiser. It turned out the article I’d modeled mine after was a paid ad cleverly disguised as editorial content.
I really dislike games, clickbait, and fear-based manipulation. I hope this changes, but golfers deserve to know it exists.
4. Distance and Strategy Matter
There’s a real relationship between how far you hit the ball and your scoring average, even at the PGA TOUR level.
I experienced this early in my pro career. I started as a power hitter, swinging in the high 120s and breaking 200 mph ball speed with a stock driver.
Back then, some instructors advised swinging at 80%, so I tried slowing down for more accuracy. That worked fine on shorter, tighter courses. But on longer setups, I was coming into greens with too much club, and par 5s stopped being

Oops, hybrid description flew OB! The early 2000s did NOT herald the invention of the hybrid. Rather, it marked the return of the Bulldog, a trouble club from the late 1800s through hickory age. The Bulldog had a very small head – exemplified by a clubface the width of two golf balls … a shorter shaft and about 25* loft… and was used to chop the ball out of moderate rough.

The ball has seen a big change. If you ever played balata you would agree. The new balls are longer and straighter and don’t smile at you after hitting it in the belly with your sand wedge.
Daniel Poehler

Good article, Terry. One innovation that I believe we can add is the addition of grooves to the face of putters to start the ball on a forward roll as soon as it’s struck as oppose to a skid then roll. I believe the “Yes” putters started the trend and now vertually every manufacturer has their version of this.

I would say hollow head drivers and perimeter weighting in irons and putters for sure but in terms of evolution it has to be the golf ball. From gotta percha to the Haskell to balata to today’s urethane the ball goes further, straighter and lasts longer because it doesn’t cut.
Scott
Jun 27, 2019 at 5:15 pm
yes, the ball. Maybe the biggest change of all, not even on the list.
Terry Koehler
Jun 28, 2019 at 10:01 am
I can certainly agree, Scott. But I was focused on clubs with my list. There is certainly no question that the evolutionary/revolutionary changes to the golf ball have impacted the game a great deal, maybe more than all the things I listed combined!!!
Good call.

I concur with the larger headed drivers as being very influential. I’m not sure of its size compared to today’s 460 cc limit, but the first time I remember hitting my Biggest Big Bertha , I swear I thought I was cheating. How could you miss these things I thought? The ball looked like a pea sitting there on the tee next to that head.

The best golf club innovations? The slot. Thank you Wilson, Adams, and Nike, or anyone else I have failed to mention. Put one with the secret sauce in a club face and the ball goes further. Plus it keeps errant shots from going too far off line while also expanding the sweet spot for hacks like me.

For all the club improvements I understand handicaps have not followed suit.
Doug
Jun 25, 2019 at 12:54 pm
Terry, sole grinds evolved with turf conditions. I’m not sure what the club would be that was the revolution, but my limited knowledge points me toward Ping irons with wider soles for more effective bounce and a lot of radius along the leading edge. When fairways got more plush, those irons delivered improved turf interaction for a lot of players. Your own wedge designs reflected improvements that have been much copied in modern iron soles. A lot of attention is now paid the bottom of iron heads and you had a big part in that.

Not just the metal wood, but the 460cc driver complete with all the innovations that led to increased trampoline effects, improved forgiveness, and the max COR limit. Also, the large number of options in high-MOI mallet putters, not just Ping Anser style.
Greg

Can you expand upon your thoughts regarding this:
But I do believe the steadfast adherence to the concept of a “matched” set has had a negative effect on all golfers’ proficiency with the higher-lofted irons
Johnny Penso
Jun 25, 2019 at 8:47 pm
That statement would make more sense is he had said, “proficiency with the lower lofted irons”, meaning, many players would probably benefit from a 4-6 hybrid in place of a 4-6 iron.
Jake

Thought the same thing. If he did mean proficiency with wedges, etc. would be good to have a little explanation. ???????

I would argue that the modern (sand) wedge itself was the innovation, the bounce and sole was a huge benefit to golfers.

I’d say the Innovation of moving from wooden to steel shafts changed the game more significantly across the board when compared to graphite innovations
TR1PTIK
Jun 25, 2019 at 2:48 pm
I’d beg to differ. The ability to create more diverse profiles via graphite makes it the more significant innovation. The only major drawback of graphite shafts is a lack of weight for higher swing speed/stronger players who need it and even that is starting to be addressed.
